Im almost complete with the conversion on our machine (homebuild) except for wiring the VFD. I have the power to the power supply. The stepper motors illuminate red but the masso does not turn on. I will check the cable with a volt meter tomorrow but was wondering if anyone has any ideas. ---

This is our final steps before packing it up is plug everything together, install firmware, and run a series of tests. Only thing i can think of, and i’m sure you arlready did this… is the cable between the power box and the masso plugged in? There’s a 6-pin black connector. One side is female, other is male. This sends power and proximity switch signal from the power box into the Masso Touch controller. Other think i can think of is i wonder if the fuse in the masso touch has blown for some reason. It’s easy to see, open it up and theres a thick red wire in the upper right with a car-style barrel fuse. ---

So the 36v outlets are hot but the 24v are dead. Anything inside the power box to look for? ![1000024597](https://canada1.discourse-cdn.com/flex011/uploads/pwncnc/original/2X/0/07d3ef93925ddf20928b6d108a41ad423a4f7eb6.jpeg) ![1000024598](https://canada1.discourse-cdn.com/flex011/uploads/pwncnc/original/2X/d/d6897f066c7041f963a3e71a17c8cc520db027a8.jpeg) ---

The 24’s should be attached to a power distribution board. I suppose it’s possible a ferrule came out. The power supplies are relatively simple inside. you should easily be able to figure out what’s going on after it’s open. Please let me know so i can adjust our building procedure and checks. ---

Thats all it was. The yellow cable was off the distribution board. Back in business. I did take an extra 1/16 off the insulation to get it to stay. It kept wanting to push back out as I was tightening the screw. ---

Perfect… thank you for digging into that. I will pass this info onto our Scott who assembles these to ensure we take that extra step. ---
