Chinese 6040 stepper drives

[john swift]

Various Chinese 6040 manufactures use different electronic hardware
some use an all in one board others a variety of breakout boards and stepper drivers

photos of the electronic hardware in your machine will be helpful


If you have lost two” X axis stepper drivers”
inspect the cable connecting the X axis motor to your control box for damage
an intermittent break will damage the driver

a quick web search for the YOC335 didn't indicate if its built around the TB6560 or TB6600 IC
open the faulty driver and take a picture of the board

to complete the job you may find you can obtain a TB6600 based driver for example quicker than the original YOC335
one thing to check is the connectors : –
some have screw terminals for all connections others 2 and 4 pin connectors

what's power supply output voltage ?
