5015 Fan Ducts #

Our 5015 fan ducts are designed to be attached to the left-hand or right-hand side of the MultiMount base. They are height-adjustable and can be used with a wide variety of hot-ends.

  1. Loosely attach the fan duct to the MultiMount base using one M3x10mm button-head screw.
  2. Lower the nozzle to the bed.
  3. Adjust the fan duct so that the end of the duct is above the tip of the nozzle. For best results, the fan duct should be between 1 and 2mm higher than the tip of the nozzle. (Most printers include a set of flat wrenches/spanners for use during nozzle changes. These are often approximately 2mm thick and can be used as a spacer for setting a good height.)
  4. Insert the fan into the slot, then use one M3x22mm screw and one M3 hex nut to secure it in place.

EZABL Mounts #

Hardware Installation #

Our EZABL mounts are designed to be attached to the left-hand or right-hand side of the MultiMount base. They are height-adjustable and work with all of our EZABL sensors. Our 12mm “Mini” and 8mm “Micro” sensors will require the use of their included adapter rings.

  1. Attach the EZABL mount to the MultiMount System using one M3x10mm button-head screw.
  2. Remove the bottom retention screw from the EZABL and insert it into the mount. If you have the 12mm or 8mm EZABL sensors, first insert the adapter rings into the mount, then insert the EZABL sensor.
  3. Screw the bottom retention screw back onto the EZABL sensor and tighten to lock it into place.
  4. Follow our EZABL installation guide for proper height adjustment, calibration procedures, and testing.

Firmware Adjustment #

You will also need to adjust the nozzle-to-probe offsets so that the printer accurately knows the location of the EZABL relative to the nozzle. Choose one of the following:

  1. Use the M851 command to change the X and Y values:
    • Left-side mounts use: M851 X-40 Y-5
    • Right-side mounts use: M851 X40 Y-5
    • Ender 5/5 Plus left-side mounts use: M851 X-33 Y-9
    • Don’t forget to use M500 to save, and M503 to double-check that it was saved!
  2. Update/reflash your printer’s firmware with the new values:
    • In our Unified Firmware, enable the CUSTOM_PROBE option to enable the EZABL, then set your NOZZLE_TO_PROBE_OFFSET values as follows:
      • Left-side mount: { -40, -5, 0 }
      • Right-side mount: { 40, -5, 0 }
      • Ender 5/5 Plus left-side mount: { -33, -9, 0}
    • In other Marlin-based firmware, set your NOZZLE_TO_PROBE_OFFSET values as seen in our “Vanilla Marlin” setup guide using the following values:
      • Left-side mount: { -40, -5, 0 }
      • Right-side mount: { 40, -5, 0 }
      • Ender 5/5 Plus left-side mount: { -33, -9, 0}

5015 Fan + EZABL Combination Mounts #

This accessory consists of both a 5015 fan duct and an EZABL mount. This item is designed to be used on the left-hand or right-hand side of the MultiMount System.

  1. Follow the instructions for the normal 5015 fan ducts from the section above.
  2. Follow the instructions for the normal EZABL mounts from the section above.
  3. One of the last steps of the EZABL mount installation is to update the Nozzle-to-Probe offset values. Because this combination mount moves the sensor to a different position, you will use the following values instead:
    • Via direct command:
      • Left-side mount: M851 X-57 Y-4
      • Right-side mount: M851 X57 Y-4
      • Ender 5/5 Plus left-side mount: M851 X-59 Y-9
    • Unified Firmware: Enable CUSTOM_PROBE and set NOZZLE_TO_PROBE_OFFSET
      • Left-side mount: { -57, -4, 0 }
      • Right-side mount: { 57, -4, 0 }
      • Ender 5/5 Plus left-side mount: { -56, -9, 0 }
    • In other Marlin-based firmware, set your NOZZLE_TO_PROBE_OFFSET values as seen in our “Vanilla Marlin” setup guide using the following values:
      • Left-side mount: { -57, -4, 0 }
      • Right-side mount: { 57, -4, 0 }
      • Ender 5/5 Plus left-side mount: { -56, -9, 0 }

5015 Fan + BLTouch/CRTouch Combination Mounts #

This accessory consists of both a 5015 fan duct and a BLTouch/CRTouch mount. This item is designed to be used on the left-hand or right-hand side of the MultiMount System.

