I’ve got a ridiculous idea…
Have you seen those printers with two print heads, but they are on the same X axis?
What if we mounted a second router, on a second 611 plate, with a second motor. Then you could install a chamfer bit, or something on the second router, and once you had it dialed in, you wouldn’t have to do any tool changes or anything.
You’d cut some parts, make some holes with the first bit. Then you’d move the gantry up, and move the first 611 plate all the way to the far side, then you’d bring the second 611 plate from it’s hiding spot, and start carving, or chamfering, or whatever.
You’d have to put in some special gcode to park/unpark the different carriages, and you’d have to attach the second 611 motor to the A axis. Then whenever you wanted the v bit, you’d have to replace Z with A everywhere. You’d also have to be careful the “idle” bit wasn’t chewing up something. Endstops and motor control would be very helpful in this case.
I’m trying to think of a really really good reason to do this, like you have to switch back and forth several times in a job. Mostly I would think if someone was making hundreds of the same thing, and it required two bits, then it would be worth it to buy the extra hardware, and fiddle with the gcode manually.
I’m not going to do it, but it’s neat to think about.
