The E-stop is located in the SLB-EXT box.
Fasten the E-stop to the VFD Mounting Bracket on the side of the left table leg, using two (2) M5-16mm socket head screws.
If you did not purchase the Spindle Kit, you will use the E-stop mounting plate provided in the SLB-EXT box to fasten the E-stop to the side of the left table leg. The E-stop Mounting plate is inserted into the left pocket from the inside of the Table Leg with the two holes oriented toward the back of the machine.
Fastening E-stop into E-stop mounting bracket
Insert M5 nylock nuts into the E-stop mounting plate. Use two M5-16mm socket head screws to fasten the E-stop to the mounting plate.

Insert two (2) M5-10mm socket head screws into the two (2) holes under the “ALTMILL” cutout in the side of the left leg. Thread M5 T-nuts onto the screws, leaving the T-nuts loose.
Slide the SLB-EXT enclosure onto the T-nuts. The T-nuts fit into the T-slot from the left side of the SLB-EXT enclosure. Orient the enclosure such that the Sienci Labs logo is on the bottom left corner when looking at the acrylic face plate.
Tighten the M5-10mm screws, clamping the enclosure to the table leg.
Note: If you thread the M5 T-nut too far onto the M5-10mm screw you will have a difficult time sliding the T-nut into the T-slot of the enclosure.
Loosen the thumb screw on the front of the SLB-EXT enclosure and remove the acrylic face plate.
Fit the Z-axis and X-axis wire harnesses into the top cut out of the enclosure on the right side. Plug the sensor and motor control connectors into their respectively named ports.
Plug the two-pronged motor power connectors into the left most power ports. The power ports all supply the same output and therefore the connectors are able to be plugged into any, however, for installation purposes we recommend you to plug into the two leftmost ports while installing X and Z.

Fit the Y1-axis and Y2-axis wire harnesses into the bottom cutout of the enclosure on the right side. Plug the sensor and motor control connectors into their respectively named ports. It is important that you do not mismatch the control connector from one harness with the sensor connector of the other when plugging into one pair of Y1 or Y2 ports. If installed incorrectly you will encounter an alarm during operation.
Plug the two-pronged motor power connectors into the two rightmost power ports. The power ports all supply the same output and therefore the connectors are able to be plugged into any, however, for installation purposes we recommend you to plug into the two rightmost ports while installing Y1 and Y2 power.

Reinstall the acrylic face plate of the SLB-EXT onto the enclosure. Tighten the thumb screw by hand.
Reinstalling acrylic cover
Plug the green connector of the E-stop cable into the port labeled E-stop on the right side of the controller, and the other side of the cable into the E-stop.

If you have installed the Sienci Labs Spindle Kit, plug the clear connector of the spindle control cable that is attached to the VFD unit, and plug this into the port labelled ‘RS485’ on the left side of the controller.
If you’re installing your own spindle, you may need to connect your own spindle control cable as explained here.
Plugging spindle control connector into RS485 port
Plug the green connector of the 48V power supply into the port labelled Power.
Plug the power supply into a 110V outlet.
