When you have to build your machine in a tent you know you have gone way beyond hobby CNC.

Thankyou Mark for sharing this awesome project with us all.

That there is no hobby build for sure. I like steel builds, but this one has a very serious purpose behind all of this expense and effort. There's some quality design and welding going on under that tent. Maybe this will eventually get moved to a more permanent industrial location.

I suspect that it will be stiff enough for most of us watchers. I wonder what it will weigh when completed. We need a poll for that, and a piece of scrap steel from the build as a prize for the correct guess.

Thanks for posting this build here.

yes... but DIY work

This will eventually get moved to a more permanent industrial location.

yes... it will be moved... or hold out

I wonder what it will weigh when completed

about ~3000kg

When I look at your pictures I can only say - holy crap! that's some awesome piece of gear your building there sir! - very nice!

Thanks for your answers Mark. I can only be envious of building something of that scale. 3000 kg = 6613 lb and 13.88 oz = a lot of metal.

that's a very interesting machine,
what will you make with it ?

[austin.mn]

HOLLY SHNIKIES! That is one heck of a large machine!

What are you planning to cut with that machine?

[LazyMan]

Keep the pics coming! This is just too cool.

[markcomp77]

Keep the pics coming!

I will try asap

its for surface treatment of mold (mould) for thermo forming machine (moulding machine)

[mredican]

Wow.

[fortyonethirty]

Awesome! What is the intended use?

Hi Bartuss
I have great admiration for your work! Nice stuff!
on that big 5 axis machine, did you have a brake or counterweight on the Z axis? or Does the self locking trap. screw do all the work? If so, the 50Nm stepper (that's about 7,000 oz-in) has to overcome the friction of the self lock as well? One more Q: What nema size are the frames are the 28 & 50Nm motors?

Just FYI if you're interested, I'm doing a 5 axis build here:

I like the idea of the counterweight that you did with the red & blue machine.

I'm working on a way to keep position on the Z when power is off.
What do you think about a spring for the Z axis counterweight? Or a power-off brake?

Nice work man! Cheers!

Excellent work gentlemen, I'm looking forward to updates.

[Jesse B]

That thing is truly amazing. Excellent work!

[RomanLini]

I knew it was big... But that picture of bartuss standing INSIDE the machine kinda bumped it from big to BIG...

This si the first thread I've seen of a guy standing inside the CNC machine he was building!

Great thread!

No comments on the CNC drill press?

It looks like the drill press did a fairly good job but it does look like it leaves some chatter marks.

Great job so far.
