Re: Push Wheel Temperature Mod

I looked at the push wheel datasheet, and it seems like the output is in bcd.
Can someone please explain in a little more detail how the resistors are connected to the bcd output to produce the correct series resistance?

Re: [BUG REPORT] Uneven vertical prints

Thanks for your suggestions everyone. I switched the z and x motors - here are some photos of resulting prints. DSC_8105_50.jpg DSC_8107_40.jpg The distortion is still there, but it now resembles a saw-tooth pattern, rather then a sine wave. It is also now quite clear to see that the entire layer is...

Re: [BUG REPORT] Uneven vertical prints

Thanks Peter I've looked at the motor shafts on all axes. Given their short length, It's difficult to tell if there's any deflection, but they all seem straight, and 90 degrees to the motor face / mounting. The pattern seems to repeat between the amplitude peaks. 8 layers, then 6, then 8, then 6 ( o...

Re: [BUG REPORT] Uneven vertical prints

Thanks Steve,
I'll look into the motor shafts.

I've previously looked at the guide rods, and they all seem straight enough to me.

Re: [BUG REPORT] Uneven vertical prints

Thanks Steve, but my mini doesn't have any lead screws - it's all pulley driven.
As far as I can tell, the guide rods all seem pretty straight as well.

[BUG REPORT] Uneven vertical prints

My Up! Mini is printing misaligned vertical walls. As you can see, the distortions are repeated every 9 or so layers ( about 2mm ). The problem gets worse when printing further away from the center. Each of the below was printed at 0.20mm layers, on fine resolution. Links to the STL's printed: Batte...
