MINI Linear Sound Test

prusaprinters

The gcode files here are not 3d models being printed, instead they're for people either diagnosing their machine, or their setup.IMPORTANT: READ THE PRINT INSTRUCTIONS.These test codes are for diagnosing and finding vibrations, noises, etc on the X or Y Axis. They allow you to have a quick test to find out which is causing any noise, resonance, etc. and at what speed it happens. They can also be useful to test how soundproof your enclosures or other setups are.LinearTest1.gcode;Homes the machine, centers the Z axis at 90, then moves X from 0 to 180 and back, then Y 0 to 180 and back at speed intervals 20, 40, 60, 80, 100, 150, 180, and 200mm/s. This helps identify which axis is causing noise, and at which speeds.LinearTest2.gcode;Homes, centers Z, then moves X/Y both from 0 to 180 and back in sync. X length is reduced to match Y length to ensure the stepper motors are in sync with speed and direction.LinearTest3.gcode;Runs exactly like LinearTest2, except it moves X out to 180 to get different overlapping frequencies. Changing the distance means the steppers run at different speeds to reach the given point. This one is most helpful for determining enclosure soundproofing, along with LinearTest5.LinearTest4.gcode;Runs LinearTest2 with X/Y reverse of each other. X starts at 0 and moves to 180, Y starts at 180 and moves to 0. This is to blend the stepper motors synced, but spinning in opposite directions.LinearTest5.gcode;Runs LinearTest3 with X/Y reverse of each other. X Starts at 0 and moves to 180, Y starts at 180 and moves to 0. This last one really drives home the annoying tones the MK3S can make, even makes stealth mode a bit annoying. For those who seem wary; Open the gcode file in your favorite text editor, such as notepad++. You can see all the code is done in sections, the starter block with acceleration and jerk limits pulled from Prusaslicer, followed by the printer identifier block and parameters, then the movement block itself, followed by the standard end gcode block from prusaslicer to include all the safeties such as turning off the heaters, motors, resetting flow, etc. Everything is commented in the files.
