Brother TC-225 / TC-229 adventure!

I used this, easily modifiable and exactly what i needed it for.
I had the same feedback but with mechanical switches.

Yes, we have a HAL component for exactly this purpose:
linuxcnc.org/docs/devel/html/man/man9/carousel.9.html

sweet! that seems to be exactly what we need here.

thanks.

well the machines have arrived. i need to have a 220v 3 phase plug wired, and i can plug the first one in and see whats going on. initial inspection suggests its in good shape.

chips! sady, not new ones. haha. yup, they are a bit filthy, but ive gone over them some more, pulling way covers off and they seem in good mechanical shape. dont feel any play, doesnt seem to be any backlash manually turning the screws on the x and y.

im pleased so far. ive determined that both machines should turn on, as is. so, that is the next step. still waiting on the plug wiring.

fun fun.

so, to the second machine for a moment. the tc229. ive found that the servo drive use 2.5mb/s rs422 serial communication. it suggests its a proprietary 6 byte data block. i assume it transfers both encoder and command, and other data in those 6 bytes.

any thoughts on if this could be deciphered and made to talk to linuxcnc? i can find some basic info on the chip, but not much detail yet. the interface chip is called sanyo ga1022, and is both on the motherboard and in the drive.
