Inspira Imperial Quilting Frame Assembly


Attaching your Husqvarna Viking Mega Quilter 18x8 encoders to the Inspira Imperial Quilting Frame

The Mega Quilter 18x8 includes a stitch regulator that works like the Quilter’s Cruise Control, so you will not need a Quilter’s Cruise Control with the Mega Quilter 18x8. Encoders attached to the frame carriages will sense the movement of the machine. A wire will connect the encoders to the machine to let the needle know to go up and down at the right speed (fast or slow) to achieve a perfectly regulated stitch length.

A. Attaching the Lower Carriage Encoder

You will need the following tools and parts to install the first encoder on the Lower Carriage. The parts come with the Mega Quilter 18x8:

4 mm Allen wrench Open-end adjustable wrench Long bolt Wheel (This is on the lower carriage. You will be removing it & replacing it in the directions to follow.)

Washers (3) Encoder Encoder brass ring insert Nut (This is on the lower carriage. You will be removing it & replacing it in the directions to follow.)

Lower Carriage


Turn your lower carriage upside down. You will be placing one encoder on the lower carriage. The bolt and wheel will be removed.

The bolt will be replaced with a longer bolt. The wheel will be assembled back on the longer bolt along with the encoder and parts as described below.

Using your Allen wrench and the open-end adjustable wrench, remove the bolt holding the wheel. Save the nut. We will use it on the longer bolt to hold the encoder and wheel in place.

Notice that there is a right and a left side to the wheel. The right side, as pictured, will be placed against the metal wall of the carriage in the following steps.


Insert the brass ring inside the hole of the encoder arm.

Place the long bolt through the hole on the carriage (where the shorter bolt was removed).

Place the wheel on the bolt (keeping the right side pictured above next to the metal wall of the carriage).

Place two flat washers on the bolt.

Place the encoder on the bolt. The brass ring should be inside the hole on the plastic arm of the encoder. Notice the position of the encoder. The ridged wheel on the end of the encoder should line up with the wheel on the bolt.

Place another washer on the bolt, followed by the nut.

Tighten the nut.

Viewing the Encoder through the Hole in the Lower Carriage


You have completed the installation of the lower carriage encoder.

B. Attaching the Upper Carriage

Encoder

You will need the following parts to install the encoder on the Upper Carriage:

Nut Nylon spacers (2) – these

may be clear, black, or mixed.

Encoder Shoulder bolt

The encoder attaches to the wheel with the longer screw


There are three holes between the two single wheels on one side of the upper carriage. (The other side of the carriage has double wheels.) (This will also be on the same side of the carriage as the QBOT Y-axis drive assembly—you may not have attached this yet.) Two of these holes are close together. Of the two holes that are close together, you will be placing an encoder in the hole closest to the wheel.

Turn your upper carriage upside down.

Place the encoder on the shoulder bolt.

Add the two nylon spacers to the shoulder bolt.

Place the shoulder bolt through the outside wall of the upper carriage.

Attach and tighten the nut on the inside wall of the upper carriage.


This is a picture of the upper carriage with the encoder and QBOT drive assembly attached. (The QBOT drive assembly will be attached after the encoders.) Although it is difficult to see in this picture, the encoder does not touch the QBOT drive assembly.

This is a close-up view of the encoder on the upper carriage. The encoder is lying away from the wheel assembly and towards the front of the carriage. (The QBOT drive assembly is also pictured. It will be attached after the encoders.) Notice that the ridged wheel of the encoder is riding along the black track of the frame. There should be no debris of any kind on the encoder wheel or the black track of the frame. The wheel should turn smoothly as it rides along the track on the frame.


C. Attaching the Encoder Wire

You will need the following items for this part of the installation:

The upper carriage with encoder installed The lower carriage with encoder installed One encoder wire (included with your Mega Quilter 18x8)

It is best to use tweezers to attach the encoder wires to the encoder. The wires should be tightly seated in the slot of the encoder. Note that the flat edge of the white piece goes toward the arm of the encoder. The ridged edge of the white piece (visible in the photo) goes away from the arm of the encoder.

