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.

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.

Maybe less than that. Is it Renishaw style?
http://www.renishaw.com/shop/stylihome.aspx

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

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.

your using Cheap Probes John ?
last one i bought cost me $3,500
after some idiot did exactly that .

i added some extra logic and a external keyswitch , to stop it happening

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

[Danny Miller]

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"

[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.

Danny
