For the spindle a KBSI-240D will do the job.

FWIW, I have skimmed through most of the 403 page Lathe user manual and when I look up G99 there is nothing anywhere that says nothing will happen if it's active and the spindle isn't turning. If the spindle is turning, I am now getting movement so thanks for the tip. But is it possible to command ...

You should read the manual....

G98 per minute feed
G99 per revolution feed

if G99 is active and the spindle is not turning nothing will happen

Looks like a mechanical problem, backlash or something else not tight.

G91 is for mills, not for lathes

There is a pro version of the plugin for 4-5 axis machining, you can send an inquiry if he could make a multiaxis version for lathes.

If 1111.nc is loaded and you replace this file with a new version 1111.nc just hit cycle start.

No need to load it again.

If the new job with same name is placed in the same location as the current job, CNC12 will execute the new job.

I do not think the driver accepts 0-10V for rpm control from Acorn. A CNC with only spindle on/off is not the best idea. Also, If you want to use rigid tapping, feed/rev an encoder 1:1 on the spindle is required. For the size of this lathe, a 1500W AC Servo with 0-3000 rpm would be a better choice. ...

They work, there are lot of low buck conversions with these, but I think 340$ for the other parts is too much.

I would use a JMC or Leadshine servo and make the adaption my self.
