Problem with resin tank


Good evening.
I have been using a zortrax inkspire almost 2 years.
Now the problem is that I cannot change the Fep.
The dark screws are stuck. Trying to unscrew the screws, I even broke the screwdriver
The clear ones are still in good condition while the dark ones have rusted.
It seems they are made as an iron that is oxidized.
I ask for advice to solve the problem.


I had a similar problem with screws, although not on the resin tank. Upon calling the resin manufacturer and was told how to disolve the material. A quick way would be to use the UV cleaner couple time over.
