I just upgraded from V3 to V5, and there is a lot of improvement in how Meshcam generates a toolpath efficiently.
Robert just recently released V6. It will be interesting to see what it has to offer.

First off, I am just getting into digging around stirling engines,and I plan on building a LTD engine.

At the beginning of this thread, You planned on using aluminum for the displacer piston,,,...

Your A driver is shorted, probably from either an internal short of the A motor, or wiring problems. Xylotex can replace the driver for you. I had the same problem, and had traced the problem to...

Thanks, will do.

I've bought the program, and I use Mach 3, and downloaded the postprocessor, However, when I try to save multiple toolpaths, I get a message that mill program can't handle toolchanges!!! Granted I...

I ran into this problem myself,, with a Sieg X2 I converted,,,and it turned out to be the gibs binding in one direction.

No, each steppermotor must have its own drive,,,

I just tried your files, and J opened, J2 gave me an error message

True, but a tilt mechanism could be used for a bump sensor,,,, and would give you some mechanical adjustability of how much of a bump to bump, of course, It would be nice if the program could...

My experience is with .27 diameter coms,,,,, Have had good luck with carbide, and even better finish with diamond,,,,,, but they are small lathes. http://www.teamcobra.com/cobra/comlathes.htm

Watch what you plug in to the outlet, The old SA 200s put out 110 DC.

What do you have in mind for motors??

It is a unipolar driver,,, and you have to provide load resistors to limit the current to the motors. Having the relays on board is convenient, but personally, after starting out with a unipolar...

In Mach2, try changing the setting under the config tab, click on state, and look for "IJ Mode", change the setting, and rerun the code, and see what happens. I have mine set at incremental,,, not...

Sorry for being an ole stick in the mud,,, I even hate it when stores change their layouts,,, Just when you get everything figured out where its at, they change it,,,,, I'm thinkin you need another...

Hmmm, Depends on what you come up with for a machine,,,, If you were to go with a gantry router type machine,,,, you could try Meshcam,,,, its only 150 bucks,,, sometimes on sale for a 100.

In general, it wouldn't work,,, Mig machine power supplies are a constant voltage supply, with varying amperage depending on wire size, wire speed, and the distance between your work and the contact...

I assume your using the pump for cooling the tube? Seems like that would be one of the duties of the laser powersupply,,,, probably coupled with some sort of a timed delay for when the power supply...

Under "Motor Tuning" in the config tab, you would tell Mach2/3 how many steps per 1 mm,,,,, so I imagine it would be 100 steps per mm for X, and 50 steps for Y. Don't forget to hit the button marked...

You would need a rigid plade such as these http://www.demandproducts.com/hotknifehd_blades.html

We bought it from Demand Foam products out of Georgia, after we visited their showroom, The computer equipment was shipped from them, and the machine was drop shipped from europe,,, the manufacture...

The U wire idea,,,,, Kinda sorta how the Lathe feature works on their wire machines,,, However, the machine we bought,(and is not setup yet) doesn't come with the Lathe,,, just the turntable. When...

We just bought a foam cutter from Demand Foam products, and are waiting for them to show up and do the initial setup and show us the ropes on the machine. (a requirement for the 5 year warranty) The...

Assuming you're using Mach3

under "config" "ports and pins" checkout the spindle setup tab. It has a box labeled "special settings",,, with a laser mode frequency by feedrate percentage. Also you can inhibit the Z axis under...

Is it done yet??

What does Mastercam cost??

Again,,, Where can the gun and Polyurea HardCoat cartridges be purchased??? We are looking into cutting foam,, and that's alot cheaper than the production units.