The upper carriage encoder with wire connected is pictured. The ridged wheel of the encoder is seated on the black track of the frame.

Close-up of fully inserted wire


The lower carriage encoder with the encoder wire connected is pictured. The ridged wheel of the encoder is seated on the black track of the frame. The encoder wire comes up through the opening in the carriage.

Before installing your Husqvarna Viking Mega Quilter 18x8 on the Inspira Imperial Frame, it is time to begin the installation of your QBOT. The encoder wire end that attaches to your machine will remain loose at this time.


Installing the QBOT drive assemblies on your Inspira Imperial Frame You will need some additional parts and hardware (in addition to the parts and hardware that come with QBOT) to install QBOT on the Inspira Imperial Quilting Frame with the Mega Quilter 18x8:

Part # 140 00 32-36 – Frame Adapter Kit for QBOT. This includes additional hardware (washers, spacers, etc.) to install QBOT on the Inspira Imperial Frame.

Part # 140 00 32-38 – QBOT 3’ & 8’ Wire Kit. This is needed if you are setting up your frame at either the 3’ or 8’ width.

Part # 140 00 32-59 – Wiring Harness QBOT 18x8. This longer wiring harness also omits the Quilter’s Cruise Control cords that are not needed for the Mega Quilter 18x8.


Installing your Husqvarna Viking Mega Quilter 18x8 on the Inspira Imperial Frame

Place the non-slip pad on the upper carriage.

Watching to make sure that your encoder wires are out of the way, center your Husqvarna Viking Mega Quilter 18x8 on the upper carriage (on top of the pad). It should be centered front to back and side to side.

With your machine turned off, it is time to connect the encoder wire. Be careful not to bend the pins when connecting the wire to the machine.

The next three pages will guide you through the following steps:

Install the light fixture on your Mega Quilter 18x8. Install the four spool thread rack on your Mega Quilter 18x8.

Install the front handles of your Mega Quilter 18x8. This photo shows all of the above attached along with the QBOT wiring harness. Your QBOT wiring harness is not attached yet.


Set the Controller dials for both the left and right handle to the “3 o’clock” position as a starting point.

It is now time to complete the QBOT installation on your Husqvarna Viking Mega Quilter 18x8.


Installing the QBOT Wiring Harness on the Mega Quilter 18x8 Part No. 140 00 32-59

NOTE: The wiring harness that came in your QBOT box fits the original Mega Quilter; it will not be used for the Mega Quilter 18x8. Make sure you have the Mega Quilter 18x8 wiring harness, Part No. 140 00 32-59, which is longer and different.

Remove the upper screw from the front handle mount on the Mega Quilter 18x8. Use the screw that comes with the wiring harness to secure the QBOT mounting bracket (Figure 1). Next, tilt QBOT so that you can read the display clearly.


TIP: If you are setting up your frame for the 5 foot width, you might find it helpful to use sticky back hook and loop tape to attach your QBOT power supply to your machine. If you are setting up a 10 foot frame, this would take too much cord, and you would not be able to reach across your frame.


Apply strain relief pads to your Mega Quilter 18x8 as pictured to tidy your wires. The bobbin winder will remain functional by avoiding this area.

Note: Fabric has not been loaded on your quilt frame yet.

The Y-axis wire has been placed between the machine base and the carriage clamp.


Final Preparation of your Husqvarna Viking Mega Quilter 18x8

Remove the protective cover over the needle at this time.

Oil your Husqvarna Viking Mega Quilter 18x8 following the instructions below.


