>From the top bar of a running instance, axis-lathe.ngc AXIS 2.8.0-pre1-2758-g1bcd51e on HM2_rpspi-stepper This particular config, from the examples choice if you just run linuxcnc so it opens the menu to ask what config, axis-lathe.ngc, is actually a 3 axis simple milling machine, so that its what I chose to copy to the configs directory, and now I am trying to actually make it for a 2 axis lathe. I'd call that an in need of fixing bug. :) I can add to it as things get hooked up. I've got the vfd working, thanks Peter for the SpinX1's I bought, tried, a did something different to TLM eventually, but it seems the SpinX1 was designed for exactly this job, running a vfd. I do need to insert some scaling though, an s245 m3 gets me 15 hz to the motor. If it has enough torque at that speed to move the lathe is yet TBD. I don't have very much slow boost, 0.4 IIRC, starting to kick in at 45 Hz. So it will sit there on the table at 450 rpm without any signs of overheating. But pulling the lathe? At that speed an m3-m4-m3 is perhaps 1/2 second. With the belts in low gear, and the backgear engaged, that ought to be about 75 revs at the chuck. But I've not cobbled up a chuck lock yet either. Its a screw on chuck, and heavy for me to handle. The spindles seating flange is only about 1/4" thick, so I should drill lock pin holes more than 1/8" in diameter, so I am thinking two screws, 180 degrees apart, in a circle of 1/2" thick 7075T6 surrounding the backing plates hub, with the holes 1/8" deep, and a pair of 6mm screws with their noses turned to 1/8" for about 3/16" so they would lock in the bottoms of the holes. Thinking of putting a 1.5" square tubing frame on the back of the chip pan, cutting the legs to 41.5" and the top crossbar however long the bed is, 50 something inches, with the monitor on a $15 swing mount on the front of the left leg, this computer/driver box I am building up on the back of that same leg, a 4 foot led shop light on tabs to extend it fwd a bit. and some sort of a concoction to hold often used tools like the chuck wench, etc on the right post, getting that stuff up out of the drawers and chip pan. But I measured the steel I have, and found I'll need to source another 10 foot stick of it before I start pushing a hack saw or dragging out my mig welder. I have yet to figure a place for the vfd itself, but thinking about sticking it on the motor housing leg of the "desk" under the left drawer. I'd have to write a bunch of hal stuff to be able to program in remotely as opposed to me getting into a position where I could run its panel buttons. I could get there, but I'd likely need help getting back vertical. Its got to be well protected from flying swarf, yet have enough cooling air And that position would/should be relatively safe. I just heard the little mail van putter by so I'd better go see what he brought me to play with today. A 5 amp 5 volt supply & some other toys I hope. I'll check back in to see how I complete the file sanitizing in a couple hours. Thank you Andy.
