I'm gagging to upgrade my spindle, I've got money just no options

Yep. It works well. I dont use my ATC often but functionally it works. I can do some improvements to it for fine tuning but the machine is now running at minimum as good as it would have when new.

Where are you based? You are welcome to come look at the bits.

So spindle speed? How have you got it to work?

What kind of setup?

The triac has a slightly different atc seti
Up the. Most with its spindle and powered draw bar

I'm in Essex?

Direct motor replacement, 4400 rpm due to slight change in gearing.

Im in West London - UB108TE, feel free to pop around, Im home Saturday if you want to see my mess.

Ill take some pics anyways to share.

What did you end up with an m6 macro for the atc? Any chance you could post it up?

Not knocking ya build or anything but triac comes with a 4000rpm motor so that's not really an upgrade.

I want to min of 10000rpm

What electronics do you have? I'm assuming your running mach?

I have full drawings to upgrade the atc to 10 tools just never got round to making it. It's just a new disk/bit that holds the tools and stepper motor to spin the disk

It wasnt meant as an upgrade. It was meant to get me up and running again. The DC motor was failing and I had to make do with something as I am using the Triac to make parts for my new machine.

10K is possible, of course, but its a fairly big undertaken and not a 'hot swap' like what I did.

I am running with CS Labs - Mach 3 - Servos all round for all axis.

ah fair enough, ive had issues with my motor and still do to be fair.

I put mine in for a £500 repair which hasn't really done a lot, so wondering if its the sprint drive card.

indeed 10k is possible its just finding a suitable replacement atc motor. id settle for 18k or 24k providing its an atc model.

mines a standard triac, so normal stepper motors, ive got PMDX126 in there, with ESS. I out in spindle feed back and have touch probe and z height setter wired in.

but my goal is a new atc spindle and then ill finish the electronics with new stepper drivers and out 10 station atc in

I had an initial bit of code provided however it did not work. My code is poor and doesnt care for the status of limit switches or even counting of the ATC. It does however work so can post.

Im selling my Sprint 1220i controller if you need a replacement.
