Thanks for replying Gerry,

That would be a good figure to aim for I guess, at least for rapid traverse/homing situations. I will only be cutting wood and plastics (with maybe some PCB material) and will need a 'reasonable' feed rate to prevent burning of the parts/cutters. I will be using a laminate router (20,000 RPM) with 1/4" and 1/8" collets and the largest cutter I have with a 1/4" shank is 1/2" diameter. The smallest cutters will be tiny carbide PCB type drills/mills and engraving bits. The router is being wired through a speed control too so that I can adjust spindle speed as well as feedrate.

If you wait long enough, you should be able to get one for around $10-$20. And you really need bigger motors, preferably at least 200 oz-in. You can get these 166oz-in for $29 from http://web6.automationdirect.com/adc.../STP-MTR-23055
And if you still can't get enough speed, you need to switch to something like 1/2-10 acme. |
Yup that's what I thought I was going to have to do but I thought I would ask first before making another costly mistake :frown: . The really frustrating part is the hours I spent researching all the different options in terms of motors, drivers, power supplies etc. and I still messed up!

Neither do I. Ho hum, time to make some changes I guess.
