30mA Current Meter

Hi does the board have a direct hookup for the 30mA Current Meter? I’m planning on purchasing. Thanks

Hi Kirk,

The mA meter is connected in series with the return wire from the laser tube to the the Laser power supply. Here is a write for the installation:


Oh thats awesome, I will take a gander at the links! I appreciate it. Also do you know or have any links I can get a mount or housing for the lcd screen. I just placed my order and super excited!

Search Thingiverse.com for it, I am pretty sure there are a couple of them on that site

We also have some instructions on our Knowledgebase, for reference: How to Connect an mA Meter


Thank you guys I appreciate the help! Now just have to wait for my parts to ship!
