To be fair, there are VFDs that'll convert 120VAC 1~ to 220VAC 3~ for spindles(check out LightObject), but the problem there is that you're...
1) Yes. Depends on your PC's output. (How to determine that, I'm not sure) 2) Yes. It's probably for PC control of power saving, so not really...
When you hit the edit button underneath your build writeup and go down and click on the body section to edit, just add the update underneath what...
I finished the thread last week, still have the same view, though marginally relaxed on the production tolerance front after the last few pages. I...
I'm looking at working with metal, so mass is exactly my goal, both for damping and stiffness. It's going to be a concrete monster, but I don't...
I'd be rethinking ACME rod or belt drive with that monstrosity on top, though it could be that only working grainless, knotless wood will make...
Rick's on the right path. I'm now almost finished the CNCZone EG thread, on page 382, and I can now pretty categorically state that 1) Concrete...
That was my assumption, the kW rating seemed pretty dubious to me. Thanks for clarifying!
The 2-axis gearbox is very easy, it's just a couple of (low-backlash?) worm gear drives perpendicular to each other in a cast aluminium case. I...
I came to the same conclusion. I originally liked the idea of hybrid machines, but as I've researched it more and more, I've come to realise that...
I'm not building an OX (I'm trying to work on something that requires no upfront machining), but... I'm planning on using 220V mains to my...
I may just be lacking comprehension skills or being lazy, but are there datasheets on V-Slot from the manufacturer? In particular, flatness (in...
I would personally guess that Delrin V-wheel in anodised V-slot would be your best bet- I tested my rail by moving the carriage quite violently...
Ah, ok. I was thinking it would be a little looser like the Maker Fair Primes over on the West Coast. Still, you got to show off your progress and...
From the research I've been doing recently, for the type of size and capability you want this machine to have, you're gonna need support beams...
The idea is fine, and 0.1mm is easily achievable, even using belt. We have a couple of hybrid machines being worked on on the forums, though not...
Both that and MachineKit in general look very interesting! Thanks for the link!
Oh, ok. Yeah, that I know- my last project was also custom software, but that was Arduino-based and the timing wasn't so critical. Typically pulse...
I've been doing a whole bunch of research on methods of linear locomotion thanks to @Tweakie's pointers, and figured I should put some of those...
Thanks, @Tweakie. Will do. :) That's good to hear, because long before a project like this will be ready, I'll be using LinuxCNC. Servos are...
