      @phaedrux

      It seems I understand what's going on.
      I have a remote extruder installed with a recommended acceleration value of 120. If this value is lowered a little, the retract starts working correctly. I also noticed that this happened when the retraction speed was above 30mm/s.
      The only thing I still don’t understand is why everything was without problems during the calibration tests?...

      You need the following to make remote drive work

      low micro stepping low current low acceleration 1.8° motors

      The 40:1 gear ratio is not really well matched to our standard stepper motors. In order to get any speed at the print end, the motor has to go RIDICULOUSLY fast. Once the stepper is going that fast, it has no torque. So high acceleration is impossible.

      I have the same flex 3 drive and found it unusable because retractions and extrusions were so slow.

      @lord-binky Thanks for your opinion, but I guess I have a slightly different view on accuracy.

      @Phaedrux
      Unfortunately all my experiments with frequency have failed. I am still running the old fan with my finger.
      The only thing I can add is that "always on fan" only works with a direct connection to the board.
      When fan is connected to "smart effector", "always on" does not work the same way.
      Regards.

      P.S. I understand that this is not a lot of information, but there is always hope that an idea will come to your bright mind.

      Incorrect readings of the PT100 sensor

      The PT100 should have a resistance of 100 ohms at 0C and about 108 ohms at a typical room temperature. if you use a 2-wire connection then each 1 ohm of resistance in the wires or connectors will cause the reading to increase by about 2.5C.

      @oliof It looks great, but I already have a Bondtech BMG.
      But in any case, thanks for the good advice.

      Also I think you need to enable and calibrate pressure advance in the firmware.

      Also another thing to try is printing a significantly bigger cube.

      The one corner that is always bad is probably where each layer starts and finishes so once the other corners are good you can work on tuning retract length, speed and possibly pressure advance to make that better.

      Have you seen https://duet3d.dozuki.com/Wiki/Connecting_endstop_switches#Section_3_3V_compatible_optical_endstop ?

      Optical endstops have active high outputs, so configuring them for a delta printer is the same as for configuring normally-closed microswitches.

      @vapvap You mentioned "load the filament into the tube and start the print program" so I assumed that on your current machine you manually load the filament though the extruder and advanced it until it was coming out the nozzle. then start the print?

      Basically there are two separate processes going on.

      Setting up the printer so the filament is in the hotend, and ready to print

      starting a print

      sorting out 1) involves getting the filament through the extruder, down the bowden tube and into the (hot) hotend. You can do that by manually setting the hotend to the appropriate temperature, loading the filament into the extruder, and then using the printer controls to push the filament down the bowden tube. until it comes out the nozzle. Or you could to that through some automatic "load filament" mechanism. In our case we have the ability to automate that through a load filament macro.
