Morning all, managed to get it up and running and wondering if anyone can give me some electrical advice,

I'm currently using an akz250 (usb Bob) no I know that u need a stable 5v to run? Also using dq860ma steeper drivers.

The problem is when I run a long program like the one in the picture, I loose steps in the x axis, one roughing cut depth is different to the next.

Now I've tried slowing the motors down and changing the acc, and the problem still happens.

I had a quick look at my wiring and ran a multi meter over the terminals, I have 4.45v going to (can't remember if it was step/dir) and 2.7v on the other terminal,

Also my drive has an enbl + / - terminal, do I need to wire 5v signal to this? As my drive is working without it?

Thanks
