    • RE: How to PID tune dual heater cartridges wired in parallel?

      @hackinistrator ok, I tried with M303 H2 P0.3 S220. Took another minute to heat up but it was even more accurate this time, and did not fail.

      M307 H2
      Heater 2 model: gain 863.9, time constant 606.6, dead time 7.7, max PWM 0.30, calibration voltage 0.0, mode PID, inverted no, frequency default
      Computed PID parameters for setpoint change: P16.3, I0.239, D87.7
      Computed PID parameters for load change: P16.3
      
      Warning: Heater 2 appears to be over-powered. If left on at full power, its temperature is predicted to reach 888C.
      Auto tune heater 2 completed in 748 sec
      Use M307 H2 to see the result, or M500 to save the result in config-override.g
      
      Auto tune phase 3, peak temperature was 228.4
      Auto tune phase 2, heater off
      Auto tune phase 1, heater on
      M303 H2 P0.3 S220
      
      Auto tuning heater 2 using target temperature 220.0°C and PWM 0.30 - do not leave printer unattended
      

      So, I will set heater 2 in config.g to read:

      M307 H2 A863.9 C606.6 D7.7 S0.3
      

      I should be able to print now.

      Thank you!

    • RE: CoreXY randomly losing motor direction

      Problem solved!

      It turned out it was indeed a loose or broken wire crimp connection on the stepper's blue wire, right at the Molex connector.

      I'm amazed it printed properly for as long as it did...

      Thanks for all the help.

    • RE: DHCP

      My mistake, I misread the description of firmware I found on Google and installed duet2combined firmware. Was supposed to install the "reprapfirmware" for my 0.8.5 instead. D'oh! Problem solved.

    • RE: Duet 0.8.5 Ethernet not working after erase + reset (solved)

      I understand now,

      https://duet3d.dozuki.com/Wiki/Firmware_Overview#Section_Duet_Generation_1_Duet_06_and_Duet_Num_085

      *Duet Generation 1 (Duet 06 and Duet 085)
      Firmware files for older boards are currently also at https://github.com/dc42/RepRapFirmware/r....

      The main firmware is RepRapFirmware.bin
      The web interface is DuetWebControl.zip*

      I think I may have been following different set of instructions, thanks for your help elmoret

    • RE: 24v 40watt cartridge can't keep up

      The 60 watt heater worked like a charm! The heater has no trouble keeping up now. The board didn't even seem warm while running the 60w cartridge heater. It's ready to print at 340 Celsius in less than 30 seconds and has no trouble maintaining temperature, even without a silicone sleeve.

      I guess I'll save the "dual 40 watt cartridge heaters wired in parallel" trick for when I get around to running 6mm filament/3mm nozzles (should be soon).

      @Phaedrux Yes it's direct, I'll look into gear extruders

    • RE: Homing direction reversed after firmware update

      @dc42 I see. I had upgraded from 1.21.2 to 1.22.6, FWIW.

    • RE: Homing direction reversed after firmware update

      Upon closer examination, X and Y axis are correct but their directions are wrong. Z is unaffected.

      I changed the stepper direction in config.g from:

      M569 P0 S1 
      M569 P1 S1
      

      to:

      M569 P0 S0
      M569 P1 S0
      

      Since P0 and P1 are the steppers attached to the X and Y axis (on my machine). Now it's working properly.

      @droftarts said in Homing direction reversed after firmware update:

      @Duetfan223 I think that gotcha is in the firmware release notes https://github.com/Duet3D/RepRapFirmware/wiki/Changelog-RRF-1.x-&-2.x#version-121 but I can’t find it right now.

      I see now, thank you. I'll keep that in mind next time I encounter strangeness.

    • Homing direction reversed after firmware update

      My config.g files and homing files seem unchanged. I have a CoreXY machine running off a 0.8.5 board.

      I was running 1.21.2 and upgraded to 1.22.6. For now I will change the homing direction in home_.g files to compensate for this.

      Has anyone else experienced this behavior before?

      @dc42 @hackinistrator said in How to PID tune dual heater cartridges wired in parallel?:

      @Duetfan223 i'm glad that it works , but honestly i don't think that its the right solution .You don't really need that second heater .

      I have been running a 24v 50 watt cartridge heater on the regular E3D Volcano and can't seem to heat the plastic as fast as I'd like. It's likely a pitfall of using 3mm filament. The SuperVolcano seemed like the logical next step but the standard 24v 80 watt heaters are out of stock. They're nearly 48mm long and I assumed part of the "magic" was having heating elements the whole length of the heater block.

      So that's why I decided to go with two 50 watt heaters for now, and I'll buy the 24v 80 watt whenever that becomes available. I had figured I'd set these 50 watt cartridges to S0.8 PWM for "80" watts but I guess it doesn't really work that way?

      I still have a lot of 3mm filament I'd like to use up before switching over to 1.75mm. I'd imagine the smaller filament will solve a lot of the problems I've been having with the filament being unevenly heated at higher print speeds.

      2.85mm "bargain basement" PLA, 1650 mm/min at 230 temperature. Notice the "pulsed" affect the filament has on the far side of this print? Is that the heater switching on/off for PID? I updated the firmware and I'll run Auto Tune a few more times. Takes FOREVER to cool down with that sock on there... but that's a good thing, right? 🤠

    • JavaScript error updating 0.8.5 firmware via web interface

      Hello

      Was running firmware 1.21.2 on a Duet 0.8.5 and decided to update to the newest version, to see how it affects tuning hot ends... I downloaded the RepRapFirmware.bin from this release:

      https://github.com/Duet3D/RepRapFirmware/releases/tag/2.05.1

      And proceeded to update via web interface.

      The firmware seemed to update and under settings, the General tab show Firmware Version 1.26.1 (2020-02-09B1)

      The interface gives an error though and disconnects from the machine immediately:

      JavaScript Error

      A JavaScript error has occurred so the web interface has closed the connection to your board. It is recommended to reload the web interface now. If this happens again, please contact the author and share this error message:

      Message: Uncaught TypeError: Cannot read property 'current' of undefined
      URL: http://192.168.1.7/js/dwc.js
      Line: 1813:27
      Error object: {}

      Any ideas? I power cycled the board after waiting about 5 minutes, and it still gives same error and disconnects immediately

    • RE: How to PID tune dual heater cartridges wired in parallel?

      @hackinistrator said in How to PID tune dual heater cartridges wired in parallel?:

      maybe try M303 H2 P0.5 S220

      That seems to help, this time the overshoot was only 13.3 degrees.

      Warning: Auto tune of heater 2 failed due to bad curve fit (G=1505.2, tc=605.4, td=7.5)
      11:14:53 AMAuto tune phase 3, peak temperature was 233.3

      So I have adjusted config.g to:

      M307 H2 A1505.2 C605.4 D7.5 S0.5
      

      If I run M303 H2 S220 command without a P parameter, does it default to 1.0 or does it use the values saved in M307 H2?
