When I recently built it it run twice like a charm and then almost all cuts failed. That was due to the lack of rigidity because all the piping was aluminum with 2mm wall thickness. I replaced recently all the piping with solid chromed steel round bar and the rigidity issues wen’t away (I still need to swap the z axis piping, I’m waiting for a special drill bit to tap m5 threads to the round stock). With all these changes, today I just made an aluminum test part for the dyno and no issues at all, everything went well. I will try to slowly replace all the 3d printed parts with steel machined ones (except the core) to make it even sturdier. I’ve seen people machining steel with the same cnc but I still need to try it with all the changes I made. Thanks for your comment!!
Very nice work! Side note, but do you like the 3d printed CNC? Also have you tried cutting aluminum with it?
