    • RE: TMC2208 Causing Duet WiFi to reset

      @dc42 Oh you know what, I think the ground connection did get separated. I did not know that was a thing. Oh well, good to learn 🙂

      I have a duet6HC mainboard that I connected and will finish my project with it. It’s a duel extruder add-on for my ender 3. I will post when its done!

      @o_lampe Thanks for the link. The wiki is super handy!! I also found standalone to be the easiest in prior setups—the current setting potentiometer is pretty finicky though!

    • RE: TMC2208 Causing Duet WiFi to reset

      @dc42 Thanks so much for your advice! I believe it is a stepstick format. I didn’t realize I connected a 12V capacitor across the 24V power input to the motor driver. Suffice it to say the capacitor popped. Now the board’s wifi network is not showing up anymore and I can’t communicate with it over serial. LEDs are still illuminated on the duet wifi. Do you think I could’ve killed the board with this mistake?

    • TMC2208 Causing Duet WiFi to reset

      Hello, when I send a move command to the external motor driver, connect through drive 9, the duet resets itself. I’ve checked the wiring with the stepper motor and it is correct. There don’t appear to be any faults. I’ve noticed before that the TMC2208 causes significant voltage spikes when it is in use in other circuits, so maybe this is the problem. I don’t have any decoupling capacitors placed at the moment. Please let me know if you’ve encountered a similar problem. Thanks!

    • Pressure Advance with Air-Powered Syringes

      Hey printer people, I have a quandary that I would love to hear your thoughts on. Can the pressure advance setting could be made to work with an extruder that uses air pressure, instead of a stepper motor?

      In my system, the extruder syringe is driven by a valve that turns on pressure whenever a g1 command is sent with an extrusion amount greater than 0. So far it’s working such that a higher extrusion feed rate means that the pressure is on for less time so less material is deposited, whereas with a really slow feed rate, the pressure is on for longer so more material is deposited. This seems like the inverse of how the pressure advance setting works, where a higher extrusion feed rate correlates to more material deposited. Can this be rectified so that pressure advance goes slower when it wants to deposit more material, and vice versa?

      Please tell me what you think, I’d love to hear your guys’ thoughts on the matter.

      Cheers,
      Noa

    • RE: Duet 6HC Short to ground error

      @bearer Thanks for your reply! I saw it after the post and sent a message to duet. They got back to me within two hours and said they are working on quality checking the rest of the 6HC boards before shipping out replacements.

    • Duet 6HC Short to ground error

      I recently got a Duet 6HC Mainboard. It connects fine through the web interface, but the motor drivers report error: short to ground every time I try to write to them. The serial number starts with WD41.

      Cheers, Noah
