Axis Hangup!

Hello...

Here is code that hangup Axis.


Seems that axis dryrun that code and make infiniti loop as #5070 parameter is not updated (probe trigered)
How to overcome that?

Why do you need while loop here?

The idea of code is to make move until probe hit object.

As position is not known I just make progres until get hit.

If I want just one move then move should span trought entire table. But If the probe is in midle of table I got soft limit error.

You can use G90 and an end position before the limit point.

Where to read axis limit?!? And current position?!?

www.linuxcnc.org/docs/devel/html/gcode_m...38.2:-Straight-Probe
You can read the current position after the probing from #5061 ... #5069
You can get the probing result from #5070
The axis limits are in your INI file

Here are misunderstanding I think...
I Know that axis limits are in INI. I wrote that. But how to read that value inside Gcode?
I know that #5061 to #5070 are probe variable.
But how to determine current position (before probe move?)
So let's go trought example.

I jog machine inside some hole. Now I want to find center of that hole.

1. Remember current coordinate (how to do that?)
2. Go slow Y+ from current position until probe hit or soft limit reached (remember position #5061.....)
3. Go rapid to coordinate from step 1 (back to start)
4. Go slow Y- (same as step 2)
5. calculate midpoint from step 2 and 4 and go rapid here

6. do same thing for X axis (this is precise)
7. repeat again for Y axis (now Y is precise too)

show message that's done and show diameter too...


Holecenter program's I found all require to tell hole diameter and position. I'm shure that's not necessary. Just don't know how to deal it.

I know, this is an old post, but...
1rst movement-
G38.3 Z0.001 and:
# 5061; #5062; #5063...become populated at the current position without error message, or: # 5420-5428 - current position including offsets (X Y Z A B C U V W).
