Re: Part of the build area doesn't print the base of supports

I recommend to everyone to get the new steel build table. Calibration is a breeze and eliminates one issue altogether.

Re: B9 v1.1 *Upgraded 3 VATS & Resin

Might need to rethink your price. V1.2 are selling for this or less, and they are higher resolution and print almost twice as fast. Just a thought.

Re: Steel buid table sticking problems (edited)

If I were u I would still use the steel bench block for calibration, u do need some down force to calibrate properly. One thing I forgot to ask. When the screws are loose does the new build table "Float" freely in the slots to allow the table to move freely upon contact with the PDMS? Robe...

If u can make a calibration print that sticks to the build table and not damage the PDMS then when u print a model it doesnt' work then something else is wrong. It's not the build table.

Re: Steel buid table sticking problems (edited)

With the weight of the steel build table make sure u don't press the table very much against the PDMS when u calibrate. Also don't over tighten the screws. I have never heard of a stainless table being not flat. Sounds like something else is going on. You should not have to calibrate settings on the...

Re: Yet another frustrating printing problem

Get the build table. Even if u sand the original table flat u can still warp it if u over tighten.

Looks like what Mike says about your focus.

Many hrs doing this. All surface modeling (nurbs). Don't do t-splines, clayoo, or z brush. Printed on the core 530 at 40z just to show client model. Now I have to print again and try to cast this beast. Robert Howle Yamaha racer 1.JPG Yamaha racer no farring.JPG Motorcycle 1.jpg Motorcycle 2.jpg

Re: Yellow prints cracking

If this is happening in the same location on the build table then check for finger prints or smudges on the bottom of the vat (glass). Also make sure there are none on the vat film itself.
