ER65 Flow Sensor Error

[gsuty17 0]

Good Afternoon,

 

I am being plagued with an inordinate amount of issues on a very low hour machine, purchased as a bundle.  I consistently get a debilitating ER65 error about 10 minutes into my print.  Replaced both print heads, checked the feed rollers, updated firmware.  Everything looks good.  Keep in mind, this machine has maybe 200 hours on it total.  Any ideas?  The machine has been dormant for maybe 6 weeks prior if that has any bearing on the situation

 

I am new to Ultimaker and hobby grade machines but use a Stratasys F120 frequently.  I can tell you there is a WORLD of difference between the two.  Not real stoked right now.

What filament types are you using? If for EG you are using PVA and the printer as been left for 6 weeks with the PVA spool on it, you will for sure need to dry out the PVA because it will have become wet and that would also make problems with the flow sensor due to the PVA being wet and not flowing right.

 

When you get the error, is the number 2 print core in the down or up placement, this will help limit the sensor error to just one print core side, if the error always happens with the number 2 print core nozzle being in the same placement.
