Sanity Check** I need HELP!

cabinfourus · June 7, 2022, 4:53pm

I am very new to Klipper and really want to give it a try. I just finished building a Cartesian style printer with an Octopus Pro board and want to run the Klipper firmware on it. I have always been hardcore Marlin when it comes to firmware but only because I understand it well. I have been able to flash the Octopus Pro with the Klipper firmware without issue. I am using Mainsail with Klipper and have everything installed onto my Pi. I can access the Pi through SSH and Mainsail is working fine.
My problem is the lack of confidence in my own work. I’d love for someone to help me Sanity check my printer.cfg file. I used the example configuration from Klipper but I have a lot of extras I need help with.

I have an MKS PWC power module connected to the Octopus Pro in the power detect connector. I also have a BigTreeTech 24 volt UPS module. Would I need to define the pins for these two?
I am also having trouble with setting up the Z tilt. I have been over the Klipper information 20 times and still don’t get it. Do I need to define the voltage in Klipper?
I will include my printer.cfg info below if anyone here can take a look and see if they spot anything I may have missed or got wrong.

My setup:
Cartesian style printer
Octopus Pro main board
24 volt power supply
Nema 17 motors
TMC2209 (BTT) drivers in UART mode
Dual Z drivers
300 by 300 mm heated bed
MKS PWC power module
24 volt UPS (BTT)
TFT35 v3.0 (BTT)
Dragon hot end
dual part cooling fans
separate cooling fan on the TMC drivers

Firmware
Klipper with Mainsail

This file contains common pin mappings for the BigTreeTech Octopus.

To use this config, the firmware should be compiled for the

STM32F446 with a “32KiB bootloader” and a “12MHz crystal” clock reference.

See docs/Config_Reference.md for a description of parameters.

The Octopus only has 4 heater outputs which leaves an extra stepper

This can be used for a second Z stepper, dual_carriage, extruder co-stepper,

or other accesory such as an MMU

#restart_method: command

setup for PA9, PA10 USART1_tx / rx directly connected to the RPI GPIO TX / RX pins

These are the pins the OctoPus uses for its built in RPI 40 pin connector

only connect GND, TX, RX - supply 5v power to the RPI separately

do not cross over TX/RX - it is done internally on the OctoPus PCB.

Use “sudo raspi-config” to disable the serial terminal - but enable the serial port.

When running “make menuconfig” you must un-select the USB Serial check box
