I am not alone after all!
We’ve been printing large parts with custom supports with V2 for a while and it was perfectly fine. Recently we were forced to switch to Clear V4 just as you and we haven’t been able to print any of the parts we previously did. We are printing them straight onto the platform and after first few layers, things go really weird.
I’ve been in touch with support for 2 weeks and they haven’t given any possible solutions.
As I am typing this, I am printing out some test parts for comparison with Clear v4, Clear v2 (some leftovers) and Gray V3. So far it looks like the V4 is the faulty one. What I want to try after the V2 print finishes, is to print some V4 with V2 settings (using old V2 vat and V2 cartridge but with V4). I’ll let you know how that goes.
UPDATE: Here’s a gallery timeline of our prints with print settings for each one… https://photos.app.goo.gl/KpqlkFuQLfCAOXyD2
Did you say that V4 at 0.1mm prints just fine? We might as well switch to 0.1 then for the time being since our production has been halted for past 2 weeks just because of these issues…
