Funny thing is they are only 3 hrs drive from my house.

I'm actually going through his town Friday.

I have 2 Renishaw TP2's, they are surviving my inexperience so far. M2

Renishaw makes a sacrificial breakaway adapter, essentially a short piece of

I went to the web site, very sparse with its data, but that is a decent
enough price, that I wonder what the shipping may be, and from where?

Yes, I use standard 4mm screw probes. Perhaps us$50 is "reasonable" but I'm 
just a hobbyist/retiree and I find that breakage due to stupidity annoying. I'd 
rather spend a similar amount on a decent bottle of wine!

Their probes look gorgeous but technical information on their website is 
sparse. I'm interested in any information on their design and particularly, if 
it is patented, the patent number. I'm intrigued by probe designs and have 
built experimental units using strain gages, FSR (Force Sensitive Resistors) 
and...

Hey Ken,

I believe so, but I'll find out from the manufacturer to be absolutely sure.

I'm reference to your other comment about breaking probe stylii, have you 
checked out fleabay? They seem to have relatively decent priced units
(40-50usd) if your probe is renishaw or compatible.

Does anyone know if verser probes are still shipping and making probes?

I know the owner is a fellow Linuxcnc guy so keen to support him plus there
probes look awesome.

Maybe my emails are bouncing.  But just wondering if anyone knows what they
are up to currently.

And if anyone has used their probes.

And finally.  Any other good probe brands to try that are good value for
money.  And accurate.

I started to get into the new qtpyvcp screens which is why I'm looking at
auto probing now.

Which is why I suggested using the in_not pin if its available. The 
spindle is generally grounded and using the bit of pcb for a contact 
results in a logic 0 on contact. Feed that into the in_not pin.
If using a std bob input the not module MUST be above anything in the 
addf order hat uses it else the approach velocity error gets out of 
hand, and you may damage the pcb with the first approach from the 
resultant servo-thread timed overshoot.  I also invert that when hole 
finding where I have a 3/4" teflon rod holding a length of 12 gauge 
copper wire with the probe wire separated into half the strands on 
either side of the probing wire and twisted back together. I run the 
spindle backwards at 500 or so revs, and probe all 4 quadrants then 
center it both ways and touch off. And I regularly can rerun the 
holefinder code with no more than .0002" of error either way the 2nd 
time. There, because the probe is spinning, I have a capacitor on the 
probe input that is discharged by a microsecond contact, and still has 
not recharged the capacitor by the time the servo-thread read rolls 
around at the next random millisecond.

But because my spindles aren't fixed, I use the pcb method for setting 
TLO's.

Where are you reading? The G38 docs don't talk about opening or
closing, they talk about contact and loss of contact:
http://linuxcnc.org/docs/2.8/html/gcode/g-code.html#gcode:g38

The HAL pin probe-in should go high on contact. How that is achieved

Yes, been doing exactly that for years Alan. If using a mesa interface, 
you may be able to "net" it to the in-not pin and skip the invertor as 
its one less thing to worry about in your addf order.

[Emc-users] Probe with PCB piece

2020-11-16 Thread Alan Condit
Hi,

I want to set up to probe for workpiece height (tool length) with a piece of 
PCB  and a wire hooked to probe input and another piece of wire and an 
alligator clip wired to probe ground.  I would clip the alligator clamp to the 
tool and set the piece of PCB on top of the work surface. So, the circuit would 
close when the tool tip touched the PCB. However, when I read the instructions 
on G38.2 it talks about the switch opening. Can I invert the probe signal and 
use it for switch closing? 

Thanks,
Alan

If its truly a fixed value, how about

#<_probe_len>

These are not cleared when you load a different bit of gcode, so one 
could add it to one normal preamble, ran once as the lcnc machine has 
been rebooted, I don't 100% trust that it would survive a cold reboot.  
With hot reboots, the actual survival rate of stuff like that was quite 
good, amazing me at the time I discovered it, several years ago.

Mine however is a piece of 10 gauge copper wire, buried in a 3/4" 
diameter teflon rod, which has no stop collar.  I use it far more often 
in finding and establishing the exact center of a hole so everything 
else can then be calculated from there.  If I need to find a Z position, 
I put a .0625" thick pcb on the work, use the real cutting tool, usually 
rotating backwards, and add that pcb thickness to get the tool at 
contact=0..

I have yet, when the probe circuit is working, to put a visible mark on 
the piece of pcb, the contact is that gentle, and I usually have a .2 uf 
cap across the contact so a momentary contact is saved long enough for 
lcnc to register it.  That improved its repeatability quite a bit.

