I did the robot + name since it seemed a good traditional test run, but really wanted to test out one of my primary use-cases: Embossing plates cut from delrin (maybe brass when my comfort level in design & machine tuning improves).
Results? I mixed, but a fully usable success!
The first photo shows the carved delrin, from a 0.25 sheet… the second tool path was with a 1/8 bit to cut out a rectangle around the celtic weave and it… well, failed. I’m not sure why, I think the bit might not have been secured tightly enough in the collet. It was supposed to run 5 passes at 0.05 cut depth. 40 feed rate. Instead by the third pass it was cutting the much deeper and in the space of about 2 seconds bottomed out to nick the waste board and then jamed enough to pull itself free of the collet at an angle.
But the pattern itself was fine, so after a bit of sanding around the edges I pressed an impression into some leather. The second photo shows the finished leather ring.
Stay away from aggressive cuts. Thumb of rules for rigid X-Carve is half of the bit size for depth per round. For new equipment without any upgrade or customizing is 1/4th of the bit size. That means if you use .125" bit, cut depth must be around .032" .
Haha, stop. I have my shopping asket full on drillman1’s ebay page. Just have to get around to buying them. Still trying to suss out the right bits I need
Hi Alan, what sort of upgrade or customizing would apply for something like this? For reference, I’m on the 750mm rail kit, 611 router. I’m up for a project if some diy upgrades will improve the machine. Thanks!
