[FIXED] Upper limit too high?

[FIXED] Upper limit too high?
Hi,

Great fun tinkering with the board!

One thing I noticed: when drawing an image (like the world map example) which just abouts fits on the glass, the upper few centimeters (I think about 5 cm) are being drawn above the glass.

I tried putting the glass somewhat higher in the legs, but that only partly solves the problem.

Anybody else has this?

Looks like you are setting the drawing header starting position too high?

Could you send a picture, it will help :-)

Sorry, forgot that might be useful... Angel
Here are 3 pictures:

Looks like a "belt not tense enough" problem. Check the tension of the belts, from the images and the way the iboardbot is drawing looks like they are too loose.
And set the glass completely inside the legs, that doesn´t really fix the issue ;-)

The same drawing with the belts set with the correct tension:
   

I hope it helps

Hi,

Tightened the belts, much clearer image! Thanks!

However, it still thinks the glass is higher (and so the image is being "cut off"). Any thoughts?

I've added 2 images: in one you see the board drawing above the glass, and in the other you see the final result (with much straighter lines, and thus a sharper image).

You got your pen holder upside down...pen supposed to be on the bottom and not the way you have it. So deassemble the pen holder and turn it 180 degree
