ER11 DC Spindle with 36V Power Supply - zentoolworks/cnckits GitHub Wiki
STEP 1

STEP 1: Unpack the ER11 DC spindle, 36V power supply, and mounting bracket assembly kit.
Package contents:
- 1 x 115v AC power cord
- 1 x ER11 Spindle
- 1 x 36V DC Power Supply
- 1 x Hardware Bag (4 x M4 bolts, 4x M4 nuts, 4 x panhead philips screws, 8 x washers and 4 mounting bracket halves
STEP 2

STEP 2: Remove the 36V DC power supply from its box, then remove the protective plastic cover that covers the screw terminals.
STEP 3

STEP 3: When the spindle power supply is shipped, the voltage selector is usually set to 230v for European power. Changing this option is simple, using a screwdriver push the switch to the 115v position.
STEP 4

STEP 4: Be sure to verify that the voltage selector switch located on the side of the spindle power supply is set to the 115V setting for the United States.
STEP 5

STEP 5: Locate the screw terminals labled "N" and "L" which stand for neutral and live.
STEP 6

STEP 6: Using a number 2 Philips screwdriver loosen the screw terminals labled "N" and "L". Using the supplied AC power cable, strip approximatly a 1/2 inch of the insulation from the wires. Connect the AC power wire that has the imprinted writing to the "N" screw terminal, and the remaining wire to the "L" screw terminal.
STEP 7

STEP 7: Using at least 14 AWG gauge wire strip approximately 1/2 inch of the insulation for use in connecting the spindle to the power supply. If you intend to use heat shrink tubing, slide some onto each of the power wires before soldering the spindle lead wires to the extensions.
STEP 8

STEP 8: After soldering the spindle lead wires the the 14AWG extension, slide the heat shrink tubing over the solder joint and heat the tubing to protect the connection.
STEP 9

STEP 9: Layout the mounting bracket halves and the panhead philips screws
STEP 10

STEP 10: Loosely assemble each of the two bracket halves using the pan head screws. keep the halves loose to enable the insertion of the spindle later in the assembly process.
STEP 11

STEP 11: The 2 loosely assembled brackets.
STEP 12

STEP 12: Prepare the four M4 nuts, bolts, and the 8 washers for assembly. Place one washer on each of the four bolts.
STEP 13

STEP 13: Insert the 4 bolts into each of the pre-drilled holes on the brackets.
STEP 14

STEP 14: Align the bolts with the holes on the Z axis mounting plate, and seat the bolts through the holes, place one of the remaining washers on each of the bolts.
STEP 15

STEP 15: Once the brackets are aligned tighten the bolts using a hex head key and a wrench.
STEP 16

STEP 16: Spindle bracket assembly.
STEP 17

STEP 17: Slide the spindle motor through the opening in the bracket assembly and align the bottom of the spindle motor flush with the bottom of the bottom bracket.
STEP 18

STEP 18: Using a number #2 philips screwdriver tighten the bracket screws until the spindle is secured in place.
STEP 19

STEP 19: Completed spindle bracket and spindle assembly.
STEP 20

STEP 20: Removing and tightening the spindle collet requires 17 mm, and 13 mm metric wrenches. place the 13 mm wrench on the keyed portion of the spindle shaft to secure the shaft. using the 17 mm wrench loosen the spindle nut that holds the collet in place. Now you can insert or remove an endmill.
STEP 21

STEP 21: Insert an endmill into the collet, be sure to insert it into the collet far enough to secure the endmill when tightened, but not so far that the shank of the endmill hangs out the back, or the flutes are covered by the collet.
STEP 22

STEP 22: Properly seated endmill in the collet.
STEP 23

STEP 23: Hand tighten the collet nut and collet onto the spindle shaft to ensure that the collet nut is not cross threaded.
STEP 24

STEP 24: Firmly tighten the collet nut using the 13mm, and 17mm wrenches. Tighten firmly, but don't over tighten.
STEP 25

STEP 25: Properly seated endmill in the collet, tightened on the spindle ready to cut.
STEP 26

STEP 26: Find the "V+" and "V-" screw terminals, these are the 36 volt output for our spindle.
STEP 27

STEP 27: Connect the ends of the 14AWG power wires to the power supply using a number #2 philips head screwdriver. Black goes to the "V-" screw terminal, and red to the "V+" screw terminal.
STEP 28

STEP 28: Be sure there is nothing around the spindle, double check your wiring, plug the power supply into a surge protector the flip the switch on the surge protector to test that the spindle powers on properly. After testing turn off the surge protector and unplug the power supply.
STEP 29

STEP 29: To connect our spindle to the relay on our breakout board which enables software control of the spindle on/off M-code commands, we will need a length of the at least 14AWG guage wire and a number #1 flathead screwdriver.
STEP 30

STEP 30: Find the negative spindle power wire connected to the "V-" screw terminal.
STEP 31

STEP 31: Disconnect the negative power wire from the "V-" power supply screw terminal.
STEP 32

STEP 32: With the spindle negitive disconnected, connect the length of wire to the now unpopulated negitive screw terminal.
STEP 33

STEP 33: Find the relay screw terminals next to the USB connector on the breakout board.
STEP 34

STEP 34: Using a number #1 flat head screwdriver secure the length of negative power line from the power supply to one of the terminals, and the negative power line from the spindle to the other. Ensure that the negative lines are secured and in the correct location on the breakout board, failure to do so can damage the electronics.
STEP 35

STEP 35: If you are using the PWM spindle speed controller, simply clip the positive and negative spindle wires between the power supply and the spindle. than connect the power supply side to the input side of the PWM module marked "+" and "-" respectively. Connect the spindle side of the clipped wires to the screw terminals marked "M1" and "M2" respectively.
STEP 36

STEP 36: Breakout board powered up and connected to the controller.
STEP 37

STEP 37: Complete spindle assembly with PWM and relay controlled on and off.
