I purchased a BBL H2D Combo over the weekend (at Microcenter). After running the initial calibration sequence, the AI Assistant immediately informed me:

• Please clean and lubricate the X-axis linear rail, YZ-axis linear rods, and the extruder lift linear rail.

• Threaded rods need lubrication now.

This is not my first Bambu Lab printer, but I have never been asked to start maintenance before my first print on the device.

Do you think this is specific to my printer or has BBL started requiring this on all new H2Ds or printers in general?

I visually inspected these rails and lead screws and saw plenty of lubrication on them.

I recently tried setting up a 1000VA (600W) UPS to power my P2S. I got a quick lesson in how many watts a P2S (alone) actually pulls when starting a print job. Bambu Lab says the P2S can draw a maximum of 1000W (@ 110v). Thus to be able to utilize a UPS, just for power to the printer (not the AMS units, etc.), it has to provide 1000W minimum and should probably provide 1200W to be reliable (sweet spot).

I am now mulling over whether the printer really needs UPS protection that will cost roughly half as much (or more) than the printer's initial cost.

Is anyone using a UPS with their P2S? Is there a real need? How well does Bambu Lab's "Power Loss Recover" system work?
