Hello,
I am trying to build a CNC machine with a small XYZ stage. The motors are 24V x 0.6A, 1.8 degree/step. The stage uses M6 leadscrew. The motor drivers are A4988. I am using all 3 jumpers for each driver, so I understand that in the case A4988 it is a 1/16 micro-stepping. I defined the bed size in Marlin as 100 X 100 mm. For the control, I am using a Pronterface software. The problem is that with the default 80 step size, the motor cannot reach the endstop switch and the error appears ("echo:Homing Failed Error:Printer halted. kill() called!"). It seems that the motor stops before reaching the endstop switch because the time defined for the homing procedure has ended. Also, I noticed that the travel distance depend on both the bed size and the step size parameters, since when I am increasing either one of the, the travel distance increased. However, I cannot get the correct settings. According to the calculator of the step size (https://blog.prusa3d.com/calculator_3416/), the correct step size should be 3200. However, with this step size, the motor does not move and only produces pitch sound, so I believe this step size is too high. It seems that I am missing something here. What would be optimal settings for my setup?
Thanks.
