Hi, Sorry, I didn't explain myself very well - I guess I was just too frustrated at the time...... The EMC2/AXIS version I am running is 2.2.6 When I start up EMC2 I HOME each axis including A. The command I listed was indeed a typo - I missed one command out. what I actually feed into MDI, one line at a time is.. G53 G0 X0Y0Z0A0 G92.1 G54 G10 L2 P1 X0Y0Z0A0 G49 I just an a test and noted all the actual values - here is what I got. At startup A read -715.410 in AXIS. I hit the HOME button and the display didn't change. I issued the G53 ....... command and again there was no change. On issuing the G92.1 command the A value changed to -16458.876 G54 produced no change The G10 ..... command zeroed all the axes including the A axis. Now I jogged the A axis to 68.023 (arbitrary angle) and hit the TOUCH OFF button and pressed ENTER with 0.00 in the box. The A axis value changed to -1659.772 I then jogged the A axis to -1300.002 and again hit the TOUCH OFF button, again attempting to set it to zero - the A value displayed changed to -10438.157. Now I again hit the HOME button and the A value changed to -10865.950. My machine setup is very basic - no Limits, Home switches etc., just 4 steppers. The figures don't make any sense to me and, as I said, it seems the only way I can zero the A axis is using a G92 A0 command....... -- Best wishes, Ian ____________ Ian W.
