BAG 1

BAG 2

BAG 3

If you have the OmniaDrop Prusa edition follow the same instructions as the OmniaDrop standard version, they do not differ, if not otherwise stated.

STEP 1

Items from Bag 1:

 

  • 1 x M5x40

  • 1 x M5 washer

  • 6 x F683 ZZ ball bearing

Items from Bag 2:

  • 1 x M5 Sleeve

Insert three F683 ZZ ball bearings on one side of the Planet-Ring and three on the other side, like shown in the picture. Take the M5x40 screw and thread it through the Planet-Ring. Then place the M5 washer on the M5 screw and screw the M5 Sleeve onto the M5 screw. Tighten down the M5 Sleeve with a 8 mm wrench or pliers.

STEP 2

Items from Bag 1:

  • 3 x M3x14

  • 3 x Ring 5-3

  • 3 x M3 washer

  • 3 x M3 lock nut

Thread one of the M3x14 screws through the ball bearings of the Planet-Ring; make sure that the screw head is on that side where the M5 Sleeve is. Place one Ring 5-3 on the screw , then a M3 washer. Insert a M3 lock nut into a Planet-Gear and screw that Planet-Gear on the M3 screw. Repeat this procedure for the remaining two Planet-Gears.

STEP 3

Items from Bag 2:

  • 1 x 688 ZZ ball bearing

  • 1 x Threaded Hobbed Gear

  • 1 x M5 washer

Place the ball bearing on the M5 Sleeve and screw the Threaded Hobbed Gear onto the M5 screw (orientated like in the picture). Tighten the grub screw on the Hobbed Gear, to secure it. Now place the M5 washer on the M5 screw.

STEP 4

Items from Bag 2:

  • 1 x 688 ZZ ball bearing

  • 1 x M5 Sleeve

Insert the 688 ZZ bearing into the OmniaDrop-Main body and install the Planetary Gear system in the OmniaDrop-Main body. Use a screwdriver to lock the Planetary Gear from turning and screw the M5 Sleeve on the M5 bolt to secure the Planetary Gear shaft. Do not tighten the M5 Sleeve with a wrench otherwise the ball bearings will cant (jam). Just tighten the M5 Sleeve with your fingers.

STEP 5

Items from Bag 3:

  • 1 x M5 lock nut

  • 1 x M5 square nut

Use a screwdriver to lock the Planetary Gear from turning. Place the M5 square nut in the Manual-Wheel and screw it onto the Planetary Gear shaft. Using the 8 mm socket spanner secure everything with the M5 lock nut.

STEP 6

Items from Bag 3:

  • 1 x M4x16

  • 1 x M4 square nut

  • 1 x M4 knurled nut

  • 1 x Spring

Take the M4x16 screw and screw it into the OmniaDrop-Main body using the M4 square nut. Then screw the knurled nut onto the the M4 screw. Now place the spring on the M4 screw.

STEP 7

Items from Bag 2:

  • 2 x 683 ZZ ball bearing

  • 1 x Hobbed Gear

Items from Bag 3:

  • 2 x M3x25

Insert one 683 ZZ ball bearing on each side of the Hobbed Gear. Place the Hobbed Gear in between the two legs of the Idler and screw into place using the M3x25 screw. Please ensure that the orientation of the Hobbed Gear corresponds to the orientation in the image. Use the remaining M3x25 screw secure the Idler on the OmniaDrop-Main body (do not over-tighten the M3 screw). The Idler should now have a 10° angle to the OmniaDrop-Main body. This ensures the maximum possible grip for the filament and is intentional.

STEP 8

Items from Bag 3:

  • 1 x M3x45

  • 1 x M3 washer

Take the stepper motor and jiggle it into the Planetary Gear system. Use the M3x45 screw and M3 washer to secure the stepper motor. Before securing the stepper motor make sure the cables of the stepper motor are facing in the direction you want them to face.

If you have the BLTouch version you should now install your BLTouch on the OmniaDrop, using two M3x10 screws. The cables of the BLTouch should face toward the stepper motor.

