hi guys im using vcarve 6.0 and my laptop was dying so i downloaded files to new computer since then have problem with the gantry finishing the job but then coming down and hitting against clamp at 0,0,0 breaking the bit. im using shark 1.6. i usually set the zero by touching the bit to material.any idea how to fix this?ive got the zero safe at 1.0 but gantry still comes down to hit clamp

how have you got things set up in your material set up under the toolpathing tab ? ( Not your initial set up when you start a new job )
The material set up that is under the toolpath tab gives you a home position which is where the machine starts & finishes the job
