Gantry Assembly and Setup
Zaber's gantry products require some assembly and set-up upon arrival. These gantries can be disassembled, packed, and transported for use in new locations, or re-configured with new motion control axes to suit new applications. To set up your gantry, complete the following steps (where applicable).
Note: Instructions are provided for all hardware variants used in different gantry configurations. Not all hardware will be used in your configuration. Section headings will contain applicable part numbers.
Contact Zaber Customer Support at any time for help or additional information.
Preparation
- Unpack the high-flex motor cables and hang them vertically by one end for 24 hours to relieve packaging stresses. If the cables are too long to be hung up in one piece, loosely coil them on a flat surface into a large diameter such as 60 cm (2 ft).
- Unpack the brackets, tools (provided with AP200 or AP201 cross-members), cable guides and other hardware.
- Keep fasteners with their labelled bags to easily identify/locate the correct fastener for a step.
- Unpack the stage axes and identify the two identical X-axis stages, Y-axis stage and any additional axes you may have.
- Determine your mounting surface. The instructions provided assume a metric optical breadboard is used to mount the X-axis stages (or optional risers). See Product Overview for determining stage spacing and recommended breadboard dimensions.
- Determine stage orientations and locations of cable guide(s) and controller. The controller is typically located on the end of the gantry near the motor cable connections on the peripheral devices. It's preferable to mount it closer to X-axis 1, as this axis will mount to the cable guide. If the controller is required to be mounted at a significant distance from the gantry, longer cables or cable extensions may be necessary. See MC10T3(Lxxx) for longer 15 pin female to 26 pin male cables or MC10(Lxxx) for 26 pin female to 26 pin male extensions cables here: Zaber Accessories.
- Note: 'xxx' denotes a length in cm
- Identify the cables intended for each axis using the matching configuration table in the Product Overview.
- If you have LSQ stages with dust covers, see LSQ Dust Cover Removal - access to the LSQ stage mounting holes will be required during gantry assembly.
Tips
- Whenever allowable in your application, mount the CGxxT cable guide terminations to provide the largest bend radius of the cable.

-

Push the AP200 plate as shown until the dowels on the bottom of the plate are both firmly in contact with the edge of the LSQ carriage - this provides Y-axis alignment. While holding the AP200 in place, firmly tighten the M6 fasteners using the 4 mm hex key.
Note: Tightening in several steps, while alternating screws diagonally, may help prevent the plate from moving during this step. -

Loosely mount AP200 part 2 on the X-axis 2 stage (connected to controller axis 2) using a 4 mm hex key and four of the provided M6 low profile screws.
This plate will be tightened and aligned later. -

See X-MCC Setup and Stage Connection if you have not already connected your stages.
Open Zaber Launcher. Confirm that three stages are detected and activated. -

Using Zaber Launcher, send a home command to each of the two X-axis stages to move them to their home positions.
-

In Zaber Launcher, use the Lockstep Configuration App to lock the motion of the two X-axis stages together.
-

Place the Y-axis stage on top of the two AP200 plates (or against the connected AB208 brackets, if applicable), with the connector end closest to the X-axis 1 stage (controller axis 1), on the larger of the two plates.
-

Using four of the M6 low profile screws (provided with the AP200), loosely assemble the Y-axis stage to the AP200 part 1 (the larger plate).
Loosely assembly the other end of the Y-axis stage to the AP200 part 2, also using four M6 low profile screws. -

With screws still loose, push the Y-axis stage firmly against the two dowels on the AP200 plate. With both dowels in contact, tighten the M6 screws between the AP200 part 1 (larger plate) and the Y-axis stage.
Leave the screws between the other AP200 plate and the Y-axis stage loose for now. -

To align the X-axis stages, move the X-axis 2 stage back and forth along its axis (loosen X-axis stage mounting screws if needed), until the AP200 part 2 (the smaller AP200 plate) can be aligned to the Y-axis stage with both dowels touching the edge simultaneously.
Do not move the X-axis carriages during this step - keep them at their home positions. Align the stages only by moving the entire stage. -

If there is not enough adjustment possible with moving only one X-axis stage, you may wish to loosen and move both X-axis stages along their axes.
Note: If you need to move the carriage to access mounting holes for the X-axis stages, use the manual control knob for either axis 1 or 2 on the controller. Both X-axis stages will move together, as they are connected in lockstep.
Return the stages to their home position before continuing with the AP200 assembly. -

