Greetings! I'd be curious to know how you handle odd-numbers of divisions. Here is a link to my attempt 4 years ago: I'm afraid that when you work directly from the stepper, the odd number steps won't come out quite right ( like the problem dividing plates solve for a traditional dividing...

Yes - the project is a tad old! I've gotten off into a number of other things and had to put that on the back burner. I can give you the Arduino source (but it may be a bit obscure!) If you are interested in giving it a go I'll be glad to help out as I can. One of the big probs I see with this...

Here is a link to yet another take on creating an indexer with an arduino: The concept needs a bit of refinement for real accuracy on odd-tooth spacing but I have an idea for that... when I get my 'round-2-it' !

Recently I added a WEN 4214 drill press to my shop, but was VERY disappointed at the mechanical variable speed. While it did work, and nicely built, it was as noisy as a rock crusher and a bit inconvenient to use. So after much YouTube and forum research, I came up with plan to use a DC motor...

Here is a link to yet another version of an Arduino based index head I have a little different "user interface" - the way of entering the steps, degrees and such. I'd like to hear/see how yours performs under the mill... I'm haven't fully tested mine yet and am wondering if the steppers will...

Swarf is def getting ahead of me - but I generally cut dry - or just a tiny brush of WD-40 or such. But I really didn't quite have a good image of how bad the swarf would fly around... especially the AL.

Yeah - My most-used tool is the shop-vac, but the AL chips are getting ahead of me - they do tend to get tramped in. I do need to set up some swarf-guards around the machines as annoying as they are. I've also thought of just removing the carpet in this room... it is 10 yrs old... maybe put...

Todd - not so bad really. $500, and you would pay $200 for "ok" caliper-style scales, and only get the position info. And you would still have to go thru the mounting process... So I figured why not get the better scales, AND the cool DRO capability. Check my site for a link to the eBay seller.

Greets to all! Just completed adding a set of Sinpo glass scales and DRO to my Little Machine Shop 3960 mill (a deluxe X2). This may be considered a bit of overkill for a small machine like this - but the JCXF series scales are small enough to tuck right in and be almost un-noticed. And the...

I think this can be set up on a CNC lathe. Cutting threads is just a matter of having the cutter traverse the workpiece at some rate ( pitch). Gear driven lead screws are limited by the ratios available in the change gears. When the LS is driven by a computer controlled stepper motor, any pitch...
