Getting orange pi 3 lts + klipper working with anycubic kobra 2 neo

I couldn’t scan it, but here are hi-res photos of both sides

guys i still cannot flash it, i think that’s an sd card fault. What sd card have you been using for flashing and what filename? Was there any other files on a sd card except the .bin file?

It doesn’t matter if there are other files on the sd card. Filename should be firmware.bin
I used some old 2GB sd card formatted with fat16 as the one that was included with the printer died

Thank you for the great work. I still get an error:

uncomment “position_endstop: 0” in stepper_z section of printer.cfg

I thought so much. Any reason why it was commented in the first place?

When you save z offset in mainsail it automatically comments it out and puts z offset as new z endpoint position at the end of the config. I just didn’t notice this behavior at the time of posting that config file.

Anyways. It is working perfectly. Thank you very much. you are a genius.

By the way, the flashing proccess took less than 3 seconds.

Now I have a problem with unknown commands when starting a print.

They are suppose to be errors related to the acceleration.

Is there a way to deactivate the accelaration via AnycubicSlicer? or to go around this acceleration thing?

For that fix check on the printer.cfg file. there is a link to a plugin you need to install, that will auto calibrate the z axis

No trigger on probe after full movement

same problem here

change position_min to a smaller value

I have a problem with the M109 comede because after changing to the clipper, the printer warms up for about 6 minutes, I did pid calibration twice but it didn’t help.

fat16 or fat32?

if i remember correctly the printer uses a fat32

it doesn’t work neither i use a fat32 or fat16 filesystem. Possibly an SD card fault.

Here the same. The print starts after 6 minutes warmup, even when the temperatures were long as per set point

How can I set up the startup code in the slicer so that the printer does a purgeline?
When I work with the original firmware, it works like this

G90 ; use absolute coordinates
M83 ; extruder relative mode
M140 S[first_layer_bed_temperature] ; set bed temp
M190 S[first_layer_bed_temperature] ; wait for bed temp
M104 S[first_layer_temperature] ; set extruder temp
M109 S[first_layer_temperature] ; wait for extruder temp
G28                                        ; move X/Y/Z to min endstops
G1 Z0.28                                   ; lift nozzle a bit 
G92 E0 
G1 Y3 F1800                                    ; zero the extruded length 
G1 X60  E25 F500                       ; Extrude 25mm of filament in a 5cm line. 
G92 E0                                     ; zero the extruded length again 
G1 E-2 F500                                ; Retract a little 
G1 X70 F4000                              ; Quickly wipe away from the filament line
M117

With Klipper I always get this error:

Move exceeds maximum extrusion (15.033mm^2 vs 1.000mm^2)
See the ‘max_extrude_cross_section’ config option for details
