Yeah, I didn't mean servo, I intended to say solenoid.

first thing I see is the offset must be way way off - look at those circles in the corners

yeah, that's true, solenoid being wired "backwards" wouldn't actually effect anything. The signal going to the solenoid is inverted, that could be driver, software, or motherboard issue.

Thank you both so much! I'm still playing with the settings but this has helped me move in the right direction! Cheers!

It would be really a great thing if the solution was to switch those two wires! I guess we'll never know.

You have to account for two distortions, and the image will always look a little off if you're not looking at it exactly straight on. First you need to account for the curve of the glass. Since glass is an inverted truncated cone use the diameter of the cup about where the middle of the design would be. Easiest way to do that would be to take a string and wrap it around the cup where the design will be, that will get you the circumference. Divide that number by Pi, 3.14, to get the Diameter to use in the equation below. H = h/w*D*sin(w/D) h - height of image w - width of image D - diameter of cup H - new height for image And here is a discussion on how to account for the tapered shape of the glass which includes a spreadsheet to do the math so you can create a template. Even with all this, there's still can be a bit of experimentation to get the design perfect but I've been pretty pleased with my results.

The cutter head (Z axis) functions with an ELECTROMAGNET (neither a servo nor a stepper motor ---- those motors are for the X and Y movements, not the Z).

Welcome from accross the pond, are all of the carriage wheels locked onto the rail, sometimes they come off in shipping. There should be no clinking or clunking. Also we have seen where. People have not gotten the ridge of the blade holder under the retainer when installing it
