Ok so my first real cut with the laser 2 concentric circles for a lid on my vacuum chamber for a perforated casting flask. Both circles gas about 10mm uncut in the same place? I am sure I missed a setting, but not sure which one. Any help would be appreciated. Fixed it easily with a dremel, but would prefer to avoid it in the future. ![IMG_3920](https://us1.discourse-cdn.com/flex016/uploads/arcdroidcnc/original/2X/e/efa1f85cbbdb6d30f5c64d14db200e2cf31ec452.jpeg) ![IMG_3921](https://us1.discourse-cdn.com/flex016/uploads/arcdroidcnc/original/2X/f/fe5aa0fa303e0b7cf6a47ed0c37df19c7bbcde68.jpeg) ![IMG_3923](https://us1.discourse-cdn.com/flex016/uploads/arcdroidcnc/original/2X/4/41f005d9274f4ac249ee19a8b82ee2201907dca0.jpeg) ![IMG_3925](https://us1.discourse-cdn.com/flex016/uploads/arcdroidcnc/original/2X/1/162b571c188d40d8f45b67d3d539e1599db1a6c5.jpeg) ---

Almost certianly it’s because your Pierce delay is too small. The machine is already moving before the laser kicks on Pierce delay holds still until delay times out. this gives a chance for your plasma/laser to blow thru
