Like I said on the fb post, I’m using peopoly tough resin, with default settings (Smooth 50, Z Motor Speed 2, PM Motor Speed 10, PM Reset Position 80, Z Follows 2, Z Initial Speed 2, PM Initial Speed 10) Laser power I’ve tried with 58, 60 and 52, it always ends up like this.
I’m using b9 creator for supports and Asura for slicing, no chitubox anywhere, (that’s how bad the print is when you can’t recognise the supports )
I’ve also tried peopoly model gray resin and blue resin. It is not about settings or models or supports or slicers, because the printer was printing just fine before, and they were the same gcodes in the card. All models (gcodes) that worked before, now fail.
I think it might be something mechanical but that’s why I’m asking here and on facebook, because I cant figure out what it is. I was hopping either your tech support or someone else with experience, by seeing an object with that kind of defects might recognize the issue, and point me in the right direction.
I’ve checked all cables connections, leveling nuts, tilt platform, all seems ok.
Now my suspicions, the mirrors in the galvo seem to have a little bit of dust, but it’s almost nothing, could that be a possible reason? And if so, how to I clean them? Because all manuals warn you to never touch the mirrors in any circumstance.
Also, I have the PDMS VAT with FEP film on top, which I changed recently. No matter how well I get rid of bubbles, following this tutorial and this tutorial, they always end up reappearing after printing. Could that be the reason too? And if so, how do I avoid them reappearing? Everytime they appear, I have to remove the resin from the VAT, clean the VAT and loose the back screws and repeat the end part of the 2nd turorial.
I could really use the help.
