c) Install one cable tie down onto the left plate just below the upper strain relief along the right edge of the Z-Brake as pictured.
d) Install the second tie down just under the bottom left board mounting standoff, oriented along the bottom edge of the EinsyRetro. The tie down should be flush with the left edge of the EinsyRetro as pictured.
Plug in motor leads to the EinsyRetro control board as follows:
First locate the 4 pin Molex connector labeled “X Motor” and plug it into the board as pictured.
Locate the 4 pin Molex connector on the lead with grey jacket up to the connector; this is Y-Motor. Connect it to the board as pictured, to the left of the X-Motor connection.
Locate the two 4 pin Molex connectors with red and black heatshrink, these are Z-Motors. Connect these two to the left two connections on the Z-Brake board as pictured.
Locate the 4 pin Molex connector labeled “E Motor” and plug it into the board as pictured.
Connect Z-Brake Motor Harness [AS-CB0070] to the right side connection of the Z-Brake board. Connect the other end of the Z-Brake Motor Harness [AS-CB0070] to the EinsyRetro control board as pictured.
Connect the Extruder & Bed Heater leads to the EinsyRetro board as follows:
Locate the 2 pin terminal block plug labeled “E Heater” and plug in as pictured.
Locate the two red fork terminals labeled "Bed Pwr";
Using a Phillips screwdriver, loosen the lower two terminals on the EinsyRetro board
Insert the fork terminals into the two lower terminals (polarity irrelevant) and re-tighten the terminals securely using a Phillips screwdriver. Torque the terminals to 15 in*lbs.
Locate the 3-pin Molex connector labeled "Z-Max" and connect to the board in the location shown.
On the harness exiting the bottom of the left plate, locate the single white wire connected to pin 1 of a 3-pin Molex connector
On the harness exiting the left frame plate above the control board, locate the single un-pinned green wire and connect to pin 2 of the connector on the white wire you just located.
Now connect this to the Z-Min connector on the EinsyRetro board, as pictured.
Locate the two pin Molex connector labeled “E Therm” and plug in as pictured.
Locate the two pin Molex connector labeled “Bed Therm” and plug in as pictured.
Locate the three pin Molex connector labeled “24V Fan” and plug in as pictured.
First put an M3 lock washer [HD-WA0035] onto the ground post on the left plate above the EinsyRetro control board.
Next install the ring terminal of the TVS Diode wire onto the ground post.
Install the ring terminal of the X motor ground wire onto the ground post.
Install the ring terminal of the Y motor ground wire onto the ground post.
Install the 2 ring terminals of the Z motors ground wires onto the ground post.
Install the ring terminal of the Extruder motor ground wire onto the ground post.
Install the 2 ring terminals of the Chassis Ground Extension [AS-CB0082] onto the ground post.
Use a 5.5mm nut driver and an M3 Nyloc Nut [HD-NT0001] to fasten all of these wires onto the ground post.
