The IR homing method is not very satisfactory as it is affected greatly by ambient light. You know you have to calibrate it before trying the homing command? I have given up using automatic Z homing, and do it (and the bed levelling) by hand before every print. Besides the ambient light issue, I print on solvent-coated glass rather than tape, and so it is not as easy to fix white tape to 4 places on the bed.Quote

Now it seems that on running G28 Z0 the printer homes and then crashes straight into the bed however its just past midnight here so going to get to bed and will continue tomorrow.

Yes, the ultrasonic method sounds extremely promising. I was planning to try the modulated IR somewhen, but I'll wait to see how the ultrasonic method works out. There are several mods I want to make on my Omerod, and my priority is with mods that improve the print quality, reliability, ruggedness or speed. Automatic Z homing merely makes it a bit more convenient, so is not at the top of the list. What I really should do is get another machine and do all the mods on that from scratch so I can keep this one printing - it's very addictive! One objective is to get the machine to a state where I am comfortable with leaving it unattended so that it can be left to print a large job overnight. That will need the addition of a few safety cutouts.Quote

I also print on glass coated with solvent cement, but I leave white PVC tape in the corners. It wouldn't work for a maximal-size print though Homing is fairly reliable using a modulated IR sensor, but I'm now trying out ultrasonic sensing, because that would work anywhere on the bed without any tape.
