Hi All, I thought I could share my current configuration since I've made a few modifications compared to the factory setup. Some of these modifications were directly taken from what has been shared on this forum. Thanks to all contributors! Feel free to comment and post suggestions :-) I'm likely going to try Klipper. 1 Initial configuration DSH H-H Mic-6 hot bed Enclosure Raspberry Pi 4 with 8GB RAM Pre-assembled 2 Upgrades/Modifications 2.1 General Synchronization belt for Z steppers (https://www.forum.makertech3d.com/forum/proforge-3-3d-printing/upgrades). Changed the two heat-breaks for bi-metal (copper/titan) heat-breaks to prevent heat-creep issue occurring on long PLA prints. Added 15mm of a 6mm PE tube inside the cable housing going to the print head to add more rigidity and prevent all the cables to hit the heated bed during prints. 2.2 Silencing the printer Noctua NF-A4x20 FLX + NA-RC10 + for electronic case cooling. Noctua NF-A9-14 PWM + NA-RC10 + custom case for the power supply. E3D NEMA 17 stepper motors 0.9°, 1.68A as X/Y motors replacement. Depite StealthChop being activated, the original stepper motors were super loud. Addition of dampers for the X/Y stepper motors. Replacement of the 50x15 blower for part cooling with a 50x20 blower (Mechatronics Fan Group, B5020L24B-BSR). Custom fan shroud to fit the new fan. Replacement of the two 30mm heat-sink fans with 2x Noctua NF-A4x10 FLX using a custom mount (https://www.forum.makertech3d.com/forum/proforge-3-general-discussion/dsh-heatsink-fan-upgrade). 2.3 Marlin Setup Marlin to allow firmware update with OctoPrint. https://github.com/OctoPrint/OctoPrint-FirmwareUpdater/blob/master/doc/lpc176x.md platformio.ini [platformio] src_dir = Marlin boards_dir = buildroot/share/PlatformIO/boards default_envs = BIGTREE_SKR_2_USB // Allowing connection from Pi to SKR_2 include_dir = Marlin Configuration_adv.h #define FAST_PWM_FAN // Increase the fan PWM frequency. Removes the PWM noise but increases heating in the FET/Arduino #if ENABLED(FAST_PWM_FAN) #define FAST_PWM_FAN_FREQUENCY 329U // Silencing the blower fan when not at 100 % Configuration.h #define FILAMENT_RUNOUT_SENSOR #if ENABLED(FILAMENT_RUNOUT_SENSOR) #define FIL_RUNOUT_ENABLED_DEFAULT true // Enable the sensor on startup. Override with M412 followed by M500. #define NUM_RUNOUT_SENSORS 2 // Number of sensors, up to one per extruder. Define a FIL_RUNOUT#_PIN for each. #define FIL_RUNOUT_STATE HIGH // Workaround to use the M412 S1 for filament runout detection 3 Current issues Frame is not sturdy and not at 90° angle => enclosure do not close properly Fan of enclosure do not work or is not reacting to M106 P2.

Hi there, I'm trying to setup Cura+Octoprint for the Proforge3. So far I could setup a Pi with Octoprint following the build manual. Since I'm using linux, I also had to build a Cura AppImage following the method described by @Dries Douterloigne on this post: https://www.forum.makertech3d.com/forum/proofrge-3-general-discussion/cura-for-linux. On Cura, I'm able to install the Octoprint plugin and have it successfully connected to Octoprint. So far so good... except that each time I send a .gcode file to the printer via Octoprint, I get a FilamentRunout T0 error (and obviously my filament is correctly loaded). Afterwards, sometimes I can resume the print, sometime the printer get stuck in an infinite error loop and I have to power it off. Since I'm new to Cura and Octoprint, I was wondering if I missed some configuration part or something else. For example, do I have keep a SD card in the SKR 2 or can it work without it? Note that starting a print from the SD card reader of the touch screen works just fine. Here the output of the Octoprint terminal where you can see the error happening. Thanks in advance for your support.
