It doesn't really matter how the chips get to the floor.
both methods can make quite a mess if mixed with inexperience.
both methods require quite a bit of effort.

does any one know what would happen if a 1200oz/in motor rated for 3.4A was run on only 2A?
if the loss in power means the torque would drop to 600 or 700 oz/in that's still not a small amount of...

I have an old radial arm saw that basically has the 2 extra axis -turns around 360 & drops through 180. It could be used as the spindle motor. but its not small and would need a large strong gantry...

yes nice logic but as they say ... the best laid plans... And I have had issues due to miss judgement and other unforseen. An encoder would be the simplest form of reset / feedback control method.

I have no answer for u but I am also interested in exactly this. maybe if two seek they shall find

Ive got an old radial arm saw on which the saw will turn 180 deg in Z and 180 in Y.

I have dreams of suspending it from a gantry.
have to sort out motor placement etc..

these must be findable...

I got it to work hooray.

I've moved the controllers and power supply as far apart as the exsisting wires would reach ( without adding any shielding) and now it works. It follows mach 2 paths as...

Not yet,I will try that tonight.

The man who sold me the controllers freaked out about using unipolar motors with a bipolar drive. has any one got thoughts on this?

Thanks for the interest.

the power supply is 24v 150w
the controllers are L297 - 298 capable of 36v
I have not come across a 36v supply and wouldn't know how to modify the exsisting situation.

I have bought and assembled 3 x chopper driver boards with half step function and 3 x 222oz/in 0.6a motors, and a ppt breakout board

have not hooked it up to any machine yet.

Hi from Brunswick Vic,

Ive been watching, reading and following links. I think Jgro's design will be a good starting point for me.
I make furniture and want to build an efficiency tool.
