• Sewer pump
• Plasma cutter wiring

Sewer pump

The new sewer pump arrived yesterday and I fitted it today, seems to be working so far, need to keep an eye out to see if it is tripping the alarm.

Plasma cutter wiring

I have wired both of the motors in now and had both axes moving simultaneously controlled by the plasma-wifi interface.

A few problems with the plasma-wifi interface:

• when it starts up it says "Coordinate restoration could not be verified; reconnect to retry" and "Restoring work coordinates..." but nothing happens and I need to click "stop" before I can jog even though it is in "IDLE" state
• the jog controller sucks, should copy the one from https://github.com/jes/pugsender

I accidentally crashed Y into the end of the axis and it ripped the belt out of the belt gripper:

Which in a way is fine, nothing actually damaged, but I would rather it stalled the motor and tripped the alarm instead of creating a problem that I have to repair.

Still need to do the power LED and alarm LED, then move on to triggering the torch from FluidNC.

I'm not 100% sure how to do the alarm LED. The HBS507 servo drives have "ALM+" and "ALM-" pins - do these just get shorted together when the alarm is tripped?

Apparently the opposite - they are shorted by default and become disconnected when the alarm is tripped.
