I’m having trouble running pva on my dreamer. When l feed it into either of the heads the drive just keeps clicking and nothing much comes out of the excluders. I have try running from temperature from 190 To 240, at 240 the pva did start to come out of the excluder, but the clicking did as well. Anyone have any ideas? Can you get faulty PVA. I am using Excelvan Professional 3D PVA Dissolvable Filament 1.75mm.
If you can’t feed even regular PLA/ABS filament and are hearing clicking that sounds like it’s jammed. Mine does that from time to time - I have to take the extruder apart and clean it up (some say that even a small particle can cause a jam). Another thing I’ve seen is that filament claiming to be 1.75mm is not actually that size if you measure it with a caliper.
You might need to raise the temperature above the 240 C range. You might need to clear out something in the nozzle. This might be a clogg/jam. Also try to clean the hobbled bolt and the extruder assembly. If the 1.75 mm filament is not within from ±0.10 mm do not use it because it is bad. In addition, is the filament chewed, if you can post some picutres of the removed filament?
The machine is only 1 week old and has no troubles feeding ABS or PLA. But that a good point about the size of the filament, l will get some calipers and give it a check. Will let you know how l get on. Thanks

I have tried raising the temp above 240, but when l put it up to 245 the machine gets to 242 and stops. The label on the reel says running temperature is 190 -210. Also the reEl is chewed where it is pushing it in.
If you live near Lockport you can always swing by my office in downtown Lockport - I have a caliper and all the tools to take apart the Dreamer. We can also try running it through my Dreamer and see if it jams mine as well (I have a Flashforge Creator Pro and a Flashforge Dreamer in my office).
Thank you for your very kind offer, but if it lockport in the USA then l a few thousand mile away in the UK.
Eh it is only a small pond between us right?
Do you run any cleaning filament through before you switch to a different filament? Sounds like a clog to me.
hello,
I use PVA on my flash forge cretor pro. with 200° 1800mm/s and retract 3mm
before loading PVA, i load a PLA at 230° to clean nozzle, after, down temperture to 200° and load PVA
if you use printer with PVA more than 200-210°, PVA will burn into nozzle
sorry for my English, i’m french
To dry the product, the only solution I use is a convection oven at 50 ° C
But I do not know if it is compatible with the PVA. We should try by winding wire 1 meter on a small coil to ensure it does not stick to itself.
