No mechanical modification on the printer except fitting of the screw domes for the new motherboard.

Electronic

Motherboard

BIGTREETECH OCTOPUS Pro V1.0.1

CPU

STM32F429ZG

Stepper driver

The TMC2209 has only Step/Dir mode and UART, NO SPI.
Therefor the pins below the StepDriver are configured in UART mode:

oIoo
oIoo
oooo

The output voltage of the StepDriver should be the same as the supply voltage.
Since the TCM2209 is not supporting other output voltages, the jumper will use the 24V of the board:

o==

The TMC2209 supports StallGuard, which is connected to the diag pin.
The StallGuard is overwriting the endstops, therefor they will not be used:

oooooooo
oooooooo

Fans

The Fans are all 24V therefor the jumpers will bridge the last pins:

oo  5V
oo  12V
==  24V

PT100 DIP Switch

The Tenlog 3D-Pro is using PT100 temperature sensors.
Therefor all dip switches will be set to ON (which was default on my board).

Power supply

To avoid powering the board via USB,
the Power jumper in the center of the board needs to me removed.
For installation and debugging I will keep it connected for now,
But in production I need to remove the jumper!

BLTouch

The BLTouch will be connected the flowing way:

ooooo

Fans

Seems like all fans can be connected directly.

Housing Fans

Use the 2 extra fan plugs (Fan4 & Fan5) in Controller Fan Mode.
This disables the fans if there is no driver or MOSFETs in use.

Buffers

Increased all buffers to the max to reduce lags in WiFi data transfer.
Enabled XON/XOFF control characters.

Calibration

PID Auto Tune

Bed

I run a PID Auto Tune with 9 cycles on the bed:

M303 C9 S60 D1 U1 E-1

With the new values the configuration is:

#define DEFAULT_bedKp 136.38
#define DEFAULT_bedKi 25.83
#define DEFAULT_bedKd 480.06

Hotends

I run a PID Auto Tune with 9 cycles on both hotends:

M303 C9 S210 D1 U1 E0
M303 C9 S210 D1 U1 E1

With the new values the configuration is:

#define DEFAULT_Kp_LIST { 26.65, 24.61 }
#define DEFAULT_Ki_LIST {  3.00,  2.65 }
#define DEFAULT_Kd_LIST { 59.16, 57.10 }

$I_{RMS}=\frac{325\textup{mV}}{R_{sense}+20\textup{m}\Omega}\cdot\frac{1}{\sqrt{2}}\cdot\frac{V_{ref}}{2.5\textup{V}}$

UBL

  1. Level bed manually on all 4 corners
  2. Run 
    G0 Z10
G30 X154 Y154
  3. Read out result and calculate
    $Z_{M851}=Z_{M851}-Z_{Probe}$
  4. Write probe offset with 
    M851 Z#.##
  5. Run UBL 
    M420 S0   ; disable bed leveling
G28       ; home all axes
M155 S30  ; reduce temperature reporting rate to reduce output pollution
M190 S60  ; wait for the bed to get up to temperature
G4 S60    ; wait another 1 min for the bed to reach temperature
G29 P0    ; clear mesh
G29 P1    ; automatically populate mesh with all reachable points
G29 P3    ; infer the rest of the mesh values
G29 P3    ; infer the rest of the mesh values again
M420 S1 V ; enabled leveling and report the new mesh
M500      ; save the new mesh to EEPROM
M155 S3   ; reset temperature reporting
M140 S0   ; cooling down the bed
  6. Correct whole mesh with 
    G29 P6 C#.##
