  • Support for Ender 3 S1 with the STM32F401RCT6 SoC

    Support for Ender 3 S1 with the STM32F401RCT6 SoC

    New Release candidate version with the changes from the APRIL2022 release, only for Ender3S1 with the STM32F401RCT6 chip:

    Ender3S1-STM32F4-20220515.zip

    The issue https://github.com/mriscoc/Ender3V2S1/issues/125 has been fixed.

    @houseofbugs has discover that the firmware must be inside the STM32F4_UPDATE folder of the memory card for a correct flash procedure in some S1 F4 printers.

    This is a private build for testing the compatibility of the firmware with the Ender3S1 with the F4 SoC, please use it with caution.

  • Changed settings are not stored to EEPROM when saved (STM32F401)

    Changed settings are not stored to EEPROM when saved (STM32F401)

    Describe the bug Changed settings are not stored to EEPROM when saved.

    To Reproduce Steps to reproduce the behavior:

    1. Change any setting
    2. Select "Store Settings" or send gcode M500 through terminal.
    3. Power cycle printer
    4. All settings have reverted to firmware defaults.

    Expected behavior Changed settings should survive a power cycle after being stored.

    Version (please complete the following information): Experimental build 2.1.0.1 15Apr2022 (STM32F401).

  • Ender3 S1 Mesh Values Wildly Deviate as Mesh Size Changes

    Ender3 S1 Mesh Values Wildly Deviate as Mesh Size Changes

    Describe the bug Depending on the mesh size chosen, the values at different points will be wildly different than the same or near the same points in higher or lower point meshes. Not only that, but after changing the Z-offset after an auto home (or z-home) OR doing it right after the points have been measured and mesh saved; I will move to the front part of the bed where the values deviate most and the paper I use to change z-offset is almost always heavily gripped between the nozzle and bed when it was fine at the center.

    To Reproduce Steps to reproduce the behavior:

    1. On a Stock Ender 3 S1 running the latest S1 specific firmware, preheat the bed to usual temps.
    2. Advanced -> Mesh size -> try different sizes after repeat, starting with 4x4 (or 3x3).
    3. Take photos of the meshes to check deviation over points under the same heating cycle.
    4. See possible high deviation with error on mesh values at certain points (test with paper and moving x and y to different points with z at 0 and A4 paper underneath, both just after mesh and then homing).

    Expected behavior An auto-level z-compensation mesh with +- 0.002mm (tested with m48) values to account for bed warping on a levelled bed.

    Screenshots Please see below all the different mesh creations under the same thermal profile on a CR touch on the Ender 3 S1:

    image image image image image

    NOTE: The screenshots with the button over continue do not mean I chose continue, I saved each of these and did the aforementioned tests.

    Version (please complete the following information): Ender3 V2/S1 Professional Firmware 20220302 - maintenance release II - March 3rd, 2022 (Ender3 S1 version)

    Additional context Any help or insight is appreciated, other than this issue I really like this firmware! I have the Z feed rate in the probe settings set to 960 if that's any help, as per your mesh guide mentioning the CR-touch support. Could this be part of the problem?

  • mesh leveling doesn't work well

    mesh leveling doesn't work well

    The mesh leveling curiously don’t work for me. I got 4 models of the Ender 3 S1, two with the F103 and two with the F401 board. On every single printer the same problem: It seems like it’s working (z-axis moves), but not the shape of the bed. When I turn the ABL off, manually perfect levelt, it works way better. On the following Picture you can see the results in comparison, the lower sheet is with ABL turned on. Hopefully someone can help me. BTW I also got the problem on stock firmware.

  • Ender 3 V2 Neo support

    Ender 3 V2 Neo support

    I'm wondering if the new V2 refresh (Ender 3 V2 Neo) can be added to this project. It comes with auto leveling and some slightly upgraded internal bits too and a new screen but I think the mainboard is the same as the standard V2. It also runs a version of Marlin Firmware.

