Brother TC-225 / TC-229 adventure!

Not so far, though the devil is in the details

ok, computer and mesa card set up, and important brother signals for start up.

now, how do I get a start up sequence going?

basically, I need to engage the main start up relay, and then, after a second or 2, engage the Z axis brake release. where would I add this in so it happens when I "turn on" linuxcnc?


thanks.

hmm, I see the first half of that is easy enough, haha. (I'm at home now, so no machine in front of me, just reading the docs). just tie that button (axis.0.amp-enable-out) to an output to that relay.

so its more now attaching the brake release to that, timed a few seconds afterward.

This was discussed on another thread in the last couple of days.

Use the machine-on signal to turm on your main relay.

Then send machine-on to a timedelay component to enable your brake. Easy!

timedelay has an on delay and an off delay pin so you can decide when to trigger it when you turn it off. Probably with a time off delay of 0.

cool thanks!

ill read through that.

Do you want it to be a few seconds later every time? Is there an Amp-ready signal from the Z-axis drive that could be used instead? That seems like it might be a better way.

a time-delay on a HAL signal is very easy, though.
