Thanks for getting that fixed up for me. I added ball bearings on
either side of the lower belt to tension it. I just used the same
mounting holes from the step motor and it tightened up nicely.
The single screw holding the D-rod shaft came loose and had to be
tightened, so that's not the

Tim, I'm running my X and Y at 50ipm and the Z and A at 20ipm; I hope
that's the right way to say it. The Z axis has been working great
today, so maybe I just found it's sweet spot.
Steve, I was going to go with limit switches when the time comes, but
I honestly don't know that I'll add them if

Are you going to install limit switches or use software limits in
Mach?
I have a 900/Standard and added fuses to each motor. I also want to
add limit switches. Still a ways from there as I need time to dig in
and time is pretty short. Let me know if you want to see what a stock

Hey Tim, thanks for your continued interest.
I got to work on my electronics, but made an error in soldering one of
my cables. Some solder got between two pins on one of my DB9
connections and blew out my G540 controller. I sent it back to
Geckodrives and they told me that repairs were free,
Another observation, you might want to take off your depth stop on your z-axis
so an accident does not happen :-).

How did you couple the motor to the legacy drive spindle? I am playing with
something like your idea here ,but not on the CNC side of this scale.
Did you make a coupler to fit over the notches of the spindle drive or did you
just tap into the screw insert and us a jam nut?
Nice job, Im
Pro's of the direct drive is no backlash. My concern is lack of power. That's
why most people have timing belts or gearheads (gear heads designed to work
with stepper motors) I believe legacy's first cnc version used laser cut gears
and I'm sure that was a source of backlash. Their latest
I don't think you will have enough torque with the 1:1 ratio on the A axis.
On the Joe's Hybrid CNC I built with Burney we used a 1200 oz/inch motor
with a 3:1 ratio. On the Legacy that we CNCed we used a 620 oz/inch with a
3:1 ratio and it wasn't enough.

I knew the Artisans used a gear head and that's the best way to go in my
opinion. I'm really curious what is behind the cover of the arty and mini

With the cnc up grade to my 1500 the gear from the motor had about 24 teeth,
the other gear had about 97, so you are looking at about a 4 to 1 ratio

Thanks all for all the advice on the gears and stepper sizes and
practical advice in general. I'm worried about stalling too, which is
why I tried to be as minimal as possible with the physical changes to
the Legacy in case it does not work out.
At any rate, hopefully I'll be able to get

Keep up with the good work.
looking forward to hearing how it works out.
Good luck.

Photos of Y and Z axis
I think I would not increase the friction on the opposite side of the lead
screw. Leave that to float. If the round bushings on the rails are not
touching the top and bottom of the groove, I'd be willing to bet they have
divots in them. You might want to rotate them to a new spot fresh spot.
When slaving A to X, I suspect that your problem is that both motors are
turning the same direction. One should turn clockwise and the other counter
clockwise. You built one CNC router why not build an indexer from scratch
with the strength needed for the job.

I had the problem on the Y-axis as well. I'd try and jog one direction
then back and sometimes it would continue on in the same direction.
That's why I thought it may have been a cabling/parallel port
problem.
Also, I'd be willing to try to rebuild from scratch; I didn't find the
construction
Here is a starting point.

I have to chuckle because your story is like so many people that have made
the trek down cnc lane. It was a good idea but some details got in the way
and the parts got put on a shelf but the desire never went away. Look at
it this way, your not reinventing the wheel, but perfecting the cnc
