I have SprutCAM pretty well licked for carving foam with my Kuka KR30/2; it may be an older 'bot, but I'm very happy with the results so far...but now I have to figure out what kind of spindle to use if I want to use a ballnose bit that is 8" long and 1/2" in diameter. I tried using it on my Hitachi woodworking router, but after only 20 minutes the motor felt very, very, VERY hot, so I have to find a better, heavier-duty solution.
My robot has a 30 kg payload limit. What kind of spindles are other people out there using for this type of work?i'd really like to get to an ER32 collet size so I can use 3/4 diameter bits.....but at this point I could live with a limit of ER20 (1/2")
Thanks for any replies!
