As rumored the Voron 2.4r2 has been released with many enhancements and upgrades. You can download the latest release at the official gitHub repo located at https://github.com/VoronDesign/Voron-2/releases/tag/V2.4r2

Use this topic to comment and discuss the updates, let us know what features you look forward to the most! Looking forward to seeing the first "Build Guide" for transition from a V2.4r1 to a V2.4r2!
 

 

(This is a copy of official Release notes found here: https://github.com/VoronDesign/Voron-2/releases/tag/V2.4)

 

VORON2.4 Release
Release Notes:

Release V2.4 of the VORON2 lineup of 3D printers. This release re-focused on simplicity and cost for VORON2, and has been redesigned from the ground up to be more streamlined, easier to source, more fun to build, and generally a better machine to own. In short, what VORON used to stand for.

Notable features for this release:

  • Afterburner Toolhead System, features minimal parts you actually swap, and improved cooling of both hot end and parts. Comes in both Direct Feed and Bowden configurations. We've incorporated all feedback received during the beta testing process and made it much easier to assemble.
  • Direct drive A and B motors allow for smoother belt path and less parasitic loses. Also reduces noise and ringing, while improving machine reliability.
  • Z rails are now centered on the vertical extrusions, allowing use of almost any 2020 T slot profile available.
  • SKR 1.3, along with TMC2209 and 24V bus voltage is now the standard configuration, allowing us to ditch the Astrosyn dampeners while retaining quiet operation. 24V also allows for reduced wire gauge in the chains without loss of efficiency.
  • Increased Y travel. There's now a full 10mm of over-travel on Y axis, allowing one to use the Z nozzle probe without sacrificing build plate space.
  • XY joints and Z idlers now use regular 20T toothed pulleys, reducing complexity and cost, while improving reliability of the machine. Z idlers are also simplified and now use single screw for belt tension adjustment.
  • Z drives now accommodate any metal 80T pulley available on the market, including ones with flanges. Metal 80T improve accuracy over printed 80T pulleys, and allow for more consistent gantry leveling results.
  • New front idlers are vastly simplified and also feature single screw belt tension adjustment. This allows users to get more consistent results when tensioning belts and, more importantly, while trying to match the belt tensions of a group of belts.
  • Part counts and variety has been reduced, and printed parts now require much less plastic.
  • Improved bed mounting using globally sourceable spacers in order to help eliminate bed distortion during the build process.
  • Front panel is now a set of doors, using magnetic latches and print-in-place hinges.
  • Screw-down panel clips from V2.1 return with a re-design and improved installation method. They are now almost as quick as the quick-release panel clips to install and remove.
  • Rear fan housing has been redesigned to help utilize more of the filter material. It now uses a 60mm fan for easier 24V sourcing.
  • Rear plug panel sees the return of the integrated non-filtered mains inlet, which is much cheaper and easier to source. It also features dual Keystone terminal slots for easy port extendability (CAT6, USB, etc).
  • The Mini12864 LCD Module is now the standard LCD for VORON family of printers. It's a lot more compact than the now-ancient RepRap Full Graphics Display and is a lot more responsive thanks its use SPI bus connection.
  • Electronics compartment layout has been improved to allow better cooling and easier component management. DIN3 (35mm) rails are the standard configuration now which bring with it much improved installation and maintenance experience. Electronic compartment cooling is now provided by dual 60mm fans, significantly improving component cooling.

Work on this release began before Christmas of 2019 and the pace of development on it has been remarkable. I hope you enjoy building this machine as much as we enjoyed designing it.

Have printed all the parts for the 2.4 prior to this release and was waiting for the arrival of the sourced parts.

Finally have it and was going to start assembly when this was announced. 

Is there any documentation to the difference in printed parts?

Is a complete parts print required or can some of the 2.4 printed parts be used for 2.4r?

Searched but could not find answers.

