    • 6HC + 3HC + 1LC - is this doable?

      Simple question. I have a 6HC and a 3HC connected together. Is it possible to connect a 1LC into the 3HC, not for multiple toolheads, but just to simplify my wiring up to the print head?

      On the documentation page for the 1LC it does not present that as a scenario, only mentions connecting it directly to the main board.

      [speaking of not using a tool distribution board it says...] "It is also possible to connect a Toolboard directly to the Duet 3 Mainboard 6HC, 6XD, or Duet 3 Mini 5+."

      I figure it should be possible, but before I make an assumption, I would like to know for certain.

      Thanks!

    • Cannot get Hot End Fan to Work

      I've got almost all my configuration done, but for the life of me I cannot get my hot end fan to work. I have the part cooling fan mapped to OUT8 and the hot end fan to OUT7 on a 6HC. I also have a 3HC attached as well, but those fans are obviously on the 6HC.

      The fan works - if I set it up as the part cooling fan, it will turn on when commanded. Both OUT7 and OUT8 work. But when it's set up to be a hot end cooling fan it just will not work. It never turns on when it heats up, and I am completely stumped.

    • RE: Probe already triggered at start of probing move

      @Phaedrux yes - true, the S values were missing. According to documentation though I seem to remember that it's assumed that motors are S1 and it's not necessary unless using S0.

      I set the microstepping from 16 (default) to 1 because I have leadscrews that that go 2mm with 200 full steps. So to get it to go 1mm, according to how RRF does things, having it at 16 necessitated defining 1mm as 1600 steps, since it uses microsteps as steps, even though they're not full steps. One full step would produce 0.01mm change, and I didn't need any greater accuracy than that.

      At any rate, I've updated both of those and the behavior is unchanged. It does seem to be however that updating the firmware may have fixed it all, as it is no longer issuing the error.

      So that makes me curious - are either the missing S or the microstepping the cause of the problem, or is it a firmware issue and a known bug at that time?

      I ask, because I have spent countless hours over the past two days trying to troubleshoot this, and I'd like to know where my mistake was. 😖

    • RE: Probe already triggered at start of probing move

      @Phaedrux Homing for X and Y both work properly, and are always done before I attempt to home Z.

      Probe deploy is:

      M280 P0 S10
      

      and probe retract is:

      M280 P0 S90
      

      Both function as expected. BLTouch is lit up red when retracted, and light goes out when deployed.

      Homeall is not complete yet, because I haven't got home Z to work. When XYZ all work I will concatenate all into that. I've completed the static and dynamic tests in the link you sent, and calibrated Z probe trigger height to 2mm.

      I just finished shutting everything down, pulling wires, and testing for continuity. No shorted wires, all wires testing properly from one end to another. Genuine BLTouch 3.0, and wired properly to spec per documentation.

    • Probe already triggered at start of probing move

      Alright, I am absolutely stumped. I have been building my config files from scratch, based on a generic RRF file, as the RRF tool doesn't accommodate for cross gantry dual X Y triple Z setups. I'm using a BLTouch 3.0

      I keep getting the "Probe already triggered at start of probing move" error. Everything seems to be working the way it should. After homing X and Y, I go to home Z. It will lower the bed, move XY to center, deploy the probe, raise the bed, and when the probe touches it will retract, lower down a bit, and then give that error.
