That's actually pretty impressive for 20 threads per inch screws. On the old V90s, we were getting 200 IPM, but we were using high dollar acme screws that only took 5 turns to move an inch. Our current machines can run 400IPM with two revs per inch screws on 570ozin motors.

The older lead screws were off-the-shelf Roton parts. We use off-the-shelf parts so that they are never obsolete. Here is where to find the part numbers:

If we were still in Illinois, we'd be there. But we are in Florida, now. If you are close, I'd highly recommend it, though.

It would be easy to do on our machines. You would need to wire it into the second parallel port and connect it to the probe-in signal in the software configuration.

There are several links to more info and some sample g-code routines here:

Awesome!

It was whatever mini-itx motherboard we were able to get at the time that gave the best performance with LinuxCNC. PCs change so rapidly I couldnt tell you any more than that. And that would be the point I would make with the buyer is that we hand picked those parts to guarantee performance. If it r...

I have talked to the LinuxCNC guys at length about the issue, and I have to agree with their assessment. When A is included in a line of g-code, then Feed has to be in degrees. Its not the job of the controller to do anything other than execute g-code, and the only way it could do Feed in IPM for a ...

Hey Lyman! I sent you an email asking about this, but never heard back. Everything okay with you?

There is an option in the new configurator to run the machine with soft-limits only. They still work as home switches during homing, but then are disabled until you have to home the machine again.

Post a list of all of the G codes listed in the list of active g-codes. Be exact.
