I need someone to answer some questions about clear acrylic edge lit signs.
When I do center line carve it does not do a clean and neat carve! When I carve it lithopane style, even though I use a solid black background
for my import, the carving bit still drags across the piece in places which ruins an edge lit sign. HELP!!!!:(

A picture would be great to see exactly what you are talking about...
Centerline Text is designed with a feed rate for WOOD... Cutting Centerline Text in Plastic could give you serious problems as the feed rate is too high...
Another thought for text on a Litho is to type the text in a font called MODERN that is a Single Stroke Font and IF you selected OUTLINE Mode and depending on the size of your text.... Selected the Carving Bit for small text less than 1/2 inch high it might work....
I use the Modern Font for my Wood Signs and the text is 2.25 inches high and I use a 3/8 inch Plunge bit and it works great.... For 4 inch text you would need a 1/2 inch bit.. For 1 inch text a 1/4 inch bit.... And Like I said above, the Carving Bit for smaller text.... You would need to play with it to see what works... IF you use the 1/8 inch Cutting Bit and PLASTIC.... IT could SNAP the $40.00 bit in PLASTIC... That is why I say try it with the 1/16th carving bit...
Good Luck,
AL

If the carving bit is touching in areas where you don't expect it to carve, you can raise up by using masking tape or taping a playing card or two on top of the acrylic where the CW measures the thickness. I've had the machine carve off a layer of paint if the stock wasn't completely flat--it doesn't raise the bit up any more than it thinks that it needs to when travel to a new section of the carve.
