Helping a friend set up his Photon and we're not able to get the test cube to stick to the bed. We're not hearing the layers "pop" so nothing seems to be sticking to the bed at all. We've tried increasing the bottom exposure to 80 and 100 seconds. We've leveled the bed several times using the paper method which works on my Photon, and we've also emptied the vat, tightened the FEP, and verified that the frequency is around 335Hz, which is within the recommended range. I didn't notice any extra layers on the FEP when we tightened it, so I don't think that's causing the issue either. We've verified that the UV light is working. Is this potentially an issue of a bed that needs to be sanded?
Update: 120 seconds seems to have worked, but seems excessive for Anycubic Green. I'll have him run an exposure test to get numbers he can use
