Topic: Drivers too hot
Hey guys. Been having a lot of problems with my printer lately. I thought I had them all fixed but things are actually getting worse. I'm using a Prusa i3, ramps 1.4 and drv8825's on all my drivers.
During a print my x motor shut off and the y motor continued. I attested this failure to a thermal shutdown on the drivers. They got extremely hot and so did my motors.
So naturally, i turned the vrefs down today. I didn't use the measurement way but i turned them down until the motors wouldn't run then turned them up a little bit. Now the drivers and motors are getting hotter quicker so much that i cant run the x motor more than 50mm without a shutdown(i'm still thinking thermal shutdown because once it rests for a minute i can repeat the process).
I have no clue what to do. And yes, to turn down the vref i turned the pot counterclockwise. I don't have a fan blowing directly on the drivers. Any clues as to keep everything from shutting down and why, even at minimum vref, everything is too hot? I barely ran my printer for ten minutes when it shut down. I'm desperate for answers
