Just took a nice scenic 3.5 hour round trip to Manhattan and back, got some stuff.
Oh, CubePro isn’t the most movable benchtop 3D printer as I remember. 
(I have tested CubePro Duo 1,5 years back and it was quite a nightmare. Any plan of conversion/total upgrade?)
That’s the only plan. Heated bed, new controllers, and hotends. The Pro should become my new ABS printer. The regular, I am not sure yet. Maybe I will do some multiple head tool changer stuff on it.
man those printers are piles of crap. But id love one to re-control like this.
The rigid structure of CubePro is potential platform for CNC.
I wouldn’t say so. I have real CNC’s with ballscrews and Nema 23’s on all axes. I still have to be careful cutting aluminum there. I do need an enclosed printer for ABS. So this will be for that.
man, where do you manage to find things like this? It would be so cool to work on a random printer and bring it to life, but I’m way to busy upgrading my simple metal 
I honestly have no idea. I’ve gotten some stuff from the awesome community members. The guy I got these from was my neighbor at Maker Faire.
@raykholo nice! Well gl on the upgrade👌
Those one are beasts to move, but they are pretty rigid and make a great retrofit base 
I’ve been talking to Brian about a ball-screw printer build to see how viable it is. Any thoughts? I’d probably do a multi- mount for Cnc… maybe diode laser. Make it air tight.

@Brook_Drumm the thoughts I have seen floating around on this are that screw driving machines in general cannot get to the required speeds for 3D printing.
With ballscrews, I disagree. I think you should get a 3040 CNC frame off eBay, just make sure it is the ballscrews kind and not the trapezoidal screw. Put Nema 23’s, a 24v psu, a control board (a 32 bit with high current drivers), and you’ll need to rig a plate onto it for your print surface and an extruder head instead of spindle.
You won’t have a lot of usable Z at first, but see how fast you can go.
That said, what problem are you trying to solve/ what limitation are you running into with belts?
The main benefit I can see from ball screws is ringing should be greatly reduced. Your much more likely to see backlash unless you get nuts with oversized balls or double nuts for preload though. More weight too. It’s totally doable though.
I have ballscrews just sitting around. Saw them yesterday. Just wanting to play around with them. I guess the idea would be a combo 3d printer / Cnc. Again, just for fun. I like to noodle on fun stuff in between serious work

Gt3 belts from Gates will also eliminate ringing
@raykholo
There many types of ballscrews with different lead [ lead is the linear dstance covered by the nut in 1 full rotation of the screw] common trapezoidal leadscrews have 8 mm lead which translates to 400 steps per mm in contrast 16 teeth pulley coupled with gt2 belt has 100 steps per mm .lesser the no of steps per mm faster it can move i’m not so familiar with ballscrews but i saw many leadscrews with 5mm lead which means it’s slower than the leadscrews? which ballscrews should i look for more then 8mm lead?
So… I actually think I can move my ballscrew CNC with 4mm lead ballscrews fast enough for what I was thinking.
8mm lead leadscrews just make a lot of noise when you try to spin them that fast.
I think an 8mm lead ballscrew, if such a thing exists, might be wonderful for such an application.
@Brook_Drumm check out the BOXYZ
@raykholo i have seen high-helix screws with as much as 50mm of travel per rotation. I was looking at these for an openpnp i guess the question is how fast do you want to move
A typical print speed for me is 60-85mm/s and travel at 100-150 mm/s.
