Unpack the ER11 DC spindle, 36V power supply, and mounting bracket assembly kit. Package contents: (1) ER11 spindle, (1) 36V DC power supply, (1) bag containg 4 M4 bolts, 4 M4 nuts, 4 panhead philips screws, 8 washers, and 4 mounting bracket halves Not included: (1) 115v AC power cord

SpindlePackageSteps Step 002
Step 002

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

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.

SpindlePackageSteps Step 004
Step 004

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

Locate the screw terminals labled "N" and "L" which stand for neutral and live.

SpindlePackageSteps Step 006
Step 006

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.

SpindlePackageSteps Step 007
Step 007

Using at least 14 AWG guage wire strip approximatly 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.

Layout the mounting bracket halves and the panhead philips screws

SpindlePackageSteps Step 010
Step 010

Loosly assemble each of the two bracket halves using the panhead screws. keep the halves loose to enable the insertion of the spindle later in the assembly process

Insert the 4 bolts into each of the predrilled holes on the brackets

SpindlePackageSteps Step 014
Step 014

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.

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

SpindlePackageSteps Step 021
Step 021

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.

SpindlePackageSteps Step 022
Step 022

properly seated endmill in the collet

SpindlePackageSteps Step 023
Step 023

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

SpindlePackageSteps Step 024
Step 024

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

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

SpindlePackageSteps Step 027
Step 027

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.

SpindlePackageSteps Step 028
Step 028

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.

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.

SpindlePackageSteps Step 030
Step 030

Find the negitive spindle power wire connected to the "V-" screw terminal

SpindlePackageSteps Step 031
Step 031

Disconnect the negitive power wire from the "V-" power supply screw terminal

SpindlePackageSteps Step 032
Step 032

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

SpindlePackageSteps Step 033
Step 033

Find the relay screw terminals next to the usb connector on the breakout board

SpindlePackageSteps Step 034
Step 034

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

SpindlePackageSteps Step 035
Step 035

If you are using the PWM spindle speed controller, simply clip the positive and negitive 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 cliped wires to the screw terminals marked "M1" and "M2" respectively.
