Had an odd thing happen last night. I do topographic 3D maps and for some reason last night about 4 hours into a carve something happened that made my CNC decide to carve a completely unrelated path. It plunged super deep, did an odd cutting pattern and seemed to be carving something else. Has anyone had a glitch like this happen? No static electricity buildup or anything that would have shocked the CNC, as I had no dust collection going. And cut preview in Vectric was perfectly normal. ![IMG_7784](https://us1.discourse-cdn.com/flex022/uploads/onefinitycnc/original/3X/f/c/fcacf63b9385723186d3bce39ac07297f3c2926b.jpeg) ---

Hey Ben, > [@LostWoodsCreative](#): > > Has anyone had a glitch like this happen? yes, this is reported from time to time in this forum. Use the search function, e.g. search for [Z plunge](https://forum.onefinitycnc.com/search?q=z%20plunge). Often it’s the Z cable or its connector, but it can be also the bit which becomes loose due to dust inside the collet.
