Trouble printing on new phenom L

using deft gray
and the default settings for this printer in chitubox
I keep getting failed prints that seem very under cured and the bottom of the vat except where the print was has a layer of cured resin that I then need to scrap off

There is no problem with the screen. When printing, select the heavy-duty support for the support setting, and select the default setting for other support settings. Try not to add subraft settings. If printing fails, please filter the resin before use.
