I can get you a chip number if you need it still.   I had to do the differential driver for my Kollomorgen driver also.  It is fairly simple,  step & direction in to differential step/dir out.

I never ceases to amaze me on the wealth of information and ideas that are out there on this forum. 

You guys are great!

Thanks for all the feedback and good ideas. 

There are some truly good ones here I will have to look into.

The depth of cut is 1.8" , that was about as deep as I could get with my rotozip bit.


I haven't thought about what to do with it,  I would like to find a market for this kind of stuff.   

Put a nice simple frame around it.

I thought of doing one like it of the local lake and show it at the marina to see if they would be interested in selling smaller models.

There might be some interest in this from groups like the Resource District,  Visitor Centers,  Fish & Game  ???   

If anyone has any ideas on a market for this,  I would love to make a buck or two to help support my bad habit of building & playing with cnc machines.

I did this with Mach3,  the file was generated by Vcarve from a grayscale bitmap.
it is 18 x 24"  took 3.5 hours to cut from pink foam.

2 light coats of plaster and then airbrush painted.


I have been making a few Yard Elfs for my wife.    They are pretty simple mdf cutouts with accent lines that she is painting for Christmas decorations at her work place (the bank). 
She is really enjoying the fruits of my efforts,  she is just mesmerized watching the machine just cutting away.   
Now she wants to learn how to run everything, starting from the clip art to the finished pieces.


General Mach Discussion / Re: centering cross hairs on video camera

If you need a idea on how to make it adjustable check out the bargain basement under my machining camera. 

Then to calibrate it.

What you do is make a target mark, (i like to scribe a X on some scrap)  position your camera by moving the table so the crosshairs are over the target mark.

Then turn the spindle 180.  You will probably find the scribe mark moves off from the crosshairs.

Now adjust your camera mount adjusting screws so the crosshairs move 1/2 way back to the mark.

Then move your table again until you line up the mark under the crosshairs.  repeat these steps until the mark doesn't move from the crosshairs, it just rotates directly under it.


If nobody has, I will give it a try tonight.

I think it is in the regular download of Mach3,  you just have to go to the config. menu and config plugins and enable the VIDEO one by Brian.

some more pic's

note the cable system to prevent racking

Finished up to the point I can do some cutting. 

I have a few unusual characteristics, note the y Axis drive system close-up. 
I haven't had time to do any linearity tests but it seems to run real nice.  I can do 400ipm on the
y with no loss steps.

The x has a lot of power but the ballscrew has a little bend in it and it starts wobbling real
bad at anything over 200ipm.  I think I will probably put a larger screw on it.
