I got the CR-10 S5 and bought the BL touch autoleveling kit.
My printer appears to have the 2.1 board which does not have an easy way to attach the BL touch.
So I gave up on installing it onto this board. Instead I bought the 427 board with ender 3 firmware.
I attached most of the wires but I am not sure where to attach:
the fans (got 2 case fans and the extruder fan, but there are only two sockets)
the filament sensor (this is unreliable anyway)
Which firmware do you recommend?
I already built Marlin 2.1 but before burning I would like to fetch the original firmware. Can I do that with stm32flash? how? I cannot get a connection.
As far as I am aware the 4.2.7 board is not officially supported by the CR-10 printers. Partly due to lack of connectors on board for some components but also you would usually require a completely different screen to work with the 4.2.7 board.
Yes the first file in the list documents which versions should be used with different versions of the board.
To flash the firmware you would usually place the bin file onto an SD card formatted as FAT32 with 4096 allocation units. Insert the SD into the printer and power on.
You’re welcome! Yep you will likely find that the Ender logo is baked in to the chip on board. Glad to hear you were able to get the firmware flashed
The new CR10 427 firmware worked somehow, but had wrong dimensions (smaller than 500x500) and I did not find out how to calibrate auto leveling. (ie height difference between probe and hotend)
I connected both Hotend fans to the controlled fan sockets. But they can only be controlled together. Should I connect one of these to permanent power?
I installed self-built marlin 2.2.x. initially there was a lot wrong about axis’ and end-stops, but now most of the hardware seems to work.
The ender logo isn’t hard wired. I expected I had installed the Creality logo, but it shows marlin logo.
I just cannot figure out how to use autoleveling UBL. It just does nothing. (less than the stock firmware)
Had to set it to:
//#define Z_MIN_PROBE_USES_Z_MIN_ENDSTOP_PIN #define USE_PROBE_FOR_Z_HOMING
//#define Z_MIN_PROBE_PIN -1
Now the extruder doesn’t extrude. 8)
negative values are for retracting, positive for extruding?
It seems to run in a virtual wall before anything leaves the extruder. the motor just doesn’t continue running…
Thanks. It works now.
I will publish my config in the Marlin-Config-Repo on config/examples/Creality/CR-10 S5/CrealityV427-BLTouch/
Somehow the command to test the bed leveling does not work. As shown in the guide I tried
G26 C P5.0 F3.0
But it does not extrude any material. This is why I tried to figure out what is wrong with the extruder. Maybe Cura gives higher flow speed than what the printer believes is correct. So Cura works but the above command doesn’t.
