MAXTEMP triggered, system stopped! Heater_ID: bed !!
can anyone help?
You have a bad connection to the bed thermistor. A short circuit most likely.
Trace it back and sanity check everything.
all connection, fuse check nothing abnormal.
And what does the temperature of the bed read?
If it is shorted then it is shorted.
That is a bad connection or a damaged thermistor (or in rare cases perhaps a damaged control board).
Given what you worked on I would go with a bad connection.
when i on the printer it show mi the error msg. i can even go into the menu.
You should be able to go to OctoPrint (with a web browser) and see what it thinks the temperatures are.
both bed n ext show off. i cant on it.
Does the error occur if you power it up with the bed removed?
@WheresWaldo has an R2 he might have some other ideas for troubleshooting.
yep.. i even try remove the cable from the main board.
You might want to go ahead and schedule a call with tier-2 support (since it takes as much as a week to schedule) and if you manage to get it sorted before then you can cancel it. Either the pogo pins are still malfunctioning or something else has died so you will need to get with them for warranty parts either way.
noted.. thank very much
You only replaced the pogo-pin board? Max temp would indicate a direct short, as these are NTC thermistors (negative temperature coefficient) and as the temperature increases the resistance decreases. 0 Ohms or a direct short would show as maximum temperature. A picture of your pogo-pin board would be helpful.
new pogo adaptar
It looks okay, is the error you get when you turn it on 'BED Not Connected'?
once i on my printer it show this msg straight.
If there is no short all I can tell you is what Mark told you arrange for a tier 2 support call. Because a short is the only way to generate this error, if you pull the bed you will get a bed not connected message instead.
i think ther is a short after i install the new pin. after tat the printer restart itself thn the msg appears.
If that message appears with the bed removed it is absolutely a short in the pins or cabling.
switch back the old pin still have the same msg..
