I need some help, newbie in trouble

Basic Information:

Printer Model: Custom chasis ender 3
MCU / Printerboard: SKR3 mini V3
Host / SBC X86 mini pc atom
klippy.log
klippy.zip (1.1 MB)

Fill out above information and in all cases attach your klippy.log file (use zip to compress it, if too big). Pasting your printer.cfg is not needed
Be sure to check our “Knowledge Base” Category first. Most relevant items, e.g. error messages, are covered there

Describe your issue:

Well I will try to explain my madness, I have mounted a monster that I do not know how to master. It is or was a normal ender 3 that has mutated into a thing.

It has linear guides on all the axes.

double z axis with nema 42-40 motors (I couldn’t choose, it was the offer).

creality spriter pro extruder with ceramic hotend

220v hot bed with relay

Much red

SKR 3 mini V3 board

7” TFT screen

Mini pc for klipper

Before taking out the screwdriver it was a simple ender 3 that I bought in a second hand for 60€ and that worked well and helped me to deliver some 3d presents for christmas. Then it was time to bring the red monster to life and that’s where my little problems started:

  • The y-axis:

totally off center, I have respected the position more or less of the endstop but the bed moves to the endstop and when I ask it to move to the start it does not do it, it tells me out of range.

The X axis:

remains in the air, I know that by measurements the shaft offset has been modified.
as the bed is not centered with the axis and the home position is not correct, add that I have installed an original creality bltoucht and it indicates No trigger on probe after full movement after the probe_calibrate command.

I need help to understand how to measure and solve this.

I would like to upload the log but it is 6 megas and paste bin does not support it.

and this:

MCU ‘mcu’ shutdown: Timer too close
This often indicates the host computer is overloaded. Check
for other processes consuming excessive CPU time, high swap
usage, disk errors, overheating, unstable voltage, or
similar system problems on the host computer.
Once the underlying issue is corrected, use the
“FIRMWARE_RESTART” command to reset the firmware, reload the
config, and restart the host software.
Printer is shutdown

this is yet another problem, when trying to heat the hotend or hot bed it restarts.

I have checked the wiring several times, finding something wrong and I have repaired it, I have searched many configurations on the internet and the little I am learning and understanding I apply it.

Hello @ctrquko !

Honestly? Over 3300 lines of config?
Did you wrote them all yourself?
Are you sure thy do not influence each other?

Have you tried with a minimal system?

3

is the klipper log not my config this is my config file:
printer.cfg-20250118-200212.zip (1.5 KB)

4

In the klippy.log, the printer.cfg appears with all lines that are used.

5

I am new in this field, not so much in other areas, the printer cfg is adjusted to the parts that the machine has, all this investigating the options and trying one by one, I understand that they do some of the instructions included in the file but not all. In this case reading from the fluid editor it has 161 lines, and in the log it will appear I guess since I have the printer.

I need help to understand what I don’t understand, how to adjust the current printer dimensions.

6

These lines in your config are included and make things huge.

[include macros.cfg]
[include fluidd.cfg]

In particular the first one.

7

if I delete the fluid.cfg I have this error
[virtual_sdcard] is not found in the printer configuration.
[pause_resume] is not in the printer configuration.
The CANCEL_PRINT macro is not in the printer configuration.

8

fluidd.cfg has to stay. Else Fluidd will not work.

You may comment out the line

[include macros.cfg]
9

I have done it, could you tell me how to fix the position of the Y axis, actually it reaches the endstop but I can’t get it to make the full travel of the guide until the end of the -Y.

We don’t know the dimension of your custom printer.

So we can’t compare it to the config settings.

In what way “off center”?

To the OOR error:

Move out of range: 0.000 236.000 0.000 [0.000]

This more than it is set in the config:

[stepper_y]
step_pin = PB10
dir_pin = !PB2
enable_pin = !PB11
microsteps = 16
rotation_distance = 40
endstop_pin = ^PC1
position_endstop = 0
position_max = 235
homing_speed = 50

But what did you try to achieve with these?

...
[stepper_y]
step_pin = PB10
dir_pin = !PB2
enable_pin = !PB11
microsteps = 16
rotation_distance = 40
endstop_pin = ^PC1
position_endstop = 45
position_max = 235
homing_speed = 50
...
[stepper_y]
step_pin = PB10
dir_pin = !PB2
enable_pin = !PB11
microsteps = 16
rotation_distance = 40
endstop_pin = ^PC1
position_endstop = -45
position_max = 235
homing_speed = 50
...
[stepper_y]
step_pin = PB10
dir_pin = !PB2
enable_pin = !PB11
microsteps = 16
rotation_distance = 40
endstop_pin = ^PC1
position_endstop = 0
position_max = 279
homing_speed = 50

?

BTW: How do you know that all the macros in macro.cfg are needed?

11

in reality it is still an ender 3 in hot bed size, 235x235, and no the macros cfg it’s a copy paste I’m still researching what each one does

12

Have you checked the slicer settings?

It’s not a good advice to C&P everything you come across.
Not everything is needed.
Some macros do the same.
And sooner or later you lose overview of your system.
Also it’s advised only to use macros you understand what they do and how they are doing it.
