How do you disable the HBP?

[FarrisGoldstein]

I have a FFCX clone (PowerSpec Pro). For some prints, I need the HBP to remain disabled. I've tried setting the temp point to zero, setting it to somewhere near room temperature, or even just removing the HBP from the Temperature tab altogether. No matter what I do, it either hangs indefinitely while trying to reach the "proper" temperature, or it actually heats up a bit, often causing some uneven warping.

What is the proper way to disable the HBP entirely?

This is probably because your starting script has a line in there that says something like:

M134 T0 ; stabilize bed temperature

This means that the firmware will wait until the temperature matches exactly what you set. This will cause issues if you try to make the bed reach 0 degrees Celsius (since that is impossible!). So you can just remove that line from you starting script and then set the bed temperature to zero and it should work.

That did it, thanks!
