Pimping the mini-lathe

Episode 19 is now up...


Happy fathers day.

Hi Mark - it's amazing how much work you're putting it this small lathe, and I love the IKEA shelves idea.

Look forward to see movement, now that we're moving to the CNC part!

Will you be reutilizing the acetal ballscrew mounts, or are we in for a Maho threadmilling video soon?

Pierre

Hi Pierre,

Glad you joined. For others, Pierre, another guy and I met through the internet back in 2003, when we all wanted to CNC our mini-lathes. Since they both had CNC'd mills, they made the parts and I did the CAD work.

I switched from the Nylatron Z axis nut on Trapezoid lead screw, to a cheap rolled ball screw at some point. It is an Imperial lead ball screw, with more back lash than the lead screw it replaced, but has lower friction and allowed higher speeds. I am pretty sure the cheap generic chinese lead screws you can buy with end machining from Ebay or Ali are higher quality. I should look into that.

Another thread milling video???

I just uploaded episode 20 to youtube.

Good to know. Thanks. This VFD is ancient, and seems to only support 0-10vdc control or a potentiometer, so that €10 widget seemed the easiest solution I could find.

I should have my little NUC powered up today. I remember that it was a PITA to get it to boot from USB. I had to dick around in some UEFI settings I didn't understand. I got it to boot more by luck than by skill, and now have the standard LinuxCNC 2.7 image on it.

I understand that need to both upgrade this to 2.8 and alter the Linux Kernal to replace RTAI with Preempt_rt for the 7i96 driver to work.

Peter (Talla83) has an excellent video on how to do a clean install, but I was wondering if I can use APT-GET or SPM to make the changes to the existing install?
