Here is firmware 0.74.1 which is a bit of a research project that I’d love feedback on (I’ve started a new thread for that here).
This is an exploration into quantifying frame flex automatically. If you press the “Apply Tension” it will take two measurements. The first measurement is taken with the tension set to Maslow_Calibration_Current_Threshold and the second measurement is taken with the tension set to Maslow_Calibration_Current_Threshold+500.
We can then compare those two and see how much the frame is flexing as the tension increases.
It seems pretty repeatable to me. My default frame consistently gives a result of 0.1mm of flex while my steel frame is consistently worse at 0.6+mm of flex.
Only firmware.bin is needed for this update:
