Remote Motion Control Head for Digital Cinema

DSLR and Pro Video Cameras up to 12 pounds

VariZoom USA - Austin, TX –www.varizoom.com

Thanks for purchasing the CP Micro, our next-generation remote head. We worked long

and hard to make this the very best affordable motion control head on Earth, using trickle-

down performance and design cues from our bigger, more expensive heads, but also

taking novel approaches firmly anchored in proven mechanical design. No corners were

cut in the design - rather, we chose to omit expensive but non-essential features like slip

rings, standard lens control and exotic gearing elements, as well as scaling the whole thing

down to a more appropriate size for compact camera packages, thereby greatly reducing

the complexity and volume of the machining and material.

The tricky part was executing a cost-effective drive system worthy of the CP name while

shrinking its financial and mechanical dimensions to fit the market. The CP Micro is

indeed small . . . and lightweight . . . the manufacturing cost is another matter entirely.

Seeing no cheap way out, we bit the bullet and incorporated the best available

technology for the task, resulting in less profit margin for us and more awesomeness for

you. As our industry-renowned designer proudly noted, “This may be the best product I

have ever worked on.”

One of the coolest things about the CP Micro is that it works with all our other CP

controllers and control accessories, so whether you already own a CP/CPJR or you plan to

expand down the line, your investment is flexible. Anyway, enough with the blabbering

and on to the gear!

General Tips

1) If using a power source other than the one included, make sure to consult the

documentation and ask us before risking damage to the equipment. We do not

warranty against damage caused by incorrect power application.

2) The maximum recommended payload of 12 pounds is based on a balanced camera

package. Although the head will hold position with any camera package in that range, if

the load isn’t balanced it will cause the servo system to work constantly to hold position

and it can also affect the dynamics of the system unfavorably in both mechanical and

electronic terms. The horizontal and vertical balancing doesn’t have to be perfect, but it

should be close.

3) Don’t open the unit. There’s nothing to adjust and it’s not all that interesting. Opening

the enclosure may void your warranty.

4) The CPM isn’t waterproof. Treat it like any non-waterproof camera –with great care.

5) If your camera package is so long that it will strike the base of the CPM when pointing

straight up or down, you may need to purchase the VZCPM-HE3 extension. All of the

controllers have programmable motion limits except the VZJIBSTICKJR (incl. with

VZCPM-K5) –nevertheless, better safe than sorry!

Mounting the CPM

The CPM is available with either a Mitchell spud/nut or a 100mm ball/offset-plate/tie-down

knob system. The customer chooses the mount type when ordering the unit.

The CPM’s Mitchell spud/nut is a unique design optimized for jib use and allows cables to feed

directly through the pan axis while keeping the head directly above the mounting point. The

nut is a modified hand-friendly version of the castle nut that requires no wrench, and the CPM

base includes 2 thumbscrews that act as anti-spin keys when used on the VariZoom QuickJib or

SnapCrane series. If desired, a Mitchell wrench is available for additional tightening, as well as a

standard lower-profile castle nut. Also available is an optional anti-spin Mitchell key block for

using the CPM with traditional Mitchell plates.

The CPM’s 100mm ball is fairly standard other than the fact it includes an offset plate that

allows cables to directly feed through the pan axis. Included is an easy-to-tighten hand knob

with integrated socket cup washer for secure mounting to the 100mm bowl.

Cables and Power

The green 7-pin Lemo control cable connects the CPM head to your controller, while the power

supply plugs into the CPM head using a red 4-pin Lemo connector. The controller receives

power from the CPM head –it’s backfed through the green 7-pin Lemo cable. Extension cables

are available through VariZoom for both control and power.

With our oversized cable ports, you can also run video and audio cables through the tilt and pan

rotators to minimize tangling. Under the majority of real-world operations, cable twist

VariZoom USA - Austin, TX –www.varizoom.com

shouldn’t be a problem, but if you are using the head in such a way that continuous singl-

direction rotation is required, keep in mind that after several complete turns the cables may

twist up and require unwinding.

