Front bolt torque
The most common mechanical issue is over-tightening the 4 bolts that hold the Y-axis in the front
bracket. This warps the Y-axis linear guides and causes the bed to move in a non-planar fashion.
To solve this issue, follow these steps:
1) Unscrew the 4 bolts in the front bracket until they are loose (not creating any pressure
against the bracket)
2) Jiggle the bracket in both directions so the linear guides have a chance to settle in a new
position.
3) Retighten the bolts without any pressure, so you can turn them by hand
Test result:
After loosening the front bolts, the test Gcode
shows that the top-left and the bottom-right
corners have been fixed and have proper adhesion.
The center square still seems to be too high, so
further tweaks are necessary.
