The sixth upgrade will theoretically be the one you are all waiting for, a new motherboard with other stepper motor drivers ( drivers ).

Here again it is more complicated. The new album should give you something more than the original one.
Honestly, everybody will offer you today.

New silent album from Creality SKR Mini E3 SKR Mini E3 DIP SKR 1.3 SKR 1.4 / Turbo
around 1400 CZK around 650 CZK around 650 CZK about 400 CZK about 500 CZK

Even this ordinary motherboard offers something extra. It will offer silent drivers TMC2208 that really significantly silences the operation of your 3D printer. Even if it is a direct replacement where you exchange a piece for a piece, the price is really high in price / performance comparison.

Since this is a direct replacement of the original board, there is no need to change anything on the printer. Just replace the board with the board.

A better choice is this board, which is again a direct replacement of the original board and is available in two versions. Both versions of the motherboard offer a more powerful 32 bit microcontroller for faster and quieter printer operation.
It includes more firmware space and the ability to connect more components to your printer.
These include a BLTouch calibration sensor, a touch-sensitive color display, a power failure sensor, a filament end sensor, and the ability to connect RGB Led lighting so your printer can play in all colors. The board contains a fuse and a better version of silent drivers. Specifically, the TMC2209 is connected in UART mode, allowing you to change their behavior while the printer is running.

The SKR Mini E3 DIP version is almost the same as the SKR Mini E3 , but does not include integrated drivers, so there is the option to choose the drivers at your discretion.

It is still a direct replacement of the original board, so there is no need to change anything on the printer. Just replace the board with the board.

As the best option I would choose a verified SKR 1.3 . It offers an even more powerful microcontroller than the previous board, but has almost all the same functions. In addition, you will get more free pins, the possibility of connecting a second extruder and also support interchangeable drivers.

This board already needs to modify the electronics box and is not a direct replacement!

SKR 1.4 and SKR 1.4 Turbo are probably the best options at the moment.
What makes this album interesting?
It has more free pins to connect components supporting different protocols, dual Z support, the ability to attach a special step-down (converter to a lower voltage) for fans and support for multiple fans.
In addition, the SKR 1.4 Turbo has an even more powerful processor than its predecessors.

Again it is not a direct replacement and it is necessary to modify the electronics box!

Still, I can't recommend it.
It's new…
Full news…
So actually the bugs are still to be found and not all functions are 100% tested.

If you choose a board without drivers, you will need to buy some drivers.

If you want quiet operation, you need to focus on drivers with as many steps as possible.

The best choice is about anything from Trinamic. From them you can know TMC2208 , TMC2209 , TMC2130 , etc.
They have many other drivers on offer, but these are probably the best for home 3D printers.

What makes these drivers so good?

You control this driver as a driver with 16 micro steps, but in the driver these micro steps multiply to a beautiful 256, so the movement of the engine is almost smooth. For example, if you chose LV8729 (which will offer up to 128 native micro steps) and your board would not have a 32 bit architecture microcontroller, the microcontroller would have a lot of fun converting each motion to 128 micro steps. Often, this driver is used for the extruder motor because the TMC drivers without smart wiring work in quiet but not very strong mode. Without switching to SpreadCycle (aggressive silent mode), the extruder can lose steps.

If you buy a plate without drivers, I recommend to the axis XY and Z maybe even get a drivers TMC2209 and extruder (and possibly on the Z-axis) driver TMC2208 .
If there is a 4-5-piece TMC2209 offer, take it easy. It will only be better.

Why do not I recommend TMC2130 ?

Although they offer a lot of super features, their price is unnecessarily high from some vendors and what the newer TMC2209 offers.

Thanks to interpolation from 16 micro steps to 256, these drivers can be used on motherboards with 8 bit microcontrollers without worrying about lack of performance and freezing of the board.
It offers silent operation and, when connected via UART, the possibility of controlling the motor power via firmware. So you don't really have to disassemble the printer to increase your printer's performance. In addition, the driver can be switched to SpreadCycle mode. This is such a silent, aggressive mode that makes the engine no risk of losing pace and there will be no problem controlling the extruder motor.

Better versions of previous TMC2208 . In addition, it offers support for more powerful engines, less heat and allows collision detection. With collision detection, endstops can be removed from the printer and the home position can be detected by lightly hitting the end of the axis.

Very similar to the previous TMC2209 driver. It contains nearly identical features including collision detection. It does not use the UART protocol as a board connection. The connection takes place via a faster SPI protocol. Driver with native 128 micro steps. This allows you to select the number of micro steps between 2/4/8/16/32/64/128. If you decide to replace the extruder and choose the gear variant, you can choose a smaller number of micro steps. After all, the extruder will have to do 3x more movement. By reducing the number of micro steps, the extruder motor power is also increased.
