Started the masso for first time and recieved the usual alarm for the emergency lock warning. I cleared that and tried to home button but got a new alarm that states motors. I looked at all the step motors and saw the both red and green lights are lit. How do i clear this alarm so i can home machine for the first time? ---

You need to power off and power on the controller to clear motor alarms. ---

Did that and did the same. ---

Couldi have blown a fuse on the controller cause a black screen on the masso? ---

Is your screen completely off, or is it just not displaying anything? I had an issue with my Masso screen once, but I could tell that the screen was receiving a signal because it would change to a slightly different shade of black when I powered the machine on. I ended up disconnecting and reseating the cable that connects the Masso controller to the screen, on the controller end. Could also be a blown main power fuse, as the motors are on separate fuses and would remain powered if the controller loses power. ---

The first time I fired up mine, I also had the alarm. Come to find out one of the fuses 5 fuses were blown. I just moved the one setting off the alarm to the last connector (The one without an arrow) and everything was fine. Once I changed the fuse on the blown one everything was fine after that. ![image](https://us1.discourse-cdn.com/flex022/uploads/onefinitycnc/original/3X/f/b/fb6b50a41e821af2898030eab0dfec5179f76682.png)
