Trying to create a config file from scratch

Basic Information:

Printer Model: Lotmaxx Shark V2
MCU / Printerboard: STM32F407
Host / SBC
klippy.log

Describe your issue:

As the title implies, I have recently acquired a Lotmaxx Shark V2. I’m new to Klipper as I’ve just converted my CR10 Smart to Klipper. I’ve seen online, many people commenting about not having the pinout for the Shark, and “China” will not provide it. In fact, their firmware is very hush hush as the M503 command returns very basic info, like what axis and limit switches are inverted. I got bored at work, and took the board and my meter. I now have the pinout, all the way to the laser. However, I’m not very knowledgeable with Klipper to generate my own config file. If I provide the pinout, could someone help me generate a config file and I will test it on my printer. If successful, it can be uploaded to klipper to add to their database.

Thanks in advance.

Basically it is not that hard. Take the config of something vaguely similar, e.g. klipper/config/generic-mks-rumba32-v1.0.cfg at master · Klipper3d/klipper · GitHub, and replace the pin definitions with yours.

Thanks. I’ll try it. I noticed it has an extruder setting, then below it are extruder 1 and 2, both commented out. Do I do the same, or “define” both extruders and leave them uncommented? (not sure what the correct term is, but don’t put a hash tag in front of the line).

Well, if you have more than one extruder then you might want to use it. Your goal is to reflect your physical hardware with the appropriate setting blocks.

Any chance you could share the pinout and your journey? I am considering it on my Shark v2, It is fully calibrated and printing beautifully but slowly.

Give me a couple of days. I’ll dig everything out. I sold the printer, so i didnt pursue any further.

Below is the pinout I have for the Shark. I do not know what bootloader to load, but the chip is correct. If you scroll down, I made a note where I stopped. I don’t know if the bottom part will work or not. Again, I haven’t tested this as I have sold my shark. Please keep me posted on your success (I’d like to know if I did something right or not…lol). Thanks.

This file contains common pin mappings for Lotmaxx Shark V2. To use

this config, the firmware should be compiled for the STMicroelectronics STM32,

Processor model STM32F407.

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

@Hammer3091 :

Either upload your code as a file:

Upload

Or at least use the Preformatted Text feature of the forum editor for your code:

Format

The way you did makes it useless.

I wouldn’t say its useless. You can always type it in by hand into your printer config file like I’ve been doing. However, in the interest of speeding things along, I don’t have the options you posted. I am very new to 95% of this (except the internet. I predate the internet), so if you could tell me where exactly those option are, I’d be happy to help make things easier for you.

It’s useless because There are missing spaces and other characters are used to re-format the text. That way.

It should look like this:

# This file contains common pin mappings for Lotmaxx Shark V2.  To use
# this config, the firmware should be compiled for the STMicroelectronics STM32,
# Processor model STM32F407.

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

I don’t have those options on a computer. I only have those options if i private message someone. Where are those options on a computer?
