Personally I think 150 direct drive is not enough for that mill, In my case I'm using 200+ geared 2:1 servos. I also converted everything to ball screw.
I'm converting a HF mill mini to cnc.
However I'm a complete newb when it comes to the electronics. I've tried to read some of the white papers, but honestly I'm completely lost.
I need a step by step guide to what I need.
I plan on using a nema 23 size steppers.
I'd like to have minimal of 150oz, but would not be opposed to smaller. Assuming the drivers could handle the upgrade later.
I'm not 100% sure if I should be uni or bipolar. I don't know the benefits or limitations of them.
Cost is an issue, but not a terrible one. ((I'd like to have a full list of parts, so there are no "gotchas" later.))
A decent feed rate would be nice, but this is for prototyping in aluminum.
I'm fairly decent with a soldiering iron and can follow a wiring schematic. However a pretested board may be better for the initial run.
So I need a driver board(s) with or without lpt breakout, board/motor wiring, power supply, motors?
I'm slowly starting to get a grasp on what is needed/suggested, but any help would be great.
Hmm, I considered using a ratio to motor, and may end up that way.
Right now, I'm just at the point where I'd like to see the mill do more than pick up dust.
Currently looking at the Tamagawa 282 Oz Steppers off ebay, but in all honestly. I'm just wandering around blindly. (grins)