  • Thermal analysis and determination of the thermistor of the Sprite extruder Pro

    Thermal analysis and determination of the thermistor of the Sprite extruder Pro

    I'm on a e2s1 pro with a e3v2 knob-display running your firmware and I used the custom Gcode C104 U1 T315 to unlock my full temp range. I couldn't enter the gcode into pronterface, it claimed it didn't recognise the syntax. So I created a gcode file containing:

    ;set new Temp
    C104 U1 T315
    
    ;save settings
    M500
    
    ; display for confirmation
    M117 Temp setting done!
    

    Which initially worked, i confirmed manually in the set temps menu and I could select temps up to the entered range. However, whenever the Hotend actually reaches 270°C or above the printer enters panic mode and wants to be shut down immediately. Apparently, there's a different monitoring routine somewhere, that needs to be updated with the new maximum hotend temp so the safety protocol isn't falsely triggered.

    Anyways thanks a LOT for your work on tis firmware!

  • Z at right edge out of mesh border is being overcompensated for UBL with a 9x9 mesh

    Z at right edge out of mesh border is being overcompensated for UBL with a 9x9 mesh

    I've got a 9x9 mesh, HS probing disabled, multi probing disabled (one probe per meshpoint). I'm running this precompiled version on an E3 S1 pro, F1 Board. My probe has been relocated to be in line with nozzle on y-axis. On a sidenote, the physical machine limits are/were incorrect (too small) and I had to set correct values, mesh inset is close to maximum size from what the probe can reach, which is bigger than on stock since I relocated the probe. (x min=10,0; x max=216,0; y min 10,0; y max 218,0)

    The unedited mesh is too far away on the right back corner so I tried the "tilt mesh" function which resulted in this weird jump over a nonexistant bump. I included a video because it is so ridiculous. It didn't do it on the untilted mesh. The gcode file certainly has no Z-movements there. I've had this issue before, but the jump wasn't as pronounced as the one I got filmed here. I think back then, I didn't tilt the mesh, but used the "edit mesh" function, but I wasn't out to document a bug so steps might have been different. I've only ever seen this on the right edge, but maybe I didn't get close enough to the other edges. I had to rename the gcode file to csv, so it would upload.

    Here's the video

    this is my current mesh (after the tilt) meshPic

    This is the testfile it happened with. (rename to *.gcode) CE3_SquareTest.gcode.csv

  • Bed leveling off

    Bed leveling off

    About the printer

    Version: Ender3v2-422-BLTouch-20220202.bin Settings: Imgur album Mods:

    Example drawing

    The red line illustrates where the probe and hotend starts. The line is aprox 8.5mm off. It might be related to chainging the mounting plate. That does not explain why it levels all the way in the front of the bed.

    Version (please complete the following information): Latest config from special version (self compiled): Recv: FIRMWARE_NAME:Marlin 2.1.0.1 MRiscoC Ender3V2-SKRME3V3-BLTUBL-T13-LA, based on bugfix-2.1.x (Aug 29 2022 09:45:14) SOURCE_CODE_URL:github.com/mriscoc/Ender3V2S1 PROTOCOL_VERSION:1.0 MACHINE_TYPE:Ender3V2-SKRME3V3-BLTUBL-T13-LA EXTRUDER_COUNT:1 UUID:cede2a2f-41a2-4748-9b12-c55c62f367ff

    Additional context Just switched from Creality 4.2.2 to SKR Mini E3 V3 - no other changes done, same cable used. Octoprint connects normally, but serial connection fails when print is started (after heating finished). Printing from SD Card works fine.

    See the video, I'm using the version with BLTOUCH.

  • G34 Option in menu

    G34 Option in menu

    Some UI like Marlin have an option to run G34 in the menu. In Marlin I believe it's under Motion > Z Auto Align It would be great if it could be added to Professional Firmware for those of us with dual z-axis + dual steppers.
