RichGMD61, that's typically what I use, an Arduino Uno with the screw terminal shield, and TB6560 drivers I buy on Ebay. I plan on switching to...
stargeezer, why not just use an Arduino? Or, MACH3 and a standard Breakout Board? Or, my personal favorite, the Ethernet SmoothStepper? Any of...
Hmmm, interesting, stargeezer. I did think about a sandwich before, just not steel, but perhaps 1/4" aluminum. I think you would probably get...
hmmm. That's a lot of extra real estate. It should work, though. I have a couple of ideas I want to try. I'll keep you posted. I think...
Yeah. If you are standing in front of the machine, the x axis goes left to right, and the Y axis goes front to back. If I pull on the top of the...
I was also thinking that some of the flex you are talking about (clockwise/counterclockwise) might be due to the cheap wheel bearings. They are...
Hey EvanBruner: No, I meant the torsional flex was front to back, i.e in the y plane, not the x plane. If I pull forward on the top of the Z...
Hey guys: So, after completing this build (mostly), I gotta say I'm a bit disappointed in the stiffness of the unit. It's pretty good as far as...
Yeah, should work. Thanks Rick. I was just playing in the shop, and set this up on the X axis. Too much play in the in/out movement of the...
I just remembered a couple of old woodworking tricks. 1. If you run a work piece down a fence on a table saw, router, or whatever to form a...
Yeah, I just tried the router table thing and it's not very consistent. I didn't have a v-groove bit small enough to fit in the slot, so I used a...
No, they don't appear to. I can slip a piece of paper between each "cheek" of the wheel and the extrusion, so there is at least 4 or 5 thou...
So, just a bit more of an update on the Steel V-Wheel idea above. I ordered some 6mm drill rod from McMaster, and tried it out. Just placed it...
Man, Kyo , you don't do anything half-fast!:thumbsup:
That's the problem I am having. Although, I do not want to run anything much over 1000mm anyway. I've been holding off doing a 1000mm machine...
This is where I found the ones I mentioned: http://stores.ebay.ca/qtecstore/
Where do you get taps? I recall a thread on the list somewhere where one of the members was making his own lead nuts, using taps he made from the...
Kyo, do you have a source for the 10mm leadscrews and nuts? I found a similar type on Ebay in both 10 and 12mm, but lengths not longer than...
Kyo, you might take a cue from Mark Carew in the way he designed the XL Gantry Plates for the c-beam. Rather than messing around with trying to...
Cool. Thanks so much, Kyo.
