Looks like the ELS is a fantastic success. Congratulations!

Still have a bit to do to package everything up, but first chips really made my day! Especially since it just worked, save for cutting LH threads initially. Since my G0752Z never could do LH threads (without adding an idler) I am happy to now have that ability.

The packaging for me is the hardest part - stuffing everything in a box, power inputs, switches, etc, getting it bullet proof, exposing the touchscreen, installing the display bezel and making it look ok. Probably a month or two more work. Right now it looks like a Rube Goldberg contraption with flying wires and little boards wired together. Not really fit for shop use as all the electronics are exposed. Basically, everything needs to be buttoned up.
 
Great you got the ELS working so well. Thinking I would like to do that setup on my 1891, 22" lathe. Would just need to scale things up a bit. Mike

Probably the stepper, it's driver and power supply. I'm using a NEMA 24 4Nm closed loop stepper system. You will need to go larger! The motors, drivers and power supply are the lion share of the cost of the system.

Honestly, the toughest part for me was the touchscreen display software development. But I made a series of hand drawn cartoons how I wanted the screens to look and progess. That got me through that part. There's about 3x more code in the display and touchscreen section than in the motor control section. However, I find the navigation and use very simple because I thought that section through. I don't have tactile feedback, but there's visual feedback of the button presses. The display changes to show your selection and every screen has a way to back out to the previous one. Could use some refining, but pretty pleased with it as is.

Got tired of sliding the magnet on my Loc-Line Chip Shield across the ways of my lathe, so changed it for a large Shars base; also added a second 90 and 6 more fittings for more flexibility:

I admit that I don't use it often as flying chips aren't an issue with most of the materials I use, but when I shortened an alloy set screw recently the hot chips were everywhere:

When I got the extra fittings I also picked up a set of assembly pliers (not absolutely necessary, but makes putting the 3/4" fittings together a lot easier):

Today i had couple of brake discs to turn on my lathe, this the 3rd set this week. It seams parts shortages have the mechanics having to do this rather than replaced parts.. I also bought me some R134a freon for the next season. The price is more than double than last year, 265 euro for a 13,6 kg cylinder now.

Have some work coming up in my business for some barn board mill work. I didn’t want to use my good saw blades to rip boards with the chance of nails. . I have a bunch of 16” blades that someone gave me, but the Center hole needs to be 30 mm not 1“ to fit on my saw. So I bored them out.
