Main Board

Post by Hetro » Sat Apr 08, 2017 12:49 am

Hi, I have a new printer and the "Y" axis will not work, if I plug the motor into the x axis the motor works. Anyone have any ideas, I would presume would replace the control board.
Thanks,

Jeff

Swap the driver boards between the x and y axis to see if the driver is bad. I had a bad driver with my kit.

Yeah I swapped the cables around and the motor works, is that what you mean by driver failure.

Let me run this by you again.
If you swapped the cables to the Y axis (that wasn't working) with the X-axis (that was working) and now the Y axis works and the X-axis doesn't work then you've debugged that your motors are good. Now you have to check if the cable or the driver is bad.

Physically swap the two driver boards for the X and Y axis with each other.... mark them with a magic market so you know which one was the Y and the X axis driver originally. Assuming you are back to the Y not working and X working, swap the two drivers (these are the red modules that are plugged into the controller card). If after you swap the drivers the Y is now working and X isn't then you have a bad driver. If the Y still doesn't work after swapping the drivers then you have a bad cable. My assumption is you have a bad driver board. Geeetech is very slow getting replacement parts to you, I waited 5 weeks for mine.... I purchased a set of 4 locally off of ebay for $6US and had them in two days. You should purchase a few to have around, although the drive chip is very hardy and can stand up to quite a bit of abuse. The biggest issue with the driver design is the thru hole 0.025 square posts protrude high enough through the PCB to cause interference with the aluminum heat sink on the driver. If you short of one of the pins by letting these pins touch the heat sink you risk damaging the controller card and / or the driver board. When attaching the thermal heat sink sticky pad to the back side of the aluminum heat sink make sure it's large enough to cover the entire heat sink underside.
