click on the link in my sig, then add "lathe-stf" to the address bar and hit return, then click on "linuxcnc4rpi4". There you will find a README that should tell you how to install the preempt-rt kernel thats also there, and the debs for LinuxCNC, a sample jpeg screenshot showing what it looks like on my screen, and the config that runs a cnc converted Sheldon 11x54 lathe here. I started out with an rpi3b for about 3 years but it was a wee bit overworked, but the rpi4b only has to be pushed to 800 MHz to do it very well. Because the interface card I used had gpio to throw away, quite a bit of control gingerbread has been added, like a pair of 100 ppr hand dials replacing the original hand cranks, and all the lathes power is controlled by LinuxCNC, so when I walk away it draws about 15 watts. Since LCNC is a better compound that a real one, there isn't one on the lathe. Bed wear on a 70 yo machine has been measured and compensated for by LinuxCNC, and for rigid tapping, the turn around overshoot at the bottom of a hole is measured and displayed so you can cut air for a reading, then substract that in your code, thereby stopping short of running into the bottom of a hole and breaking a $30 tap off in the hole, and that not only costs money but takes a day to remove the broken tap (w/o damaging the threads) with an EDM setup.
