Yep, motorcycle fork covers,  I guess the red was a dead giveaway.

Got the leadscrew on ebay for $79,  it is very nice, brand new, 4 circuit ballscrew.  It's original cost is probably many many times more that my whole lathe.

Show"N"Tell ( Your Machines) / 13x40 lathe conversion
« on: May 14, 2009, 03:47:42 PM »
Just thought I would share my lathe conversion in progress. 
It is a harbor freight 13 x 40. 
I am going to use a servo on the Z axis and a 1200oz stepper on the X.

Metltek,

Yes please can you give me the settings, or maybe post a text file?

Thanks

Curtis,

Yes, it will affect the speed.   You will want to slow it down.  After the change it will try to go the 3" in the same time that is was moving the 1/4", or 32000/2000 = 16 times as fast.

Pretty impressive PLC especially for the price.  It looks like it should work with Mach, lot of ways to configure it.

You might be in incremental jog mode.  The jog mode toggles between 3 settings, incremental, continious, and off.  incremental just moves a set amount for each press of the axis jog pushbutton.

What is "quick start preload"  ?   I am not familiar with that.

What are your motor speeds, steps/in, & accelleration settings?

General Mach Discussion / Re: Point cloud to G-code. What do I need?

I think you need to mesh it first, using either option under mesh menu item.   Delauny or ball set, either one.  This creates a mesh grid that can then be saved as a stl.

Tubular,

Looks like you may have 2 problems,  maybe they are related.    Are you using a wizard for the Gcode?

The X moving looks like a taper or chamfer command in the threading Gcode command,  don't know how else the x would move during the cut passes.

The z pitch change is very puzzling.  I think I would maybe write a short gcode series to move the z 6 " at a slow feed rate towards the chuck then rapid back to the start and repeat 20 times.  Put a dial indicator on the chuck end
and watch to see if it comes to the right place each time.

Good luck!!

Arnie
