Trying to set up stepconf...

I got a little mill a few years ago, just a little Zenbot Mini, and used to run it on a different controller program. It was a trial version, though, with limitations. I recently switched a computer to linux, and wondered if there was a linux alternative to that program. I was happy to find LinuxCNC!

I'm trying to run through the stepconf wizard, but I am having a little bit of trouble. I was able to use the Xylotex defaults for most of it, but when it comes to configuring the axes, I am at a loss. I have the documentation for the Zenbot Mini, and it says this:

"The drive pulley diameter on this machine is 11.6 mm or .45669 inches. The circumference of the drive pulley is 1.4347. This means that the motor rotates .69701 turns per inch (1/1.4347). The stepper motors on this machine are a standard 1.8 degree per step motor, which means that there are 200 steps per revolution. Now you just need to know the micro-step settings on your drivers. The formula for calculating the steps per inch is .69701 x 200 x micro-steps/step. For a 1/8 micro-step driver, the formula would be .69701 x 200 x 8 = 1115.216 steps per inch."

Then it gives a table showing the proper steps per inch for various microstepping settings.

The Leadscrew Pitch option says rev/in, so it seems that would just be .69701, wouldn't it? I entered that, and a drive microstepping of 2, and the Axis SCALE readout says 278.8 steps/inch, which is what the manual for the mill said it should be. "Eureka!" I thought. But no. An entry of x1 y1 moves the machine almost exactly 1/4 of an inch.

I feel like I am missing something very simple here, but I just can't imagine what it is. I've never been all that great with math, but had no trouble setting this up last time. If anyone can help I'd be grateful!

If you need any more information, just ask. I don't know much about the machine, only what is in the manual.

I'll try that when I get home from work.
Thanks for the quick reply!

Set my microstepping to 8, and got the 1115.2 I was looking for. Works great. Thanks again!
