Hello All,
I’m trying to customize my end gcode to make the chamber/exhaust fan & the auxiliary fan run at 100% until the heatbed is below 40oC and then everything shuts off.
Here is my current end gcode from LECKIESTEIN using his Steinwipe feature. I’ve highlighted the lines I’ve added/edited on the R and the original gcode on the left. What’s currently happening is the correct fans set to 100% but then I immediately get error “HMS_0300-0100-0003-0008: The temperature of the heated bed exceeds the limit and automatically adjusts to the limit temperature.”
The fans then stay on indefinitely at the end of the print and it never reaches 100%.

Try changing M190 R40 to M190 S40
R40 means “exactly 40”
S40 means “at or below 40”
Nice to see another Leckiestein user on here!
Thanks. I’ll try it now and see what happens.

It worked great!!! I ended up changing it to 45oC because 40 seems to take forever.
I also caught my mistake in the code that kept the chamber fan running. I have it set to keep P3 at 100% even though I want it to turn off at the end.
