Title: M8 does not work on RMHV3.1 [Print This Page] Author: Jeffery Time: 2022-3-5 07:31 Title: M8 does not work on RMHV3.1 M8 does not work on RMHV3.1. I found another person having the exact same issue on this forum, but no answer was listed. My firmware version is 2018-07-05-95. The front of my controller says it's RMHV3.1 but the front and back actually match the V2.1.
Please help. My machine is down as I can't turn the torch on.
Thank you,

Solved it. I was using an automotive 12V relay and for some reason the controller would not connect the M8 to ground. I changed to a 12V Micro relay and it works as expected.
