Title: Mach V.043 feed hold still broken
Post by: Sage on March 14, 2009, 10:45:23 AM

I just happend to try "feed hold" and upon restart, the program took off to places unknown. It was inside a subroutine at the time, if that matters. Just thought I'd report this problem again. Seems it's been around quite a while. It would be nice to be able to pause a program for a lot of reasons. Not sure if it was supposed to have been corrected.
 If a code example demonstrating the problem is required, let me know.

Sage, post your code and a note of what line it is on when you see the problem. Give us enough information so we can recreate the problem.

Use the attached code. Zero X,Y,Z axis as requested at the start and press start again.
The program starts milling at around the 2-o'clock position.
Let it go around once and press the feed hold any time after it passes the start position.
For me it continues along the arc to about 1-o'clock and then buggers off staight instead of following the tip of the lobe.

I have the same problem with my Mach3 in my plasma table :S

Sage just a suggestion but it is never a good idea to MOVE the machine once MAch3 has loaded the Gcode. Mach3 is a buffered system and loads the buffer on program load. WHEN you change the coords after the load strange things can happen in weird places.

ALSO is the machine cutting this error or just drawing it on the screen?  I have seen many times that MACH3 draws in error but cuts exactly.

Just a thought, (;-) TP
