Anybody here work with CNC machines?
« on: April 27, 2020, 07:00:50 PM »
Of the skills & capabilities that I regret not having, welding used to be top-most. Now, 3-d printing is probably tops, followed by
large-scale CNC, then welding.  That said, large format CNC is likely more useful than (desktop) 3d printing.

How large is large format?  I'd like to be able to mill a sheet of plywood. 

I've bought the machine.  Anybody here know how to get started?

Good for you :)

no idea really, except my Father in law had one in his Garage. It cost an arm and a leg, and he never really used it.

I think he did our house name on the Gate, but that was about it.

What have you got?

(I have inherited a small electric welder, but am probably the worst welder you are likely to meet.  Perhaps I should put that on my "The Great Lockdown" achievement list... Improve my welding skills. )

For about 4 years now, I've been watching a guy develop 3d printers, then CNCs in kit form.  About 3 years ago, he started developing the 'Lowrider' based on his successful platform.  It is fairly mature -ver 2.

I think this is version 1

Altogether, the cost will be about $600 delivered.

Neat!  I have a godson who lives in Germany, and last time he was over he was talking about building one....

He now has the link, thanks! 

When does it arrives?

Same here.  I always wanted an electric arc welder.  I had a brief intro to welding in high school and I liked it.  Smithing with a forge was another thing I liked.

Today a 3D printer would be useful.

>arrive

The original concept was to 3-d print a good bit of the parts yourself and just buy the motors & controls. Now, it has progressed to "bundles" ....and I'm waiting for the hardware bundle to be restocked.  The other bundles have been shipped.

Here. But the site is something of a jumble.

I have a buzz box you can have.

An interesting CNC project - free plan for a food growing "sphere" released by IKEA:

I got one of those cheap chinese 3018 cnc pro ones, i thought it would be just as easy as laser cutting or 3d printing but it's far more complex! I think i need a carpentry course to fully get it :)

"Today a 3D printer would be useful."

They are a f###er for accuracy, especially holes obviously, if you print the model with the hole vertically then the bottom of the hole has a smaller diameter than the top due to it compressing on the bed. That's a worse problem the smaller your scale is of course.

"I think he did our house name on the Gate, but that was about it." that's so Dadlike.
