This one overshoots by about 10 degrees. I noticed that the last step = 763 pulses, if it started a 761 & then added one pulse to 762 19 equal times I think it would be dead on!

I did the same spreadsheet yesterday, not sure how to put that into code??

I am going to set the driver to a higher resolution and try it again, I think you are right it should reduce my accumulated error. The DM542T driver can offer as many as 25000 pulse per revolution.

Doesn't it still either calculate to 761 or 762 steps for the complete loop, putting all of the error between the first & last division? The code needs to add about 19 steps evenly divided into 16000 steps to fix the accumulated error. I don't know how to fix the code??

Do to rounding, the code sets the steps to 762, it overshoots about 19 steps at the end. the distance between each division isn't much. However, the accumulated error all ends up between the first & last gear tooth. 761 comes up short 762 comes up long.

I tried to change the grid to higher resolution, it still rounds to a given number of steps for the entire loop to 1524 steps. Actually, the accumulated error ends up equivalent to being a full hole off on a indexing plate on the last division. Gear mesh has a tight spot.

Not sure if this is the right place to join in here? I built a Arduino Indexer using the sketch listed in this post. I cut a few gears on my 40-1 index head & I thought this would make my indexing quicker & easier. The controller works great on every division that divides to a whole # from...

I have a friend that wants to know if the casting kits are still available?

Belted up to a very old grain elevator this weekend at our local antique tractor club Field Days. https://photos.app.goo.gl/G76Zh2EE6VVhEFH28

Nice day to bale hay!

Nice job! I like the base. I think I will build a mill vise next.

I just finished my Morrison & Marvin tiny vise. Incredible castings & drawings! Fun to make!

Thanks for sharing this, I think I should make one.

Mounted a removable electric motor so I can make bales without steaming up the tractor. https://photos.app.goo.gl/ym8EkMtFhXruNG4f9 Also finished the hay wagon today. The lumber is from a Black Ash tree that blew down in a storm last spring.

That's the hay press I would scale down for your 1/2 scale Lightning!

The bell tells us when it's time to drop in a board. The boards separates the bales & has guides to thread the wire through.

Ref: Bell Made my own plans, based off a photo I saw online. First I bought a replica hotel bell from eBay & designed the rest of it around the 3" dia. bell. the star wheel is 5 1/8" in diameter. The teeth are about 1/2" deep into the bale tunnel.