Please use only the power supply that comes with the CPM unless otherwise guided by a

VariZoom tech. The CPM can certainly be run from battery power, but it needs to be from a

regulated 24VDC output. If the voltage is too low, the head and/or controller will respond

sluggishly or simply not function, and if the voltage is too high –BOOM!!! (NOT covered by

warranty). We offer a cost effective 24VDC power converter (VZTOC-24VR) that will let you use

common 14.4VDC batteries or other ones up to a max of 36VDC, without any change in

performance, and we can provide cabling accessories and assistance, because you don’t want

to get creative and make power pinout mistakes or - BOOM!!! (you guessed, no warranty).

There are other battery solutions on the market, as well, but please check with us first!

Mounting/Balancing the Camera

With no power connected to the head, place the fully-dressed camera package on the CPM

platform and make a quick estimate of the front-to-back balancing point of the camera, aka the

center of gravity. You can quickly identify the center of gravity by balancing the camera on a

pen or pencil.

Also assess where the vertical center of gravity for the camera package is located. You’ll want to

adjust the camera platform so that the camera package’s vertical center of gravity is on the

center of rotation, aka the cable pass-thru port. The 3-arm knob can be loosened to adjust the

platform –once adjusted, tighten the 3-arm knob.

VariZoom USA - Austin, TX –www.varizoom.com

Go ahead and mount the camera with its center of gravity at the middle of the platform and

tighten the camera screw(s). Now rotate the camera so it points straight up or down. If your

camera/lens is long enough that you’re concerned about it striking the CPM base when tilting

straight up or down, you may either a) set soft limits on your controller (when available), or b)

purchase the VZCPM-HE3 head extension

If the platform stays in position, you should be balanced enough. If the platform drifts

downward, you need to adjust the platform position slightly, upward. Conversely, if the

platform drifts upward, you need to adjust the platform position slightly downward.

Although the CPM will hold position even if the camera isn’t balanced, but it will operate more

efficiently with a balanced load, and particularly when used on a jib a balanced camera leads to

smoother overall operation. The balance doesn’t have to be perfect, but it should be close.

Operating the CPM Head

First, make sure you disable OIS (optical image stabilization) if present on your camera/lens. OIS

can respond badly to the head’s motion, resulting in odd and unwanted visual effects, almost

like the image is drifting off slightly to the side. Mount your camera securely - with multiple

screws whenever possible. Also make sure the head is securely mounted and there is some

slack in the cabling so that the head’s servos aren’t fighting cable drag.

The controls at your disposal will depend on the controller model you purchased. As a baseline,

you will always have speed, direction, smoothing and deadband control. Refer to the controller

manual for further instruction on setup and options.

VariZoom USA - Austin, TX –www.varizoom.com

Here are a few universal rules of thumb:

1) When operating on a jib, balance is essential. Even though the head will hold position, if

the camera’s center of gravity isn’t right on the center of the tilt axis, you may feel some

swaying in the jib arm. Think of an ice skater spinning with one arm straight out and one

tucked in –he/she would go flying off to the side, slip and fall, no medal!

2) With a lighter jib, the same principle applies in regard to the pan action. Because the

CPM’s balance is offset to one side a bit, when panning at any significant speed, you

may feel the tug of offset rotational inertia. This is easily resolved by adding the optional

VZCPM-CW, a lateral counterweight that perfectly balances the rotational pan inertia of

the head. This counterweight could also prove useful if you’re operating on a

lightweight slider.

3) Be extremely careful and consult us before using your own power source –our warranty

does not cover damage cause by non-VariZoom power sources.

4) Make sure your camera package clears the base of the head when tilting –if it doesn’t,

set motion limits (when available), and/or add the VZCPM-HE3 extension. We can’t be

held responsible for damage caused by improper setup.

5) Practice your shots before rolling live to make sure you have the right speed, smoothing,

and deadband parameters to accomplish your shot. The CPM is a great head, but it’s

only as good as the operator!

Thanks, and enjoy!
