Last new post from me today - I’ve been saving them all up!
I had a problem when homing the machine - it would move just fine, but when it got to closing the light gate sensor it would throw a Homing error alarm / B motor alarm.
I didn’t find any mention of this on the forum so I wanted to post my findings and solutions:
I was running my machine in direct sunlight - the IR light coming from the sun was overwhelming the optical sensor. The solution was to stick a bit of tape over the sensor to keep the light out. Super easy, and I’m sure this will help someone out some day.