  1. Follow the instructions for the normal 5015 fan ducts from the section above.
  2. Follow the instructions for the normal EZABL mounts from the section above.
  3. One of the last steps of the BLTouch/CRTouch mount installation is to update the Nozzle-to-Probe offset values. Because this combination mount moves the sensor to a different position, you will use the following values instead:
    • Via direct command:
      • Left-side mount: M851 X-54 Y-19
      • Right-side mount: M851 X54 Y-19
    • Unified Firmware: Enable CUSTOM_PROBE and set NOZZLE_TO_PROBE_OFFSET
      • Left-side mount: { -54, -19, 0 }
      • Right-side mount: { 54, -19, 0 }
    • In other Marlin-based firmware, set your NOZZLE_TO_PROBE_OFFSET values as seen in our “Vanilla Marlin” setup guide using the following values:
      • Left-side mount: { -54, -19, 0 }
      • Right-side mount: { 54, -19, 0 }

“Sneaky” 5015/EZABL Micro Mount #

This accessory consists of both a 5015 fan duct and a Micro EZABL mount. This item is designed to be used on the left-hand or right-hand side of the MultiMount System.

  1. Follow the instructions for the normal 5015 fan ducts from the section above.
  2. Follow the instructions for the normal EZABL mounts from the section above.
  3. One of the last steps of the EZABL mount installation is to update the Nozzle-to-Probe offset values. Because our EZABL mount is in a different position, you will use the following values instead:
    • Via direct command:
      • Left-side mount: M851 X-20 Y-17
      • Right-side mount: M851 X20 Y-17
    • Unified Firmware: Enable CUSTOM_PROBE and set NOZZLE_TO_PROBE_OFFSET
      • Left-side mount: { -20, -17, 0 }
      • Right-side mount: { 20, -17, 0 }
    • In other Marlin-based firmware, set your NOZZLE_TO_PROBE_OFFSET values as seen in our “Vanilla Marlin” setup guide using the following values:
      • Left-side mount: { -20, -17, 0 }
      • Right-side mount: { 20, -17, 0 }

Strain Relief and Clamp #

Our Strain Relief accessory comes in two parts… the base and the clamp. The base itself has two grooves in it. Your hot-end wiring goes to the left inside the big groove, and the Bowden tube fits into the smaller groove. Due to the design, we recommend that you run your hot-end’s thermistor and heater out of the LEFT side of the hot-end for easier cable management.

  1. Attach the Strain Relief base to the top of the MultiMount System using two (2) M3x10mm button-head screws. Tighten securely, but make sure not to over-tighten!
  2. Gather the wires you intend to secure and hold them in place while you secure the clamp. The PTFE tubing runs through the smaller groove, and the hot-end and fan wiring can be run through the larger groove.
  3. Insert two (2) M3x12mm hex nuts into the back of the strain relief base, then secure the clamp to the front of the base using two (2) M3x12mm flat-head screws.

Clip-on Heatsink Fan Mounts #

Our clip-on heatsink fan mounts are designed to be clipped directly to specific hot-end heatsinks. These do not require any additional hardware, but must be used with their intended hot-end. For example, our V6-compatible mounts are designed to clip directly to heatsinks for hot-ends such as the Tough All-Metal hot-end and the standard E3D V6 hot-end.

  1. Attach the fan to the clip-on fan mount using four screws. You can usually re-use the screws from your existing fan shroud for this purpose.
  2. Press the clip-on fan mount onto the heatsink of your hot-end. It should snap onto the heatsink and remain in place with no additional hardware required.
  3. Arrange your wiring as you see fit. Be careful to ensure that you leave enough slack in the wire to account for the printer’s motion on all three axes, X/Y/Z.

Note: Some of our clip-on mounts will attach in a static position, but others are adjustable or have no set position. For best results, mount the clip-on duct as low on the heatsink as possible, but ensure that it is still fully secure against the heatsink. Mounting a clip-on duct too high may result in “heat creep”, clogging, under- or over-extrusion, or other problems.

Note: Ensure that you have the fan pointed in the correct direction before printing. The fan should be blowing directly into the duct and onto the heatsink. If your fan is blowing away from the duct instead of into it, remove and reverse the fan’s orientation, then reattach to the mount. Failure to ensure proper fan direction may result in “heat creep”, clogging, under- or over-extrusion, or other problems.

Top-mounted 40mm Heatsink Fan Mounts #

These fan mounts are designed to attach to the top of the MultiMount System and hang over the front, positioning a 40mm box fan in the proper place to cool the hot-end’s heatsink.

  1. Slide the fan mount over the top of the MultiMount System with the fan portion hanging over the front of the Multi Mount. Secure with two (2) M3x10mm screws.
  2. Attach the fan to the mount using four (4) screws. You can usually re-use the screws from the original fan shroud for this purpose.
  3. Arrange your wiring as you see fit. Be careful to ensure that you leave enough slack in the wire to account for the printer’s motion on all three axes, X/Y/Z.

