Magician drawing lack precision


#1

Hi

I have a magician robot that want to use to draw with a ballpen and found that its not precise when drawing with dobotStudio.

For example choose a sample shape like an square and the robot does not draw the corners square, more like a round one. If i try to draw an star or whatever the same behavior happens, more complex its the shape worst is the result, i can reproduce that with simple shapes drawn with dobotStudio.

I need to recalibrate the arm or anything to get shapes drawn correctly??

Thanks!

This is a sample when drawing a grid… you can see the distortion

I’ve got the exact same problem. Please help.

That happens when the pen makes too much pressure over the paper, try to adjust so very small force is applied. I ended making a new pen holder with 3d print where the pen makes contact by gravity

Hi, natxopedreira. The main reason for this is that the pressure on the paper is relatively large, So I recommended that you reduce the pressure between pen and paper. Or you can use Mark pen, That would be much better.
