XY plotter pen down/up, can you help me?


Hi Makeblock,
My new XY plotter runs fine, but lifting up/down the pen seems to work vice versa:
The servo lifts up, when clicking “down” and vice versa.

I can handle this by changing the up / down values in mdraw and raising the pen arm on the back, but that is not a satisfactory solution.

Windows, mDraw v1.2.1,

Could you please give me a hint?


Take a picture of the pen up/down mechanism,might be wrong servo orientation


Sorry, you also same product, same problem? Exactly same words as this post:
