Err: MinTemp Bed when Temp is 30 20 - 30 degress
This is new on a printer I have had working for almost a year.
The printer now goes through the prechecks. When it goes to start print that first line at the frontof the printer it goes into Wee: MinTemp Bed. Yet, the bed is at the assigned temperature but then starts to cool down. The bed is in fact heating to the desired temperature but stops when going to actually start the print.
I check the settings in Simplify3d and they are the same as I have used for sometime. I also try with other software to create the gcode and the same issue occurs.
Yes, connections to heatbed are soldered, yes I check the connections on all other parts and they seem fine. Indeed the bed heats properly. It just stops and gives this error even when the bed is heated to the proper temp to start the print.
Any ideas.

set the printer to pre heat for PLA
move the Y axis whilst watching the display, does the temperature for the bed change significantly?
if it does you probably have a bad wire on the bed thermistor, or a loose plug on the bed thermistor!

I preheat and move the axis around and nothing changes. The bed does heat fine. It goes through the prechecks fine when starting a print. It then stops at the front left corner. It seems to be that right when the gcode instructs the extruder to start putting out filament that the error occurs. Could this be something in the firmware or software?

I have more detail and this might not be because of mintemp. The calibration occurs and then the head moves to the front left corner and stops. Then the SD% climbs but nothing is printing. The heating seems to be shut off and temperatures go down until there is the mintemp error.
I think there is something else going on and will close out this item.

Where can I order a heatbed thermistor for the MK2s?
Re: Err: MinTemp Bed when Temp is 30 20 - 30 degress
Issue resolved - It was the bed thermistor. Works after replacing with one from Amazon Mmei 5pcs NTC 3950 100K Thermistor with 1 Meter Wiring and Female Pin Head for RepRap 3D Printer Extruder Heated Bed pre-wired or Hot End)
Then checked the old thermistor on the multimeter and another unit and it works fine. Odd as I vene retapped and positioned it before replacing. Oh, well. No harm. No foul and on to printing again.