When the X-axis stages are aligned well, tighten the four screws connecting the AP200 part 2 to the Y-axis stage, while ensuring both dowels remain in contact with the side of the Y-axis stage.
Leave the screws connecting the AP200 part 2 to the X-axis stage loose for now. -

Precautions
Important: Creating a loop in the cable of 150 to 200 mm (6-8 inches), between the top cable guide mount and the Y-axis stage, protects the cable and increases cycle lifetime.
Required Tools
- cable ties
- cable tie mounts
- scissors
Assembly
-

Use cable ties (provided in CGxxT kit) to loosely secure cables to the prongs on the CGxxT as shown, to restrict their motion.
-

Create the loop of cable using at least 150 to 200 mm (6-8 inches) of cable, for each cable as it exits the guide.
-

For cables to Z/theta and end effector devices, route the cable(s) beside the Y-axis stage and use an adhesive-backed cable tie mount (provided in the CGxxT kit) and a cable tie to hold the cable in place as shown.
-

To create the upper strain relief tighten two cable ties on the upper prongs of the CGxxT and the cable. The cable ties should be loose enough that you can move the cable though them fairly easily by hand, but tight enough to constrain the external cable jacket. This allows the internal cable wires to move through the strain relief to relieve bending stresses during motion.
-

The cable ties in this image have been overtightened and are pinching the cable jacket. Remove ties and start again if needed.
-

Adjust the cable position inside the guide.
1. The cable should be in the centre of the guide, not pulled tight against the inner radius or pushed against the outer radius of the bend.
2. Holding the cable gently on the controller side of the cable, move the stage along its entire range of travel several times and ensure the cable runs freely in the guide. -

Tighten the cable tie on the second CGxxT prongs to create the lower strain relief, matching the snugness of the first termination.
Trim the ends of the cable ties.
LSQ Dust Cover Removal

-

Remove the two M3 screws on the end of the LSQ device using a 2 mm hex key.
Slide the dust cover and spacer plate out from the end plate and through the carriage. The carriage top can remain in place or be removed.
To reinstall the dust cover, simply slide the cover back into place and replace/tighten the set screws and M3 screws.
Disassembly
To disassemble, follow the assembly procedures in reverse. Please keep the following guidelines in mind:
- Remove power before attempting to disassemble devices to prevent unexpected motion
- Retain fasteners for future use
- Keep cable guide assemblies intact
Operation
Setting Lockstep Tolerance
The lockstep tolerance limits the amount of twist between the two lockstepped stages as they travel. If the tolerance is exceeded, the devices will be brought to a stop, to prevent device damage from excessive twist. We recommend adjusting the default setting to larger values (up to the maximum safe values presented below for your specific configuration). Setting a larger tolerance reduces the risk of unexpected or jarring stops and should not affect the typical operating performance of the lockstepped stages.

Troubleshooting a Gantry product
The following sections contain tips for troubleshooting gantry behavior. Please also see the Device Product Manuals for individual stage behavior, indicator information, and additional troubleshooting.
Unexpected Behaviour
- An axis doesn't respond to a move command.
- The axis stage(s) may need to be homed before use. Send the home command, or the lockstep home command if the axis is in a lockstep group (X-axis).
- Ensure commands addressed to lockstep group stages (X-axis) are lockstep motion commands.
- A peripheral won’t move and move commands are rejected.
- The peripheral may have been unplugged and plugged back in to the wrong axis. Send the activate command the peripheral to continue using it.
- The device is moving on its own and running against the ends of travel.
- The position encoder has de-synchronized.
- Reset the device by power cycling it or sending the system reset (T:0) command, then re-initialize it with the home (T:1) command.
- The X-axis stages have stopped unexpectedly during a move.
- See warning flags for more information.
- A stage may have stalled. See X-MCC Troubleshooting.
- Lockstep twist tolerance may have been exceeded. Consider adjusting lockstep tolerance. See Operation section for maximum recommended settings.
- Lockstepped Stages Stuck or Not Moving Well
- Alignment may not be ideal or stages may have become twisted.
- Disable the lockstep group by sending lockstep setup disable. Typically this will look like 'lockstep 1 setup disable'.
- Perform alignment steps, homing, and lockstep setup again.
