Stage 01: Driver and Motor Cable

Plug the second extruder cable into position on the control board.

This cable came with the Axis printer and should already have been installed during the main build.

If you have a TMC2208 Driver skip to step 4.

The stepper drivers are the most delicate part of the Axis 3d printer and it is why we've also included a spare. Before opening, make sure that you are grounded (touch a large metal object) to avoid any chance of static damage.

Prepare the A4988 Stepper Driver by removing it from its packaging and sticking the heat-sink to the black chip.

Make sure that the heat-sink is not touching any of the pins. Orient the fins of the heat-sink as shown.

Adjust the trimpot so that flat side is pointing left as shown in the second photo.

Check also that you have three jumpers installed like shown.

Install the stepper driver onto the control board in the position shown.

Make sure that the driver is orientated with its trim-pot pointing away from the power terminals. Plugging it in the wrong way round will destroy it.

The TMC2208 upgrade comes with either 3 or 6 drivers. If you have three you can use two on the x/y axes and keep one as spare, if you have 6 you can use them on the X/Y/Z/E1 (and E2 for dual extrusion) and have one spare.

Prepare the TMC2208 stepper drivers by removing them from their packaging and sticking the heat-sink to the top.

Make sure that the heat-sink is not touching any of the pins. Orient the fins of the heat-sink as shown.

The photos shown these drivers being installed on the X/Y axes, the process for installing on the E2 position is identical.

To install the TMC2208 drivers you will need to make sure that there are no jumpers plugged in at the stepper driver locations on the control board.

You will however need to make sure that there is one jumper placed on the UART pins for each axis you have a TMC2208 installed.

Plug the TMC2208 driver into the positions shown, make sure that the trim-pot is pointing towards the power terminals, installing the driver the wrong way round will destroy it.

Note, the trim-pot doesn't need adjusting as these drivers allow us to control the current via the firmware.
