    • RE: Ender 3 nothing working right

      I think it is amazing that you have installed an Duet wifi in a printer that cost almost the same as the duet 😄
      Looking foward to see then end result. 🙂 👍

    • RE: Reverse math for 3-point auto leveling?

      Finally to the point where im satisfied.

      Biggeste change was changing to BL touch - After I got my hands on an thermal/IR camera, I could see that the bed was like a mirror for the camera, so that's why the IR probe didn't work good enough

    • RE: Duet Wifi limitations - what are your experiences?

      Biggest limitation? My imagination and understanding of the Gcode commands -

      Other than that:
      Missing stealth chop on the duet wifi, but spready cycle is okay -
      12V fans on a 24V setup is only possible with external hardware (duex5 or an regulator)

      For a small retrofit, I would go for the Duet Maestro, unless the print is complex (multiple extruder, multiple motors for auto leveling Z, etc.)

      I use the paneldue, but 90% of my work is done through the web interface.

      That is beautiful! looking foward to see print quality if it is as pretty as the printer 🙂

      12V fans on a 24V setup is only possible with external hardware (duex5 or an regulator)

      Just to clarify, the external hardware is simply to supply the 12V. It can be a $3 buck regulator from eBay or Amazon. A wiring example is here.

      Yup - A small buck converter is enough - or if it is a small low power fan like the 30mm E3D, a linear 7812 is also fine.

      Your homeall and homez place the probe at different locations. Make them the same.

      Did this make any difference?

      No not really

    • RE: G29 / 3 point bed compensation - always tilted slightly

      @CaLviNx I dont have one of those tools (yet) but the surface of the bed is a cast aluminium plate that is bought with a really flat surface, so Im suprised if its not flat. As I see it in the first picture, it looks like a flat planar that is just tilted, and not bend.

      I'm gonna get the offset working again, and then I'll try to place a bit around with the Z-leadscrews placement and see the impact on the leveling.

      @sinned6915 said in G29 / 3 point bed compensation - always tilted slightly:

      Are you certain that you dont have a dropped corner on one of your axis?

      Im pretty sure non of the corners is dropped - But even if one corner is lower, shouldent the whole system stay "parallel"?

      Im wondering if the M561 in my HomeZ.g have anything with the offset to do?

    • RE: G29 / 3 point bed compensation - always tilted slightly

      @Phaedrux Hmm....

      That got me thinking - I Use the X30 Y80 because that places the probe not that far from my first lead screw and that saves time since it doesnt have to move when it starts the 3 point leveling - But! since it is not level when it does the first zeroring of Z, will placeing it off center, make the axis it rotates about not centered also? Or since its a plane, it doesnt matter?

      But I'll change it when I get home

      Increased the current to 1200 - still gets the large offset

      M574 Z0 ; Set endstop Z to be probe

      thats not the command for Set endstop Z to be probe
      this is

      Your thermistor is configured incorrectly. Find the correct Beta value in your thermistor documentation.

      M906 X1200 Y1200 Z800 E800 I40 ; set motor currents (mA) and motor idle factor in per cent

      are these correct? what stepper motors do you have?

      The motors are all E3D high torque motors rated at 1.6A, except the extruder which is a small pancake stepper - current seems okay on it - Will look into the thermistors and change it from M574 Z0 to Z1 S2

      EDIT: I got the Z0 from the Gcode page
      "The S2 option of M574 is intended for use only when axes other than Z are using the Z probe for homing. The only printers known that do this using Duet electronics are the RepRapPro Ormerod, Huxley Duo, and Mendel Tricolour machines. When using the Z probe to home Z, M574 Z0 should be used."

      in the start g code.

      G28
      G32
      G28 Z

      So I tried that, but that gives me a fun offset.

      I removed G32 from Homeall and Homez - Then homed all axis from the DWC, and then sent manually G32 and then G28 Z. Then I probed the bed with G29

      @Martin1454

      i would advise not to have the G32 in the homez, as the G32 invalidates z=0.

      while analysing change the 3 point with points close to the leadscrews.

      Where would you place G32 then?
