Unplug the regulator and connect a +24 V voltage source to the inputs and a multimeter to the outputs (measure DC voltage). Adjust the output voltage to 9 V using the screw on top of the potentiometer.

  • press button P20 to power-on PCB

Assembly

Soldering the mainboard components

Front view of an empty mainboard v1.3

The assembly of the board is tricky as some components have been packed tightly - especially those below the motor drivers.

The following table lists each component to be placed by hand along with other components that might collide. Collisions marked with a '?' are hard (but still possible) to solder if the components are not placed in the right order. Those without a '?' are impossible. The table has been sorted to provide a practical order for soldering: low components come first and components blocking each other are in the right order. Similar components and spatiality has been used to form groups.

Soldering the Voltage regulator

Just insert four 1-pins into the corners. It's pretty easy if you insert the module into the main board while soldering.

Plug the voltage regulator into the PCB and make sure the orientation is right!

basically what you do for the first operation is:

  1. remove arduino and all plug-in modules
  2. remove the DC/DC jumper (JP1, pwr 9v)
  3. add a switch (or jumper) to P20 (button) and make it permanently switched on
  4. connect battery - LED +24v should be ON
  5. using a voltmeter, adjust the DC/DC converter output voltage to 9V DC (or 8V which is better for the 5v voltage regulator to produce less heat)
  6. after getting DC/DC module output 9v (DC), remove battery and install all modules, activate jumper JP1 - PCB can be switched on using P20 and is ready for programming now

Soldering the RTC

Just insert a 5- and a 7-pin-row into the module. It's pretty easy if you insert the module into the main board while soldering.

Soldering the motor drivers

For each of the both drivers: Insert a row of 18 stacking pins (the longer ones) row into the mainboard. Insert 6 separated stacking pins into the mainboard. Try to put the module onto those pins and solder them.

Putting everything together

If you stick everything together, you have something that should look roughly like this:
