CORE One Bed Level Calibration Shims & Dust Cover 0.1 mm REMIX

The CORE One's bed can be tilted relative to the CoreXY kinematic's plane by a surprisingly high amount (up to about 1 mm height difference between edges). While this is compensated to some degree by the printer's automated bed level correction, some skew between the Z axis and the X and Y axes will remain. 

This model helps compensate for this skew by leveling the CORE One's bed when it slams down into the bottom during Z calibration. It also protects against dust and debris entering into the lead screw holes.

Leveling procedure

As per the in the original instructions:

• Control → Calibration and Tests → run Z alignment calibration 
• Control → Auto home the printer 
• Move Axes → Set Z height to 0mm (or to 1 mm if you have a feeler gauge or other object of precisely defined height - see here for a printable feeler gauge)
• Control → Turn off stepper motors 
• Move the head around the bed and see if there is a lower corner (mostly it is the left front). Make sure not to scratch your build plate with the nozzle moving around.
• Measure/estimate how much the bed is lower 
• Print the model with the measured/estimated correction 
• Place it onto the stepper mount where the correction is needed
• repeat until satisfied

Recommendend material

PCCF is recommended, PETG seems to work fine as well.

Recommended print settings

To achieve 0.1 mm layer height, I started with the 0.15 mm Structural profile in PrusaSlicer and decreased the layer height to 0.1mm. For the first layer I set 0.2 mm layer height to improve bed adhesion. So:

• 0.1 mm layer height
• 3 Perimeters
• 10 Bottom and Top layers
• 25 % Grid or Gyroid infill
