Cutting aluminum with small carbide tooling usually taxes top speeds because there's not really such a thing as an effective top surface speed for...
Look at the torque curves. Which has better performance at the microstepping rate and RPM range you're planning on using? Steppers are rated at...
Could the post just rephrase it so that it still conveys the same information to the user but without the extremely long sentence? So (When using...
I wouldn't use any rotary tools if at all possible- too much chatter and easy catastrophic error with both routers and Dremels. Some kind of...
About the only realistic option I can think of to modify the extrusion is to cut some wooden blocks to as perfect 90 degree angles as you can...
At those sizes I'd consider building a frame/table/enclosure for something. Not sure I'd bother attempting to force them into being an actual...
I'd stick with their idea of ball bearing slides- enough jolts from the road and plastic V-wheels would develop flats, even disregarding the...
Yep, that. I've flashed it directly from Windows command line in the past with AVRDUDE. Easier with the Arduino IDE, but that's also just a stub...
G-Penny spindle arrived! Interesting technique on the "balancing" of the ER 20 nut, but I suppose that's what they're working with at the price...
Wheels can absolutely be too tight, as can the anti-backlash nuts. They need to be tight enough to eliminate excess motion, but not so tight they...
The screws are probably ok, as long as you can't rattle them back and forth in their mounts. Did you tighten the anti-backlash nuts enough? The...
I use Mesa 6i25 FPGA PCIe I/O cards as the parallel ports. It's not a cheap option at around $100, and Mesa components tend to be somewhat fragile...
You would definitely need true simultaneous 4 to do knights and possibly things like kings and bishops. For that, you just have to move on from...
How big/heavy are the boxes? Does the robot frame go inside of two 800mm deep shelving units? A diagram would help. What are you actually trying...
grbl accepts M0 mandatory stops, which pause the program until cycle start or resume is pushed again.
Nice! With so much machining space available, you should do a double-carriage Y version of the high-Z with A-frame extrusion, so that the extra...
Yeah, it's certainly been a year! Well that's awesome! Lots of people are getting new shops at the minute, maybe the real estate market is right...
Sounds like a somewhat similar setup to mine- if a little further along. I don't have space to put/run the wood tooling I have now. Feel free to...
I was literally wondering where you'd vanished to just last week!
