Title: Z Axis Creeping after Feed Hold
Post by: geh7552 on March 11, 2013, 12:16:35 PM
Pressing "Feed Hold" and jogging away to clear chips, I press the "Cycle Start" to resume and noticed the Z axis starts creeping (0.001" every 2 or 3 seconds) back to home position. No issues with the X or Y axis. I've duplicated this issue several times to verify. As long as I don't use Feed Hold everything works ok. Using Gerry's 2010 screenset, licensed V.066, Gecko 540 driver.  Any suggestions?

What are you using to jog with?  I had a similar problem with a bad Xbox controller.

Using the PC keyboard. The problem on happens after a feed hold command. Did a search on this forum and there are several threads with feed hold problems that resulted positioning problems. Seems to be a bug in Mach 3.

Hood, Do a forum search on "Feed Hold" and you will find several threads. Using a X axis sufacing wizard written by Kirk that is included with Mach 3. The gcode looks ok.  As I said... as long as the Feed Hold command isn't used it runs ok.
