Anycubic Photon Printer Owners 造訪社團 » 用戶發文

This is the first time I have printed a miniature without the base on it. I cadd'ed up a basic base in Fusion 360 and plan to print it in PLA. Whats the best way to attach a model like this to a basic round base? Should I just CA it to the base or should I try to pin the feet?

Thanks.

I wanted to share a mistake I made when replacing my FEP film.

I replaced my FEP film several days ago and since then I have had absolutely zero luck getting prints to stick to the build plate. I tried releveling many many times with different tensions on the paper from unmoveable to only slight resistance and everywhere in between.

I loosened my FEP sheet, and tightened it. I tried from 300 - 400 hz of tightness.

Nothing seemed to be working for me.

So I decided to take a very close look at what I done when replacing the FEP sheet since the printer was working very well before the replacement.

After cleaning everything thoroughly I began by inspecting the bottom of the vat. Here I noticed the critical flaw in my work. The FEP had indeed been stretched to the correct tension however I did not have enough initial slack in the FEP to allow the bracket to fully seat down into the vat walls. The bracket formed a lip around the bottom of the vat as it sat slightly lower than the bottom of the vat.

What I think was happening is that normally the FEP would be stretched around the bottom of the vat in such a way as to be the lowest point on the vat with it sitting underneath the inner var walls. So you would have screen -> FEP -> Vat stacked on each other with no room between them.

However in my configuration it was screen -> air gap ->FEP -> vat. So I postulate that the small gap allowed the FEP to be pushed down by the plate during printing and introduce enough Z movement into the system that there was too much space between the plate and the FEP sheet.

I then over tightened the FEP to the point that the bracket was seated properly but the FEP was now way too tight registering roughly 620 hz. Now prints reliably stick to the build plate but I expect I will have other issues with prints. I have a new pack of FEP arriving today and will do the swap properly this time giving myself plenty of slack to work with.

Just wanted to share an interesting thing that happened to me in case anyone else runs into the same issue.

Thanks.
