Hello,
I am trying to get an alternative printhead which allows high temperature printing to work in my UM2.
Since my new printhead has other dimensions and is a bit larger compared with the original UM2 head, I have set the printhead settings in Cura according to the new printhead dimensions. So far everything ist fine.
But I have two issues:
1.) What is not clear to me is the question if I have to tick the box "origin at center" in the printer settings and what this really does when ticking this box (the original UM2 has neither a tick in this box, nor an extruder offset in both directions). When looking at the original print head, the nozzle is not below the crossing points of the axes - so what is this setting about?
2.) However, my main problem now is that when trying to calibrate the build plate, the head hits the right printer wall, which is no wonder because the printer firmware does not know about the changes done in the Cura print head settings (I guess the changes in the print head settings in Cura are just considered in the new gcodes generated with these settings, but of course not at all in the UM2 firmware). Or do I only have to reload the UM2 firmware with the new renamed printer with the new print head settings activated in Cura?
So I would be happy to learn, how to do a proper build plate calibration avoiding a collision of the head with the printer wall or how to consider the different printhead dimension in the UM2 firmware to avoid the collision of the head with the printer wall.
Any help would be highly appreciated.
