Forward Step / Backward Step - Vexta Question

@Hi Brenda,

For your motor scaling, you can use following example, if your drive is up to 10000 you know what to change :

## Calculation ##
# drive : 5000 steps / rev
# pitch : 4 mm / rev
# calcutation : 5000 / 4 =
# scale = 1250

The stepconfig wizzard is very confusing to me. So this formula makes it very simple to handle.

Thank you.

I used a Arduino utility I wrote RDL to test my calculations each axis as I was building the machine. It gets tiresome turning ballscrews by hand.

I post this thing here and there, because I thought that people could sort out a lot before they come here and ask a lot of noob questions like I have.

Without microstepping 2 of my machine's axis resolution is limited to .02mm, with microstepping on it would be .01mm. Accuracy may vary. 10mm screw, .72deg motors (500 steps).

BTW, is the HAL I am using for Forward Step / Backward Step (Vexta) So Far.

Todo: Limit switch issues. They are being read, and home, almost. Could be bouncing, could have been the options I chose whilst running Stepconf.

I shot a small jogging video.

I will put more some videos on Youtube, but like many people youtube ripped me off for adsense, so I'm not too happy with them right now.

For now, I am only using 100 for acceleration because the cart needs to be immobilized. I think the motors will go faster, but this is fast enough to learn how to crash a CNC machine, and send milling bit shrapnel across the garage.

Oddly, the machine looks bigger in person. The frame 4 feet wide and 5 feet long. The work envelope will be 910mm x 1100 x 120mm ( 35" wide x 43" long x 4.5" high ) The weight is about dontwannadroponme, or perhaps just under 250 lbs.

Thanks everyone : )
