Ender-3 V2-Marlin-2.0.1 - V1.3.1 - BLTouch.bin
Ender-3 V2-Marlin-2.0.1 - V1.3.1 - BLTouch - TMC2225.bin

Can you please explain the difference between those files? (Is there also a TMC2225 board, thought these were TMC2208 on the new 4.2.2 and 4.2.7 boards?)

PS: Will there be an official firmware, that is using the dedicated BLTouch connector on the new boards? Just saw in the video, that it is not used with this firmware.
So if I have wired my BLTouch like you described before it won't work?

Thanks in advance!

@admin Thanks for the info! So there won't be a Firmware for using the dedicated socket on the bord without unplugging the z-stop switch?

@Hronus Can you determine the exact spot where it gets stuck? Is it a blocked nozzle or does it get jammed in the ptfe tube? Perhaps your exrtruder is to rough to the filament and small pla flakes get scrubbed off. If they collect in the ptfe tube (esp. capricorn with smaller diameter then original) the filament might get jammed.
Or your ptfe tube is not sitting tight enough on the nozzle and a pocket of material forms which gets not extruded but stays in the hot zone. Perhaps the PLA then "crystallizes" in some way after beeing heated for hours and then eventually blocks your nozzle? (Perhaps PETG is more resistant to that...) Just speculating...

@Hronus Glad I could help!
Would imagine they manufacture the different colours of filament of the same basic batch of pla and just add the color when extruding it. So if the basic batch was spoiled...

PS: Haven't updated my Ender 3v2 to the latest version yet. (still waiting for the bltouch version... @admin ) so far no problems with pla...

@Hronus Just a few additional ideas regarding your problem, if the other material is not working...

• temperature of nozzle is dropping suddenly? (faulty heating element or circuit)
  Can you continue printing without cleaning the nozzle or removing the filament after a blockade, just by switching the printer off and on again? Can you measure the temperature of the nozzle when it blocks? (Perhaps try to push a piece of filament onto the nozzle and see if it melts when the blockage happens, if you can`t measure the temp. directly...)

• You could try to melt the blob at the end of the filament when you remove it after a blockade and see if there is anything hard in it or particles with a higher melting point then the rest of the filament. If there are impurities, they should be found there...

Have you already tried a different filament? Perhaps the cause is a impure or dirty filament?

Thanks for the support!

Any updates?
Thanks in advance!

@admin Can you please tell us, when there will be a 1.1.6 firmware with bltouch support for the ender 3v2? (using z-stop and bltouch, as there are now dedicated sockets for both on the board.) And please also provide the needed wiring diagram as soon as possible!

Thanks in advance!

Best regards
