Hello I just received my import machine this weekend, after some tinkering I was able to get things dialed and and calibrated fairly well.
My issue currently is ; if I move the machine by keyboard it moves very smooth, up to 1000ipm I’ve tested. But if I load g code and start it ( even at 700 ipm ) it makes a horrible banging noise as it moves. I cannot tell what’s going on, but I do know the servos are very aggressive when they stop, always makes a loud thud.
Could the servos be starting/stopping very rapidly for some reason?
I know my drives are rated for 75v and they have 75-78v running to them.
It’s an acctek 1325
Lead shine servo drivers and easy servo motors
Mach 3
Mk3-et Ethernet controller wihyx I believe.
Helical rack and pinion drive.
Ball screw z axis.
I’ll attach some short clips

It’s a lot louder then it sounds, almost shakes my floor.
