UMO-X Axis only moving one direction.

Recommended Posts

Hey guys,

I have recently started getting my printer up and running after having to put it away for a while and I have encountered a bit of a problem. My x axis only moves to the left. It is super weird and I can't seem to figure out why it is doing it. When it came out of storage the heatsink on the Stepper Driver had been broken off so it is no use so I have been swapping the driver from the extruder just to test it.

To try and resolve the issue so far I have:

-Tightened all of the belts

-Lightly sanded the X rod and lubricated it

-Tested the endstops (Using ulticontroller to confirm they work)

-Swapped the stepper driver to both the one from the extruder and the one from the Z axis

-Plugged the X motor into Y (Functions correctly)

-Plugged the Y motor into X (Same unidirectional issue)

-Re-installed the Marlin firmware through Cura

-Removed the electronics from unterneath the printer and inspected both the shield and the Arduino itself (Both fine)

-Reset the Arduino

-Installed the test sketch to the arduino, everything that should be working is functioning correctly.

-Re-installed the electronics back into the ultimaker and ran the test (Once again, worked perfectly)

-Reset Arduino again before installing Marlin (Issue Returned both when using "Move axis" on the ulticontroller and trying to run a print)

Ok so any idea why this is happening? It seems to me like a software bug rather than hardware but it seems unlikely seeing as it worked for so long before the issue manifested.

Thanks for the help guys,

Jackson

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
