I've also had success using typical wood bits for some aluminum tasks, but I'd be prepared to throw the bit away when you're done unless your F&S...
Very cool! It looks like your old Z needed to be trammed a bit. That could also contribute to broken bits if you're cutting a slot that's deep...
Wow - I haven't heard good 'ol Bresenham mentioned in a few years. Good point about FP precision. I'm a little surprised that GRBL doesn't just...
Wouldn't that be awesome? My impression, after spending a non-trivial amount of time investigating GRBL, is that this is not the case. Best...
My understanding is that no steps are lost - it'll move 3 (micro)steps, not 3.2. The motor will do what it will do. Your resolution will be...
I've just remembered that I have a nearly-silent air brush compressor in a box somewhere. Guess I'll give that a shot. :)
I'm looking at adding an air blast / coolant mister to my CNC router for use when cutting aluminum. The biggest issue I've had when cutting AL is...
DraftSight works great for flat 2D cuts. If you want 2.5 / 3D, it gets complicated. Sketchup's modeling tools are amazing - it'd just be nice if...
Quick review: I've been using EstlCAM for a few months now, and it's amazing - this makes the other controller software I've used look terrible....
Some Background I started building my first CNC device around 2008. (More pictures on my blog CNC Router Progress | David Lively's Blog. All of...
:) I work from home, so I get to work on this during lunch, after I drop the kids off at school in the morning and before work, etc. I sneak time...
I installed the motor a little while ago. Everything is working great so far. (Of course, now that I've said that...) The way I have my Z...
Techvette published a new build: From plywood and linear rail to c-beam. I probably should have bought a kit. Read more about this build...
It's a Bosch Colt. I have a little 400W spindle around here somewhere I could try if replacing the motor doesn't solve the problem. I'd need to...
And that's the first time I've encountered the phrase "tramming the spindle." Thanks - the Tubes provided helpful explanations. :) And it looks...
Well, considering I can park this thing at the limit switch, walk away and come back a week later, and it hasn't moved, I'm don't think it's just...
Yes. It's rock solid. I've been over the mechanical bits a dozen times already; nothing new. :/ (That doesn't mean there's not a problem, just...
Ah. I don't have a gear reduction system. Motor -> shaft coupler -> lead screw -> AB block.
Thanks for the input, y'all. I ordered a new stepper today, with a bit more oomf. The Z is driven by an ACME lead screw, with one of those...
So, after going through about 10 different versions of this machine (1250 x 1000 c-beam router, custom plates yada yada), it's finally working...
