this is not really "sensorless" as we have a magnetic sensor system here. ;) But, we would need to wire a pin of s42b back to the endstop pins of...

@AbeFM the S42B keeps track of its absoulte position as it is counting rollovers as far as I know. EDIT: looking at the very similar closed-loop stepper "Servo42B" from MKS,...

@swanepoeljan yes, you are right - forgot about that. It should not be too difficult to copy that function and generate a trigger on ~2° and pull one of the...

@swanepoeljan You can DIY it in but not on S42B. I saw a "wiring example" for the STM32F030C8T6 here: https://github.com/makerbase-mks/MKS-SERVO42B/issues/11 ;) So far, for 3D printing I did not see...

maybe we just wait for this campaign to rum: https://www.ogadget.com/x/ananasstepper3

Oh, you should really test what you can do with a geared extruder setup like BMG (my favorite) or a Titan with closed loop. For my direct drives I run...

Maybe you think of it the other way around. I use a much higher current limit with closed-loop than the rated RMS current of the motors. In open-loop the drivers...

Regarding the FR for sensorless homing one possible way to implement it: 1. Copy the red-LED function with a lower threshold of ~0.4deg (quater full step sounds ok?) 2. use...

I implemented the functionality in this PR: https://github.com/bigtreetech/BIGTREETECH-S42B-V1.0/pull/27

That would be one nice solution. But I did not yet try this with a full mechanical setup but only with a small lever. But without Boot0 accessable we would...
