[Material retracting S5 Bundle]

My apologies. It was blocked. Schoolboy error, trying to over complicate the solution

[Material retracting S5 Bundle]

The material is going 300mm past the decoupler and halfway up the printer back before retracting.

 

The tube is definately not blocked I'm afraid

I am now unable to load material into the second head. 

 

The PVA goes through the flow meter by about about 100m then immediately unloads right back into the material station then error codes ER 52 and ER63

 

I have swapped the flow sensors from head 1 to 2 and disabled them in the software but no luck.

 

I give up!
