SOLVED - Heater Temp not increasing after initial test.

[Phaedrux]

@anvil said in PLEASE HELP- Heater Temp not increasing after initial test.:

a Semitec 104NT4 thermistor

Do they give any values for that thermistor?

Doing some googling it looks like the same as the E3D thermistor and it uses these settings

M308 S1 P"e0temp" Y"thermistor" T100000 B4725 C7.06e-8

@phaedrux

change in thermistor values made no difference.

I dont understand how changing the hotend thermistor values would change anything if when i swap T0 and T1 in the m307 definition in the config the nozzle then works and increases in temperature until it dead times out from the bed thermistor not reading an increase in temperature.

Does it not seem like a config issue of some sort? I figured that changing those tool numbers sort of indicated that its a config issue... like the reprap configurator has gotten something wrong or I input something wrong in it and then its burried in the .json file somewhere and i just dont know...

Ive reached out to phaetus to ask if there is anything im missing or if there is any values they may know of.

Is the forum the only place to get support for an issue like this? I really need to get this sorted out asap.

How do you have it wired? Your config doesn't define a t1 at all so not sure how changing that makes a difference.

Can you show how it's wired?

Its sort of a process to remove and open the enclosure....but i have the heater wires coming out of the e0 output connector.... but i think im finding my issue...in the reprap configurator
SO... currently its labeled like this for the I/O mapping/ heaters and tools

but it looks like in the I/O mapping section i should swap nozzle and heater so the nozzle output is on 0 and the bed is on 1

but when i do that and go to the tool define section It wont let me select the H1 option it just keeps it N/A

should i just swap the wires to the e1 heater output maybe and see if that works?

Im not understanding why it wont let me select the nozzle as the 0 heater in the mapping page and also define it as a tool. and i tried changing it to tool 1 but it still doesnt work

@phaedrux

thats how the heater output is wired e0

[Anvil]

@phaedrux

and this doesnt define heater 1 as tool 1?

; Tools
M563 P1 S"Nozzle" D0 H1 F0 ; define tool 1
G10 P1 X0 Y0 Z0 ; set tool 1 axis offsets
G10 P1 R0 S0 ; set initial tool 1 active and standby temperatures to 0C

[Phaedrux]

It's typical to have the bed heater defined as heater 0 and extruders after.

The first tool should be tool0.

Leave your wiring as it is, and change your config like this

; Tools
M563 P0 S"Nozzle" D0 H1 F0 ; define tool 0
G10 P0 X0 Y0 Z0 ; set tool 0 axis offsets
G10 P0 R0 S0 ; set initial tool 0 active and standby temperatures to 0C

Then at the bottom of config.g add T0

@phaedrux

should i change my heaters m950 values to reflect accordingly?
like delete the T0 from the bed m950 and change the nozzle m950 to T0?
or just delete those values all together from that heater section of the config?

[Phaedrux]

No, leave the heater section alone. Just change the tool definition.

[Anvil]

@phaedrux

ugh dangit. Nada.

and you're sure the nozzle T1 and bed T0 in the heaters section aren't affecting that?

[Anvil]

@phaedrux

Ok so I was just starting to feel like it may somehow be a bad heater core and I plugged in a new rapido hotend just to at least rule it out. And it worked!!

No idea if it sent it to the moon on initial test and burned the heater core out or something but It appears to have just been the heater itself!
Sheesh!

@anvil i did say check it with a multimeter....

@jay_s_uk haha yaaaaa. crud