Check To Make Sure You Have the Latest QBOT Firmware Version


QBOT Parameters and Settings for the Mega Quilter 18x8 You must change two parameters in QBOT because you have installed it on the new Inspira Imperial Frame (the “X Axis Direction” and the “Y Axis Direction”). There are also settings that need to be changed in QBOT because you will be using it with the Mega Quilter 18x8. These parameters and settings customize the way QBOT operates for your machine and frame. The correct parameters and settings for operating QBOT on the Inspira Imperial Frame with the Mega Quilter 18x8 are on the following page. Instructions to change the parameters and settings on QBOT are also included. NOTE: Parameters and settings will need to be changed each time you update QBOT with a new firmware version.

QBOT Parameters and Settings Inspira Imperial Frame and Mega Quilter 18x8


Changing the Parameters and Settings in QBOT

Congratulations! You have completed the assembly of your Inspira Imperial Quilting Frame, Mega Quilter 18x8 encoders, and QBOT. It is time to install your fabric, setup your Mega Quilter 18x8 for stitching, and do a test to make sure everything has been installed correctly. (You’ll notice that you still have Bungee Clamps leftover. These will be assembled in conjunction with your fabric installation).


Repeat going into the setup section of QBOT for each parameter or setting. When all parameters and settings have been changed, press ‘STOP’ to return to the ‘Quilt/Record/Options’ menu. Cycle the power for QBOT by turning the power off and then back on again.

Loading Fabric on the Inspira Imperial Quilting Frame


Setting up your Mega Quilter 18x8 for Stitching

The next few pages review bobbin winding and threading your sewing machine. Wind and insert a bobbin and thread your sewing machine following these instructions.

Set the Stitches per Inch and Speed settings on the handle Control Units at the 3 o’clock position.


Turning On Your Mega Quilter 18x8 and QBOT

To engage ‘Auto Stitch’ on your Mega Quilter 18x8, press and hold the ‘Auto Stitch’ button on the left handle of your Mega Quilter 18x8.

Continue pressing the ‘Auto Stitch’ button with your left hand, while you use your right hand to turn the power on your Mega Quilter 18x8.

Continue pressing the ‘Auto Stitch’ button. Listen to hear a sequence of beeps. The final (third) beep will sound continuously until you release the ‘Auto Stitch’ button.

QBOT may be powered on either before or after you turn on your Mega Quilter 18x8.

QBOT Test with the Mega Quilter 18x8

The next two pages will guide you through a test to make sure that QBOT and the encoders on your Mega Quilter 18x8 have been installed correctly.


If the QBOT Test does NOT move in the correct direction (clockwise, starting in the lower left-hand corner), here are three things to check:

Make sure the drive wires are wrapped around the drive assembly drive wheels correctly. The wire on the upper carriage should wrap around the TOP of the drive wheel. The wire on the lower carriage should wrap around the BOTTOM of the drive wheel.

Make sure the QBOT parameters and settings have been changed for the Inspira Imperial Frame and Husqvarna Viking Mega Quilter 18x8 (see page 43).

Make sure the X and Y-axis cables are plugged in correctly If your test moved in the correct direction, your QBOT has been installed correctly. If your test moved in the correct direction, but you have questions about the stitching, here are three things to check:

Make sure you turned on your Mega Quilter 18x8 following the instructions on the top of page 57 so that Auto Stitch is engaged.

Make sure you started stitching the test following the instructions starting on the bottom of page 57. You want to start the needle moving before starting QBOT. The encoders will normally starting moving the needle as they sense movement of the carriage. The reason you are starting the needle before QBOT begins moving the carriage is so that you do not miss the first few stitches of your design. You want to start QBOT immediately after the needle starts moving; otherwise, the encoders will recognize that the carriage is not moving and they will automatically stop the needle.

Move the carriage while looking at the encoders to make sure the encoder wheels are turning. If one set of encoders is not turning and running on the track smoothly, the stitches will not look good in that direction.

If your stitches are too short, turn the dial on the left controller to the left. If your stitches are too long, turn the dial on the left controller to the right. The dial is sensitive to slight changes.

Additional instructions for stitching with your QBOT and operating your Husqvarna Viking Mega Quilter 18x8 are on the remaining pages. Enjoy!
