Laser Does Not Fire

I’m having an issue with a newly refurbished Form 2 I received. The printer goes through the motions like it is printing but I can never see the laser spot (with or without the build plate removed). Everything else looks great, I do not get a single error code, prints do not stick to the build plate and no failed prints or cured resin in the vat at all. I have tried factory resetting, updating (both the printer and Preform), and inspecting the printer in general with everything looking normal. Has anybody ever had this issue? I’m reaching out to Formlabs as it just came back from them but as a used printer I’m not sure what level of help I will receive. Any information would be greatly appreciated, thank you.