Ahh, yes, the miss is reported. Now the light of comprehension comes on.

I don't know of a way around that, and IMO the miss should not be an 
error, but a return value so far out of range that ones software can use 
it for an error flag as you tried to do with the 'else' above. But the 
error catcher in the g38 code won't let it work.

Perhaps something can be added to the G38 call that would make that the 
g-code writers choice?  I'd be very happy with that option. The stopper 
error in the g38 miss condition as it exists now is a PIMA. It should be 
our choice.

Yeah I wanted to refer to a .ini parameter.  Wasn't sure how, on my 
to-do list.  So I can refer to .ini parameters inside g-code? 
Z#<_probing.probethickness>  or what?
Point is, probe tool is 1.826 inches thick, so once it touches off it 
needs to fix the z-offset for that point to be 1.826 so z=0 is the

It's if the probe cycle fails to trip.  If the probe gets found in the 
acceptable travel, all is well.
If the probe travel limit is reached, the error condition dumps out of 
the .ngc code and for some odd reason the Axis UI ends up with the MDI 
tab selected.  Well it's not incomprehensible, Axis tried to run g-code 
and got an exception condition.  But it's a problem, not a show-stopper 
but I did aim to make the pendant control essentially everything but 
file selection with minimal need to use the terminal.

It is on an older version of LinuxCNC that I should update sometime, hoping

Coding style. did you mean -6.5 - #1? I always use a space around a math 
function char, reducing the ambiguity when I go back and read it 
months/years later.

> G10 L2 P0 Z1.826

This also is a coding style preference, but I have gotten out of the 
habit of adjusting the G54 map.  It reduces the hunting while looking 
for a map that matches the one originally homed to mapping, for me at 
least.  So I wind up using the next 2 or 3 maps in most of my coding.

This also is a disadvantage because, realizing the machine is going to

G54, and unless you know what map was in use, you lost the data that 
would tell me my math was funkity or THAT map was funkity because my

This to me is a very strong argument in favor of separating global data

I imagine that you have the pendant connected to one of the
MDI_COMMAND HAL pins? Those use MDI, and switch to the MDI window.

How doe the pendant interface to LinuxCNC? wheel-jogging appears to
work regardless of manual/mdi mode

You could toggle the halui.mode.manual pin to return to manual mode.
However that doesn't switch tabs in the Axis GUI, so I am not sure if
it has the required effect.

[Emc-users] Probe cycle switches to MDI

2016-10-08 Thread Danny Miller
I have the wireless pendant button triggering a probe cycle in an .ngc.

Problem is, IF the cycle ends without tripping the probe (user error), 
Axis UI ends up switching to MDI tab, and all the pendant function is 
for Manual Control tab.  So it disables the pendant until you can get 
back to the PC and fix it by clicking back to Manual Control tab.  Why 
does it end up in MDI tab, and how can make LinuxCNC end up back in the 
Manual Control tab?

.ngc code below:


o100 sub

G38.3 F50 Z[-6.5-#1]

I find that it's the easiest thing in the world to shorten a Haimer 
short probe tip (approximately 25mm long) by about 20mm, give or take.

CLIIINK!

#$@%  @#$%^  son of a  $@*#!

They should sell those $45 probes tips in handy packs of ten.

There's even a sign that comically commemorates this all too frequent 
sinking feeling.

https://saundersmachineworks.com/collections/all/products/it-has-been-days-since-we-broke-a-haimer-tip



I saw a YouTube video that described how to remanufacture similar 
Tormach probe tips using ceramic rod and epoxy.  The ball diameter is 
critical, but the misalignment of the rod can be nulled when the new 
probe tip is installed.

https://www.youtube.com/watch?v=59q8fZ9GV8E



Today's Million Dollar Product Idea:  Sell a $50 replacement probe tip 
that's designed to have the ceramic rod swapped in under a minute.  Keep 
the expensive parts on the top and bottom and only replace the 
sacrificial rod in the middle.  The kit includes ten spare ceramic rods, 
and ten packs of rods sell for $20.  Why aren't these probe tips 
initially designed this way?  I suspect it has something to do with the 
movement of small pieces of green paper. $$$

No, of course not!  Blum has their own style for the 
threaded end, it has a 6mm cylinder just below the 4mm 
thread, to center the probe.  A Renishaw-style probe tip 
MIGHT just barely work, but it would not fit well.
I'm still trying to figure out how they attach the ceramic 
rod to the threaded end.  I'd like to shorten my probe by 
50mm or so.  If it is just epoxied in, I might try heating

I'm going to hook up a watchdog to stop motion when the IR

Well, we will see how long it takes me to have my first

Well, how do I modify it?  Like I say, pressing Probe Z momentarily 
starts an ngc.

