1. SKR3 and Relay V1.2 RepRapFirmware

   I am using SKR3 board with RepRapFirmware from official bigtreetech github. When connected via Relay V1.2, the power goes off after a few seconds. How do I set it to work correctly? The board.txt file shows the settings: atx.powerPin = E.4 atx.powerPinInverted = false in the file config.g at the very beginning of the file, the settings are indicated: M80 C "PSON"

2. Octopus V1.1 How do I implement the RESET pin function ?

   I have this Octopus driver board version 1.1 which is working just fine. I need to make use of the RESET pin which is part of a 5 pins connector just in between the Motor7 and BLT connectors. The connector has 5 pins which are marked RST PA10 PA9 GND 5V I need to know which pin the RST should be connected to such that it will perform a board RESET. Usually it is either the 5V or the GND. I just don't want to damage the board if I utilize the incorrect pin. The Question: What pin should the RST pin be connected to perform a board reset ? 5V or GND ?

4. Setting Temperature For Printing BIQU-B1

   I am new to 3d printing. Setup my new BLQU-B1 and would like to print the models that cam on the SD Card. I switched to a PLA+ filament. It needs at least a 205 degree nozzle temp. I don't know how to make that happen. No matter what I do it keeps changing to 180. Is that temp something built into the G-Code?

8. Setup SKR3 EZ with a Ender 3 Pro

   Hello, this is my last shot at this, because I'm truly exhausted by this printer. Short story... I have the printer for a year now, board broke, i bought the SKR3 EZ board, connected it and setup a RPI4 with MainsailOS. Issue: The printer is somehow setup but not properly, the axis length doesn't match, when I tell the printer to move +1 it moves like 1cm... the TMC2209 code block is uncommented as I haven't found any information how to set it up or if i need to set it up, just nothing. Any video I find about 2209 is mostly marlin while I use klipper, it's truly annoying because since a week the progress with this printer has stopped. Fell …

10. Delivery issues to the Netherlands

    Today, I tried ordering a product (the SKR mini E3 V3.0) from the official BigTreeTech website. Unfortunately when going through the checkout process, I get an error stating 'This order can’t be shipped to the address you entered. Review your address to ensure that all fields have been entered correctly and try again.'. I have never had this problem with any other website before and I am 100% sure I typed in the right address (I retyped it at least 10 times). Does anyone know what could possibly cause this issue and if there is a solution?

12. SD init fail

    Installed the SKR Mini E3 V3.0 to Ender 3 Pro and was previously using a micro SD to SD card extension cable adapter and I now get the "SD init fail" message. I tried using multiple adapters that I use on my other Ender 3 with same message. When I use the basic micro SD card it works properly so it's definitely not my micro SD card slot being damaged. What can cause this error and is there a fix? e

13. BTT s42c v1.1

    Hello all, just got the BTT s42c v1.1 kit off amazon. It came with no documentation. When I go to the BTT site I see a similar product which is version 1 I linked below. The kit below shows an aluminum alloy shell for the back of the stepper that the board mounts in. My kits are both missing those shells. Where can I get these shells and can I print them and where does the little magnet that comes in the kit go? I cant find anything online to help. I found a download that contains a pdf of so called instruction but ita VERY bleak and for the version 1. Not version 1.1. https://www.biqu.equipment/products/bigtreetech-s42c-v1-0-42-stepper-motor-closed-loop-driver-board…

14. SKR 2.0 Rev B in Ender 5, when EEPROM writing is enabled the system only boots to the marlin version screen and no status info page.

    Loaded a basic marlin 2.0.9.3 configuration: 1. Line 99 change the bd type to the "BOARD_BTT_SKR_V2_0_REV_B" 2. Line 110 change the serial port to "-1" 3. Line 864, 865, 866, 875, change to the "2208" stepper drivers I am using 4. Line 2475, enable "#define CR10_STOCKDISPLAY". I also changed to the correct environment: BIGTREE_SKR_2_F429, in platformio.ini. that works fine, I can move the steppers ok. But when I just change: Line 1834 #define EEPROM_SETTINGS, with that enabled I only get the marlin bootscreen showing marlin version. The system is an Ender 5 with the original LCD display. Configuration.h platformio.ini

22. Cooling fans don't work pt.2

    Hey, I ordered my printer off Amazon and installed everything correctly. The whole printer works fine, but the cooling fans on the side of the extruder don't work. If they're off or at 100% they don't spin, and I don't feel any air being blown onto my print. Is there some code I can input to reset the fans, or do I need a new extruder? I have a Biqu B1, and the motherboard is an SKR 2.0.

24. BIGTREETECH Octopus Pro V1.0 Voltage

    Hello! I recently bought myself a 3 in 1 out hotend and now I noticed that I need a motherboard with more stepper driver pins. I stumbled across the BIGTREETECH Octopus Pro V1.0 and when I checked the Voltage it says 15-28V input. The Problem is that my anycubic mega Pro is a 12V machine. Is there a way to make these two things work without buying a new Power supply? Or is there another board that Supports 3 Extruder Motors that works with 12V? -Lorenz
