| + | This guide will only work on the 1.1.9 Marlin firmware for the JG A5, which is in beta and may have extra bugs. | ||
| + | |||
| + | A 1.1.8 version may come out if someone else is willing to do one on the wiki however I don't use 1.1.8 | ||

| The most noise comes from the Y-axis and the X-axis. Because the Z-axis rarely moves when printing you do not hear much noise. The TMC2208 can deliver less power than the standard A4988 driver. One Z-axis driver needs to power two motors at the same time. The avaliable motor current is divided between both motors. \\ | The most noise comes from the Y-axis and the X-axis.