Release Notes

This release contains QoL updates and improvements to the official release of the VORON2.4 3d printer.
For more detailed information about V2.4 itself, please refer to the official release notes and the previous update V2.4r1

If you're just getting started with your V2.4 build, the files attached to this release contain the most up-to-date parts required for your Voron 3D printer. If you are currently building, or have already built your V2.4r1, please check the list of fixes and updates below and determine whether you need to update your printer accordingly.

The following fixes and updates have been made since the previous release:

  • MGN12 X Axis setup from Trident (originally member contributed)
    • (note: as with Trident, the MGN12 setup drops compatibility with the PL series of inductive probes)
  • Revised Z drive modules to fit guitar amplifier feet introduced with Trident. Maintains compatibility with compressor feet.
    • Requires a modification to the bottom panel for upgrades from V2.4r1. Cut template included in the tools folder.
  • New rear skirt layout relocating the power inlet and keystone pieces.
  • Most unsupported countersunk bolt holes changed to using the cross-bridge method instead of a chamfer.
  • Panel mount clips from Trident
    • 1mm foam recommended for the top and rear panels
    • 3mm foam for the side panels.
  • Mini12864 display housing from Trident and updated for better compatibility with the BTT version of the screen.
  • Simplified Z cable chain mounts using one screw and a printed retainer.
  • Updated skirt fan mounts using M3 screws and heatsets to mount the fans and fan blanks. Inspiration for the heatset mounting method taken from Ali Express vendor.
  • Revised Z gantry blocks with extra material so the printed part touches the panels before the screw heads.
  • Updated suggested electronics compartment layout to match Trident.
  • Electronics DIN mounting clips from Trident.
  • Updated exhaust filter housing with two screws holding the filter access cover.
  • Added an exhaust filter fan grill to correct spacing for the fan mounting screws.
  • Revised front idlers with tensioning screws moved to be inline with the idler pulleys. Inspiration for this modification taken from Github issue - posted by chrisingham05 (#255 ).
  • Added mount for 3x5 WAGO 221 modules for inlet power wiring.
  • Updated XY endstop pod compatible with both independent and PCB mounted D2F microswitches.
  • Updated pulley jig for spacing assistance on all stepper pulleys and gears.
  • Updated assembly manual to reflect the changes introduced by 2.4r2

I was in the midst of a r1 build when r2 came out. I am taking the time and reprinting things so the first one I build will be r2.  In that vein, I took the above list and added "checkboxes" for the number and progress of my printing. It isn't fancy, but it is just what I threw together so I could transition to r2 easier.  Thanks to Demosth for the original data that I massaged off here. I have attached a PDF and a Word docx file for other people to use.

Just a quick note - the WAGO nomenclature was confusing because of the Voron print quantity marking. Now that I got in the WAGOs and printed the mount, I realized that the 3x5 was a reference to the number of WAGO "modules" and WAGO "size" in terminations.  I am not bothering to modify the docs this time, but a better naming convention such as wago_221-415_3x_mount.stl might work better. Wago_221-415 specifies the number of positions and the 3x lets you know home many modules the print holds.  If the overall quantity changes, then the normal voron quantity could be added.

Have you seen this thread and the linked Google sheet? 

It should be fairly simple to update for r2. I took it and massively reworked it for the Trident.

I did, but I just needed a simple migration sheet (actual paper... 🙂 ) for the shop where I do all my printing. I mark things off "mechanically" with a pen... 🙂

@Demosth, thanks for putting together that spreadsheet.  Very helpful.  I had a set of parts already printed for the original 2.4 but hadn't started assembling when r2 was released, so used your spreadshet to get a set of r2 updated parts printed out.

I've just assembled the Z drives.  I had both the original 2.4 and 2.4 r2 parts on hand, and inadvertently used the original Z drive main parts instead of the r2 parts.  Despite being listed as "functionally" different in that spreadsheet, I can't see any changes beyond some cosmetic ones.  The Z drive baseplate is indeed different to suit the guitar amp rubber feet, but it fits just fine to the original main and retainer parts.  Might be worth updating the spreadsheet (unless I've missed something critical) ?
