So I have put together the Wilson 2 kit and have the bed levelled, motor currents set, and I upgraded to Marlin 1.1.8 and patched a few files to support the PICA and the rack and pinion setup, and my first layer looks pretty good.
I seem to be having two specific issues right now:
- when heating the bed up beyond 72 C causes a heater fault and freeze
- when I was printing a single cube (20x20) near the end of the print it had a thermal runaway, yet the temperatures shown in s3d were less than 3 degrees from what the hot end should be and the bed seemed to be fine.
- there appear to be some lines on the print where every 4 or 5 layers you can notice it, especially on corners
I am a little suspicious of the arduino that came with this thing, I was thinking about trying to switch it out for an “official” one I have lying around.
I definitely have upgrade plans for this machine, but I wanted the stock kit to be working well first.
The slicer is simplify3d, and it is running through the usb cable.
EDIT: The ribbing seems to be about 0.5mm in pitch, which is exactly 1/4 of the leadscrew’s 2mm (effective is 8mm because of 4 start).
My configuration if anyone interested: https://gist.github.com/madebyjeffrey/87bf7d4801897b81f29a28b02921a402
