Mitsubishi SSCNET

I'm wondering what the original controller did to drive the two carriages independently since I suppose everything came out of the same Gcode. A lot of it was probably handled in the CAM but it certainly seems that you would need two independent linuxcnc installations with the gcode for some of the axes passed over from one to the other with some sort of synchronization.
Thanks for posting. I'm looking forward to see what you come up with.

afaik, mitsubishi controllers have a "system" entity. i belive it's an independent g-code interpreter+interpolator. for this machine has
system $0: Z1,X1,V
system $1: Z2 X2
system $2 ??? aux functions - workpiece removal
spindles are shared
i don;t have yet a programming manual for the traub, i'll try to obtain one. i guess they have 2 g-code programs running simultaneously plus some means of synchronization between them

there's also a fanuc robot on the photo in the background - i may try to get on it too

Awsome! Lot's to look forward to.

LinuxCNC can use absolute encoders, you know....

yes, i know. but i still use them my own way: a patch to add "joint.x.set-homed" pins and saving motor-offset to the .pos file...
