RE: Core One: Who is designing a controlled chamber heater for the left side pocket ?
Can you tell where the Creality unit measures the set temperature? The product pictures don't show a separate cable, I wonder if it's measuring the air at the intake.

@Cedric I think, its not optimal to mount the heater in the same height as the printhead. So the hot airflow goes directly to the printhead with probably temperature problems with loveboard etc.
Prusa constructed the heating airflow in the C1L from below the printbed. There are no heat sensible parts. This configuration I'll test,when the heater arrives.

I have been working on this and it can reach 60C probably higher I just don’t know how the other electronics will respond. That is what that side pocket mod was for

its early stages though

That would only be an issue if the print head would be parked directly in front of the air stream, in combination with a very high chamber set temp. In reality it isnt as far as I can measure, i have probed around a bit with a thermocouple at different bed heights both before and after the mods, so I have quite a good feeling of what the heat spread is around this printer. The heater only blows really hot when the chamber is cold, as it closes in on the 55-58 degrees it adjusts the power way down to almost nothing too keep it there, since the printer can pretty much reach that on its own after a while. The main goal is to speed up the heating process to shorten the start to print, reaching 55 degrees when starting from 7degC takes a loooong time otherwise. I thought about putting it in the side panel, but this was by far the least effort to get a heater in, and very quick and efficient since I dont have to heat up 20kg of steel construction below the bed height, which normally on a Core one runs really cold due to the slim design around the bed.
The creality heater measures the temperature on the inlet, which in my case is at the back end of the housing, not that far off the printers own measurement. But be aware that the measured chamber heat is only what you measure at the sensor position, the temperatures around inside the chamber can differ quite alot compared to that number, in both directions during the print time.
