General Mach Discussion / Jog Z Slow while X & Z Fast

« on: March 27, 2015, 10:49:09 AM »

Hi All,  new to cnc mach 3   is there any way to jog the z axis .002 or .003 without using the jog speed down to 10%.  I want the other axis to move faster.   now each touch on the keypad moves the z .017 which is too much for some milling parts I have to do.   Also, I seem to be getting some noise between the components.  can the gecko 540 box run everything okay if sitting beside the PC or is there some separation needed?  I relocated the inverter and am now using a shielded cable to the spindle which helped some but there is an occasional jump from the mach 3 when milling parts.  This happens once or twice a week and has ruined several parts.   I also have a wireless mouse beside the g540 which I was told would be ok.
  Thanks,  adjaguar

General Mach Discussion / Interference from cabling?

« on: March 27, 2015, 10:40:13 AM »

Hi  new here to Mach3 .  I have a cnc router and every now and then, the part is ruined because of an unplanned move while routing, especially aluminum.
Could this be interference from cabling?   I have the inverter separated from the g540 / computer and that helped some, but still have the jumping problem.  Also, is there any way to jog the z axis by .002 or .003 at a time without moving the job tab down to 10 %?  Thanks  adjaguar
