My x-axis motor is not working and I checked the motor wire with a continuity tester and it was all good. Could it be the motor driver that is causing the issue? Also a phone number or email for QiDi tech support would be great.

I’m having a similar problem, x-axis isn’t moving properly and making a grinding noise. I contacted Qidi support, they are sending a new cable (to replace the original cable which did work for about a week, then the x-axis issue hit me and used the extra cable they included to fix that but only lasted about 2 days before the issue came back). They are shipping a new cable, that they indicate will fix the issue once and for all. It should arrive in the next day or two. Apparently, there was a problem with the cables they shipped in several printers and they quickly found the issue and are replacing them at no charge. So, give them an e-mail from the info. below and they should have a replacement out to you quickly (via DHL/ 3-5 days).

You can contact them via…

A continuity check will most likely not be reliable. I had a cable go out that checked fine but wouldn’t work. Once replace everything was back to normal.

It’s not the motor wire but the limit sensor cable. Try replacing those. You should have a spare that came with it.

While waiting for support, testing the driver is pretty easy. With the power OFF, swap the stepper driver between the X and Y axes. If the Y axis now fails, then the driver is bad. It *could* also be the control board, but the driver is more likely to be the culprit. They are pretty finicky, and anything can fry them - setting vref on the pots with a non-ceramic screwdriver, playing with stepper driver wires while the machine is still powered on, etc.

Hope this helps!

I just send them an email and thank you for the response.

Very welcome, please let me know how it goes.
