      @leprint Funny you should mention that because I have adjusted the tension and lubricated these things many times but what I find curious is the height map DOES change when I adjust the tension of any of them. I have made a spreadsheet of how I adjusted each tower and recorded the height map afterwards. Then, I would save that height map screenshot, adjust another tower, then record the results to see if I could find out what's causing it but I could never find a clear answer for the cause of those dips and peaks you see in the heightmap. I even lubricated the channels they move up and down through and made sure every bearing was not seizing or clicking with no avail.

      @dc42 Okay, thanks! I do think the docs could be clearer about that, although in fairness it's a nonissue for most motion systems. Appreciate the help!

      @tkln I guess, that's not doable right now, but you could try sensorless homing for one of the motors on each tower.

      Programming Z probes connected to expansion boards is not yet supported. For now you need to temporarily connect the Smart Effector to the main board if you want to change its sensitivity. I've logged this issue: https://github.com/Duet3D/RepRapFirmware/issues/815

      @dc42
      the math they use calculates the leg(s) length first and then replace that by the required servo angle and even the microseconds for PWM duty cycle.
      That's the point where it gets specific and needs new formulas. Either for industrial servos or for Deltastyle tower arrangement with steppers.

      Beside that difference it's quite the same: both systems have a fixed base/frame and a moving platform connected by six rods.

      @jasperg that kinematics isn't currently supported in RRF but it could be added. There is a brief overview of how to add new kinematics at https://github.com/Duet3D/RepRapFirmware/wiki/Adding-New-Kinematics. It would probably be possible to implement it as segment-free kinematics.

      M665 R134.4 L271.5 B116 H283

      Thank you again. This is all Greek to me so I rely heavily to you and the community for help.

      i am greek and most of these looks greek to me to ....

      the M665 is what defines a printer as a delta to my understanding.

      M665 Rxxx( is the radious of ur builded printer the internal one), Lxxx( the length of the rods that hold ur effectors) Bxxx( is the radious of ur bed) abd Hxxx( is the height of ur nozzle to the bed when the limit switces are enabled) .

      @dc42 Yes, that is what I thought as well.

      Do you have any idea why timing is so far off? Like I mentioned above, I successfully tested these motors with the same power supplies and a MKS SGEN controller board with timings of 3:3:6:6. The MKS SGEN board provided 3.3V logic, so if anything I would have assumed it would need more time to activate the opto-isolators due to the underpowered signal.

      One concern I have is these motors are supposed to run at a maximum pulse frequency of 250 kHz. Is there a way for me to set that for the Duet board?

      I wanted to add this has been a educational thread for me as to some of the constraints on Delta designs.

      I don't know if I would switch to a smart effector over the SE300 but a revision that includes this would make me give consideration to losing the print area outside the triangle of the towers.

      here is another idea.

      print these https://www.thingiverse.com/thing:2519593
      they will also provide good noise dampening.

      now you have space underneath the delta where you can mount the duet without interfering with the motors.

      @bassco How did you configure the Smart Effector for Klipper?
      I can't seem to find any info on it 😞

      This is my current config:

      [probe] pin: PC1 z_offset: -0.1

      The wiring was okay and was in working order before going Klipper, so that's not a problem.

      @taconite said in bed mesh compensation unclarity:

      Question: Why is it not possible to load a previously saved height map, without establishing the Z=0 datum? Because of the homing of the axis the position of Z=0 should be the same (Ignoring possible jitter in the homing switches).

      on a delta this should still work. if you just ignore the message you should be able to print just fine.

      Hi ! I know you've solved the problem you initially asked about. I'm wondering it you could give my some info on how tricky putting a Duet board on a WASP delta was? I have a WASP 60100 (build 2017) and would love to upgrade it with a Duetboard and maybe a E3D Volcano hotend. But, I'm not really sure what I'm getting myself into 🙂 Would you mind me asking a couple of newbie questions about your process?

      As @carlosspr says. For stall detection to work, the feed rate in your G1 S1 commands must be at least (60 * m915-h-value / full-steps-per-mm) . If your printer has 80 steps/mm @ x16 microstepping, that's 5 full steps/mm. You are using H200 in M915, so the minimum G1 S1 feed rate would be (200 * 60)/5 = 2400.
