CNC bound
finally was able to order the steppers and controllers to CNC my Mini Mill, just going to do 3 axis for now (hope to do 4 then 5 in the future)
Also ordered a copy of Howard Buckley’s book, hope to see that in a couple weeks.
Already have some good software, just need to learn how to use it 😳
once I get the mill setup and also get up to speed on the software I hope to make next gen version of my stock as well as a full air rifle 😯
(don’t really need CNC to make the air rifle, will be a nice exercise though)

got it 😀 6 feet of XPR ballscrew and 3 ballnuts
just wish it wasn’t so hot here, going to be sweating like a pig in the garage getting them in.
Going to do the Z axis first and then work on the X and Y
Awesome.
finally got an answer from those pecker-woods at Nook, my ballscrew and nuts are scheduled to be delivered today, so I hopefully will be able to post some pics after work.
Yeah I went with 4 wire.
Your suggestion is what I thought too based on the two schematics and coil digrams I checked last night and this morning – Everything matches up …. Except the email that I got from KelingInc says –
A = A
B = A-
C = B
D = B-
I dont trust that answer, so I’ve asked them to double check…..
yea I got the keling 425oz bipolars (kl23h286-20-8b)
You get the 4 wire steppers?
I got the 8 wire steppers,
I think you can think of C as A- and D as B-
but you might want to do a bit more digging
Did you get Bipolar steppers? My board schematic wants wires A, B, -A and -B… but my stepper motors wires are A, B, C and D….
sure did
Did you get the tool post grinder from LMS?
well still no ballscrews or even a tracking number 👿
but I did get my cut-off blade and post grinder, so I’m ready if I ever get my ballscrew
I believe so, usually the breakout board is opto-isolated
Shame about the ballscrews.
I’m not getting the controller boards. I see the specs for controller boards and you can hook the steppers right to them, but every one I see seems to have Breakout Boards between the stepper and the controller? Is that just to provide protection to the board or some other reason?
well it seem that my Ballscrew and nuts DIDN’T ship last week after all.
I sure as hell got billed though……..
I was expecting to have them by now or very soon, I hadn’t gotten a tracking number so I asked for one.
Thats when I found out that my order had gotten “lost” in the “new” computer system, yea and my dog ate my homework.
looks like its going to be another week before I see them ASSuming they ship this week
I love your videos.
Thanks Ryke, I was looking at Cut3D and still might get a copy, its just so reasonably priced it’s hard to say no 😀
The TechShop just started offering classes in its use, might have to give it a try.
I’m using the keling 425 oz package with his 36v power supply
Yes YN they are NEMA 23’s
If I was dong it over I would probably go for either smaller steppers (280’s -ish) or move voltage.
The problem with steppers is they only achieve there highest torque when they’re not moving, soon as they start to move they loose OZ’s and the larger the motor the faster they loose them, so a smaller motor potentially could have more strength at speed or so I’ve been lead to believe
Ryke – Love to see some pictures of yours. I’m currently trying to convert mine with the Steele plans.
400oz/in steppers 😈 – Are they in NEMA 23 bodies?

I’ve got to get a better bandsaw setup, this hand held one just isn’t cutting it (no pun intended) spent most of yesterday cleaning up the cuts with the mill, just to get the parts close enough to start milling.
Did manage to get 2 brackets made though
the sharp eyed amongst you will notice that the counter sink holes are a different size on one, somehow when I made up the part in solidworks I didn’t notice that I had made the holes a bit bigger, I didn’t notice it until it started cutting
