Ok,
so the principle is: What goes in must come out.
It goes in via the mains cable, but at the moment it comes out into thin air
around the signal cable (or whatever it is) that picks up / radiates the
noise.

Disconnected the UPS from the 240V mains and system is not affected by
lights starting. Also, when reconnected the only thing that make the motors
jump are the lights even the compressor is ok - ignore my comment above.

Odd question..
Do you have slotted photo-interrupters that might be picking up the light
flicker?
It's unlikely, but no harm in ruling it out.

Machine jumps even with lights that start first time though.

I would be looking at the position loop in the drive for that problem. As far
Hi Jan,
Workshop is on a 20A spur, light come off the spur on a 5A spur. CNC system
(controller and PC) are connected to a UPS with surge protection. I'll give

Enhanced Machine Controller 2.4.7 has been released. Debian packages
are availble from the regular package servers. A source tarball is
available at

Due to a mistake during packaging, this version will still identify

Andy,
It is a very difficult situation to judge from 6000km away.
But my first sort of gutfeel would be to think that the noise enters the
system trough the power connection.
Have you got the drives' supply from the lighting circuit? (220V?) is it
possible to move it with a long extention to a comp
