Optimizer going out

When trying to print a long job on 3600 the optimizer head gives an “optimizer reseat” error. It will do this every 30-50’ in a print. When this first started we would get the error about once a day, but now it’s progressed and is impossible to get a roll of usable material. After looking at a past post in this forum I have changed the FI towers but this has not helped at all.

I actually signed up to comment,

I got the same problem at my work on one of the machines I run.

I had it fail 8 times in a row yesterday. I managed to get it working by wiping the contact points with iso alcohol. very frustrating.

the tech we had onsite at the time said the board could be going out.

Hi @lriley13015,

For the issue you are describing, I suggest contacting your service representative.

#2 Replacing the board was one of the first things i tried and at first it didn't seem to be helping any, along with changing the FI towers. Then we ended up having a bigger issue with our optimizer electro valve. After changing that out and also changing out the intermediate tank it seems the issue has been better, might be worth looking at/ trying if you continue to have problems with it.
