swed: i am just following traces and reading documentation i am finding online. still tracing more circuits to see if i can find your issue, it might end up being that the controller chip is just stupid and needs replaced.

yaowenc: the MINTEMP is slightly different, a higher resistance is being found, have you checked the resistance across the thermistor? it should be round about 100k ohm at room temp give or take.  also, you might need to check that everything is plugged in fully just to be on the safe side.

thanks, everything is plugged.  open the extruder and check the cable of  thermistor. there is nothing special. I also dismantling the heater, and under this condition the issue close, the MINTEMP error is gone. and assembly back. Now it can work.
still do'nt know what happened, maybe something short under original  status.  Now I will study how to adjustment this printer.
Thanks for your reply.

i am curious about something. if you have a multi meter. i have circled the resistor in green in the picture. it should be labeled 472 and measure around 4.7k oms. i suspect you have a higher resistance across that resistor, either due to defect in the resistor, or the wrong one got into the pick and place machine in the factory.

if its possible can you take a look at it, and test it?

Thank you very much, I also have the same problem... the error message I go is
": Extruder switched off. MINTEMP triggered !
Error:Printer stopped due to errors. Fix the error and use M999 to restart. (Temperature is reset. Set it after restarting)"

measure the R13 impedance is also 4.7K Ohm and the label 472 means 47x10^2=4700=4.7K Ohm.
 I think it's right value. but the printer of mine still Extruder switched off.

I got the same result until I added the 'ini' file to the SD card.

I'm not sure what that is or where I would find it. Where did you get the 'ini' file?

I think this may be a mistake. the 101hero file is the G code command, this is the Text file.
using the software Cura can let the STL file change to G code.
and the ini file can get from the 101hero.com's download. that is the config file for Cura. that file is using for let Cura know the X/Y/Z Size and some detail setting for 101hero.

Due to there is no enough error message for us. It hard to finger out the real solution.

Try using the G code from the file 101HERO (MotoTest). it also get some reaction.
G28 can go home.
some G code command can get respond "OK"
but if the G code relate to "E", like
G1 E-3.0000 F3600
it will get the error message.
"Printer stopped due to errors. Fix the error and use M999 to restart. (Temperature is reset. Set it after restarting) "
This message is same I can read from the software "Cura"

I have try using SD card with 101HERO file. only go home can work.
Any 101HERO files from 101land. those are unzip and put on the root of the SD card, can not working.
the Extruder temperature do not have any change, I can using the finger for touch, what I have is the FAN's sound.

Does any one have the same problem like me? we may have the same issue need to fix.