Note: Ensure that you have the fan pointed in the correct direction before printing. The fan should be blowing directly onto the heatsink. If your fan is blowing away from the heatsink instead of onto it, remove and reverse the fan’s orientation, then reattach to the mount. Failure to ensure proper fan direction may result in “heat creep”, clogging, under- or over-extrusion, or other problems.

BLTouch Mounts #

Our BLTouch mounts are designed to be attached to the left-hand or right-hand side of the MultiMount System. They are height-adjustable and work with all genuine BLTouch and CRTouch devices.

  1. Loosely attach the BLTouch mount to the MultiMount System using one (1) M3x10mm screw.
  2. Attach the BLTouch/CRTouch to the mount using two screws.
  3. Follow the BLTouch/CRTouch manufacturers instructions to complete your installation.
  4. You may need to adjust the height of the BLTouch mount during your installation. Simply loosen the screw and position the mount at the proper height, then tighten the screw to secure the mount in place.

As part of the installation, you may be required to adjust the Nozzle-to-Probe Offsets values on your printer. The offsets for the BLTouch mounts are as follows:

  • Left-hand mount: { -27, -9, 0 }
  • Right-hand mount: { 27, -9, 0 }

Note: We do not sell, use, or support the BLTouch/CRTouch. We have a resource here that you can use to enable these devices in our Unified Firmware. Otherwise, you will need to rely on the manufacturer’s documentation for proper installation procedures. Our technical support cannot assist with the installation or use of these devices. If you need a replacement, we offer our EZABL Pro™ as an alternative.

Tough Extruder V2 Direct Drive Mount #

This accessory is designed to convert a Bowden setup into a Direct Drive setup based on our Tough Extruder V2.

Requirements: #

  • One (1) MultiMount System (base and clamp)
  • One (1) Tough Extruder V2, its included hardware, and a motor to match. We highly recommend a pancake stepper motor to save weight.
  • One (1) printed Direct Drive mount.
  • A hot-end that can accept a length of PTFE tubing, such as those with a PC4 fitting.
  • Two (2) lengths of PTFE or Tough Tube will be required. One length will run between the Tough Extruder V2 and the hot-end, the other length will be installed into the receiving end of the Tough Extruder V2. A standard 1 meter of tubing will be more than sufficient for these purposes. We will cut these to size during the installation. We recommended a dedicated PTFE cutter for this.
  • Zip ties for wire management, if desired.

Installation Instructions #

  1. Install the MultiMount System according to our installation instructions.
  2. Mount hot-end to the MultiMount System according to our installation instructions.
  3. Prepare the Tough Extruder V2 by doing the following:
    1. Install the Tough Extruder V2’s drive gear onto the motor shaft
    2. Test-fit the Tough Extruder V2 and motor onto the top of the Drive Drive mount. Use the exposed gear at the top of the extruder to manually turn the extruder mechanism and ensure it is moving properly.
    3. Once the motor and Tough Extruder V2 are fitting together properly, set aside momentarily.
  4. Use two (2) M3x10mm screws to attach the Direct Drive mount to the top of the MultiMount System.
  5. Insert a length of PTFE tube into the hot-end and ensure it is fully seated inside the hot-end.
  6. Insert the other end of the PTFE tube into the Tough Extruder. There will be excess tube between the hot-end and extruder. Measure the length of the tube between the mount body and Tough Extruder V2, and write this number down.
  7. Remove the tube from the Tough Extruder V2. From the loose end of the tube, measure and remove the amount you wrote down. This will shorten the tube to the length we need and automatically accounts for the length inserted into both the hot-end and Tough Extruder.
  8. Place the Tough Extruder V2 back onto the remaining tube and check fitment. The Tough Extruder V2 should now sit in the Direct Drive mount properly, and the tube should run from inside the hot-end to inside the Tough Extruder V2 completely.
  9. Use the three (3) long screws provided with the Tough Extruder V2 to attach the extruder and motor to the Direct Drive mount.
  10. Install a length of PTFE tubing into the top of the Tough Extruder V2 to ensure filament feeds into the extruder properly. The length is personal preference… you may choose to run a longer or shorter tube depending on where your filament spool is located.
Step 6: With tube fully inserted into both hot-end and extruder, measure from the MOUNT BODY to the EXTRUDER BODY
Step 7: Measure the length from the end and cut to size
Steps 8 and 9: Reinstall the extruder onto the tubing and attach motor to the rear
