Attached X and Y endstops, mechanical switches for now, wiring was trivial.
My X axis does 5000 steps to travel 12 cm with small 8 tooth pulley. That's 0.025mm per step not 1/4 of a millimeter but 1/40th, no wonder it's slow. I will change microstepping from 1/16 to 1/2 to gain x8 speed and still keep the resolution at 0.2 mm.
Meanwhile i wonder if my UBW has enough pins for everything.
X axis 2 out
Y axis 2 out
Z axis 2 out
Extruder motor 2 out
Extruder heater PWM 1 out
thermistor analog 1 in
X end stop 1 in
Y end stop 1 in
Z end stop 1 in
Total 13
One spare pin left which can be used to power off the stepper drivers for example.
