thanks. I was thinking of pcbs, but will now probably use this to cut acrylic parts needed for a pcb machine (cyclone). Generally this is a way of staying young at 70.
unfortunately I have printed more than half the machine in abs. I switched to abs because I had a lot of trouble making pla stick to the heated bed, but maybe I will try again. so far the parts look usable. I have just printed the four corners and the sliding x and y.
