Summary

Parts to mount a dial indicator to the UM2 head for precise leveling

Using a feeler gauge isn't super great for leveling. Using a dial indicator is the best method so I made a mount for my cheap eBay 10mm x 0.01mm indicator. It mounts on the front right print head screw and is very effective for bed leveling. Its designed in such a way that it just does not hit the printer during the levelling process but lift the probe as it moves.

Simple yet incredibly useful

Drill out holes for best fitment

I drilled out the holes after printing for good fitment. 8mm for the dial indicator shank, 6mm for UM2 print head screw and 5mm for the probe connection

Can you explain in a little bit more detail how you level the bed with the dial indicator? What steps are needed?

Sorry! Its fairly simple:

1) Mount the dial indicator on long head of the the front left hotend bolt
2) Quickly skip over the "rough adjustment step"
3) For all 3 points on the second step, raise the build plate until the point where the dial indicator just stops moving. Don't forget about the unmentioned fine adjust nut on the Z axis!
3.5) Optional: Zero out the dial
4) At this point the nozzle is just touching the head. Wind the screw to lower the bed by whatever amount you want to use. 0.10-0.15mm but your build surface will vary this step
5) Accept and raise the needle while the head jogs to the next point
6) Repeat 3-5 for all 3 points

Bam! Leveled.
