The only problem I see with the cantilevered y-axis is if the actual support brackets are insufficient. There's no reason why a cantilevered...
HF start messes with electronics because it generates RF noise (spark gaps were the original RF transceivers, after all). Full grounded shielding...
Sounds very similar to the machine I thought I was going to be building, before I got work that would require steel and aluminum capability. I had...
Pfft, that doesn't sound like as much fun! :D My only concern with captive ball bearings would be that they could drop into your kerf and start...
I'd say before jumping on the latest and greatest motors, you need to take a step back and think through your spec requirements. What woods are...
1) Add a small stepper and leadscrew for altering the spring compression (Hooke's law) and include this as an axis in your gcode processing? Since...
Oh! For some reason I thought you were cutting aluminum. Hmm, MDF is trickier. I'd probably go with some kind of double sided masking tape idea,...
99% of the noise from any kind of spindle is going to come from one of two places: 1) The airflow through the spindle, powered by the cooling...
The point of tabs would be to be able to remove the entire sheet and then manually remove the parts- as I said, perhaps a second op cleanup pass...
Seems like the obvious solution would be to either change the geometry of the vac table, or go to tabs and second op cleanup with a pallet system....
Hey, he said cost is no object! :D
The extra two axes would primarily be for indexing- eg. maintaining cylinders' concentricty to the print head for proper line orientation- though...
Rack and pinion isn't a terrible plan, as long as you don't need ultra-accuracy. Really long screws can start to get whippy without support, it's...
Is grbl writing it permanently high? I would assume, since stepper drivers typically only increment the motor on a rising edge, a step from grbl...
Just looked them up. Very handy! Gotta keep those in mind for the next CNC build after the one I'm about to start. Right now I only have a short...
I was in the exact same position about 5 years ago. Long story short: not gonna happen. There is a pretty exciting voyage of discovery along the...
Specifically a rotary tool/router collet, sure. They don't have much range of motion. Real 1/4" collets will happily take 6mm tools, I do it...
Collets shrink as you tighten them, that's what they're for. I'd try the 6mm in the 6.35 and the 3mm in the 3.2, just in case. If the relief slots...
Ah. That would be the problem, then. You really need to go through every one of those values and make sure it's correct for your machine. Grbl...
Exactly an order of magnitude off (0.25 vs 0.025) suggests it could be a simple distance-per-step mis-key? Say, "02" instead of "0.2" or something.
