MINTEMP error

Post by GE_Rik » Thu Dec 10, 2020 7:00 am

Hi
I keep getting a MINTEMP error when trying to preheat the bed and the printhead on my Thinker SE.
My printer is in my workshop and now we are in winter here in the UK the temperature in there is sometimes only 1-2C before I turn on the heater.

Could this be the problem? Or is it more likely to be a loose connection?

Sometimes the error suggests the printhead is the problem and sometimes it says it's the bed which is causing the problem.

Thanks

Rik

Hi,
The printer of thinker se firmware limited the temperature: 5C.
The 5C is the minimum temperature of the printer.

At this temperature, the printer heating will be affecting by this.
It will hard to heating more than 80C. But heating for the PLA is ok.

If you want to use it at this low temperature, you can download the firmware and open the "configuration.h"
line:440 and 441

Code: Select all

#define HEATER_0_MINTEMP   5
#define HEATER_1_MINTEMP   5
You can change it to

Code: Select all

#define HEATER_0_MINTEMP   -5
#define HEATER_1_MINTEMP   -5
Last, if you don't know how to, you can give a reply then I can help with it. :mrgreen:

That's great. Thanks
I was beginning to wonder why the printer sometimes worked straight away and at other times gave the error. I hadn't made the connection with the weather.

I wonder why the default min temp is set at 5C?

Hi,
Here is the firmware for you. But I need to point out: Why we need to set the min temp to 5C.
If the temp sensor doesn't work or damaged, then it will show 0C. So when you heating, the printer will tell you the info to stop it.
This feature will protect your printer. But don't worry about it, another feature of the firmware:
If the temp of it won't raise at a limited time, the printer will be halted.

Firmware:
