@adalton5683 This doesn't look right either, you map heater 0 (bed) to sensor 1 (hotend):
M950 H0 C"out0" T1it should be T0 to make sense.

this should be S0 not S1
The S value is the sensor number. You can't have 2 S1's!
https://duet3d.dozuki.com/Wiki/M308 -
@jay_s_uk seems like you just told me to change it to S1 lol
-
@adalton5683 the other one! you have 2 M308's and I highlighted the second one, but instead you changed them both
-
@jay_s_uk ok I made that change
I think I moved my config around after the original post and I think I made that change so it was the only one that was like that to change. anywhoo heres the current c.g

Does your hotend temp still show -273?
@adalton5683 said in ZERO KELVIN HOTEND TEMP:
M563 P1 S"HotEnd" D0 H1 F0
This should be P0 for tool0. P1 would be for tool1, which I assume you don't have two tools.
Are you assembling this by hand or are you starting with a config from the online generator? https://configtool.reprapfirmware.org/Start
Can you send M98 P"config.g" in the gcode console and report back what it returns? That will check the config for any syntax errors that may get missed during startup.

@adalton5683 your heater and sensor config looks OK to me now. However, your bed heater has faulted. This is probably because it is a slow bed heater and you tried to heat it without tuning it first. I suggest you restart it and see whether the bed heater displays a valid current temperature before you try to heat it.

@dc42 so ive restated it many times and its not shown the correct temp. ive tried deleting everything in config-overrid.g and anything that has to do with tunig if it appeared in config.g
so essentially im starting with a fresh install and its showing -273 still
-
@adalton5683 If you are sure that everything is configured correctly but you are still seeing-273, then did you read my post above (27th Jan @ 07:41) ?
-
@deckingman I think our timezones are off so I cant find a post at that time. so can you specify what post.

The first post after your opening posts.

@deckingman
Ok yeah I’ve already check that. The meter is giving me correct resistances on the therm. I did however order a new thermistor anyway just incase. Also checked and rechecked the crimps even checking their resistance. -
@adalton5683 try sending M308 S0 from the console with no other parameters. It will report the current parameters for sensor 0 and the last error recorded.

@dc42 I ran both S0 and S1
also my replacement thermistor arrived so I installed it, just the clipped end.
-
Can you switch from temp1 to temp2 connection on the board and update the M308 to reflect?
M308 S1 P"temp2" Y"thermistor" T100000 B4725 C7.06e-8
Does it still show -273?
Can you make up a much shorter lead for the thermistor to see if it's a break in the wiring?
-
1000 Thanks to you my friend! Your fix did not work bc i didnt try it but it did lend itsself to me finding my hot end thermistor plugged into out6 like a fan when I went to try it. I have no clue how it got there.
looks like its always anoob mistake .

So to to the devs, how well does this board handel CNC? ive got a couple CNC builds going rightnow and I ended up buying another one of these boards since I thought I toasted the heater/driver. So I will probably use this second board for a smaller 3 axis NEMA 17 cnc machine. hoping to power mostly everything but the spindle from it if possible.
I heard there is a CNC firmware. whos the main guy on that project?
My other build is a 12Nm NERMA34 4 axis, w/5hp spindle running with 110V in planning on using a rotary phase converter to hopefully get all 3hp out of that spindle. Im assuming this board cannot supply 6A ish per stepper right?
-
@adalton5683 Probably best to ask your CNC question in a new thread in the CNC forum for some more visibility.
