The CNC was controlled by a very puny 32-bit computer with 1GiB RAM. So i transplanted the disk and power supply into the discarded vinyl-cutter computer which catapulted our CNC system into the 21st century. Hooray! It is now based on a Core 2 Duo E8400 with 4GiB of RAM and I am testing it right now by cutting LP records :) greets, amir
