Hi - I have a form 2 with tough 1500 - which has been sitting for 6 months or so (in the semi dark), as I’ve been working on other things.
Coming back to it - my small models keep failing, and I realised I’m finding it very difficult to understand the print failures. (To be fair my success rate from new tank and new resin has been 30% at best- and I’ve never used the machine for anything else - so I’m pretty sore the problem is me not the machine).
I’ve stirred up the resin in the tank - and the models nearly printed - but I suspect my issue is I don’t really know how to orient the part / arrange supports - but then again could the resin have gone off ?
I have found it difficult to track down a really good fault finding guide for what to do if prints fail. I have read the guidelines so understand about Inclining prints - supports being needed “for over hangs” and “bridges” working portly - but how would I know if mininrafts or full raft is better for example -
When should I increase the size of my supports / touch points?
Can I tell from looking at features from the failed prints? And if so what precisely? Are there any guides anyone could link to for analysing and “debriefing” failed prints ?
For example - two identical models on different bits of the build plate- One had become detached from the build plate, at perhaps 15% of the model, the other 80% printed and didn’t detach …
So I’m trying printing out with a full raft to see if that works better …
I’ve tried uploading pictures (from my phone) but it keeps claiming the pictures are too large. Grrr !
I e tried auto orientation auto supports in preform - and that certainly leads to failed prints …
Help!
Thank you …
