Thanks!
I connected everything yesterday uploaded GBRL MI on the Adruino and tried several homing sequences. (It was suggested in a video to use GBRL MI as opposed to standard GBRL as it should be better working with a servo to raise and lower the pen/tool) I'm not sure though how true that is.
I controlled the machine via the Adruino IDE app.
The limit switches on the Axes though don't work yet or are set up wrong when I tried homing the machine.
The motor did not stop when hitting the limit switch and perform a small bounce as it should.
I don't know yet what the cause is.
I might change from controlling directly over the Adruino App to a more visual software this evening. Came across the free LaserGBRL tool which works more graphically than programming directly in the Adruino IDE environment.
The X Axis did not do anything yesterday by wiring both Steppers together, I will try with a second Driver on A today and see if that was the problem or if it has something to do with my non existent programming skills
Really glad that I built it I learn tons of new stuff every day
