HIYA Ian , Come on over I have a spare room here. The neighbors are already used to a smartA## redneck so you will fit in nicely. You will probably have to get a decent tan thought (;-)

So far the Protected move mode is working here. Probably NOT going to see it in Mach4 either. They looked at me like a crazy man when I asked for it so YOUR Solution could be a blessing to probers.

I had also asked for a solution for missed hits to create an error  and signalling the OP to a problem.  This would be a BIG help as I see it.  MOST problems in probing is missed trips creating BAD data.  A lot of the people I have helped with 3d probing could use it. It is HARD on them when I point out the proble with their point cloud is all the MISSED trips in the point cloud.  After LONG 12hr probing runs they tend to get pissed that the cloud is trash and unusable for the most part and have to start over.

ANY solutions for a missed trip notification ???  AND a error trapping code in the Program does not help as MOST of my/our routines are GCODE based (very dependable) and there is no IF in that code and no access to Systems #vars to compare to.

Just a thought,(;-) TP

Tan I can do - just as long as I don't have to wear your gimp suit is all...

Moving on - trying to get that out of my head...

Could a few of you guys give me an idea of your steps per (please state imperial or metric) ... ta.

6 mm pitch ball screw (actually 1/4")
512 line encoder (so 2048 edges)
so ~328 edges per mm

50,000 per .200" Yaskawa AC Servo at worst case

You should see his bowling shirt collection.

Sorry - should've been clearer - steps per from motor tuning for each axis X,Y and Z.

160 steps per mm for all axes (20mm lead, 200 steps per turn, 16 micro-steps per step), I was running it at 4 and 8 micro-steps before.

10,000 steps per inch x and y, 60,000 steps per inch on the Z.  :-[ Like a few other tools I have.............. it isn't much but it makes me happy!  ;D
;D If you could see the things I have in my head, you would be laughing too. ;D

My guard dog is not what you need to worry about!

But then to a modern man like yourself - it's not supposed to be just about you Brett  ;D

Any road up... Probe info... trip angle and max deflection angle. I know linear movement depends on length of stylii in use - but just to keep it simpler for the moment - what sort of linear measurements are we talking about between a good trip and crunch point? Just trying to get an idea of the range of your different probes.

Based on my touch-probes, which I made myself:

ZTO: can handle ~1 mm overshoot in Z axis for clean reset.

3D touch-probe, with 20 mm tip: sphere of overshoot about 1 mm, for clean reset.

Further overtravel to 2 mm is possible in each one, but  would need to check that they had reseated properly.

Cheers
