Cool deal.

The majority of my jobs will be cutting about 1/8th" deep slots in Copper so speed of z doesnt bother me much ..
More time to sip a beer !!!   lol

I'll have to see if I can find one ..
I have a few 460 Ouncers if torque is an issue  ;D
Doubt it will though . you can turn that micro feed knob with your pinkie.

Calculator time !!!

I have a 2 to one ratio between the motor and shaft.
then god only knows the ratio between the shaft rotation and one inch of travel.
Sounds like a cold beer and measurement night is in store !!!  lol

This is what Im eventually gonna make

Hey guys.
I finally mounted the z axis stepper on my Mill/Drill.
As it's a temp solution because I eventually will use a servo I just mounted it on
the side of the head with a belt going to the Micro feed knob on the mill.
Heres the issue.
Its a 140 OZ stepper as hardly any tourque is needed to turn that wheel.
its a 200 step per rev motor.
I tried to auto calibrate it like I did with my X&Y servo's but that dont float !!!
I set it to move 2 inches .. it moved like a 1/8 Inch so Mach set it to 10,000 steps per !!!  LOL
That little puppy doesnt have a chance !!!

How can I calibrate a stepper to move an Inch when I want it to move an inch ???

Is the problem that Im using the micro feed spindle adjustment ??
The step down ratio must be huge . When I jog up and down its pretty dang slow.
I can deal with Slow I just want it to be acurate as far as movement measure.
Any idea's ??

Sure does .
I suppose I need to reroute some cables .
I have a heavy duty Earth ground cable grounding everything , PC, Controllers and Mill.
But I suppose a power cable could be giving me some induction issues.

Bill,
Thats how mine acted too.
Im running a 3 Ghz with 1 gig memory.
It would calibrate distance smooth as silk , even Jog smooth.
But when I would home it would stop after a few inches.
Had me befuddled   :)
Set the debounce and all is Gravy now !!
Brian , can you explain in "Noobie" terms why that would be ?
Homing moves much slower , thats the only diff I noticed.
