hi all! finally the polargraph seems working well, the only issue i cannot understand is that the printing area is stretched: vertical size is shorter than the image loaded...
any idea?
thank you

Now that I've thought about the problem being only height, it occurs to me that maybe you aren't properly homing the gondola before starting the drawing. Or maybe you move the gondola by hand after homing, which wouldn't be good.

Hello guys,

I'm having a similar issue.. I'm trying to draw a sample of shapes - circle/square/pentagon. But for some reason the drawings are always skewed and do not look at all like the shapes. I've tried this on a few of the pixel styles and always with the same results.

The overall shape is a semi circle at an angle but obviously filled in with the different pixel styles...(if that makes sense!) would you know why this would happen?

Also, I was wondering if perhaps you could give me a practice drawing to get started on, along with the different settings I should use, ie grid size/sample area + motor speed etc..?

I'm getting there through trial and error but it would be very handy to have a place to start so I know the settings are right and what the extreme highs and lows are.

thanks for all your help so far
