True, but the belt is only about 40cm long where it goes over the pulley so the short distance means high strength and little stretching. The weakest...
2 belts = twice as strong. Belts are cheap so you can double your machine strength for like $2. You can upgrade belts all the way to the strongest...
I don't use a grbl shield. I don't use Mach3. You can measure the temperature of your motors and see if it exceeds the specs.
I agree and thanks for the info. I saw a technique for doing 2-sided PCBs which uses the same principle. With PCBs it's even more critical to get a...
The photos show what looks like a timing issue. I had the same kinds of cuts on acrylic. Try slowing down the timing when changing directions. On...
This doesn't work when the machine slips during a cut. You have to manually touch off the workpiece again to resume. A tool-mark helps make this...
Oh it's totally do-able. It's actually patented so you can do it at home but if you or openbuilds were to try to sell it, they would get sued. SO...
I don't think it would be possible to somehow ignore my wife:ROFL:
I think it's great that you can design boards. It's a big problem in CNC right now. Having a realistic, open-source design makes sense. If all the...
Some places sell handheld rpm meters too. You could attach a plastic disc with slots cut out of it and then pass the slots through an optical switch...
I tried the vegetable oil and it works similar to 80w oil but is much thinner and doesn't stink as much. I'll give the beeswax a go next time and let...
How many axes can an Arduino BOB handle?
You want something that can power a good NEMA23. I think the TB6600 boards can do 4A per motor?
The motors all have their own rating that will tell you the max load. For your application I would recommend threaded rod to lift the table...
The acrylic is on another chart. It says to use 200mm/min @50% plunge rate and 0.0762mm cut depth. That was for a 1/4"(6.35mm) bit. My spindle runs...
Who says we're guessing? The scientific method is what we're doing. We conduct experiments, publish our findings, and then reproduce the work of...
Yeah I just cut aluminum with my settings I used on acrylic. 20ipm is a little fast for me because I haven't completed the spindle yet but I would...
That's almost identical to my routy except my leadscrew is behind the v-slot rather than through it. The problem with mine is that it loses a lot of...
Sorry to butt in, but I think it may be possible to make a large-format OX using the 1500mm v-slot and then put the rollers on simply by sliding them...
This is the same for all v-slot builds, basically. So there's a little bending that happens in the aluminum Y gantry plates. There's a little flex in...
