Clicking sound - same here… Brand new printer, but ONLY after changing the first tank out - no problems until then.
So there’s a couple of things I’ve observed and just want to ask if you have the same.
First tank/cartridge combo I let the printer fill with Clear resin… It took FOREVER with multiple dispense error timeouts, but I managed to print off a few things without any clicking whatsoever.
Then I changed tanks and cartridge to Tough 2000 (also both brand new), and installed exactly the same way. The only difference then is I noticed the same slow filling so decided to half-fill by hand and let the printer do the rest.
The printer then complained that the tank had expired?! (it’s brand new out of its shrink wrap, the only difference is that it now had some pre-filled resin).
That’s when I first noticed the clicks, just before printing, like others reported.
The same thing happened when I switched to another tank and Draft V2 (again both brand new), again, I pre-filled somewhat, and let the printer fill the rest, again the printer complained it was an expired tank.
Clicks at start of print on that one too.
So I guess my question is (and it could be totally unrelated but worth asking in case it is something of interest) - when the clicking occurs, did you pre-fill the tank or let the printer do it, and did you get any expired tank warnings?
