Hey, I am struggling with a few of my problems: The robot is AR3 modified to AR4 (teensy 4.1, teensy4.1 program with cui encoders, plus endstops I modified for inductive sensors). The encoders in these videos are disabled. In the program I changed the lines through the inductive sensors (to align the axes.):: //degrees from limit switch to offset calibration float J1calBaseOff = -1; float J2calBaseOff = -13.1; float J3calBaseOff = 10.4; float J4calBaseOff = -1.5; float J5calBaseOff = 87; float J6calBaseOff = 17; float TRcalBaseOff = 0; My problems are the strange behaviour of axis 4 when driving axis X. Is this rotation normal? The second problem is that the gripper is not kept parallel to the base. Additionally, axis 5 after axis calibration has an angle of 0 degrees. When I go to 90 degrees (as in the video) it has about 92~3 degrees. Is the value of steps per degreee incorrect? And how can it be calculated? The controller's microstep settings are as in the manual. Third problem is this humming sound of axis 4 stepper motor. After connecting it to another controller (TMC2208, TMC2209, DRV8825) it does not make this sound. (But this is the smallest problem).

Hey, I'm just trying to run the program for the AR4 version, but unfortunately nothing happens. The program crashes immediately after starting. I checked this on two different computers. Win10. Should I install something additional? Python for example?

Hey What do you use to provide air to the gripper? I'm looking for some silent compressor that won't disturb me in my room.
