Indexer info needed

[tom_fiddler]

So I just upgraded my 2005 PRT Alfa 96 x48 to the 7.2 drives.

Can I use the old drives and motors to run an indexer?
I have found a wood lathe to convert to a belt drive for the steppers.
I have an opportunity to make some gun stocks for a guy who makes repro black powder guns.

I have made a lot of strange stuff on my bot and have always wanted an indexer.

On the software side I just got V Carve pro. Should I upgrade to Aspire? or is there a cheaper choice to get the most from the indexer.

Thanks

Found most of the info needed already on the forum.
Ordered lathe today
Let the fun begin!

you still need a stepper motor (indexer motor) and not just a lathe. Previously you could insert a lathe if you wanted constant A/B axis movement while x,y,z moved but with the new software upgrade that eliminates the need for the lathe. Unless you need a faster spin to do things like sanding parts.

Thanks Jack
I am going to add the stepper motor to the lathe I ordered. With a belt reduction.
Since I have the direct drive steppers left over from my 7.2 upgrade, I will be shooting for a 10 : 1 reduction.

Also has anyone used their indexer for 3-d scanning?
I was thinking along the lines of mounting the scanning cameras on the Y car and then having the Shop bot slowly turn the indexer as the Y car moved across the part.

Thanks

Not much love for the indexers here...lol

Lathe came today. Had to cut on it a bit for it to fit. Got the B axis worked out and will order belts and pulleys Monday.

Made some air cuts today (just watching the B axis) and it seems to be working correctly.

Long way to go but getting there. I LIKE IT !!

Tom,
Soon we will expect you to do something like this.....

If you need some help or questions on how to make some of this let me know.

[tom_fiddler]

Piece of cake........NOT

Once I get it working I am sure I will be in touch.

That is a neat piece.

Thanks

Got my pulleys and belts (one spare) ordered today.
I will start off at 3.6 or 4.0 :1 ratio , Depending if I can machine the smaller of the drive pulleys to fit.

The plan is to possibly move up to 10:1 ratio after I get the indexer working and cut a larger driven gear out of plastic or G-10.

The new lathe was here about 15 minutes before I took the "Death Wheel" to it.

Got the pulleys today.
I was able to sneak in the 14mm bore in the 18 tooth pulley.
72 Driven pulley gives me 4:1 ratio.
