Getting Started Safety First Safety is your responsibility. Always use the proper protective equipment and "safety sense" when building or operating a CNC Engraver. Engravers have high voltage power supply. Router bits rotate at high speeds and have cutting edges that are hazardous. The operator should understand the hazards and take appropriate safety precautions before operating the engraver. Please review the entire assembly instructions before beginning building the E3 CNC engraver. 3

4 Required Tools To assemble the kit together you will need the following: ½ end wrenches or pliers A pair of long nose pliers to hold the nuts Diagonal Cutters or sharp knife to trim nylon ties Calipers or measuring tape to measure part placement. Small standard screwdriver to connect electronics Small Phillips screwdriver to mount home switches and stepper motors Medium Phillips screwdriver to build the main components Sand paper to remove laser marks on the faces. Tools you may need for the electronic setup include: 25 to 40 watt soldering iron Multimeter to correctly connect the power supply and stepper motors. The multimeter is also a good tool to have for general electronic trouble shooting. To complete the E3 CNC router you will need: Computer with control software for GRBL Build material Router bits Dry lubrication such as graphite, Teflon or silicon spray Building the E3 CNC Engraver We recommend a large flat working surface for assembling the router. All screws (unless noted) should be installed snug, then rotated 1-1/2 to 2 turns. Light sanding of the wood surfaces will clean up the marks made by the laser. Sanding, painting or stain and clear coat will give the router protection. Quick start and troubleshooting guides are available and can help you get up and running.

5 1. Z Spindle Mount Assembly Parts list for the Z spindle mount assembly: A. 4 SG20U bearings B. 4 M6 X 25 mm screws C. 4 M6 nuts D. 2 Brass nuts 5/16 E. 1 Washer 5/16 F. 2 Anti-backlash rubber washers 5/16 G. 1 Threaded rod 5/16-18 H. 2 Z frame support I. 1 Z frame J. 2 Z spindle mount support K. 1 Z spindle bottom mount L. 1 Z spindle top mount M. 19 M4x16 screws N. 19 M4 nuts O. 1 DeWalt 660 spindle 1. Apply dry lube (graphite, Teflon or silicon) on the threads. We recommend monthly application dry lube for normal use of the E3. Dry lube is a good choice for dusty environment of the CNC. Applying dry lubrication can be completed at a later step before using the E3. 2. Install the anti-backlash nut assembly in the order shown. Brass nut > rubber washer > steel washer > rubber washer > brass nut 3. Snug up the brass nuts so that the flats are parallel with each other. Find the best pair of flats that allow the threaded rod to move and with minimal backlash. 5

6 This step is critical to ensure that the motor has enough torque to drive the Z axis with minimal backlash. The optimal flat selection is as loose as possible without axial movement of the threaded rod. 4. Insert the steel washer into both Z frame support slots ensuring that the brass nut flats remain parallel. The fit into the wooden slots will be tight. 5. Place the assembly into the back mount and retain with 6 M4 x 16 screws and nuts. 6

7 All screws (unless noted) should be installed snug, then rotated 1-1/2 to 2 turns. The screw should turn freely and yet not have any axial play. It is important to find the best pair of flats that allow the threaded rod to move freely with minimal backlash. (see step 2) 6. Place the bottom engraver mount into the back mount and retain with 5 M4 x 16 screws and nuts as shown. 7

8 7. Remove collet from the DeWalt spindle. 8. Remove the 4 screws on the bottom part of the DeWalt and remove the main head. Be careful not to let the black mount on the end of the DeWalt slip out of the yellow housing. If this happens you will need to remove the top cover and remove the motor brushes. Then you can reinsert the spindle shaft and re-install the brushes. Pease see our troubleshooting guide for instructions on removing and with replacing bushing. Please see troublehooting guide at BobsCNC.com. Do not try to insert the motor shaft without removing the motor brushes. This will damage the DeWalt brush mount and the router will not function correctly. 8

9 9. Place the top mount over the DeWalt and slide it into position 10. Place the DeWalt into position. The top mount will need to be compressed into the correct position so that the slots on the frame are aligned with the top mount tabs..
