Thanks to you both ! It is awesome to find such great support in this forum ! I cant tell you how happy it makes me to see a new drawing-bot will do its first correct moves soon

Hello All.

as the official release, at least the RC-Versions of the firmware now seems to support Dual-Scara.... yeehaa.
thx to Jörg, Bondus, DC42 and all the other people made this possible !!!

Before running in a completely wrong direction i wanted to ask you if there is in your opinion a disadvantage of placing
the steppers like in the Photo. This ways both arms have the same "pivot-point". I am not sure If it is a bad idea because of leverage etc. or the firmware runs into some 0-degree problems....

Hopefully i can do my first tries the next days with a new config on the Duet2Wifi.

Best, Johannes

@deckingman said in massive overextrusion, E-Steps are calibrated:

@Enpixa You need to adjust that first layer. The nozzle is too near the build platform. You can see it in the fact that it's leaving a line in the non-print moves between those circular features are the rest is just too squashed. So it looks like over extrusion because it's being forced out sideways due to the proximity of the nozzle to the build plate. Use baby stepping if necessary but whatever means you use, the nozzle needs to be 0.2mm or so higher on that first layer.

Deckingman, you are right, that was due the testing-phase, will increase the distance and show you updates soon. Had tested everything from very close (now) to very far ) Didnt help with the overextrusion.
