# Misc Tips & Tricks * You **must** use the glue stick to apply a layer of glue to the print bed before printing. If you do not, it may be more difficult to remove your part from the bed. Furthermore, repeated printing in the same portion of the bed may damage it without the protective layer of glue. * The bed should be leveled **every fifth print** for maximum print quality. If you aren't sure if the bed is level, go ahead and level it. * The timing belts that drive the print head along the gantry need to have their tension adjusted from time to time. MarkForged provides documentation on how to check and correct it. * If a file is uploaded to Eiger with the same filename as a previous file, the printer may append a number within parenthesis to the end. This may cause an error to be throw when selecting it to print. To solve it simply access the printer's storage like you would a USB and remove the appended number. * The printer will sometimes get stuck in a loop of printing a previously printed part regardless of what you selected to be printed. This can be temporarily solved by way of a power cycle using the switch on the back of the machine, however a far better solution is to flash, or refresh the firmware on the machine. To do this press the menu button on the touchscreen, enter the utilities tab and press the maintenance button. From there, press firmware recovery and it will ask you to perform a power cycle. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
