    • RE: Temp going to zero at tool change

      So I figured it out. My starting script was breaking things. For single extrusion (tool T0) it looks like this.
      M140 S[bed0_temperature] ; set bed temp no wait
      M104 S[extruder0_temperature] ; set extruder temp no wait
      G28 ; home all
      G1 Z250 Y-140 F6000; Lower nozzle for easy wiping of ooze
      M190 S[bed0_temperature] ; wait for bed temp
      M109 S[extruder0_temperature] ; wait for extruder temp
      That will start warming the bed and hotend and then home, then drop the head to a reachable location in relation to where I'm sitting at my desk. What I had to do was add tool 2 (T1) into the mix for temp setting.
      M140 S[bed0_temperature] ; set bed temp no wait
      M104 T0 S[extruder0_temperature] ; set tool 0 hotend temp no wait
      M104 T1 S[extruder1_temperature] ; set tool 1 hotend temp no wait
      G28 ; home all
      G1 Z250 Y-140 F6000; Lower nozzle for easy wiping of ooze
      M109 T0 S[extruder0_temperature] ; wait for tool 0 hotend temp
      M109 T1 S[extruder1_temperature] ; wait for tool 1 hotend temp
      M190 S[bed0_temperature] ; wait for bed temp
      I just added the last two m109 commands, so I have to test them to confirm they don't mess with anything.... but without them the tool changed happened correctly and I'm currently printing.

      It does help, thanks. I’ve not noticed any Z issues that I thought were from microstepping. I’d just always heard the “magic Z height” for printers to utilize full step increments as being desirable. I’ll just say eff it and keep letting KISSLICER do a brilliant job of using dynamic layer height.

      Thanks again everyone. Trying to work out a replacement linear rail solution for the X axis to remove some artifacts and then I think this printer will be quite brilliant.

      @droftarts not sure exactly what the screw is for the Z. Was just told it was a double threaded rod with 8TPI. I’m not versed on them or how to identify what is what.

      My interpretation was always that it was simply easier/more precise for the stepper to hold place on a full step. But that’s entirely based on my limited knowledge of steppers and the implementation of microstepping.

    • RE: Duet Maestro in MakerGear M3

      Quick question that I didn’t find the answer to.

      A full step on my Z is 0.0158mm. So is it best to leave that number as is or better to just round up to 0.016? I didn’t know how the firmware handles decimal places. Same thing for the slicer....utilize multiples of 0.0158 or just use multiples of 0.016?

      @Phaedrux thanks for everybody’s help. I went ahead and knocked out a quick test print and all looks good. It looks like the duet is removing the artifacts I was experiencing with the stock Rambo board. More testing to confirm, I will play with it more tonight after I get back home from work.

      I forgot that I plan on running the quick 9 point mesh at the start of every print so no need to reload the height map. But good to know if I decide to remove that from my starting process. Thanks again everybody.

      After bed mesh is complete do I need to reload the height map after a reboot of the board?

      Can someone give a brief explanation of the deviation and error results?

      More specifically “error m557: bad grid definition: Y range too small”

      @Phaedrux it said the Y value too small
