Turns out reading is good
I just figured out that all Big Tree Tech main boards are open source. Turns out reading and trying to find answers on internet is kinda nice.

Turns out making a 3D printer main board is not that easy. I must say I went into it with too much "not thinking" and too much enthusiasm. However, I got some knowledge, and a new idea that can be realized faster than the whole main board.
STM32H723ZGTx not even funny
There it is in KiCad. I can't understand why it has so much VDD pins. I guess i can just copy the capacitors on those from someone else. 12 * 100nF caps. Guess one for each damn pin. Just will take too much space on the board. What follows
STM32H7 pin connections for 3D printer main board
In order for Marlin firmware to work properly on my imaginary main board I'm building. Turns out there is a file in a Marlin GitHub repository that has pre set pins for certain popular main boards that use H7 as their brain. One of those is a BTT
What does the simplest 3D printer main board need?
Well the task of making a main board is incredibly complicated, that's why it needs to be as simplified as much as possible. The schematic of Ender 3 motherboard is a good reference I feel. Because they wanted to cut costs everywhere they could. That includes a main
Let's say I want to make a 3D printer main board
LMR51450SDRRR - Voltage regulator [1] TPS2116DRLR - Power source selector [2] TXS0108ERGYR - Logic voltage translator [3] LM61495RPHR - Voltage regulator [4] LP5912-3.3DRVR - Voltage regulator [5] Those are all some kind of voltage regulators I found in SmartPrintCoreH7x [6] open source main board. And those are not all. It seems to me
Turns out stepper motors are a bit more complicated
Found this nice short manual about stepper motors [1] by Oriental motor [2], which is a US based company that manufactures stepper motors. Dude, I'm not cut out of this. I'm able to understand it a little, but then it starts to build hard concepts on
Connecting Arduino with Simulink a bit hard
Trying to connect a distance sensor that works over I2C with Arduino and god damn Simulink is confusing. There is no library for sensor that I'm trying to connect (vl6180 sensor), and reading data over I2C is not the way to go. Probably need to buy the right
How do they sell those boards?
It's my dream one day to start manufacturing and selling electronics. However, it's not an easy road ahead. Seems like EU laws are a big obstacle. I'm not saying those laws are bad. They probably protect everyone, however it is hard to start selling
Adaptive steps on stepper motor
I got this bright idea to try making stepper motor go faster. So I can make my 3D printer go faster. However, the experiment that I did shows that it is not a good idea. This is not a professional experiment in any way, it's more for my
What's up with 3D printer motherboards
Well, 3D printers got my interest, and as an electrical engineer, only thing that I have some pre knowledge for is the electronics part. And that's pretty much only motherboard and power supply, and maybe motors. But I feel like 3D printers are more of a mechanical engineering