My best guess is the probe input needs to AND with "isAuto", does that 
sound right?  I don't think I saw the probe trip during g-code running 
(which would be weird if it's to protect the probe).

You wouldn't think that if you ever ran the business end of a $500
probe into the side of a vise while jogging

The normal behavior is to protect sensitive and expensive equipment.
If you don't like that, you can modify it using HAL logic quite easily.

I think it is to save the probe if you leave it in the spindle by accident and 
press "cycle start"

You should be able to interlock it by and2 with motion.motion-type == 5

http://linuxcnc.org/docs/2.7/html/man/man9/motion.9.html

Motion-type is S32 and the "comp" component needs float, so you will also want 
a conv_s32_float too

[Emc-users] "Probe triggered during jog"

2016-09-07 Thread Danny Miller
I have a wireless toolsetting probe here.  It's nice, but it's naturally 
sensitive.  Even when you're not using it, very easy to trip, and 
LinuxCNC generates a "Probe triggering during jog" error.  Just bump the 
table.  The probe doesn't even have a physical hard switch, just the plate.

Hmm.  I don't know why it  was coded to do this, but it's a problem. 
Basically it should be ignoring Probe-in if it's not probing.

How can I stop this?  I should probably AND the signal with one that 
says it's actually in a probing cycle.  Thus if it's not running the 
probe ngc, the AND output isn't true and LinuxCNC won't see a probe trip 
even if you genuinely trigger the probe.

So the probing cycle button (momentary) triggers an MDI command which 
starts an NGC.  As best I understand it, AND requires a HAL net.

And HAL nets can't be assigned in g-code, can they?

Can an MDI line assign a HAL net?

Can an MDI line do things in addition to calling the ngc, or is it 
single-op?  What would the syntax be?

The ProbeStart button is  only a momentary.  I believe it can set a HAL 
net and trigger the MDI on the same line, but is there any way to signal 
back to the HAL at the end to set this net to disable the Probe-in signal?

This seems similar to the question I had before about how you might set 
up ProbeStart to operate as a deadman button, but I haven't yet tried to 
go through this.

So you probe down until the switch on the Z assembly touches the work, 
and you use that Z level as your "top of material"?  That sounds good.

Interesting idea.  So you would use something like this (.hal pseudo-code):

Z-switch-in => motion.probe-input
((motion.motion-type != Probing) && Z-switch-in) => axis.Z.neg-lim-sw-in

I can't think of a reason why that wouldn't work.

It will mean the -Z soft limit is wrong since it is statically set to 
the largest possible value in the ini file, while the actual hard limit 
moves up and down as you load materials with different thickness on the 
machine.

I wonder if you can set ini.Z.min_limit to the probed Z value as part of 
your "find the top of material" subroutine.

I'm not sure how that would all behave, but i'd love to hear your results!

[Emc-users] Probe switch / limit switch

2016-04-12 Thread Jim Craig
I am helping a buddy build a plasma cutter. The z axis assembly we are 
using includes a probe switch so that when the torch tip moves up a 
slight amount relative to the normal torch position it will trip the 
switch saying the torch is on the metal to be cut.

It is simple enough to use this switch as a probe switch and we will do 
so. However I would like to use it as a z-axis limit switch when a probe 
move is not being conducted.

Is there any reason I cannot use the motion.motion-type pin to disable 
the switch as a limit switch during a probe move? It is stated in the 
man page that it is a debugging pin.

Is there a better way to do this?

What say you?

Thanks,

Jim

It has one feature that I like.  The $25 replacement ruby tip probe is 
half the price of the replacement probe tip for the Haimer Zero Master.  
They should either sell the replacement probes in packs of a dozen for 
$100, or give away the Haimer to ensure future sales of the delicate probe$.

The http://deepgroove1.com page made a big deal out of the high tech 
contact material that allows more switch contact operations before 
carbon buildup results in switch failure on their probe.  If we wired 
probes with three wires (+V, COM, and the probe signal) instead of just 
two wires for switch contacts, we could have some active electronics in 
the probe and use some optical or capacitive or inductive non-contact 
method to generate the probe signal without any contact degradation.

