    • RE: Successful: Print Queue and Automated Print Cycle

      How-to Print Queue and Automated Print Cycle

      Machine: Prusa-Style machines with heat bed, using Duet Controller is convenient e.g. Prusa MK3, Cetus MK3, MakerGear M2
      Bed Surface: Clean Glass using Isopropyl alcohol (I use Ikea LOTS mirror because of the quality and availability)
      Filament: Tested working with typical PLA, PETG but should works with any materials which can be print on the glass surface and removed easily.
      Model Size: Base 10x10cm (Width x Length) or bigger, Height: 2-3cm shorter than the maximum height of the machine.

      The important aspect for the removal process is to lift the model up vertically instead of pushing horizontally. There's some strong force, that I feel like the vacuum, which prevented the model to move if push from the sides even if it was once removed. From my tests, I can only remove small models if push horizontally which also stress the gantry a bit.

      Instruction:

      • Leveling the bed Manually level the bed or using manual/auto mesh bed compensation and make sure you get a good first layer adhesion, while it is not too squished or too high.

      • Add sprue Add 1mm cylinder in the model to an area that can be cleanly cut or easily broken off when the print finished. It can be added within your slicer software without modifying the original model. The sprue height should be 10-20mm higher so the model doesn't touch the heat block when ejecting. The tip of sprue is the area where the nozzle will be stopped.

      • Test print We will simulate some ejection steps first. The test model should be around the same footprint of your target model, with at least 1-3 mm thick so it is not flexible. e.g. 15cm x 15cm x 3mm rectangular plate. Test printing your model using the right temperature for heat bed, which doesn't warp your model or make it too sticky to the glass, then wait for the model to cool down after finished printing. Try pulling the model up vertically from the sprue, which should take only a little hand force to do if the first layer height is correct. Pay attention to the waiting time and the temperature that the model can be removed successfully because this is the value that you will be used in your ending script of the print. e.g. printing PLA at 60c heated bed, and the model can be successfully removed when the heat bed go down to 32c (which takes 5 minutes from 40c ... Duet's M190 command monitor the bed only when it is over 40c ).

      • Create End.g Macro This is the end script which will be called at the end of your model gcode, the essential steps are:

      ; ###Cool down###
      ; Wait 120 Seconds for nozzle to cool down to under the Glass Temperature of material e.g. My PLA is 60 Celsius
      G4 S120
      ; Wait for Heated Bed to Cool down to 40 celsius
      M190 R40
      ; Wait 600 Seconds for the heat bed to cool down to 32 celsius e.g. My PLA can be removed easily from the heat bed when it reach 32 celsius
      G4 S600
      ;###Lift up###
      ;Set relative positioning
      G91
      ;Move Z up 20mm, the nozzle will pull up the model effortlessly
      G1 Z+20 F1000
      ###Drop the model###
      ;Move X,Y to edge of print bed, choose the suitable X,Y values for your printer
      G1 Y-999 X999 F1000
      ;Heat the extruder to 200 celsius, so the PLA at the nozzle tip melts and the model drops from it around the corner of the heat bed. The model should fall to the table by gravity if placed the sprue at the other corner (Adjusted the location to suited your machine)
      M109 S200
      ;Extruder heater off
      M104 S0
      ###Push the model outside printing area###
      ; Slowly push the model out of printing area, this should be carefully planned if the model has an irregular shape. It can be easier if you have a mechanical push part on X/Y and set up the printing area to facilitate the ejection process.

      • Test End.g Macro Test your macro and refined it before use is a good idea. You will actually see how thing works at this time.

      • Create trigger2.g Go to System directory using System editor in your Duet Web Control and create trigger2.g (2-9 will do) and add this:

      ; Switch off trigger2.g
      M581 Z S-1 T2 C
      ;Wait for current moves to finish
      M400
      ;Wait 10 Seconds (can be omitted or changes)
      G4 S10
      ; Print a.gcode, this is your xxx.gcode in your SD card to be printed
      M32 "0:/gcodes/a.gcode"

      • Create CallTrigger2.g Macro

      ; Set up trigger2.g
      M581 Z S0 T2 C0
      ; Execute trigger2.g
      M582 T2

      • Test CallTrigger2.g Macro Test run your macro, it should start printing a.gcode now.

      • Putting them together Go to your slicer, loaded your model, add sprue, finish settings and put End.g and CallTrigger2.g in the ending script by adding this 2 lines:

      ; Run end.g macro
      M98 P"/macros/End.g"
      ; Run CallTrigger2.g macro
      M98 P"/macros/CallTrigger2.g"

      • Save the file The file name should be the same as one in CallTrigger2.g, in this example is a.gcode

      • Print them Congratulation! Now your printer should print a.gcode repeatedly without manual removal process .. with glass-like finishing at the bottom side ☺

      You can continuously print only one or many sets of model by using more triggerX.g files e.g. a.gcode call trigger2.g which print b.gcode, b.gcode call trigger3.g which print c.gcode and so on. Named the folder and copy that trigger set to /sys when you want to print them. This way, you could have many print sets with a limited number of triggerX.g.

