Yeah, a calculator is just the ticket. Nice find AR!
Yeah, the 1uF caps worked fine. Who says an old dog can't teach new tricks? Next machine will have NC limit switches. Enabling and disabling...
I believe they are NO. That's not a bad idea, if they were wired for NC, there is no way they could be triggered by noise, cuz they'd be shorted...
I recently put limit switches on my machine, and now I continuously get nuisance hard limit alarms. It's got an Arduino controller running GRBL...
As we said earlier, yes, there is certainly a method of calculating this stuff, but unless you are a mathematician or a seasoned mechanical...
How about a sketch so we can see what you are up to? If you are hanging a 34 lb weight out on the end of a 1.5' arm that is attached 90 degrees...
Yeah, the calculations for mass/inertia/speed/acceleration/tool force/friction/efficiency/etc are going to challenge a Mathematics professor to...
Professor Mode on Stepper motors operate on current. You must limit the current in the windings to prevent overheating the motor and burning out...
Anyone know of a source for 1/4" thick eccentric spacers with a 6mm or 6.35mm (1/4") bore?
dakman | OpenBuilds - Found a Canadian company that sells 8mm and 12mm stainless acme screws with anti-backlash nuts for around $60US. Lengths...
Ronald4418 | OpenBuilds I share your displeasure with the Canadian metric issue. We've officially been metric for what, almost 40 years? But 9...
Yeah, making a split collar is probably beyond my equipment capabilities. Besides, tapping Delrin to a 3mm thread for the clamp screw would...
Nice, Craig! I'm going to have to try this. I might just whip up a jig for the table saw as well. I looked at Dumpster CNC, he has some good...
Giarc | OpenBuilds How the heck do you make a tap for the acme screw Can you put up some pix?
This is what I did for the 500x750mm OX build to strengthen the base/side rails. I didn't like the arrangement with the 20x80 front and rear...
Yeah, I asked the store about it and they said it was because of the whipping issue. I found a seller on Ebay that has the exact same lead screw...
Anyone? Anyone? Just too **** lazy to make my own... :sleepy:
Ronald, you a Sketchup Machine, mang! Oh, and thanks for the tip about motor grounding. Never really thought about it before, but it's a good...
My plasma cutter hose is 14mm, the only other thing I would need in there would be the cable for the z axis motor. The plasma ground cable...
Hey Ronald: That chain is way to big. I need it to fit on top of a c-beam so no wider than 40mm, 30mm would be better. The E14-2-028-0 would...
