Worming problam

Hi all, the Formlabs 3 printer stays in the preprint stage while the temperature is not going up and stuck around 29-degree celsius even after one hour, please advise,

Thank you,

Turn up the heat in the room the printer is in. A few degrees should do it. Or move the printer to a warmer area. Or take a big cardboard box and put it over the printer so there’s a little insulation between the printer and the rest of the room.
