Set of circumstances with Tap that causes print failure #9

If you follow the instructions for voron Tap's config alterations, have the printer cold, with bed temp below 90c and then use this macro, you'll get a "hotend too cold" error. I moved hotend heating to after bed heating but before the 5 minute wait, that fixes the problem. Adding a sufficient delay before it tries to QGL would probably also fix the issue. I have a Dragon UHF which may also have contributed to finding this corner case, since it's more material to heat.

Hey!

So the macro has a command called “M109 S150” which translate into “Set extruder temperature and wait: M109 [T] S” where M109 always waits for temperature to settle at requested value.

I’d double check your PID-tune to make sure that the hotend is keeping up with the set temperature of 150c.
