Emco PC turn 55 upgrade..

There is meant to be a handshake where
iocontrol.0.tool-prepare goes TRUE, stuff happens, then the stuff sets iocontrol.0.tool-prepared TRUE

You can make it happen immediately:
net prep-loop iocontrol.0.tool-prepare goes => iocontrol.0.tool-prepared

The same is true for iocontrol.0.tool-change and ...tool-changed. That often goes through hal_manualtoolchange.

For a lathe you might want to change immediately on the T command, and not have to issue M6 and G43.

I'd like to be able to use the Tormach post without changing it to M6 G43 by hand, or learning how to edit my post.

Ah, yes, PathPilot already has that doesn't it?

You don't need to change anything, then.

I've been getting more following errors and eventually decreased my max velocity to only 900mm/min, but still got the error sometimes

What is the maximum theoretical speed of your step generator? This depends both on the base-thread rate (which sets a maximum rate at which steps can be generated) and what are the settings for stepgen max velocity and accel (and how do those compare to the TRAJ and AXIS values?

How many steps per second? That's one of the critical limits.
