Servo doesn’t work

[Anonymous]

So, I managed to get up and run my own version of DrawBot (thanks to Dan a lot for the support !)

Now I am trying to implement a pen with the servo, but somehow it doesn’t work –
1. I know the servo is connected properly since the basic “sweep” works OK.
2. I know the Java GUI works OK since I manage to jog the steppers

but still – The servo doesn’t react (no reaction when pen up/down command is sent.

Any idea ?

Finally I managed to make my servo to work,
when ever the G-code says something like that “G3 X-6.7609 Y42.1336 Z40”
everythiung is OK and the servo lifts the pen (X and Y takes care of the location and Z takes care of the pen servo)

Th problem is that the G code produced by Cambam (Engrave) generates something like:
“G3 X-34.3358 Y-21.9489 I-0.038 J-1.8284” instead –
hence – the pen doesnt react.

How can the Z command be generated by Cambam ?

in CamBam I set the material to be at 45, the cut depth to 0 and the travel depth to 90. then it should genereate only Z90 and Z0 in the gcode.

i and j might be arc commands? They’re a separate issue.
