Going to drive it with GRBL for now, so other cnc software will work on it just fine. I am working on driving the steppers, having some issues with getting them to move right, but upping my voltage and retesting soon.
He is wanting to engrave a bunch of plates etc. So I am going to 3d print him some beds that hold the exact sizes he wants to engrave, adding a camera to it as well so the machine can self calibrate. It can scan the bed for plates, and then automatically know sizes, shapes, and how many are there. Then the software will just ask him to add text,etc. to them, and click go.
I ripped off all the air stuff, and going to keep the air to the blower for debris removal. The Z axis I am replacing with a screw just like the other axis, but will only have a short travel distance. Also adding limit switches for homing.
All in all, should be a really solid machine when im done.
It appears to have been built in 1988 or so. Trying to get it as close to point and click as possible. The guy who bought it knows nothing about machining, and want it as hands off as possible.
Let me know your thoughts. I have tons of background in solutions like this, so it's right up my ally. The software, especially the camera, is going to be a blast. If it all works well, I might offer it to others on here, or sell it ask a kit, if anyone is interested.
