Hi I had using my printer (Anet A8 with Marlin) for about 2 years now and today weird problem accured. Temperature sensor varies in very strange way so I replaced it (it was slipped and touch directly to heater so I assume its broken). But after that my Z home goes another direction (away from limit switch). When I manually pressed it it works (checked in pronterface with M119). Also when I manually move Z axis it goes in good directions. I have no idea what happened here. Another weird thing is when I z home and it goes in another direction, hit limit swtch with my finger nothing happened, it still goes. Can somebody help me?
