Page 5: Chapter 1 Assembling The Track
Do not step over the track when the rig is switched on — walk around it instead. Overview Thank you for using Precision Track from Mark Roberts Motion Control (MRMC). The track is designed to help you achieve pixel-perfect repeatability of your camera moves by supplying smooth, rigid support when using large, heavy motion control robots such as the Milo, Titan, and Bolt over long distances. - Page 6 Precision Track Quick Start Guide to cope. Beyond this range you will need to use additional supports to keep the track flat and level. The track is not reversible due to the rack, which has teeth on one side. You must lay all sections the same way around. If...
- Page 7 Precision Track Quick Start Guide Each Precision track section has ten feet for supporting and levelling the track, and four anchor brackets for holding the track down if you are using a high-speed rig such as Bolt. Foot, which takes the...

Page 8: Laying The First Track Section
Precision Track Quick Start Guide Laying the first track section Lay the first track section on the ground, on its feet. If you will be using a fast rig such as Bolt and the floor already has anchor holes from a previous installation then you would obviously put the track anchor brackets over the existing holes. - Page 9 Precision Track Quick Start Guide Lower the six middle feet until they touch the ground (finger tight against the ground) and then tighten the lock nuts on them.

Page 10: Anchoring The Track
Precision Track Quick Start Guide Anchoring the track If you are using a fast rig such as Bolt On Track you must either hold the track down with weights (see page 30) or secure the track to the floor by using bolts or screws through the four track anchor brackets. - Page 11 Precision Track Quick Start Guide Put the drop-in anchor insert, threads upward, through the sleeve and into the hole in the concrete, all the way to the bottom. Insert the anchor spreader tool into the drop-in anchor insert. Hit the top of the anchor spreader...

Page 12: Laying Subsequent Track Sections
Precision Track Quick Start Guide Laying subsequent track sections If any of your track sections already have a rack installed, loosen the rack clips so you can temporarily slide the rack along the track and out of the Rack Clip way when you are joining the track sections. - Page 13 Precision Track Quick Start Guide Adjust the height of the new track section to match that of the previous section by adjusting the two corner feet nearest to the joint (one on each rail). Level the new track section with a spirit level by adjusting the two corner feet furthest from the joint (one on each rail).

Page 14: Mounting The Rack
Precision Track Quick Start Guide Mounting the rack If your track sections do not yet have the racks mounted on them, do this now for each track section as follows: 1.1 Loosen all the rack clips on the track section. - Page 15 Precision Track Quick Start Guide Rack matching block Rack mounting bracket Main rail joint Tighten all rack clips on the two adjoining sections of track. If you are using a high-speed rig such as Bolt, also secure the rack with an extra bolt through the rack at every mounting bracket. This is not usually necessary for slower standard rigs.

Page 16: Mounting The Bearing Rail Joints
Precision Track Quick Start Guide Mounting the bearing rail joints Hint Always mount and remove the track bearings with care. Try to keep them squared up and in-line with the bearing rail to avoid damaging them or loosing a bearing. - Page 17 Precision Track Quick Start Guide Align the bearing rail joint with the existing rail by sliding the track bearings partially over the joint at each end. Insert the bolts and tighten them. Slide the track bearings along the rail to the next joint and repeat steps 1 to 4 for all remaining joints.

Page 22: Removing The Trolley Wheels From Bolt On Track
Precision Track Quick Start Guide Removing the trolley wheels from Bolt On Track After mounting the rig on the track you can remove the two trolley wheel units that are on either side of the rig. With the base of the rig supported by the track, pivot the wheels away from the rig. - Page 23 Precision Track Quick Start Guide If you are going to store the wheels for weeks or months, release the wheel brakes so they don’t leave a dent in the wheel rubber.

Precision Track Quick Start Guide Mounting a Milo or Titan on the track bearings Stop at Rack the top Turret Base Ramp-up rail Pinch Rail wheel wheel Brakes Track motor gear Attach the pair of ramp-up rails to one end of the track, using three bolts on each rail. - Page 26 Precision Track Quick Start Guide Track bearings With the rig at the highest point on the ramp-up rails, carefully push the four track bearings onto the ends of the bearing rails (two on each rail) and into position under the four corners of the rig base.
- Page 27 Precision Track Quick Start Guide Track motor gear Teeth Pinch wheel mount point 10. Let off the brakes and push the rig further along the ramp, down the small slope, and the rest of the way onto the track. When you do this, make sure that each of the four track bearings fits into the recess at the corners of the rig.

Page 32: Mounting The Magnets
Precision Track Quick Start Guide Mounting the magnets Although you can mount the magnets for the Limit Switch and Datum Switch on the rack at any time, you ordinarily do this after mounting the rig on the track so that you can precisely adjust the height of the magnets relative to the magnet sensors on the pinch wheel on the underside of the rig. - Page 33 Precision Track Quick Start Guide the switch that is in the Limit magnet position, and the Datum cable to the switch that is in the Datum magnet position. Mount the two Limit Switch magnets (the two brackets that have the magnet in the same hole) onto the underside of the rack —...

Page 34: Mounting The Weight Wings And Mechanical Limits
Precision Track Quick Start Guide Mounting the weight wings and mechanical limits If you are using a fast rig such as Bolt On Track but anchoring the track into the floor is not feasible, you can alternatively attach optional weight wings to the ends of the track and hold the track down with weights. - Page 35 Precision Track Quick Start Guide Foot Weight wing Put the first weight wing into place on the end of the track, resting on the floor. Bolt the mechanical limit onto the end of the track, using two bolts in the upper holes. You might need to remove bolts from the track joint to make room for the bolts coming through from the mechanical limit side.
