Hi,
I'm currently building a pen plotter using Marlin firmware v1.1.3.
I'm using RC servo to lift the pen instead of stepper, so my Z axis control is M280 P0 Sxx instead of G1 Zxx
When I try to draw something the home axes command finished correctly, but during the first move the pen went up and down several times (creating a dashed lines) and didn't lift during the draw (just drawing in the air)
It looks like all of my M280 commands take precedence of my G0 and G1 commands.
I was looking into the source code (of the Marlin) but found any explanation for this.
If somebody has any idea, how to correct this please let me know.
Thanks,
