3040Z-DQ CNC - X and Y Axis Motor/Screw Blocking/Skipping + Rough Noise

[Dominic-ASP]

I just bought a Chinese 3040Z-DQ 230W Four Axis Ball Screw CNC and followed the instruction from the manual to configure the machine with Mach3.
I started testing the machine with simple X Y Z commands using Mach3 and my keyboard and noticed some really rough noise and experienced motor blocking/skipping at random locations on the X and Y axis. I did not experience anything wrong in the Z axis. There is definitely something wrong with the machine and/or configuration and I'm trying to get your advice on how to fix this and if any of you ever experienced similar problems.

To get a better idea on what I'm referring to, please watch my video and notice the problems encountered at 0:03, 0:11, 0:19.


Thanks for your help!

Hi Dominic,

Same issue here with a x6 1500gt usb from caving cnc website.

Did you get the chance to solve your issue ?

I also opened a thread and will keep you posted if you did not already solve your problem

Cheers,

Just to be sure to have have understood your statement.

You threw away the motor connectors and soldered the wires directly to the cables and that's all ?

really rough noise and experienced motor blocking/skipping at random locations on the X and Y axis.

Did you solve the issue already?

I have the same problem on X. Tried the electrical stuff first and had some improvement. But the issue does not go away completely. So I took a look at the mechanical stuff: When turned by hand, the ball screw tend to block at random locations. Any idea what causes that? Can it be fixed?
