    • RE: Pressure Advance Calibration

      Im still quite a newbie in this realm and i guess the amount of variables are getting to me šŸ™‚

      Backstory is I have a zesty nimble, which worked amazing but had 2 issues I cannot solve

      1. Ripples in the surface finish - Company is still working on a fix
      2. blobs at the end of a layer creating terrible Z seam scars

      Tried all the ideas such as coast and wipe, but they have their own issues such as only available in some slicers, cannot be used with firmware retraction, etc.

      Pressure advance by the sounds of it should eliminate the blobs at end of layer, but any attempt to use PA with a nimble due to its required low jerk values caused my prints to slow to about 3x the time. Was painful to watch.
      Although, with the nimble I was able to get a great calibration part from the above enclosed script.

      0_1555794438938_Nimble PA 1.jpg

      With the nimble, the calibration part has easily discernible reversing thick areas, and one can find the "best" setting of 0.12, but pressure advance was unusable for me in combination with the nimble.

      So I order a Bondtech BMG and use a capricorn bowden tube of about 650mm paired with an E3D 0.9 degree stepper.

      Now i get the Esteps all setup at E808, run some retraction calibration parts, and i still get blobs due to pressure at the end of a layer.
      Run the above scripts on a Pressure Advance test and..... The results do not make sense to me.

      Before the extruded line ever gets to an optimal state, the extrusion is messed up. It gets to the point where nothing is coming out of the nozzle at all. I was at 5-100 print speed so ran again at 20-80 which is the speeds I actually print at (E3D volcano, 0.6mm X nozzle)
      And again the part never gets to the optimal PA value without the PA settings making the filament retract so much it doesn't print.

      What am i doing wrong? Any suggestions?

    • Confusion on multiple Probes RRF 3.2

      in the patch notes it states :
      "If you configure a Z probe using multiple M558 commands instead of a single one, you must make sure that only the first one has a P parameter. This is because M558 with a P parameter now sets default values before processing the other parameters of the M558 command."

      My Config file has the following. :

      ; Z probes
      M558 K0 P8 C"^zprobe.in" T18000 A5 H5 R0.2 S0.01 F600 B1 ;
      G31 K0 P500 X0 Y25 Z2.557 ; inductive probe offset,

      M558 K1 P8 C"^zstop" T18000 H5 R0.2 S0.005 F120 A10 B0 ;
      G31 K1 P500 X0 Y0 Z0.730 ; Z switch offset

      If on the second M558 command I remove the P8, when I do a G30 I get an error message of
      "Error: in file macro line 47: G30: Z probe 1 not found"

      So I do not understand the patch note of only having one with a P parameter, or am I doing something incorrect in my M558 commands ?

    • Blank DWC Page

      uploaded dwc3.11 on my duet 2, and now the DWC is a blank white page.
      Tried 2 different browsers, nada.

      I used the github page, download DWC Zip, it downlaoded as DuetWebControl-master.zip
      Used DWC to upload, and now all white, when i connect via name or ip

    • Recommended Fan Layout for Dual Extrusion

      Im setting up one of my printers with dual extrusion, using 2 separate hot ends.

      So I have 2 hot end fans and 2 part cooling fans. Since i can't have 4 PMW type fans with the duetwifi, its 3 x PMW + 2 x Always-on...
      What would be the recommended setup?

        • put both part cooling fans onto one PMW and the 2 hotend fans on the other 2 PMW.
        • put both hot end fans onto the "always on" fans and control the part cooling fans with 2 PMW fans
      1. an option i have not thought of

    • RE: Recommended extruded motor

      As an update, I went with a Moons 1.8 stepper, 0.46 Nm.
      Works well so far with very smooth looking surfaces so far.

      @frank26080115 Very interesting re the changing of the shaft and having the ripples disappear. I really like the flexible shaft direct drive on a delta printer as it removes the Bowden and doesn't add the motor weight. Next time I get motivated to try it again i'll try your suggestion.

    • Recommended extruded motor

      I have a delta printer, based off of DC42’s large Kossel build.
      Duet Wi-Fi , smart effector, E3D volcano with .8mm nozzle.

      I have been using a nimble extruded but am tired of endless calibration and never ending blobs and ripples. I have a titan extruded sitting in a box so I’m looking at going back to that and a Bowden tube.

      With the nimble it was recommended to use a 1.8 degree motor due to the gearing. What is recommended for a titan and a volcano setting ? 1.8 or 0.9 ? My power supply is 24v if that matters in the decision.

    • PT100 and PID

      Maybe a dumb question but...

      If i use a PT100 on my duetwifi, do i still do the PID process ?
      If so is there any special parameters in the M303 or M307 commands ?

    • RE: Zesty Tech Nimble and retraction issues/re-engaging issues

      I'm just jumping back into this 3d printer adventure, printer being down the last 6 months.

      I have a zesty nimble, and volcano using 0.8 nozzle and am using PETG.

      I have yet to find a good combo of settings to get my prints to where I want.
      I have also just started playing with Pressure advance. Using the calibration print that is in another thread with the python script to adjust it, It tells me I need 0.17 pressure advance.

      This then makes my prints extremely slow, so I have upped the jerk from the recommended 40 to 80 and 100.

      I'm no longer sure the correct methodology for calibration with every new variable.
      The above mentioned print is great for calibrating Pressure advance, but what is a good methodology/calibration for acceleration, and jerk ?

    • RE: Recomendation Extruder/Nozzle

      I have two delta printers, one printer with a titan and one with a Nimble. Both are great, although I prefer the nimble due to ability to use more plastic types (ninja flex) and reduced retraction distance with a direct drive.
