Cabling and Wiring

This section refers to the connections between the potentiostat and the printing chamber. This information is particularly useful for troubleshooting connection problems.

General arrangement

In the system, high quality, insulated LEMO connectors are used to link the different components. The general arrangement is depicted below.

Legend

= 4 pin connector ¦ = 3 pin connector ¦ = female connector ¦ = male connector

The components are the following, in order of connections:

Component	LEMO Connector
Potentiostat	4 pin female
System cable (potentiostat side)	4 pin male
System cable (sledge, on system)	3 pin female
Printing chamber (sledge, on system)	3 pin male
Printing chamber (plate)	custom electrodes

Note

To measure a connection with a female LEMO pin, insert a piece of stiff wire in the pin.

System cable connections

Each pin on the system cable is dedicated to a specific electrode.

Legend

WE = Working Electrode, RE = Reference Electrode, CE = Counter Electrode

Printing chamber cable connections

Legend

WE = Working Electrode, RE = Reference Electrode, CE = Counter Electrode

From the LEMO connector three wires connect directly to the electrodes in the printing chamber. The color convention for the wires is indicated in the figure.

Testing the connections

After assembly, we suggest to check the connections from the 3 pin lemoplug to the printing chamber. The resistances should be as follows:

1. The working electrode substrate to the bottom left pin. Target <10 Ohm
2. The counter electrode to the bottom right pin. Target <10 Ohm
3. The reference electrode to the top pin. Target <10 Ohm
4. The working electrode substrate to the counter electrode. Target >1 MOhm
5. The working electrode to the reference electrode. Target >1 MOhm
6. The counter electrode to the reference electrode. Target >1 MOhm
