IMPORTANT ISSUE with bed temp controller
-
I know that sometimes the relay/SSR used can have unintended behaviors if not properly accounted for, they can "latch" on if too warm or if not properly configured. If you're able to provide part #'s for the relays and some pictures of wiring, etc, That could help evaluate the issue.

well are you running in SBC mode or standalone for starters?

@Luke-sLaboratory Yea it is the first thing I looked at. wasn't the case.
-
@jay_s_uk sadly SBC mode.. I know it isn't the most stable but it is the only effective way for us.

seems odd to invert an output
and you have no frequency set which means that SSR/relay would be running way faster than is good for itOwns various duet boards and is the main wiki maintainer for the Teamgloomy LPC/STM32 port of RRF. Assume I'm running whatever the latest beta/stable build is

Can you provide the contents of /var/logs/syslog for the day it happened on?
May be something of interest in there...Owns various duet boards and is the main wiki maintainer for the Teamgloomy LPC/STM32 port of RRF. Assume I'm running whatever the latest beta/stable build is
-
@jay_s_uk not a programmer here.. but I figure it is inverted because of the "!" ? Ill check that out.
-
Wait - this means that to have the bed be "off" - the duet needs to run with out3 "on"
so if the duet doesn't send signal (or if a wire gets cut, loose, etc) the relays will be turned on?
Otherwise, yeah, the frequency thing is definitely a non-recommended setup as well - Could @jrockland confirm that they're SSR's and not "traditional" relays?
-
@jrockland Yes - the ! is to invert the signal, in this case, for the duet to turn "on" the expected output, it needs to turn "off" the on-board output.
-
which definitely isn't very fail safe...

i would suggest that you connect it to out0
-
@jay_s_uk Agreed, this makes me anxious
-
@Veti said in IMPORTANT ISSUE with bed temp controller:

doesn't really matter in this case as its using an external relay
-
@Veti Depending on the actual thermistors they could be, but having all 3 be identical is suspect for sure! - would need validation to be 100% sure. For relay outputs, any output is fine, I prefer to use a connectorized output for my SSR ones.
-
B4138 thermistors have not been used in years. so its very unlikely that its correct.
-
@Veti Fair, I have some in a cabinet somewhere as a backup to my backup's backups.

Jan 14 02:04:45 raspbMy take from this is that it shut down the duet after 10 min of heater fault, and if the relays need a high signal to turn off, by having no signal (from a shut down duet) it just stayed on and caused the issue.
