@damaged_goods sounds to me like replacing the pin wasn't successful in fixing the BLTouch, so it's probably time to buy a replacement. There's not much you can do on the Duet side if the probe itself is broken!
@damaged_goods You could perhaps trigger a homing move when Z changes, using daemon.g, (assuming you don't use Z lift on travel moves), but a better way to do it is to add a homing move in the layer change Gcode in the slicer. Most slicers can do this nowadays.
The photo isn’t quite clear, but I tend to assume the gap might be where the layer changes are located. If that’s true, observe your printhead when the layer change occurs: what you call a "gap" rather looks to me like an imprint of the nozzle tip into the first layer infill. This deduction is far fetched, to drill down on this, you should eventually reduce print speed.
@dc42 stand alone. My file uploads went from taking several minutes to being instantaneous. Huge difference in speed. It remains to be seen how this will influence prints but I am enthused by this change.
@damaged_goods There's a few options of 'basting spray for quilting' on Amazon, but I can't find any info on what adhesive is actually being used. If you have a can, please can you show the ingredients on the back? Also, what filament types have you found it works for; PLA, PETG, ABS, ASA... etc?
@Phaedrux Thank you for your assistance. I really appreciate it!
I did not include an expansion board M122 because I don't believe I have one.
Thank you again. Hopefully I won't be bothering you any time soon.
@T3P3Tony Thanks Tony. I think after it lays down the perimeter of the second bottom layer I will just pull the filament. After it's done the remainder of the 2nd layer without filament I'll start with filament again for the 3rd. That at the very least will save me about a 1/2 kg of filament.
