Time to put a wheely bar on it though so you don't tip back!

How much do you think it weighs at this point?

I don't expect that a single screw system would be suitable here. Not with that kind of momentum.

The "3d print" thing at the top is actually a link to another forum, just for 3d printing.

Any pictures of your Z axis mount with the ball screw? I'm trying to figure out how to do mine.

Checkout existing lasers and see what they say they can cut. Then compare to the power requirement they show.
There are some changes needed. Mostly in that you don't want to be moving the expensive...

Cinematic, I think it's rather obvious that what he meant isn't converting a router INTO a laser, but instead a CNC router system to USE a laser...

And yes you can.
What are you looking to cut...

Could always open it up anyway then add a layer of epoxy to stiffen it?

Thoughts on the table.
Flip your assembly over. The plate between the X and Y axis should be as short as possible, and large enough to mount the linear slide blocks upside down, and the ballscrew...

He's right. That's really kinda a no go.

Some stalling and something loose? Check your shaft couplers and bring down the velocity/accel for now.

If I remember correctly there is a good reason for the Z over the H pattern.
In the H pattern when the platform crosses longitudinally (on an H, being from left to right), friction will push more...

Did you end up just using nuts in those miny extrusions? Or did you find a drop in "carrier nut" of sorts? I've found upon disassembly (rebuild) that many of the nuts I was using dug into the...

Then wouldn't we get the same crap just made here?
No, you get what you pay for; it doesn't matter where you get it from at that price.

So with this model now in mind, if you were to be given a mill would you want the Tormach or the Torus Pro?

Those are BEAUTIFUL ballnut mounts.
Someone *hint hint* should start making and selling something similar for all the different sizes *nudge nudge*.

"Widgit Master Productions" *NUDGE NUDGE*

Test your backlash with a gauge and parallel.

Is it off in both X and Y?
Are you running with any backlash correction?

Actually while many think it's needed to have the radiator before or after the heat source, in any closed loop the flow rate will almost always make this unnecessary. The coolant will not warm up so...

You really are keeping that welder busy...

The search function is probably a very good place to start, this is not an uncommon project.

I have a bunch of motors like that... And now I'm going to attach project boxes to them all!
Never thought of that! :)

Very clean as usual there WM.

Sounds good. Seems to me that just attaching a ballscrew to the side of the column is an easy way to do this. Then pulley and motor up across the top.

Thanks everybody.

Thank you very much, both of you.
I know stock screws isn't exactly ideal, but until I can break this unit down to properly measure screws and how I'll mill into the saddle they may just have to...

Okay, 10mm shaft.
I'm either going to have to mill a keyshaft and try and file it out, or try a clamp on approach...
Good to know though I don't have to order more pulleys.
Is the X shaft the...

I'm about to just do a quick and terrible looking CNC conversion to this extra x2, and I'm feeling pulleys over direct drive as I've got quite a few 20 tooth timing belts and pulley sets sitting...

Damn. I have a g540 sitting about since a while ago....
Might have to resell that with it's 380oz motors.

Hey Hoss, would you still take the G0704 in this price class?
And for electronics, how are these new 3-in-1 setups from Keling? The competitors to the G540 but 60v/6a? Do you still prefer separate...

G0704 is a better machine.
Are you talking about the round column? That's a no go.
