X2 cnc finished for now maybe

[hoss2006]

Hey Will,
The serial cable wire was a concern when I put it together, it is really thin.
I was worried about the motors drawing too much current and fusing them all together someday. So far I haven't even got the motors or cables warm to the touch on some long engraving runs, even the Z axis was Ok when I forced a 1/2 in. drill bit thru tool steel. Must owe stepperworld.com thanks for a good design.
The serial cable was convenient and cheap, and made a neat and tidy installation. I'm looking to replace the 190 oz/in Z motor with a 300 oz/in here
shortly (to make drilling easier next time). I might have to start worrying again about the cable till it proves it can handle the load and puts me at ease. So far it hasn't been an issue at all. I wouldn't recommend the serial cables for really
big motors (500oz/in) but they'd be overkill for the X2 anyway.
thanks Hoss

Hey All,
My X2 lathe is coming along.
Have the DC motor hooked up, now I have to add the electronics
to get it moving.
Then I need to make the mount for the tool post
so I can try it out.
The stepper motor and the tailstock will follow.

that's pretty cool!!! so this is gonna mount right on the x2 table? where is the toolpost gonna go? all u would need to do now would be to put an encoder on the pindle and now u have a nice 4th axis!!

im planning on cncing my x2 and want to use your z-axis design. i have modeled most of the x and y in cad and will post it soon in a new thread

Hey skmetal7,
I'm in the middle of drawing up the print for the mount for the toolpost right now. It will bolt underneath the X2 spindle onto the the bracket I already have affixed for mounting my other attachments (engraver,surface grinder).
I'll use the X2 Z axis for the facing plane and the X axis for the turning plane.
When I add the stepper motor to this attachment,I'll have my 4th axis.
A single servo motor would have been better for both turning and 4th axis
but they're pricy and I already have these 2 motors. Free is better. So far
I've only spent $30.
more to come Hoss

The X2 lathe attachment prototype is ready to try out.
I got the electronics hooked up to run the motor, pirated more parts from
my Harbor Freight Mini-lathe. Plan to use an AC motor for it anyway so it
won't miss these parts.
I checked the RPM with my tach and it runs from 550 - 3100 RPM.
Started on the tailstock, it'll have an M-2 taper and about 2 in. travel.
Really just to support a long piece of stock with the live center.
Finished the toolpost mount that will attach to the X2's spindle.
Still have to order the 4th Axis components(stepper and controller) so it's
just turning for now.
Heading down to try it out and put Bob Adams Cad2lathe software
to use.

It Works!
The first test of my X2 lathe attachment went well.
I used Mach 3 Turn to try it out. Had to reconfigure the X and Z axis to match
what the program needed and remap the keyboard and my control panel so it jogged correctly.
Made a few simple test pieces shown here.
Need to make the new timing pulley for the motor since the stock one doesn't
match the XL pitch I need. Close but not quite. Will need to make a shroud for the motor and belt too. I'll post a couple little videos soon.
4th axis is next, will have to wait for payday.

Now that is cool!

Great work Hoss - keep them coming.

Have to play with some bigger stock tomorrow.

Hoss,

I think you are building the Swiss Army Machining Tool. Nice job.

A small suggestion is when you name your files that you use an underscore (_) instead of spaces. This will eliminate all of the 20 and % signs that are being displayed in the link.

F.Y.I. the links didn't work for me.

Looks like the servers down for maintenance or something, I can't get onto my site at all right now, try again later Hoss
