• depending on your experience, allocate 40 min to 2 hours for the assembly

Motion Plane

• step 1: remove one row of the space

  

• step 2: solder the stackable header (don't add too much solder - keep it flat)

  

  

  

• step 3: solder the DC barrel jack (in the new board this is pre-soldered)

  

• step 4: solder-connect the UART pads on the TMC2209 SilentStepStick driver, all 3 pads can be connected but most importantly the top 2 should be connected

  

• step 5: solder header pins to the TMC2209 SilentStepStick driver

  (post soldering not shown)

  important: populate driver 1, 2 and 4 (instead of 1-3 in the image below)

  

• step 6: connect 12V and adjust V_ref to 0V so there's no current to the motor before the driver is initialized through UART

  

• step 7: solder the male header pin for the z-motor

  

Processing Plane

• step 0: solder the AMP mini CT 16 pin connector (ignore for now - to be updated)

• step 1: populate the header pins - don't forget the three female headers

  

• step 2: solder the male and female header pins, make sure not to leave any pin out

  

• step 3: mount stackable headers and the 4 spacers

  

• step 4: remove the Arduino (be gentle), stack the processing plane and solder

  

  

• step 5: connect the Arduino