There are three set-screws to fine tune the centring of the probe. Check
out video 4 on http://www.wildhorse-innovations.com/support/EPAssem.html
but alignment is one of the reasons Gary stopped shipping it as a kit.
Needs care during assemble to get things close to central.

Re: [Emc-users] Probe

2015-12-13 Thread Dave Caroline
On a cmm the probe can be calibrated around a reference ball in
multiple directions to get the effective diameter of the stylus ball,
this should be done whenever the stylus is changed.

This can also calibrate out the variation in different directions
caused by the variation in contact force needed to break the contact,
some probes have a contact force adjustment at the rear which forces
the stylus downwards, while lightening the force reduces stylus
bending it also makes the electrical contact less good so is a
compromise.

More modern probes use a force sensor to get around the kinematic
design problem.

The one you are looking at looks like a good probe. If  you get it let

Agreed. The one that I linked to is $256 including the TTS holder which you
may not need. I'm unsure of the source of the $1200 reference.

At first, we had trouble with the Tormach economy probe. The contact can 
electrically bounce on the make or break motion. The slower the motion, 
the more chance of bouncing. This is not a huge problem on the make 
motion, but I found that retracting from the edge would sometimes cause 
enough bounce to trigger a probe triggered on non probe motion error. 
Rogge made a new probing g-code just for retracting which masks the 
trigger. I use it just long enough to retract then use normal motion.

Keeping the probe and retract speed up also helps. The accuracy doesn't 
suffer until the distance traveled between servo cycles gets bigger than 
the desired accuracy, or the encoder or step size, so slower probes 
often are not any better than moderate probe speeds.

Debouncing can prevent probe errors but the signal time delay hurts 
accuracy, so as far as I know, we don't debounce.

Centering is done with six screws that adjust the tilt between the 
housing and the arbor. Three push and three pull so there should be no 
slop between the housing and arbor.
http://www.tormach.com/uploads/474/TD10088_Passive_Probe_Install_0515A-pdf.html

There is a set of probing routines in the Tormach UI that automate 
common probing actions, including centering the probe tip. I have found 
that the centering is quite stable if one doesn't leave any push or pull 
screws loose when adjustment is done.

Tormach (and others) can provide (practice) ceramic probe styli that are 
stiff but break easily enough to protect the probe and work.

Re: [Emc-users] Probe

2015-12-13 Thread Ken Strauss
In the posts on CNCZONE to which I linked earlier the conclusion seems to be
that the force to actuate the Tormach probe actually bends the "stiff"
ceramic staff and causes significant measurement errors. Using a larger
diameter carbide staff seems to work much better.

Ruby probes direct from Renishaw are surprisingly inexpensive:

There are a lot of videos on Tormach probing on Youtube:

My probing posts may seem a little spammy, but there really is a lot of 
general probing information at the links that can apply to other products.

Most such time killers are generally written by whoever has the itch, 
Lloyd.  How long it takes is a function of the grid resolution you want, 
and to some extent the type of probe used.  The only one I wrote was to 
copy the faces of a rifle magazine floor plate for an old P17 of mine that 
I thought might be a little easier to carry afield if I made an alu floor 
plate, thereby lightening a 14 lb monster to 13 lbs 15 oz.  About a week 
into the project I balanced the books and the pieces are still in the shop 
drawer, in the white.  I could carry one less spare round and lighten the 
load about the same, for a P.O. Ackley-06.  Never needed more than 3 anyway 
 that time was because I needed a sighter shot at 640 yards.  I put the 
2nd and 3rd rounds through him about 2 apart.  He ate well.  Nice rack 
too, wish I still had it.  I still have the P17, but its due for the 2nd 
new barrel since then, 4000 rounds a barrel usually, but this one has some 
rust pits near the muzzle so its well on its way to another new Douglas 
now, but I'm about wore out too as I come up on 80yo this fall, so I'll 
likely let one of my boys worry about it.

 assembled.  I don't recall now if they have schmidt outputs or not.
   
Nice probe.
I made one using the Renishaw patent using three carbide pins resting on 
steel balls. If one of the pins is lifted, the circle is broken and the 
switch (de)activates. My webpage 
(http://www.myvoice.nl/freesmachine/nulsteller.php?lang=en) shows it 
being developed as a tool-length probe but mounting it upside down in 
the spindle makes it a touch probe - only needs a different bottom plate 
(becoming the top-plate with a pin to fit in the collet) and a probe tip 
instead of a flat probing surface.
The design is a bit complex but the nice thing is that it works great on 
curved surfaces as well.

Regards,

Rob
