Problem- Z-axis losing steps or not getting enough power?

[Realmseeker]

Good day,

I have been testing out all my gear and about to get ready to make my first cuts. I am running a Gecko G540 on a meanwell 48V PSU. I am using Mach3.

I was trying to use the wizard in Mach 3 that does the rectangle bolt pattern and drill a grid. I had the spindle(a laminate trimmer) turned off and was just running the program to see if it would work.

I was doing a 5x5 grid with a hole every inch. .5" deep hole with a peck of .3.

As I ran the program by the 4th or 5th hole I would see the DRO for the Z-axis moving but it would be party way along till the axis actually moved. It was like a long pause or something. Also the motor sounded like it was sort of losing power or not getting enough by the 4th hole.

Am I just over working them too much? Would a slower feed rate be better? I have the motors tuned down fairly low. Other times I try to Zero the machine, and Mach shows the z-axis DRO moving but the axis isn't. But if I jog the axis it works, just not when I use the ref all home button. I turn off the power and reboot Mach and all tends to be fine.

I am also not using shielded cables, is this a problem with interference?


Thanks as always.

Could be you need to mid band tune the G540 When I set up my JGRO I was getting btte than 120ipm But whn it came time to actually machine stuff, I had to slow it down to 60ipm rapids, and 45ipm cut

I thought the G540 came with a built in filter for that? Do I tune it out by turning the 'trim' screw? Or should I just slow down or speed up?
