Mooz 2 uncontrolled temperature increasing


#1

Hi there!

I´ve been trying 3D printing in my Mooz 2 and I noticed temperature is increasing without control. I removed the printer module and when put out the parker fixing screw there are sparkles caused by 12VDC between the fixing plate and 3D module. I made test with the module dismounted and temperature does not increase but when I put the parker screw to fix the module to the fixing plate, temperature increase up to 270°C. I made a voltage measurement and there is 12VDC between fixing plate and 3D module. I opened the 3D module for checking cables and isolation and cables are correctly isolated, then I found when I put the test leads between heater body and fixing plate there was 12VDC too. So I would like to know how to solve this issue.