STEP 9

Items from Bag 2:

  • Heatbreak

  • 0.4 mm Nozzle

Screw the Nozzle all the way into to ring heater and then unscrew it half a turn. Make sure the nozzle is screwed into the correct side of the ring heater like in the picture. Now screw the short thread of Heatbreak into the ring heater until it touches the nozzle. Use the supplied thermal grease and apply it to the long thread of the Heatbreak. You do not need to use all of the thermal grease just enough to cover the threads. Now screw the Hotend into the cooling block. Insert the thermistor into the ring heater and lock it using the grub screw on the ring heater.

STEP 10

Items from Bag 3:

  • 2 x M3x45

Use the two M3x45 screws to mount the cooling block onto the OmniaDrop-Main body. Make sure that the cables of the hotend are facing towards the stepper motor. If the Cables face the wrong way unscrew the nozzle slightly and orientate the cables correcly, then screw the nozzle back into the hotend.

Secure now the OmniaDrop standard version on your 3D printer carriage using the two M4x16 and M4 washers from Bag 3.  

STEP 11

Items from Bag 3:

  • 2 x M3x8

  • 2 x M2x6

Secure one of the blower fans with two M2x6 screws on the cooling duct. For the Prusa edition the blower fan needs to be upside down.

With the two M3x8 screws attach the cooling duct to the cooling block.

STEP 12

Items from Bag 3:

  • 2 x M2x6

Take the last blower fan and install it on the cooling duct. Use the two M2x6 screws to secure the blower fan.

If you have the OmniaDrop Prusa edition then continue here to finish up the installation.

LAST STEPS

First heat the hotend to 285°C. Once the hotend reached the temperature hold the hotend in place using pliers or a 12 mm wrench and tighten the nozzle using a 7 mm socket spanner or wrench.

To make make sure that the temperature is stable during printing do a PID autotune/calibration.

You also need to change the steps/mm value for the OmniaDrop Extruder in your firmware. To do this use the M92 G-code to set extruder steps/mm value and use the M500 store the values. 

For the 3 mm Filament OmniaDrop version the steps/mm value for the extruder is 560 steps/mm for 1/16 microstepping.

 

For the 1.75 mm Filament OmniaDrop version the steps/mm value for the extruder is 480 steps/mm for 1/16 microstepping.

If you have the BLTouch version then you need change probe-offset in your firmware since there is currently no G-code to implement the xy probe offset. For the OmniaDrop the BLTouch offset is X = 26.2 mm and Y = -31.3 mm.

 

PRUSA EDITION

Remove the old extruder from your Prusa. Attach the OmniaDrop extruder to your Prusa using zip ties and insert the GT2 belt into the intended slots.

PRUSA CABLE MANAGEMENT

Items from Bag 3:

  • 1 x M3x50

  • 2 x M3 square nut

  • 1 x M3x12

Wire all the cables (except the PINDA probe cable) at the bottom of the OmniaDrop-Main body and secure the cable to OmniaDrop-Main body using a zip tie, like shown in the image.

Attach the cable holder to the OmniaDrop-Main body using a M3 square nut and the M3x50 screw. Make sure to orientate the cable holder like shown in the image.

 

Attach the PINDA probe to the OmniaDrop-Main body using the M3x12 screw and M3 square nut. Wire the PINDA probe cable above the GT2 belt and then down to the cable holder.

 

Insert the Nylon cable guide in the cable holder and attach all the cables to the cable holder using three zip ties.

PRUSA LAST STEPS

Adjust the PINDA probe to the correct height using the method mentioned in the Prusa assembly manual.

Heat the hotend to 285°C. Once the hotend reached the temperature hold the hotend in place using pliers or a 12 mm wrench and tighten the nozzle using a 7 mm socket spanner or wrench.

To make make sure that the temperature is stable during printing do a PID calibration. You can find it in the LCD Menu

Calibration > PID calibration

To set the new steps/mm value for the OmniaDrop extruder create a G-Code file with the following two lines and run it on your Prusa:

M92 E960

M500

Under Settings disable the following two features:

Filament sensor   [off]

Fans check             [off]

In your slicer you need to add the following line to your Start G-Code, after the G80 mesh bed leveling G-Code:

G1 Y17.5 F3600

G92 Y0
