@dc42 Just to close this topic, RatRig seems to confirm they got a bad order of 4028 fans which were really 003's labeled as 001's. So here i am thinking i'm crazy or wiring incorrectly. Anyone who reads this in the future maybe will have an easier time!

@RogerPodacter said in Dual Markforged Kinematics Setup:

M669 K1 X1:0:0:0 Y10:1 Z0:0:1:0 U0:0:0:1; Matrix mapping for Axis - X:Y:Z:U

i solved my issue. maybe this helps someone in the future. i simply changed the Y matrix:

old

M669 K1 X1:0:0:0 Y1:-1:0:1 Z0:0:1:0 U0:0:0:1; Matrix mapping for Axis - X:Y:Z:U

new

M669 K1 X1:0:0:0 Y1:-1:0:-1 Z0:0:1:0 U0:0:0:1; Matrix mapping for Axis - X:Y:Z:U

@RogerPodacter nevermind, i solved the issue by looking at the latest documentation: Gcode Meta

the echo command cannot have a space after the >.

Fixed code:

while true
    if state.status == "processing"
        if exists(global.runtime)
            set global.runtime = {global.runtime + 10}
            echo >"runtime.g" "global runtime = " ^ {global.runtime} ^ " ; AUTO GENERATED by daemon.g"
    G4 S10 ;wait 10 seconds.

@rogerpodacter here are my new specs. side note i used the format tool but it did not let me chose a cluster size, but it so happened to default using 32kb cluster size so that's good.

after only a few minutes, my DWC web interface is much more responsive. I will test a print nextl.

SD card in slot 0: capacity 7.95GB, partition size 7.94GB, free space 7.69GB, speed 22.50MBytes/sec, cluster size 32kB

@dc42 Thanks, that makes it clear. I have no need for that particular SD card slot. I just wasnt clear if there was some other advantage, but i obvioulsy use Wifi for all my Gcode file uploads:)

I used the input shaper plugin, recorded motion with no shaper, then recorded motion with each of the other shapers activated, then i can compare. I have obvious spikes on my chart.

Your chart has literally no spikes at all. It would indicated you dont have any frame or belt issues with your printer, but i've never seen this. even the best printers still yield a peak resonance frequency. are you sure your accelerometer is tight, and at the proper location as close to the nozzle as possible?

@phaedrux yes so far today since i've done that it seems perfectly reliable. so it very likely could have been my computer causing this issue.

I guess a side note, only the DWC tab seems to grow in resources, its probably the console log constantly running...

@Phaedrux i did not get a chance to try these steps, but i think i am on the latest firmware.

i thought more about this and remembered in the last few days i added a liquid cooling pump, the standard PC type using 3 wire 12V 0.8 amp. the tach wire goes directly to the Duet board out4.tach, and the 12V and ground goes directly to a dedicated power supply.

once i removed this tach wire, this issue disappeared. this doesnt make sense why this would matter. when the printer did boot up, the pump RPM's gave a normal reading in DWC. so it worked correctly. but i guess something was causing a glitch with this setup.

12V+ - dedicated PSU
Ground - dedicated PSU
Tach - Duet board out4.tach

but i have my config as follows. perhaps i should remove the first portion out4?

M950 F5 C"out4+out4.tach" Q500

@fickert i had similar issues and i solved it nearly completely by increasing motor current. i would run my CoreXY motors at 1.4 amps using TMC2209 drivers, and these motors are rated 2.5 amps/phase. I raise the current to 2.0 amps, and the motors quieted down almost completely.

WARNING i had to add active cooling to my mainboard! My drivers overheated quickly until i added a fan on the mainboard. I use the Duet 3 Mini 5+, and a simply 4010 fan blowing across the driver chips keeps the board at around 39C. I added the fan to temperature control of the MCU temp, so the fan kicks on automatically when the board gets hot.

@jay_s_uk thanks, i think that fixed it. final gcode:

M308 S2 P"temp1" Y"thermistor" A"Chamber 1 Upper" T100000 B4725 ; Define Sensor as Chamber temperature
M950 H2 C"out1" T0 Q10												; Define dummy Heater2 and spare pin as the heated bed, bind to Sensor0
M307 H2 B0 S1.00                             ; disable bang-bang mode for the chamber heater and set PWM limit
M141 H2                                      ; map chamber to heater 2
M143 H2 S120                                  ; set temperature limit for heater 2 to 60C

M308 S3 P"temp2" Y"thermistor" A"Chamber 2 Lower" T100000 B4725 ; Define Sensor as Chamber temperature

@dc42 yes precisely, that is what i thought. but now that i just looked closer, its a bit different. the H4 thermistor which is my "working" example is actually on one of the toolboards 1LC 20.temp1, not on the mainboard as i thought. so it seemed that my H4 thermistor could control a fan on a 3HC or a fan on the mainboard. however now that i am on v3.4.5, it appears that H4 is no longer working for either of them. now i'm very confused or perhaps the underlying code has changed in the new firmware.

i guess just ignore my topic at this point because i am confused. maybe there was a CAN bus thing which allowed the toolboard but not the 3HC to control over CAN bus, but none seem to work now so its ok.

my original intention was to use the daughterboard thermocouples and have TC0 control a fan on the mainboard, and TC1 control a fan on the 3HC.

thanks all, unfortunately the issue remains. i've upgrade all components to 3.5.0 beta 3, but it just seems that a fan running from a 3HC wont accept thermocouple sensor from a Mini 5+. i dont know what else it could be. the best i can understand is a thermocouple on the mainboard cannot be used as a sensor monitor for a fan on the 3HC. but thermistors work fine, so its something related to the daughterboard perhaps.

@Phaedrux both are reading 21.6 and 21.7. these TC's have been in use for many months. the only difference is i have now added a 3HC trying to use the fan. so its definitely a config.g setup issue.

it allows me to use my hand heat to trigger 30C and challenge the fans easily.

to be clear the mode is on or off, so there is no variable temperature gradient. using H4, the fan turns on at 30C. using H15 or H16, the fan runs 100% non-stop.

@RogerPodacter there must be some conflict with how i have my fans setup. when i change H16 to H4, the fan works just fine. but when using H16 as a sensor monitor, it runs 100%.

if i set both fans to H-1, both work normally and i can manually control them with 0-100 slider bar.

@chrishamm update: today this SD card died permanently. so it was in fact beginning to fail.

the SD card is the one which came with the Duet 3 Mini 5+ which i purchased in Sep 2022.

@Phaedrux yes the 3HC is address 1 default.

@RogerPodacter to add more details, if i physcally swap the 2 fans, the 3HC continues to run 100%. so the fans hardware are ok, its something wrong with the configuration or the sensor number assignments etc. whichever fan is on the 3HC, that one doesnt work.

@Phaedrux i dont see any related errors. i have to resolve my Daemon issue.

I am testing 2 fans and having strange trouble. I cant get the config.g setup properly.

I have a 4 pin PWM fan connected to a Duet 3 Mini 5+ monitoring sensor 15, and i have another 4 pin PWM fan connected to a 3HC monitoring sensor 16. both 15 and 16 are a thermocouple board on the mainboard.

the strange thing is that if i set either of these to monitor H4, the fans work just fine and turn on when proper temperature is reached.

works fine

i'm confused. even though these are being shared across CAN bus, it sometimes works and sometimes does not.

@Marius-Breuer i run a 12 volt Noctua fan connected directly to the 4 pin with no issues on a 3HC and a Duet 3 Mini 5+.

I dont recall that i had to change any wiring to make things work.

My fan is the Noctua NF-F12 industrialPPC-2000 PWM.
