I have just fitted a BLTouch to a Sovol SV01, and flashed Marlin 18.104.22.168 firmware. Bed leveling etc and building the bed mesh all went OK. Slicer is Cura 4.7.1.
However, it won't print.
The Gcode created by Cura after macro expansion etc is as follow

It heats up the bed OK, and it starts heating the nozzle. It then does the three point level OK, then waits for the nozzle to get up to temperature (200) - the M109 S200.
But that is as far as it gets. The nozzle comes up to 200 and generally moves between about 197 and 203 degrees. The bed sits at around 60/61. I can hear a fan keep speeding up and slowing down, and the info display just says 'E heating ...'. That's it.
It cannot seem to get past waiting for the nozzle to heat - but it has, and M109 S200 should wait for it to reach temp, and continue.
Can anyone advise what has gone wrong here?
