My prints lean forward!
Anyone else ever run into this?
Someone at UM said to check the Y motor pulley, the set screw could be loose
Thankfully it's easy enough to get to...unscrew motor and untangle from belt.
I just HOPE that's the fix.

Mark the pulley/shaft. Print something very fast. Then check the marks to see the culprit.

Ah good pro tip...see if we have some slippage
I'll be curious if the set screw is loose at all. How tight should the belt me? I can move it about a half inch so it isn't super tight

Re: My prints lean forward!
It looks to me as well as pulley slippage...

Re: My prints lean forward!
Well I found the pulley to be perfectly fine...the belt could be tighter...so I pushed down on the stepper as far down as it'll go and the belt feels tighter. Test print under way!

Re: My prints lean forward!
Test print came out great...so it looks like the belt was too loose. I really cranked hard on the pulley/set screw and it moved slightly...so hard to say if that did much
Putting the stand offs back in on the far side of the motor wasn't much fun, I think the UMO+ uses something different

Well replaced the motor pulley with a 2-set-screw version
Maybe the other pulley, attached to the rod, needs a major twisting

Re: My prints lean forward!
I've used an allen wrench to tighten every Y axis pulley. They all took some tightening but none were obviously loose.
I also tightened the belt again
Doing a test print now

Re: My prints lean forward!
Well no more leaning
But wow. So many blobs
235c with low fan and 45 mm/sec
nGen filament. Yikes. Looks awful

Re: My prints lean forward!
Now wait...when I thought about replacing it, the opinion was to leave it alone?
And keep in mind this is nGen, not PLA, so my thought was bad settings for the filament
Now I still have a bag of print head parts from the dual extruder option. Or..should I be using a newer version to replace it?

Re: My prints lean forward!
Get the spare one, test all works. And if you ever install the dual, buy one.

Re: My prints lean forward!
Ok, I'll have to dig up the manual to properly dismantle and install it
