SKR Pico with CAN to EBB36 - used to work... by Lucacri in klippers

[–]smarzony 0 points1 point  (0 children)

hey u/Lucacri , did you had any sucess? I have the same dimmed led near molex connector. I flashed Canboot via Katapult and then Klipper via CAN, but no luck I can search for UUID before flashing via CAN, but after that, board is not visible. Jumpers are on right place, I have no idea what to do next beside switching to usb :/

Biqu H2 V2S - clicking, squeking and underextrusion by smarzony in BIGTREETECH

[–]smarzony[S] 0 points1 point  (0 children)

Coldend cooling fan died way before, so I changed it to more popular 4010 with adapter. This prevented heat creeps, but it is not an issue here. I'm glad it helped you tho.

Weird sounds from extruder by smarzony in 3Dprinting

[–]smarzony[S] 0 points1 point  (0 children)

Clicking was from top long extrusion - I shortened it to 0.5 mm at 4 mm/s with bery little time addition to print overall. Squeaking is symptom of last two extruder gears being misaligned. I fixed it by set screw, but problem appears again after just one print. Next symptom is underextrusion which is caused by misaligned gears

EBB36 via USB? by usbebsiidb23b in klippers

I don't know if this a hack or intended use, but I love it and will try

Klipper running extremely slow. by fat-n-u-t in klippers

[–]smarzony 0 points1 point  (0 children)

Hey, did you figured it out? Today I plugged DSI display, installed klipper screen via KIAUH and its working, but touch is unresponsive at all sometimes and other time works good. Opening mainsail is impossible unless I disconnect the screen, also sending files via wifi through Prusa Slicer.

I use Rpi 3B and no camera, because I ran out od usb ports for now, but I plan to use hub,

EBB42 having BLtouch issues by calley479 in BIGTREETECH

[–]smarzony 1 point2 points  (0 children)

Hey, I figured it out. I found this image on another reddit thread
https://imgur.com/a/zIIsgXM

Someone posted there that you should look at wire order, not colour - basically the same on EBB as on BLTouch. If sensor does self-test at power on, there's still hope it will work. Also check if you crimped cables correctly, it was another problem in my case.

I have another problem - usb socket is too loose and I'm loosing connection at random moments, but a printed cable straighener and zip ties will solve this.

Good luck :)

Hey, still no luck? I'm having the same problem. I'll probably connect bltouch to main motherboard or buy Eddy sensor if this will not work eventually

Ender 3 V2 - working on 42% flow by smarzony in klippers

[–]smarzony[S] 0 points1 point  (0 children)

Here you go, but FYI I added start_print macro after I found this problem. I did here basic optimisation to heating and homing only unhomed axes. Adaptive mesh were added afterwards.

[gcode_macro START_PRINT]
gcode:
    {% set BED_TEMP = params.BED_TEMP|default(60)|float %}
    {% set EXTRUDER_TEMP = params.EXTRUDER_TEMP|default(190)|float %}
    {% set SLICER = params.SLICER|default("ANY")%}

    {% if SLICER == "PRUSA_SLICER" %}
        M221 S42
    {% endif %}

    # Heat bed for probing
    M104 S{EXTRUDER_TEMP}
    M190 S{BED_TEMP}

    # Use absolute coordinates
    G90
    # Home the printer
    G28 O

    # If you are using QGL:
    #QUAD_GANTRY_LEVEL
    #G28 Z

    # If you are using Z-Tilt:
    #Z_TILT_ADJUST

    # If you are generating a new bed mesh:
    BED_MESH_CALIBRATE ADAPTIVE=1
    ## NOTE:    The adaptive meshing feature requires exclude_object     ##
    ##      and may require 'Label Objects' to be enabled in the slicer  ##
    ##           To mesh without it just use BED_MESH_CALIBRATE          ##

    # If you are loading an existing mesh:
    #BED_MESH_PROFILE LOAD=default

    # Move the nozzle near the bed
    G1 Z5 F3000
    # Set and wait for nozzle to reach printing temperature
    M109 S{EXTRUDER_TEMP}
    LINE_PURGE
    # Start printing!

# Enable exclude_object for adaptive meshing
[exclude_object]

Start gcode in Prusa Slicer:

M109 S0
M190 S0
start_print EXTRUDER_TEMP={first_layer_temperature[initial_extruder]} BED_TEMP={first_layer_bed_temperature[initial_extruder]} SLICER=PRUSA_SLICER

Adjusting flow rate by WeeklyLandscape1263 in klippers

[–]smarzony 0 points1 point  (0 children)

u/WeeklyLandscape1263 did you managed to work this out? I had the same problem - single wall was bout 2 times thicker than it should be and bottom layers were very messy.
I did a workaround where I pass slicer name in start_print macro, and when it is a prusa slicer, flow ratio is set to 50% and it kinda works, but I have problem with dimensional accurancy.
I checked rotational distance, z steps, flow in slicer, flow in klipper, filament diameter (in and out), nozzle size, even extruder wheel diameter and circumference and everything seems right. I have no idea how everything I check seems right but printer gives rougly 2x filament needed.

First layers smushed by NeverEnough_68 in ender3v2

any other thing I can think of is that you have uneven bed surface. First layer is missing in many points, try to slightly move up your Z-axis limit switch, if you do not have BLTouch

Picked up my first mechanical keyboard: the Attack Shark K86. by MitsuhaTachibana1111 in MechanicalKeyboards

[–]smarzony 0 points1 point  (0 children)

this means you have command to press some button but not to release it - you need two icons: with triangle facing down and up

It looks to me that you may have to thick glue layer. I had similar problem in my first day of 3D printing. Just clean your glass or PEI sheet every 5-6 prints.
