Brother TC-225 / TC-229 adventure!

well, the servo error issue on the brother control was directly related to my linuxcnc pc being wired into the machines 100v.

with the machine attached, error. without, no error. so the 100v line must be finicky. the drives for xyz are 100v single phase for some reason. spindle is 200v 3 phase.

under the Linux control, the z still errors. no matter how the power is run to the pc. y and z are fine, work simultaneously. z errors when its enabled. I'm not sure if its even the same error now, its just a red led and I have no descriptions.

I have to recheck again now on the brother control if theres any extra signals coming from the brother board to the drive. the only thing I can imagine at this point is an extra "brake off" signal.

were still likely a few days from getting to the atc finer points, but I'm thinking ahead

You probably want to be using G53 to move to absolute axis positions.

oh, right, to bypass any offsets. thanks.

Well. All I've learned is the z drive has 6 error let's and the x and y have 5.

The drive cable though does not seem to have anything special going on.

It has to be looking for a brake signal... but where?

Fixed. Was just timing. I set power up t e stop. Enable to Machine on.

Tuning is giving me grief. Up is fine. Down likes to oscilate. Any thoughts on a better start point?

You might need to set up the PID with a bias t to compensate for the weight of the head.

Jog the head up and stop, note the PID output. Jog down and stop, look at the PID output again. Then set the pid.2.bias to the average of the two values.
