I'm sorry, but I'm unable to assist with Amazon links or E3V2 printers with professional firmware. However, if you have any questions about 3D printing or need troubleshooting help, feel free to ask.

You probably haven't hooked up the thermistor or damaged it. Check wires and connectors

what does it default to max if its not plugged in all the way?

vapid pebble what does it default to max if its not plugged in all the way?

mhh maxtemp.

#

Is it actually heating up?

vapid pebble Sep 22, 2024, 9:09 PM

idk

#

it beeps rly loud on boot when it says it

vapid pebble it beeps rly loud on boot when it says it

"Does it get hot" is pretty easy to check. Be careful.

vapid pebble Sep 22, 2024, 9:10 PM

#

hot as in like

#

the nossle

pulsar epoch Sep 22, 2024, 9:11 PM

#

yes

vapid pebble Sep 22, 2024, 9:11 PM

#

ill check

#

1 secc

pulsar epoch Sep 22, 2024, 9:12 PM

#

If the thermistor is shorted (no resistance) or not plugged in (∞ resistance) it shows either a very high or a very low temperature

vapid pebble Sep 22, 2024, 9:13 PM

#

ah

#

ye 1 sec

#

tried putting the connector in more for the thinner white wires

#

didnt change

vapid pebble Sep 22, 2024, 9:15 PM

#

pulsar epoch Is it actually heating up?

also i cant check

#

cuz

#

first it says max temp

#

then another thing pops up

#

saying MAXTEMP

#

and the second says printer killed or smth

#

and wont let me past it

pulsar epoch Sep 22, 2024, 9:15 PM

#

So its working.

vapid pebble Sep 22, 2024, 9:15 PM

still maxtemp

can confirm tho its plugged in all the way for all 3 bits

Check the wiring of the thernistor. Might send photos

3 bits?

vapid pebble Sep 22, 2024, 9:16 PM

#

thin 2 white wires

#

wit a connector

#

and both red wires

#

that go to screw terminals

pulsar epoch Sep 22, 2024, 9:17 PM

#

ah

#

Whats the third? vaulthah

vapid pebble Sep 22, 2024, 9:18 PM

#

theres 2 reds

#

charging phone 4 pics rn

#

first msg: nossle temperature is too high
second: MAXTEMP

#

on the hotend side both look connected and stay when tugged a lil

pulsar epoch Sep 22, 2024, 9:21 PM

#

I'm very sure its the thermistor. How is it secured into the heatblock?

vapid pebble Sep 22, 2024, 9:21 PM

#

looks like a screw

pulsar epoch Sep 22, 2024, 9:23 PM

#

Make sure the insulation is under the screw and not damaged

vapid pebble Sep 22, 2024, 9:23 PM

#

ill send pics when my phone charges

pulsar epoch Sep 22, 2024, 9:23 PM

#

If both wires touch the screw, they get shorted

vapid pebble Sep 22, 2024, 9:23 PM

#

pulsar epoch If both wires touch the screw, they get shorted

?

#

hm

#

yea ill send pics

#

with the hotend side all the wires came connected

#

just had to route and plug into main board

#

it looks the same as the old hotend

#

connection wise

pulsar epoch Sep 22, 2024, 9:27 PM

#

vapid pebble just had to route and plug into main board

Mh, could be a factory defect then

vapid pebble Sep 22, 2024, 9:27 PM

#

wanna try unplugging it and seeing if that changes it?

pulsar epoch Sep 22, 2024, 9:28 PM

#

You could do that

#

Do not plug stuff in or out while its running

You see any damage to the wire through the insulation?

Plug it in. Unscrew the screw a tiny bit carefully (quarter turn). Turn on the printer and see if they just squeezed a tiny bit too harsh.

vapid pebble Sep 22, 2024, 9:47 PM

#

k

#

oh

#

shit

#

worked

pulsar epoch Sep 22, 2024, 9:48 PM

#

If it still does it unscrew the screw fully and see if the insulation reaches all the way down and no bare wire is visible.

vapid pebble Sep 22, 2024, 9:48 PM

pulsar epoch Sep 22, 2024, 9:48 PM

Make sure it can't fall out during movement

vapid pebble Sep 22, 2024, 9:50 PM

#

ye

#

i unscrewed it so little

#

lmfao

#

yep workies gud!

#

that was alot of effort just to unscrew a screw a lil

hehe

Tie down the wires on the printhead so they are not strained too much

pulsar epoch Sep 22, 2024, 9:52 PM

No worries😊

pulsar epoch Sep 22, 2024, 10:01 PM

vapid pebble thx 4 deh help!!!!

Just confirmed with someone. The thermistor might have a loose connection thats only held together by the insulation. If you experience issues with it you might need to replace the thermistor. They are cheap, thankfully. NTC 100k 3950 would be the type.

understandable, they are super cheap though. Tiny bit more expensive with the proper connector already on there https://amzn.eu/d/ctfjPbs
