i print 500C easily with a dyze hotend and extruder....works all day long

@engikeneer that happened to me, i did even worse and broke some of the solder points....but is no big deal the pinouts for the duet are well documented and the SDcard is SPI if i recall, so i just followed some traces to make the connection work again...just study the boards circuitry before you do anything else

well on the duet2 i swapped a wifi to ethernet and also the reserved (added wifi to Eth) and it worked just fine in both cases, you will just need to give up that SPI port I think , just use a decent wifi module like ESP12 with some external antenna and give it a shot, unless they went as far to the effort of removing wifi support native from RRF3

@dc42 RepRapFirmware for Duet 3 MB6HC version 3.01-RC5 running on Duet 3 MB6HC v0.6 or 1.0

the max retraction speed for the Dyze is 25mm/s , but i will try the other settings....i can always go higher than 25 but am sure will be clogging time

ok yup the M143 H0 P0 S150 did the job, all is well......RRF3 keeps playing tricks on me

wouldnt optical anything be a problem given we usually dont have printers in a super clean area? I mean mine isnt dirty, but sure not dust free....
my home water treatment system used an optical sensor for something (forgot what it was) but it used to go out like once every 6 months....it uses something else now.....

i have ran as high as 150C on my older Duet2 no problem, some materials like ABS need it and I have an A/C bed with SSR relay so it heats up pretty quick....where is the restriction coming from because in my config.g I have the line below, but it doesnt seem to care, it cuts off after 125C regardless.....do I need to move it to another heater output?

M308 S0 P"temp0" Y"thermistor" T100000 B4092 ; configure sensor 0 as thermistor on pin temp0
M950 H0 C"out0" T0 ; create bed heater output on out0 and map it to sensor 0
M143 H0 S150 ; set temperature limit for heater 0 to 150C
M307 H0 A450.2 C282.2 D6.3 S1.00 V0.0 B0
M140 H0 ; map heated bed to heater 0

i havent had an issue with running mine up to 150c and just a chinese sensor, i also have metal plate, glass, copper sheet and PEI and it does ok, printing ABS and other tough materials and the temp readings appear to be correct or I would be having issues

am having issue with stringing too with TPU....can someone clarify how to approach a setting for retraction speed? I know from past experience if I make my Dyze Xtruder retract too fast it will clog....

no luck trying a myriad of M308 figures....so i gave up and ordered a PT100 board and sensor instead....so i would say this thermistor is not compatible with either Duet3 or RRF3 , I just couldnt make it work and dont know if anyone else has (at least not over on the Dyze forums neither)

FIRMWARE_NAME: RepRapFirmware for Duet 3 MB6HC v0.6 or 1.0 FIRMWARE_VERSION: 3.01-RC2 ELECTRONICS: Duet 3 MB6HC FIRMWARE_DATE: 2020-02-18b1

ill try RC3 now

i think the issue is definitely RRF3 related, as more arduino testing confims the Dyze thermistor is working fine ......but as already discussed in other threads, its does a very poor job at low temps....compared to a cheap chinese thermistor...

I am pretty certain it has something to do with warmup time since I notice the Dyze site indicates this parameters for Marlin firmware, but i do not know if this exists in RRF3

#define MAX_CONSECUTIVE_LOW_TEMPERATURE_ERROR_ALLOWED 5
#define MILLISECONDS_PREHEAT_TIME 30000

@dc42 this is what Dyze has on their site for Repetier (thou looks like only v2.x)

https://docs.dyzedesign.com/hotends.html#reprap-firmware

@dc42 yea i removed that and it didnt do anything....still -273 and bombs out when activated.
I know is not the wiring or where is plugged in at because if I plug in a regular thermistor it works right away, so the wiring and port all check out ok, yet the dyze also seems to be ok when i test it with arduino
am stumped....I think i printed enough filament to the moon and back with the Duet2 with this Dyze setup and it never skipped a beat....

@mwolter but the Y axis doesnt matter, as the dual motors can only align the bed across the x -axis, so as long as both Y are the same, it doesnt matter if its 0 or 180....at least how i understood it, and its working ok now.....

its been fine, solved....one of the zmotors was coming loose from the rail....smh

after a few learnings with Duet3/RRF3 I managed to work out all the kinks, but i put on my Dyze Xtruder/Hotend Pro back on and it doesnt like the Dyze Thermistor 500C....
with the gcode command below this thermistor was working great on my older Duet2,

OLD GCODE Duet2
M305 P1 T4606017 B5848 C5.548428e-8 R4700 ; Dyze Hotend THERMISTOR

NEW RRF3 GCODE on Duet3
M308 S1 P"temp1" Y"thermistor" T4606017 B5848 C5.548428e-8 R4700

it just starts with the -273C nonsense and cant turn it on, it faults right away as open circuit....I have tried different T (4500000, etc) settings and B5120 and others and same outcome...

forgot to post i get this message sometimes, not every time i do a G32....but there is nothing wrong with Z offset, it set perfect nearly 0 (0.02)

G32
Warning: the height map has a substantial Z offset. Suggest use Z-probe to establish Z=0 datum, then re-probe the mesh.
9 points probed, min error -0.220, max error -0.056, mean -0.148, deviation 0.056

ok so my new Duet3 w/RRF3 is not bed leveling with dual z's as previous with Duet2....here is my code.....what am i doing wrong?

BED.CFG
M561 ; clear any bed transform
G29 H1 ; Clear bed height map
