Xray,

Well this is a very late posting on this subject, but here goes.   I recently got a New Hermes 3400 engraver, free!!   I ended up using parts of the original controller,  the motor driver board and the power supply. Everything else in the EP controller was deleted.

 I had to hand trace the motor driver board and develop a schematic, then rewired it to accept the parallel port inputs from Mach3. 
Very cheap conversion,   I am running upwards of 250 ipm.

very nice looking work!!!

Steppers look kinda small, you might have to go larger.

How to go from your solid model to a cut path depends a lot on what format the model is in. 

The 3d cam programs can be quite pricy.  You might want to take a look at freemill,  I believe it is by Vetric.

Scott,

Have you got some dates in mind.  I am going to try to get to this one, but need to plan far in advance.

Best way to check for missing steps is to reduce your accelleration and top speed settings in the Axis Configurations.  Then run your tests again and see if you are getting the same results.

Or subsitute the G0x0 & G0X24 for a G1 command at lower speeds than max.

Try this and let us know.   

Also,  do you always come up short of distance or do you go long.   If long, it is probably noise, short, probably missing steps.

Would anyone be interested in demonstrating my probe or camera, for compensation?  You can see them in the bargain basement.
If so please pm me.

Yes,  you can make a wizard that will create your gcode.  It will take some programming in basic to create the wizard.  The level of difficulty will depend on how complex the part you are doing.

Can you describe the part?

Like Bruce said it can be done.  Since each truck has a dozen+ balls in contact with the race at once, only one ball will feel the joint at a time.    I joined several in my router table build and it is pretty much bumpless,  I can hear a tic as I push it over the joint but I can't feel it.  At first I carefully milled the end of the first two that I joined and then bolted them down butted together but then the next two I just joined them without milling, I can't tell any difference since only one ball is at the joint at a time anyway.

I am still building and have not tested it on material yet,  just running the steppers back and forth, still working on electronics & wiring.

Saumur,

Mach3 lathe does have some conversational programming in the form of what they call wizards.  There are several different ones and if you can think up new conversational programming you would like, make a suggestion and maybe someone will make them.  Users with some basic programming skills can build their own. 

I have done a couple of wizards to generate ID grooves, end groove, parabola, and some other tapers.
