Hey Josh. Well, the Arduino running GRBL is a tried and true solution. I often use the Arduino Nano with a small screw terminal block...
Clecos are kind of like a temporary, reuseable pop rivet. You use them to hold 2 pieces of sheet metal together while fitting or drilling, in a...
I would say that the Workbee is far superior to the Shapeoko. More wheels, Workbee has 48 Extreme V-wheels, Shapeoko has 12 delrin wheels....
Not sure that's a graduation and not a return to grade school. I am of the opinion that 90% of the spindles on the market are Chinese junk (and I...
Buy them from the OB store, on this site. They sell the proper lead nuts and all. Don't use plain old threaded rod, it's junk for leadscrews.
You can cut leadscrew easily, you don't have to find a piece of exact length. Just cut it with a hacksaw, use a grinder to put a bevel on the cut...
Sure, you can use longer uprights to elevate the X/Z axis. Be careful with this, however, as making the supports longer and increasing the length...
No, it shouldn't "spring back". Each side of the Y axis is driven independently, the controller doesn't know if you do a manual adjustment on one...
No, it won't spring back unless your gantry wasn't assembled square to begin with, ie the ends of the c-beam weren't cut square. You should have...
It's exactly the same principle, regardless of the type of drive. His machine uses Rack and Pinion drive, and he is just adjusting the position...
Almost none. They are completely different. The only parts they have in common are a couple of pieces of 20x60x500, and some screws, nuts, and...
Glad to help. Spindles seem to cause a lot of trouble, especially the Chinese VFD types. I can't stress enough the importance of proper...
Sounds like a loose axis. Check to make sure you have no back and forth play on the X and Y axis, and no up and down on the Z. Grab the axis and...
Jim: Could be several things. Dull bit, feed speed not right, router speed not right. There are a lot of variables that only lots of practice...
Still Alive!
I've used an M5 low profile 6mm screw in a pinch... The low profile head will clear the inside of the c-beam. MG
Double nuts for sure. Way better. MG
Having the machine suspended by cables would be a very poor situation. It will flop around like a fish out of water when running because of the...
You might want to go back to the original Sketchup design on the original build thread, I couldn't get the one in this thread to open. There are...
Whats the hole in the middle for? MG
