Because you effectively only increased it on one axis. Z doesn't really need much. Perception of "slowness" is almost always acceleration...
The torque curve at 48V (cheaper & easier than 72V) looks more than good enough. You could probably get 25,000mm/s^2 accelerations out of that...
Just made a final decision on the Mesa hardware that'll be running this build, too: 6i25 PCIe FPGA Superport (HostMot/stepgen) 7i76 25-pin...
It's pretty normal for end mills not to hit exact spec; they're really just stating the size of the bar stock they're starting with, once it's...
Ok, just spent three days aligning the Y axis rails and trimming the table and adding some leveling feet I had lying around (may have originally...
Personally I'm building it in as an enclosure window so the beam is fully enclosed. If you have a fixed focal point that can't be adjusted with a...
Yep JTech Photonics sells laser shielding. Don't cheap out and buy orange acrylic, not the same thing.
Hmmm... I'd like to see a $# realtime request dump immediately before and after a job. Can you air-cut a short job (like, less than 2 minutes...
Oh, nice, well that's exciting. I generally just err on the side of "when in doubt, current limit".
Black to +, blue to -, 10k resistor between brown and black. That's how I'd do it anyway.
My diode has a screw-barrel focus on the lens itself. I use Z pretty much entirely to micro-adjust focus and dial in material thickness.
...Huh. Ah. That makes more sense. Guess we see what Peter's been alluding to the last few months?
Looks to me like a plunge or other consistent heavy force, like tool deflection in the -Y direction, has pushed the entire gantry carriage up and...
I'd consider adjusting the base frame and cutting into the table to give you room for 5 axes to carve globes like that- you really only want to...
I doubt, based on my experience with 1500mm extrusion, that a gantry router would do well with so little support. I've built a machine designed to...
Probably water cooled. Perhaps also the difference between 3 bearing and 4 bearing, body/rotor length, etc. Not all China spindles are created equal.
Feel free to send me some of those high helix three-fluters to, er, "test out" when I have M4 up and running. :thumbsup:
The only end mills I get what I'd call a "good" finish from are YG-1 Alu-Power 3 flute 45 degree high polish uncoated carbide. Cut like butter and...
Don't wait until the tool change- do the bore immediately after the face and then an M0 mandatory stop (not right on top of the part, learned that...
Sounded more like acceleration than top speed when I skimmed the other day, and these indeed look pretty low to me: I'd bump them up to 500,...
