I just bought and fitted a Sprite extruder to my E3 Neo. I spent some time getting the steps right. I had to go down a bit from the 429.4 in the manual, but I'm happy with it now. z-offset is also good
My issue seems to be the X/Y nozzle offset. Everything is way off-center. I can tram the bed, but levelling is not starting from the center. I've tried the "Set Home Offsets" option in the menu, but I get the following message "MIN/MAX Too Far"
If I go into "Homing" and then "Home X" it moves the extruder all the way to the left and touches the limit switch. This leaves the nozzle about 10mm in the left edge of the build plate. Seems fine... The display shows the X position as -26.
"Home Y" moves the build plate back and touches the limit switch BUT the nozzle is now in front of the end of the bed and the CR Touch probe is even further away from the edge of the bed. The display now shows the Z position as -15.
Auto Home leaves the extruder way over to the right of the center of the bed.
Regarding the black cylinder in the pics: The nozzle would scrape along the print in the spots that look like heavy over-extrusion. There's a oval-ish area of over-extrusion on one side and the other side looks somewhat ok by comparison. The dimensional accuracy of the cylinder is off. The diameter is not consistent.
I did try measuring the X and Y travel by moving them 100mm and then physically measuring the travel and both measured 100mm
How do I fix this?
