As I try and track down Thomson rails I'm sitting here trying to figure out my total bill of materials.
Please tell me if I left anything vital out of my list, my head is fuzzy
1. Computer
2. Cad software and G code processor software (some are freely available)
3. xylotex XS-3525/8S-3 Stepper motor driver board
4. three 116oz steppers from xylotex (or better somewhere else?)
5. Parallel extension cable
6. Power supply... 24VDC (any common transformer plug??? or not?)
7. ?????
Thanks for your input. I might need more info on the power supply if I can't just use a plug with transformer. I've built power supplies before for my audio amplifiers but have never designed my own. Any plans?
Thanks!

If you're going to use the Xylotex, you should be able to pick up a 24V switching supply on Ebay for about $10 to $20.

Thanks for the schematic.
Hi,
can anyone point to a website that sells Toroid Transformers with say a 24v secondary and 10-20 amps capability?
Thanks
Try these people for toroids.

Hey what size machine are you planning to build, I'm looking at building one myself but my instructors think that the 116ozin motors are going to be too weak. looked at getting some 200's but it's kinda spendy for my budget.
What instructors? At School? Have they built a machine? Just curious.

I wish it wouldn't crash.
I'm building an all aluminum 24 X 36 cutting area CNC Router. It will be using a 1.75 HP Porter Cable router, possibly my 3.25 HP Porter Cable router for larger jobs.Originally posted by DDM

From what I've learned from the people here is the 116oz motors will work just fine with 10tpi acme rod. I estimate my gantry will weigh between 50lbs and 75lbs with the router.
Even more torque is great...but always costs money...

Well I'm starting to think that my instructors or at least one in particular is there because he can't get a better job in the industry. I was working on some G-code stuff today and I've got a pretty good background in manual machining and he was having me do some really stupid things with the code. Making it take longer than it would actually need, and all we are cutting is aluminum. Oh well, I get the little piece of paper that says I know the basics and get the real education I guess. Sorry to get off topic. I'm going to try and go though the math on the restriction due to friction tonight. Does anyone have an idea on the static coefficient of friction is between the acme screw and nut and then a hardened runner and bronze bushings. I'll do some checking in my physics books. Just hope I don't run into any Calculus.
