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 
it and see if it will come out.

Yes, I thought about building a receiver out of various 
parts, but there are application specific parts that combine 
all this in one unit.  Most are made with 38 KHz band pass 
filters for VCR remote controls, but the QSE159 does not 
have the BPF, looked to be sensitive enough, and was really 
cheap ($1.06)

I used a bank of 6 LTE-4208 IR LEDs to send the turn on/off 
burst to the device, powered by a 2N, and that works 
great from more than 6", which is all the distance I need.  
The QSE159 only needs a pull-up resistor, and it works great 
to receive the IR data from the probe.  So, that end is all 
working.  I need to make up a little adapter to connect to 
my CNC interface and put it in a box, and I am ready to 
start testing probe routines.

The 5i25 is completely flexible, more so than a standard parallel port,
as every pin from 1-17 can be input or output.  If none of the standard
bitfiles covers your pinout need, Peter Wallace or John Thornton can
easily generate one for you that does.  It isn't at all impossible to set up
to generate your own bitfiles, but requires careful editing of some vhdl
text files.

Re: [Emc-users] Need unlocked copy of a pdf for a breakout

[Gregg Eshelman]

I designed a 3D printed case for it, with a solid lid and one with slots so the 
screw terminals can be turned with the lid on. The solid lid would be for a 
permanent install where you don't want easy access for people to fiddle with 
it. Mounting tabs would be easy to add with any 3D software that can import and 
export STL files.

That is definitely NOT the mach3 pin out. In fact I dont think it can 
work with mach3. it uses some of the higher pin numbers as step control 
pins, and I think mach3 only supports pins 2-9 for the step signals, the 
others can be used for output signals, like spindle control.

It does look link a nice board- I like having screw terminals and header 
pins for connections, it gives better choices.

I think that they start at about £25. And there are always many on eBay.

34 outputs. Don't forget the second port header.

I am just setting up a $4000 Blum TC50 probe that I was 
incredibly lucky to snag on eBay.
I'm going to hook up a watchdog to stop motion when the IR 
signal from the probe is not being received.
Well, we will see how long it takes me to have my first 
accident. Hope it will be a while.  It does look like it is 
very robust, so that the stylus will snap before the probe 
unit would be harmed. The stylus will only cost $75 or so.

I don't know if they come with any documentation.  Mine never have.

Just google for "5i25man" and you will find the manual. This works for
any Mesa card.

I think so.

Two sources exist. One is hosted by LinuxCNC:
http://git.linuxcnc.org/gitweb?p=hostmot2-firmware.git;a=summary

The other can be found in the support-software link on the Mesa web site:

Hi Jon,

Regarding the receiver I have not built anything yet, but when I was

Re: [Emc-users] Need unlocked copy of a pdf for a breakout board I just bought two of.

[dannym]

Why the 5i25?

I have the 7i92, I like the ethernet.  It allows me to put the card in the 
control box without a mass of critical cabling between the PC and the drives.  
Ethernet doesn't have much for length limitations.

Indeed.  And for that reason alone I would buy the Mesa FPGA cards, even if

[Ralph Stirling]

Yes, Mesa has been kind enough to open-source all the vhdl for their cards.
I learned vhdl from reading Peter's excellent logic.  You can look all the
documentation up on Mesa's site and in the LinuxCNC source tree.  You
have to install the Xilinx webpack, but you don't have to use the Xilinx gui
if you don't want to, as the LinuxCNC/Mesa setup has makefiles for compiling
the bitfiles.  I have successfully customized Mesa's logic for the 7i43 for
specific needs, and I have used what I learned from their vhdl functions to
create logic for both Digilent fpga boards and our own custom hardware.
The Machinekit fork of LinuxCNC has the fpga logic running on ARM/FPGA
boards.

Mesa has made a tremendous contribution to the community with their
hardware and firmware.

Thanks Dave.


I similarly dislike optos.  I have doubts that any properly made drive
can even produce dangerous "spikes".   They seem pointless.


My understanding is that the optos are there to protect the driver 
inputs and sometimes do signal voltage conversion. The cable from the 
controller to the driver can be long and travel close to noise sources. 
This makes the cable susceptible to induced voltages which can push the 
signal too high or even negative, which will blow out the input if not 
protected.


Aside from noise, usually the output at the controller has a current 
limiting resistor for protecting the signal driver. These drivers are 
usually higher current devices (maybe 24ma) so the limit resistor is 
sized for the higher current. On the other end, the limit resistor is 
there to protect the opto's LED which can take less current (about 10ma 
is common). The LED is a current device so signal voltage is secondary 
the resistor just needs to be sized appropriately.


Induced noise voltage can get quite high so sometimes a Zener diode is 
used to clamp the input at a max. voltage to ground. LED's have very low 
reverse breakdown voltages, so it is common to put a regular diode with 
a high breakdown voltage in series to protect the opto when the noise 
pushes the input negative. This diode will have a forward voltage drop 
that will need to be considered when sizing the limit resistor.


Optos used to be slow, but there are modern optos that are very fast. 
One just needs to look at the datasheets.


I attached a very rough schematic of what might need to be on an opto input.



I work with a 7i92 card which is ethernet, and thus already offers
galvanic isolation through the ethernet.  If there were a huge surge, it
wouldn't propagate back to the PC.  The PC ain't a high-dollar item anyways.
The AM882 drives all have differential opto inputs/outputs themselves,
there's no case for even hypothetical "spikes".

[Ralph Stirling]

The 5i25 is completely flexible, more so than a standard parallel port,
as every pin from 1-17 can be input or output.  If none of the standard
bitfiles covers your pinout need, Peter Wallace or John Thornton can
easily generate one for you that does.  It isn't at all impossible to set up
to generate your own bitfiles, but requires careful editing of some vhdl
text files.

I crossed them of the list some time ago. The pin-out is 'silly' with
14, 16 and 17 mixed into the S/D list and then 9 used for the spindle.
Yes it needs software like Mach3 which can remap the pins, but the
killer is the hand control only being a direct feed to the stepper
motors. Has its uses as a manual controller but one would expect a
pendent to run the software?

The 5I25 should be able to support that breakout easily if you can actually 
determine the parallel port pinout. Unlike even a parallel port, the 5I25 can 
support completely arbitrary pinouts (any pin can be input or output) as long 
as the ground pins dont move, the pinout is possible

Re: [Emc-users] "Probe triggered during jog"

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.

That is definitely NOT the mach3 pin out. In fact I dont think it can 
work with mach3. it uses some of the higher pin numbers as step control 
pins, and I think mach3 only supports pins 2-9 for the step signals, the 
others can be used for output signals, like spindle control.

It does look link a nice board- I like having screw terminals and header 
pins for connections, it gives better choices.

Gene;

See the attached pdf I made.


This is the pinouts as I read them from the ebay display images. It doesn't 
answer everything and I think you will want to use the B axis for spindle 
control since this BoB only provides for On/Off but no direction. Another 
oddity if I read things correctly is that the A axis had a limit input but 
nothing for the B axis (which is partly why I would use B for spindle control.)

I am sending this direct to you since I believe the PDF will get stripped off 
on the list.

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
