Forgot to add, I tested the same setup with a UNO, only difference was the I2C pins on the UNO were in a different location. All the rest were the same pin #'s. No changes to the code provided.

lol this pisses me off, a bunch of the ebay sellers i have been buying from are saying us stock, providing a tracking number, waiting for the item to get to them from china then shipping it out. actually had one that came straight from china the other day....

so my new 6600 got here, its not a 6600 tho, at least it truly shipped from california.....
i figured out that having the enable ground wire connected at all was stopping it from rotating on the B button, but now that i fixed that it still only moves one direction.
i have ordered all of the parts to build a 2nd controller sense its cheap.
i compared the script im using with the original 2016 script in context and there is nothing i see that would cause this there.
not looking for help or advice right now, just giving an update.
ill post the status again when i get the 2nd controller built for testing.

Finally got my setup to go in both directions, however the motor after doing a revolution in either direction starts to slowly creep a little then becomes faster. Only way to stop it is by pressing the reset button.
Seems to be a possible problem with either the lcd shield or the motor driver. Has anyone else encountered this problem?

have not had that happen to me, my lcd is not a shield tho, i decided to go with the separate lcd and keypad for more inputs and compartmentalized problems.
did you try the code for simple forward and back that fooser posted for me on page 15 of this thread ?
it does not use any of the lcd or touch pad
stuff and lets you test the driver and motor with the board only.

There are many programs that enable you to compare different versions of code (text).thanks Scott, that will definitely help a lotabit, i wont have to count arrows down to 276 againbut i still want those good old compare script and search features
I use winmerge from http://winmerge.org/
is that an all in one with arduino also ? i have context thats what i was used to using 15 years ago, i was just hoping to use a single program for all of it

No, just a simple standalone program. Quite powerful though.

Sort of working. Got both directions working but after a complete revolution the stepper stafts to creep.

Although have tried that in the past with no problems I will try again just to be sure.
Here's some pictures of the dividing head. I've hooked it up to the arduino and it works. More than enough torque and holding power using the NEMA 23 motor. The ratio of the timing pulleys is 12 : 60 or 1:5.
The spindle is an ER20 with a 3/4" shaft running in sealed ball bearings.

I think something is wrong, if you have a gear in the motor with 12 teeth an another with 60 teeth the ratio is 5:1 when gear with 12 teeth spins 5 times gear with 60 teeth will spins one time.
Have you read revwarguy's Arduino Indexing (Dividing) Head article?
Very well done and inculdes a link to the arduino software.

I realize that this is an old thread, BUT...
I'm in the process of making an indexer for my Mini Lathe, and I have looked at many, but I really like the simplicity of Alan R's (AKA harrzack) solution in post #263. There he shows a video of a very clean simple method of controlling stepped rotation. But, as he mentions below, his website was hacked and no longer has the files available.
So... my question is: does anyone have, or know where I can obtain the schematic & Arduino code for his project, OR does someone know of a similar solution where I can get the information.
TIA, Muggs

The original software had some integer and error accumulation issues. By the end of the thread I believe these had all been resolved. I use my version posted in message 149. Kquiggle added in some enhancements after that.
