I have a stock ft5 setup and firmware. My printer has worked flawless for the last year. This last weekend it started acting up. I home all and z goes down but wont come back up to home. I home just Z and it goes down and still doesnt go up. I manually lift the bed to home it and then I can the home it a few times and it starts the same thing again. The only thing I can think of is my Z endstop button is sticking to stop it form coming up, Has anyone else experienced this?
