stepper drivers and UMO mainboard

Recommended Posts

Hi

I was about to install a Bondtech extruder to my UMO and got some problems.

After removing the orginal extruder, unplugging the cable and plug in the cable for the Bondtech extruder, the extruder motor didnt run.

To check if the machine was atleast working, I replugged the orginal extruder and that didnt run either....(machine was working fine before I started)

So I figured maybe the stepper driver (silentstepstick) was not working, so I exchanged the extruder chip with the X axis chip, but forgot to check pins, so I placed the chip the wrong way, and now it seems nothing works :)

Even the Ulticontroller doesnt lit up.....so Im wondering if its enough to replace the silentstep sticks or have something been damaged to the mainboard ?

Edit

If I remove the stepper driver on extruder and X axis, the ulticontroller works again....

When you put those stepper  drivers in backwards it destroys them, I've proved it more than once;). So you probably have 2 crook ones now.

 

Yeah, I found that out....i took the old stepper drivers and put on, and got the servo noise back, but now everything work again :)
