First Print with DSH and Klipper

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

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

I'm still working at a klipper config but my first tests with adding a dwell command of a 1' followed by a power down of the servo, seems to work. G4 P1000

SET_SERVO SERVO=extruder_servo WIDTH=0

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.

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 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)

@Dries Douterloigne I can only speak for the direct drive side but that one works perfectly fine.

No clue when or if Andrew will share his config :/

Damn, respect! Can you share the klipper configuration?