      Also, triggerX.g can be changed, modified without stop printing until the filament run out. You can print set A two times, then set B four times and so on with some planning, a webcam and come back a few times to delete, copy/paste trigger sets in Duet Web Control.

      Notes:

      1. The process was simplified, to make it easier to understand.
      2. Now you get the idea, So, you should customize/modify and test your processes e.g. nozzle priming, heat bed temperature, removal, ejection that suitable for your machine before you begin your production run.
      3. I think the process is not restricted to Duet only. With some more researches and knowledges, other controllers and firmwares should be able to do it too.
      4. I'll add more videos, photos and details later on..
      5. I'm curious what is the biggest footprint area that this method works because I don't have big printer. Please post it, if you tried it succesfully with big prints.

    • RE: Possible Reprap Configurator Bug

      @chrishamm I already found that the problem occurs only when I loaded an existing configuration, which was previously saved with heated bed 'unchecked'.

      Also, I've noticed that the Semitec 104-GT2 value is confusing. The preconfigured in RFF is β: 4388 K while the Wiki stated it is 4725 K here.

    • RE: Successful: Print Queue and Automated Print Cycle

      @dc42 said in Print Queue and Automated Print Cycle:

      BTW I think there may be an indirect way to have one print file start a different print at the end. Instead of using M32 directly, you would use M581 to set up a dummy trigger and M582 to check and execute it immediately. Then put the M32 command in the trigger file.

      Thanks, seem like it's works! Now, I've tested that I could do recursive call between a.gcode and b.gcode by:

      1.) Create trigger2.g and trigger3.g in "sys" folder.

      1.1) Trigger2.g

      ; Switch off trigger2.g

      M581 Z S-1 T2 C0

      ; Print a.gcode

      M32 "0:/gcodes/a.gcode"

      M400 ;Wait for current moves to finish

      G4 S2 ;Wait 2 Seconds

      ; Call trigger3.g

      M581 Z S0 T3 C0

      M582 T3

      1.2) Trigger3.g

      ; Switch off Trigger3.g

      M581 Z S-1 T3 C0

      ; Print b.gcode

      M32 "0:/gcodes/b.gcode"

      M400 ;Wait for current moves to finish

      G4 S2 ;Wait 2 Seconds

      ; Call Trigger2.g

      M581 Z S0 T2 C0

      M582 T2

      2.) Create a Recursive.g in "macros" folder which called Trigger2.g

      M581 Z S0 T2 C0

      M582 T2

      3.) Run the macro and the machine go in an infinite loop of a.gcode and b.gcode

      Now, seem like I can chain many triggers into this loop. I'm testing more to see if it really works with actual printing files or not ☺

      Updated: It's really working nicely .. by just call a trigger, which there's a M32 command in it, at the end of gcode. The nice thing is you can change the macro or trigger any time without stop printing.

      Finally, I'm really happy that this project to becomes fruitful. It takes me more than a year in gathering info, research, learning, pick the right products and putting everything together.

      Of course, Duet is the most important part which realized it! ✌

      I will wrap up and update the process after finished testing with PETG.

    • RE: High power fan with Duet 2 Wifi.

      @Phaedrux Thanks a lot. After reading a bit and looking at the board, it seem to be 32V DC mini blade fuse like these right?

      Now I can get spare fuses. Interestingly, a small 1A fuse is not available to buy on Digikey. Could get from somewhere else anyway 🤗 🤗

    • RE: High power fan with Duet 2 Wifi.

      @Phaedrux It's a bed cooling fan.

      I've read them now but still not sure because I've no background in engineering.

      Also, after hours of research. I've found another high efficient alternative which is rated 1.49A. It's NMB 12038VA-24R-GA-00

      So, I think 2A fuse is acceptable because other fans are smaller .. but a lot cheaper anyway. Anyway, this fuse size is the Ampere of all running fans in the system and which I could buy typical car fuse and replace it right?

    • RE: High power fan with Duet 2 Wifi.

      Hello,

      Thinking about another simple solution within 1A limit, the fan pressure become half of that high power one. The current for this fan is 1A with maximum 1.5A

      This fan will run about 5-10 minutes at a time. Will it be too stretch for 1A fuse?

    • High power fan with Duet 2 Wifi.

      Hello,

      I'm getting a high power fan to be used with Duet 2 Wifi. The model is Delta PFB1224UHE 24V 2.4A 12cm. Is this fan supposed to work with this board? Any caution since I never installed this much power fan before.

      Also, I've read the wiki that there's brushed and brushless motor. Any idea which one is this fan?

      Here's the PDF spec of this fan on official website
