If you have the broken part it would be easy to get someone local to cast one in aluminum or brass. Your local community college or tech college would love to do it as a project.
Or you could just...
Gerry,
I think I'll stick with the 10TPI for now, just to get some experience with the machine and then I can upgrade to what makes sense at that time.
I did think about using a 2:1 gear set-up...
Ah well, back to the drawing board to see what I can do.
thanks for all the help,
I'll let you know how I get on.

Well, if I can get 500-600 IPM out of my current lead-screws with the right motors I would say no.

Gerry,
Re. lead-screws, at this point I would say yes unless there is a really compelling reason to switch.

Gerry, and anyone who wants to join in...
You proposed an upgrade to the system using a Geckodrive 540. My router is set up to have travels as follows: x=46: y=22" and Z = 15". I have checked torque...
Continuing my learning saga, I tried the pulse width increase and it works. Thanks for the suggestion. I ended up with a 10 microsecond pulse width and that seems to have cured the problem....

First, thanks for the help,it's really appreciated, just having someone else to bounce ideas around is great.
Some progress in isolating the issue:
I disconnected the motors from the...
Gerry,
Half or Full stepping? I don't know, I'll have to dig into the Stepperworld documents. Can I change Mach3 from one to another to test?
Lead screws are ACME 5/8" X 10 TPI single thread,...
More data:
Checked for slippage using two pointers, one on the motor end shaft and one on the lead screw, I couldn't see any slippage.
I tried varying the drive speed of the motor using Mach3...
Gerry,
I certainly agree on the ruling out one thing at a time.
Thanks, yes I thought about slippage, I have changed the hose/clamp connectors to a softer rubber and there doesn't seem to be any...
I'm a beginner to CNC and so far I have progressed to having my router up and running in a fashion.
It's a home built wood frame machine with skate board bearings on aluminum tracks for each axis,...

I'm a retired engineer, now into woodworking and RC model airplanes. (I've lots of posts in the RCGroups equivalent to this forum.)
Just getting into CNC, and planning to...
