I am going through the pain right now............ I find I can do the calibration but end up with a stepper that when I give it 10mm moves about 7.8,...

Well so far the theory is correct with the switch positions but the problem still exists, pretty average company BTT

I I ever solve this I will share it from the rooftops bloody annoying

> @NZ-Nitro I think that has to do with the steps per revolution, the S42B uses 256 steps instead of 200. (Which is 78%) It's poor design, look for my...

Another person being driven mad by this problem, but also calibration accuracy as an example I give the axis a 10mm command and measure with verniers a 7.5 mm movement...

More testing as I have seen comments about the 5v missing, I am getting 24v and also 3.3 v at the motor so that should be fine

Testing cont changing dip sw 3 and 4 makes no change to the length of movement changing #define DEFAULT_AXIS_STEPS_PER_UNIT { 80, 80, 800, 100 } makes no change to the...
