Cutter, it looks like you have the G codes down to an art. I picked up a Robotool cnc used a while back and so far I have just been using it in the jog mode because I haven't been able to spend much time with the Bobcad software yet to actually use the machine to it's capability. I have been able to draw a part and post it only to find out that I still need to build the tool library yet. There is still a few other things that I need to set up also, but am unaware of so far. This machine uses the old 3 1/2 inch floppy disk's to load programed jobs into it. Those are become harder to find nowadays also. The cotrol panel has keys to enter G codes and such, but I am not familiar enough with it yet to try.Maybe in the future some time I could use some advice about G codes though.

I still write most programs right out of my head/on the fly at work. Drives the "engineers" nuts sometimes that I can program and have a part in hand faster than they can program it with software, but something like that is a completely different story. Great job! You should consider engraving custom breech case medallions.

The controler on the Robotool is a CVM-1 and the post processer was downloaded from the Bobcad site into the Bobcad V24 software as far as I know that is all of the software.

You don't want a sketch from me, I can't draw worth a damn. I was just thinking out loud. Maybe an oval with "Gatling Battery Gun" or some such similar to a real one with the makers name and date of completion. A serial number wouldn't be a bad idea either. The oval could then be rolled to a 3" radius and polished out.

Maybe in a fancy font like this one from Anderson Gunworks.
Like I said, just thinking out loud. I'm not a big fan of the cast ones.

What program would you use for engraving on a cylinder or 4th axis? Great thread....

4 axis is software?

I have a 4th axis with mine, but I have not attempted to use it. The machine is ran by mach3....

Yes, do you need any special software for that?

The machines mechanics and electronics must be set up for 4 axis, also the software that runs the machine.
You'll still need software (cad/cam) capable of generating the "G" code for the 4th axis.
Most cad cam programs these days will give a 3 axis "G" code.
Then it gets pricy for 4 and 5 axis

Curious what your mill is and some details on your 4th axis. I have a vertex rotary table, stepper driven that I use for a 4th on my bridgeport. Also, what is the cad/cam used to generate the 4th axis simulation engraving a few posts back?

HI Sparky,
I have a Syil X4 plus with their 4" rotary.
Not much power to the rotary, but works well taking small cuts.

Is yours a 4th axis or an indexer ?

My cad cam software is Surfcam Velocity 5 axis,

My 4th will function as a indexer or rotary, it is a standard 6" vertex rotary table that I retrofitted to stepper drive. I have used it to cut the cams for my D&E gatling, the oscilattor cam, and putting the hex on the end of the barrells. I hope to get more experience using it in the future. I am using Mach for control of the bridgeport.

Sparky,
Here's a program to try, it's on a 2.00 diameter and 1.00 long, but you can hang it out there.
X 0. is on the right with Y & Z center of the rotary
The tool goes .006 deep.
Good Luck
