    • RE: Recommendations needed on mounting extruder

      @Rushmere3D @droftarts @achrn

      Just wanted to close off this thread. Thanks for all the help and suggestions. I ended up using a Revo Voron + Orbiter v2 and modified Mini-AfterSherpa toolhead. In its current setup it has reduced my print volume slightly but will modify more if I find i need more print area.

      It is still a bit of mess re:wires but seems to print well.

    • RE: How to cancel loading/unloading of filament?

      @OwenD

      Thanks! I updated to release 3.5 and this approach seems to work well.
      Is there a reason you used M99 over abort?

      Edit:
      If I understand correctly M99 works better here as it does not cancel the current print file. Whereas abort would.

    • How to cancel loading/unloading of filament?

      tl;dr; The move.extruders[].filament value updates even if the macro fails to complete.

      Issue #437 on Github discusses this and it seems the recommended approach is to add a T-1 before any abort command. However, if the user selects "Cancel" after running M291 P"<message>" S3 there does not seem to be away to set the tool to T-1

      Would you have to do something like this?

      T-1 ; disable tool
      M291 P"Feed filament?" S3
      T0  ; reset tool
      

      Is setting T-1 still the recommended approach?

      Any help on this would be greatly appreciated.

    • Tuning Extrusion Multiplier / Flow (Inspection pointers)

      I have been following Ellis' brilliant print tuning guide and have got a bit stuck on how to determine what is a good Extrusion Multiplier. The guide says a good Extrusion Multiplier will be noticeably smoother on the top surface and provides some examples.

      I have printed examples with an Extrusion Multiplier of 92, 96, 98, 99 and 100 (see below images) but to my untrained eyes and hands they are all pretty much the same (It doesn't help that the filament is white).

      Could someone please help point me in the right direction?

    • RE: Recommendations needed on mounting extruder

      @droftarts Thanks for the information! This is very helpful, I will see if I can reuse my current mount.

    • Recommendations needed on mounting extruder

      I have been running a Cetus 3D MK2 on a Duet Maestro for several years now and it has been working great. Its come time to replace the extruder and hot-end. This is what it looks like (image take from the internet):

      alt text

      I plan to replace the extruder with an Orbiter 2.0 and the hot-end with a Revo Micro. The part I am trying to figure out is the mounting.

      Are they any existing toolheads or mounts that I can use, modify or get inspired from to help with this replacement?

    • RE: nozzle not primed after retraction (I think..)

      I was able to get the first layer test to print full squares by reducing retraction speed (15mm/sec), retraction distance (0.5mm), layer-height (0.2mm), extrusion width (0.48mm) and increasing travel moves (260mm/sec) and pressure advance (0.7). This also helped with printing the single parameter geometries.

      I think I still have a while to go to dialing this in but I will take it as progress. Thanks for all the help.

    • RE: Stealthchop2 to Spreadcycle switch

      @CCS86 did you manage to find a solution for this? I experience the same thing with my maestro. For now I have disabled stealthchop2 but would love to use it as it makes my printer very quite.

    • RE: nozzle not primed after retraction (I think..)

      Thanks @Phaedrux

      I have been using the macros you created to try tune the retraction (Thanks for creating them, they have helped a lot).

      My setup is using a direct drive and slicer is configured to retract on travel and layer changes. Travel speed is 130mm/sec. I turned off PA and focused on retraction tuning. So far the results are pretty poor. The only time I can get enough filament down at the start of new layer is when I re-prime at set it something greater than 0.68.

      I am going to run some more test this evening.

    • RE: nozzle not primed after retraction (I think..)

      I tried slowing everything down and the results were near identical to the above picture. You can see as the extruder retracts and moves to the next geometry and then de-retracts it just pushes out small blobs with spaces between them. It then seems to sort it self out after a little bit. I am not sure how else I can debug this.
