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.

Mounting it on Recore

Restep should be mounted so the stepper is pointing upwards and the 6 pin header is pointing down. The 6 pin female header goes into the header on the board marked S6 or S7.

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).

In this example, the X-axis is routed to S6. Only the relevant changes are shown.
