Swapper3D Instructions

Mount the Swapper to the printer

Turn off and unplug the printer

  1. Turn the power switch of the printer to the OFF position (yellow arrow)
  2. Unplug the power cable from the printer (Green arrow)
  3. Unplug the power cable from the wall (Red arrow)

Update the arduino firmware to the runtime

Instructions:

  1. Update the adruino with the latest runtime firmware
  2. The xloader will have all the settings saved from the last time you used it, and on windows machines the port will stay the same between pluggin the usb into the arduino each time, so you can probably use the settings as they are when you open xloader.
  3. Get the latest HEX file release from the gitHub repository and save to your downloads folder
  4. Plug the USB cable into the Arduino
  5. Use Xloader, select the port (find the port in device manager if it’s not set already)
  6. Select the hex file you just downloaded to your “downloads” folder
  7. Click the upload button
  8. If you don’t remember you can refer to the primer on Arduino Firmware
  9. You can unplug the USB once the firmware flash is successful. You will know because the xLoader will show the number of bytes uploaded along the bottom edge of its window
  10. If the flash is successful the LCD screen will update as per the picture below “Ready to Swap!”

Attached the swapper body to the x end idler

Instructions:

  1. Move all the wires to the right side of the main body so they don’t get pinched
  2. Match the three(3) mounting screw holes in the Swapper main body,
  3. with the three(3) holes on the X-End idler (Red arrows),
  4. Then insert three(3) M3x10mm socket cap screws (pink arrows) and gently tighten
  5. From the rear of the printer,
  6. Insert three(3) more m3x10mm socket cap screws and snug (green arrows)

Attach the Tool Holder to the HR servo

Instructions:

  1. Remove the center screw from the HR servo horn (red arrow)
  2. You will need to match the two(2) holes on the Tool Rotate (HR) servo (yellow arrows), to the larger holes in the center of the bottom of the tool holder wheel (green arrows)
  3. Loosely Screw in the off-center m3x10mm socket cap screw first
  4. Then rotate the tool wheel until the hole lines up with the servo horn hole underneath
  5. insert the second m3x10mm socket cap screw
  6. Tighten both screws

Add the tool holder sticker

Instructions:

  1. Peel the back half way off the sticker
  2. center the sticker in the middle of the tool holder wheel
  3. align the number “1” on the sticker with the indented line on the outer circumference of the tool holder wheel (red arrow and circle)
  4. smooth the sticker from the center to the outer edge
  5. as you pull the backing paper off, continue to smooth the sticker down and squeeze out any air bubbles

Connect the button wires

Instructions:

  1. Using some needle nose pliers, Squeeze the wire metal connectors (yellow arrow)  to make them a little tighter
  2. Press the connectors onto the switch/button metal connectors (red arrows)
  3. NOTE: it does NOT matter what connector goes on which pins, just as long as both wire connectors are connected to the switch
  4. NOTE 2: The connectors should fit snugly. If they don’t, even after you squeezed them, you can use the needle nose pliers to squeeze them while they are on the switch terminals.

Lower the print head all the way down

Instructions:

  1. By pressing down on the horizontal X smooth shafts, closest to the left and right ends (yellow arrows)
  2. the print head will move down
  3. Press until the nozzle is close BUT NOT TOUCHING the print bed

Tie up wires

Instructions:

  1. Note 1: Securing the wires to the LCD bezel was moved up, Don’t worry about it not appearing in these photos.
  2. NOTE 2: Throughout these steps MAKE SURE to leave enough slack in the servo wires and button wire for when the head is all the way down to the print bed AND when the cutter arm is all the way rotated into swapping position AND when the tool arm is all the way rotated into swapping position.
    You can check that the wires are loose enough by adding the zip tie and then manually rotating the cutter-arm and tool arm through their ENTIRE motion to make sure the wires have some looseness.
    You may need to raise the printer head up & down (by pushing down on or pulling up on the X-axis smooth shaft respectively)  as needed to make space to check the wire lengths. Up for cutter-arm and tool-arm, and down for overall wire length.
  3. NOTE 3: remember that as you go, you may remove the labels if they are in the way. It’s good to keep them on as longer as possible to help you remember which servo is which.
  4. Try to untangle the wires as much as possible
  5. Run the QL wire over top of the CR servo and zip them together (green arrows)
  6. Run the wires for CA, TL, and WA (WA only if you have a palette) up the right side (orange arrows)
  7. LEAVE ENOUGH WIRE SLACK FOR THE CUTTER-ARM and TOOL-ARM to MOVE through their entire range of motion!!!!!
  8. Zip the QL, CR, CA, TL, and WA (WA only if you have a palette) to the hole on the main body (blue arrows)
  9. Bring the Switch, TR and TH wires into the bunch for ‘QL, CR, CA, TL, and WA’ and zip to the other hole on the main body about 1inch from the last (Yellow arrows)
  10. Since the wires are all different lengths there will be loops of wire. 
  11. Bunch the wires together and fold the extra over
  12. Then zip tie the wires at regular intervals
  13. it doesn’t matter if the wires are tangled
  14. and it doesn’t matter if there are overlapping zip ties
  15. just make it as neat and tidy as you can. The wire wrap in the next step will hide the mess.
  16. At the last zip tie, at the top, bunch up the TR servo wire make it come out the top of the bunch (Red Arrows) bunch up any extra.
  17. While wearing safety glasses, and using side-cutters, trim the ends off all zip ties.

Add wire wrap

Instructions:

  1. Remove all the remaining labels from the servo wires.
  2. NOTE: the wire wrap may seem too long at first. While you are wrapping it you need to twist it.
    To twist it properly, hold the lowest part with your left hand,
    and with your right hand twist it at different spots moving you right hand upwards after each twist.
    This will secure it better, and shorten it, and may it look smoother and less wrinkled.
  3. Place the cloth wire wrap over the wire bunch
  4. Twist the wire wrap until it’s smooth and the correct length.
  5. Zip tie at the top and bottom

Attach the end effector safety guard

Instructions:

  1. Pull the print head up, by pulling up on the X axis smooth shaft
  2. Secure the end-effector safety guard to the tool-arm with two(2) M3x10mm socket cap screws
