The SCR (or whatever) control in the new router is drawing pulses of
current, then letting the
SCRs in the SSR shut off during the gaps. You could put a "spindle on"
warning light on
the machine, like the big guys, although only the deaf would likely need
such a device.
A resistor, or small capacitor across the line would likely do well, too.
