I am having a hard time trying to locate a correct diode for our pneumatic gripper some food valve. The valve is powered by 12Volts, but I just can’t seem to find anything that looks like Chris‘ picture. I have checked Digikey.ca but to no avail. can anyone point me in the right direction to acquiring a correct diode? thank you.

I am in the process of building the AR4 and noticed on page 176 of the manual that there is a J6 limit switch "tip". This is 3D printed and I can't seem to locate it within the zip file. Am I missing something? Thank you,

I have been designing a module gripper setup for a little while now. This is the prototype of the servo gripper. The mount and gripper have pogo connectors which allows for a quick swap if the user requires a different gripper. I hope to build 2 more consisting of a vacuum and pneumatic grippers. The vacuum gripper will hopefully accommodate dual suction pad grippers with dual mini vacuum pumps to operate each pad independently. I am currently sourcing parts for that one via AliExpress as it looks impossible to find suction grippers in Canada. if you have and criticism towards the build please let me know.
