Hi Aaron, that connector can be disregarded. The manufacturer included it but it is not used on the AXIS.

Please contact us at info@makertech3d.com for a replacement fan.

Check that the jumpers under the drivers are connected properly. Double check that the TMC boards are plugged in the right way round. More info can be found on the help centre: https://www.makertech3d.com/apps/help-ce...

On the 2S it’s just plug and play. It’s difficult to say which direction to set the trimpots with out knowing the specific make of the driver. What it’s set on as default should work OK. Adjust in both direction in small 1/6th turns if you find you’re getting skipped steps. Just make sure when plugging in that the EN pin on the driver matches up with what’s on the control board.

The remaining slots need to be filled with three A4988 drivers to control the other motors.

This is normal. The first layers printing temp is a little higher to help with adhesion to the platform.

The Axis doesn’t have an on/off switch, so it would have to be from the mains.

Powering off and on again will reset the printer. If the problem persists then the hotend thermistor will need replacing, please contact us at info@makertech3d.com for replacement.

There are two blue arrows pointing to the UART jumpers. They are also marked on the board itself and the connectors are colour coded green.

Is the shaft firmly connected to the coupling? If you’re certain the motors isn’t turning at all try swapping the driver for another known working one and do the same with motors cable. You can email us directly and we can help you with sending out a replacement part if need be! info@makertech3d.com
