That would be a good idea on a gantry-style CNC router, capable of much higher feedrates than the Maslow. We’re currently limited to about 1000mm/min, which seriously affects tooling choices. For example, if you used a 1/2" two-flute bit, you would need to be running the spindle around 2,500rpm in order to not burn out bits. Given that the default router for this project, the Rigid R2200, has a minimum speed of 10,000rpm, it’s forced our hands on tooling. I would like to try to use a CNC spindle with a VFD at some point to get those lower RPM’s needed for larger tooling. Alternatively, you could use a super PID to control the Rigid router’s speed.
That’s the thought. I know @Bryan_Pollock has used one on his machine and gotten pretty good results. We talked about the tool in this thread a little while back. I’ve been watching the price fluctuate on Amazon, but it’s been staying around $60 US for a few weeks, so I might just bite the bullet and buy it at that price.
