I'm at my other home in FL currently and crashed the head on the printer, destroying part of the head and splitting my ceramic bed. Nema23 and 9mm belts may have been a bad choice.
Tried updating to use the new pythonic configs and it turns out in the current fdm module (without using the subdirectory to override it like in the Rostock config I borrowed from machinekoder) the delta_r or rod length is ignored. So 0,0,0 was below the bed. I slowly approached it, but the interface didn't register my stop command until it was too late... so I got to watch it slowly destroy my bed. :)
My fault for removing the physical estop button for aesthetic reasons..
Prime is screwy due to Irma so parts wouldn't get here in time for me to fabricate them, and I can't find a suitable polished ceramic tile locally.
So... I'm not going.
