Happy New Years, my friends.

I've already lit the drinking lamp as I get to have an early start on new years eve this year. 

Sometimes you just have to say F%^& -it once in awhile 

That's a beautiful friend you have, Ed.

Cheers, all-

I have stayed away from anything else running in the background as it only robs the resources from Mach 3 which is a recource hog to begin with.

I've heard the smoothstepper eases this a great deal but if you're using parallel port, it's russian roulette in my eyes -

Well thank you, Glenn, I appreciate that.

I'm such a sucker for pictures and I guess that's why I like to take so many.

I just had a look at you steps/deg calculation and I think there may be an error.

Wiith 1.8deg stepper it is 200 steps per 360 deg. With micro stepping it should be 2000 steps per 360 deg or 5.55555steps/deg

C

Thanks for looking, but with the 72:1 ratio, doesn't that come into play with the angular measurement?

Thanks,
Dave

I have no experience of 4th axis but would have thought if you have your steps per set correctly then just putting a clock on some convenient part of the axis and then rotating by step mode in mach one way, not the clock reading and zero the DRO then step back until the clock moves and read off the DRO in Mach.

Edit, BTW a clock is what we call a dial indicator here, just in case you USA guys dont call it that

Yes, Hood, now that I can be sure of the steps, that should work, I would think.

As for clocks, we use those to tell time in the shop, not to measure the things that take time in the shop.....

Thanks, Bill, and yes, no gear reduction at all. You can see it here:

As for the backlash measurement. When I have the flatbar clamped to the table and the indicator at the far end of the bar, what am I looking for to determine the backplash.

Is the PDF I'm including in this post the formula I'll need to use?

CT,

I'd be interested in seeing the list of items you used as I'm shopping around for a better setup for my Taig Lathe conversion -
