    What exactly is the material you are carving? Did the bits plug up?

    Have you checked the spindle for play? Does the bit seem to be held firmly by the machine? Does the bit wobble at all?

    Posting a picture of the litho might help us see what happened.

    WAG.... Ask your supplier if the Acrylic is CAST OR EXTRUDED? Cast CAN be Engraved or Litho... Extruded can be harder and is not recommended to be carved or engraved as it will damage your equipment... ANY chance a BLOB of Acrylic MELTED on the Tip and FROZE to the SHEET, HENCE SNAPPING THE BIT.... Inquiring Minds want to know....

    So here is a picture of one of the lithos the bit broke on, I included a whole shot then one close up with the bit tip still in the material. As far as the answer to the questions. To the best of my knowledge everything is correct nothing loose no wobbles fits tight. Again no issues with wood projects, I have included a picture of the latest wood project done after the litho issue started. A gift to my brother who retired from the air force. Also ran off two wood clocks today with no issues. Click image for larger version.

    It also looks like the path went askew?? I presume you have that in a sled. Is the fit tight? Looks like there was movement of either the sled or the corian itself.

    Nice thought, didn't think about the sled, tight fit and taped but only on two sides not all four.

    It looks to me like the bit was not cutting right just before it broke. Maybe plugged or somehow dulled. A mystery.

    Or melted... Is that the broken tip of the bit still inside the plastic?

    Did any of these happen right after you stopped the carving to do some cleaning?

    Yes the machine stopped and told me to clean the y rails, I cleaned them half hearted on the first one. after that I cleaned up the entire machine really good. On the 2nd one I cleaned as good as I could. All 3 breaks happened after the clean y rail came on. The breaks occurred within 10 seconds after I restarted the carves
