First Print with DSH and Klipper

in Proforge 3 3D Printing

Finally got the DSH hotend to work with klipper and the first print was pretty decent. Now I need to fix the retraction issue.

Damn, respect! Can you share the klipper configuration?

Sure I can share. I wonder if it would be best to share in the current klipper repo for the proforge 3

Also a couple things to note. Klipper cannot send the servo into negative angles. So I have set the servo so the angle = 0 activates the right extruder (Extruder1) and I found at angle=190 the left extruder will be used (Extruder).


Also Cura seems to always inject the extruder code ahead of the "start gcode" So the printer needs to be homed before setting the offsets. I added a Safe home to check if the printer has been homed already. Its more of a workaround at this point. Come to think of it I should add a specific CURA T0 macro that calls Safe Home the T0. hmmmmmm


Also still tweaking the configs.

@Andrew Lee Thank you very much for the config, file is uploaded. You could borrow from the most recent direct drive config and add Start GCode and End GCode. Does DSH have the same thermistor as the DD?

Also does 20mm distance to the edges work with the probe being 32mm from the nozzle? Didn’t dare to try ._.


Now I just have to figure out how to add folders to GitHub :D

@Andrew Lee oh shit, just realized that the text file isn’t actually the DSH file. But be sure to share it so we have some sort of an organized hub :)

@Andrew Lee Are you still developing your config or is this the latest version? Think of converting mine to klipper now I have my missing parts (bought them myself)

I ended up switching back to the direct drive hot end. Too many problems with the servo dying

@Andrew Lee is it the same problem in klipper like in marlin that the servo stays powered on? In latest marlin makertech changed a setting.

I think with klipper is always on. I did wire it up to the pi and then klipper to send gpio commands to activate the servo. Seemed to work well for about three weeks but the started acting up. I rarely used the dual filament anyways so decided to go to the direct drive hot end. One day I want to get an enraged rabbit
