Makertech 3D Forum

Hello, i'm still not done with my pf3 and got a lot of problems with cooling and retraction. My So i tried to adopt a EVA hotend to the printer. Here i was asking for it: https://www.forum.makertech3d.com//forum/proforge-3-3d-printing/extruder-fanduct-mount-upgrade I'm not a big designer, but this is the best what was able for me and Tinkercad: Now i have to realign the Z-Sensor and the available hight. Is it better for me to run klipper? My sd card slot is broken, so it would be better anyway. @Johannes Weis Do you got a working klipper version? How i can adjust it? Thank you for the answers.

After switching only a few hundred times between the two extruders, the original servo arm was worn, and the screw had loosened slightly. The result was that the servo arm was no longer able to flip between the two extruders, and a multi-material print failed. I printed a new one, and it worked at first, but wore out again. Should I be using a harder material for a replacement arm? Am I expected to tighten the screw occasionally? A single very large print could have hundreds of swaps, so I'm finding the durability insufficient.

after setting up using the instructions for klipper when i type t0 or t1 the servo always moves tot he same hotend. using install arm will send it to 90 degrees but it is not moving to 10 degrees when i say t0. any one have a fix for this
