Error # 803 ant #904

Hello,
This morning my machine refuses to work (it worked normally on Monday) - error # 803 fail to start preview mode. In the guide, (https://support.flux3dp.com/hc/en-us/articles/360001791895) it is noted to restart the machine but it did not work so I click on the link # 904 homing failed - in maintenance I click on home and move but it doesn’t work. we hear the noise but the arm does not move. Have you ever had this problem? I have an order to finalize urgently.

Sorry - nothing here. Probably open up a support ticket. I have had the 803 before and some noise at start up but they seem to resolve themselves.

Latest firmware and BeamStudio?
