I have used the program from the manual to do this:
X-4. Y-4. Z-4. G1 F150. M49,M91.
X4.Y4.Z4.
M99P1
I've searched the forum but cannot find any specific answers to the following questions:
1. Does the F150 (IPM) need to be changed to F3810 (i.e. 150x25.4 to get mm/min in my case) to read the correct following error of 302?
2. Does it matter if I change the XYZ travels to larger figures as a move of 4MM (as opposed to 4 inches) doesn't seem to allow the travel to settle down to see an accurate following error for adjustment
3. Is it better to adjust using following error or voltage at the sig2 plug (.735VDC) and if so where is the sig2 plug and its common, is it accessible from the square white cannon plug under the 1010 card rack, i.e. the tacho wires coming in? Or the plug at the bottom of the 1010 card in which case where is the common?
4. If I run the prog one axis at a time I get higher following errors on the individual axis. Is it therefore necessary to always run all three axis' together when adjusting/balancing an amp?
Thanks for all the good advice. As I said, I searched but couldn't find anything on the above with reference to a metric adjustment.
Cheers,
Trebol.
