servo for pen up and pen down about grbl-plotter

[svenhb]

You could try to work with a ramp.
1st find the zero value, where the pen just touches the paper:

2nd enable the ramp:

Then a line will be drawn by such code:

I do not have P91 Pen Zero

Now I'm stuck. I have Unknown Status - and can't do anything. Laser Grbl and UGS works but not GRBL Plotter.
Reinstall, restart, reload - nothing.
Any Idea what is wrong.

I do not have P91 Pen Zero

Just press "Advanced settings"

I have Unknown Status -

Are you sure the serial connection is done? Perhaps wrong port?
You may "Scan Ports" and try an other port?

Some time a hard reset is needed (my experience with Arduino mega) to be able to connect.

Thank You. Regarding servo - I have to try it.
Regarding U known Status - today all is OK. I do not know what was wrong before.
Thank you

A like to assign one button to Pen in Zero position.
For Lower Position the line is M3 S#GMIS
For Upper Position the line is M3 S#GMAS
What line to be for zero(middle) position M3 S#G???

I found GZES for PWMZero and
GCTS for (PWMUp + PWMDown)/2 (not sure for what it could be good for)

[Marmadoc]

Perfect. Thank you
