I am glad you mentioned that. I will just keep my little 300w spindle at a comfortable 30 ipm.
I do actually have a Dewalt 611 router that I purchased long before I ever heard of Inventables. But I have not tried to attach it to the X-Carve mainly because I really like the ER11 collet. I am able to easily use 1/4, 1/8, 6mm, 4mm shank size bits with no trouble. The last time I looked a 1/4 inch collet for the Dewalt was crazy expensive and a pain to swap out (compared to the ER11).
I also really like the very nice barrel type mount for the 300w spindle. I originally was using the ring type holders with the SO2 and keeping everything aligned was a real pain.
What has been your experience with the Dewalt collet and mounting system?
