I am trying to figure out the best way to get contrast out of a stained wood engraving. My original plan was to stain a piece of wood fairly dark using Ebony colored stain. Then engrave it on my CNC....

I have seen that graph you linked. Problem is there are no units so I don't know if that performance increase is to scale.

I'm basing that 24V rating on what I remember the datasheet says for...

Thanks for the reply Gerry. We have received a big education over the last couple of days. I see now that you are right when you say we did it all wrong. I'd like to say I wish we knew all that...

So it seems we basically picked the worst possible way to wire our motors for our machine. We don't need more torque we need speed. I wonder now if our original motors would have worked. Oh well...

They are Bipolar-Series. Would having only 24V really limit our speed to such a low number? That surprises me given the popularity of the Toshiba drivers. I've been looking at the calculators here. I...

We recently upgraded our DIY machine from 170 oz/in motors to 425 oz/in motors. With the lower torque motors we could not get the ipm speed nessecary to cut wood (80 - 110 ipm). Thinking that our...
