XY Plotter Bad Vibrations

#1

I have a XY Plotter that is vibrating like crazy, and the lines are not smooth. Another problem I am having is the mDraw program doesn’t seem to work properly.

What are the x and y setting?
Speed setting?
Clockwise/Counter Clockwise setting?

I ask because the servo motors take the pen out to the upper right hand side of the plotter as if the setting are too large for the actual space. I think the unit ship with 380mm and 310mm as the settings. To get it to draw I have to make the picture tiny 27mm x 19mm and put it in the upper right hand corner of the x y rectangle. It kinda works but the lines are messy.

I have tried adjusting the torque and I can get the vibrations to stop, but the pen doesn’t move when I do that. It almost seems as though the limit switches are not working properly, but at this point I have no clue.

I want to use GCode, but I need to know the unit is working properly first.

I was able to solve all the problems. Turns out I had two problems.

  1. The first was the Y axis limit switches were backwards.
  2. The second problem was the dip switches on the step motor boards were set to LLL ( L = Low). Once I set them to HHH ( H= High) the problems were solved. No more vibrations and the Plotter now draws correctly.
