Suggestions for implementing a Toolchanger countersink tool..
-
Hi guys I'm building a tool changer which will be able to insert screws. But I am also interested in creating a countersinking toolhead and wonder what the best way to implement this is. Ideally need a small sized motor. Was thinking about a brushless motor but reading some of these threads on brushless motors they may not be the easiest thing or the ideal thing to implement with Duet hardware. Any suggestions on this would be really helpful and might help others.

@Wurke do you mean a countersinking drill bit? in that case an appropriately sized DC motor (just controlled on/off) should be fine.
-
@T3P3Tony Yeah exactly. So just find one with the right RPM for cutting the material?

@Wurke For drilling operations, be aware that RRF has a minimum axis speed of 0.5mm/sec (30mm/minute), which can be too fast for drilling. This can be changed with M203 'I' parameter, see https://docs.duet3d.com/en/User_manual/Reference/Gcodes#m203-set-maximum-feedrate

Or one you can control via PWM over the range for the materials you use.
