Restep A1

Restep is an add-on board for Recore A6 and Recore A7 which gives it an extra TMC2209 stepper driver. This is great if you want to build a 3D-printer with 7 motors, like the Voron 2.4.

Pinout diagram

Mounting Restep on Recore

Restep must be mounted in two different ways, depending on how the 6-pin header is soldered.

1. If the pin header is soldered on the component side, the board should be mounted so that the 4-pin header where the stepper motor connects is pointing out the same way as the permanently mounted stepper motors.
2. If the pin header is soldered on the bottom of the PCB (where no components are soldered), the 4-pin header where the stepper motor connects should be pointing in towards the center of Recore.

Choosing address

Note

It is only necessary to change the address if you are going to use two Resteps on a Recore A6

If you only have one Restep board mounted on Recore, you do not have to alter it in any way. The default UART address will then be 3. If you want to add one more board, you can cut the lines on AD0 which will give the board address 2. Address 0 and 1 are reserved for stepper 4 and 5 which are mounted on the board on UART3(pins PD0/PD1).
