My RA motor has failed, and I need to restore tracking immediately!

Another innovative feature of the Mach1GTO is that the declination and right ascension servo motor/gearboxes are

interchangeable. In the extremely rare chance that your RA drive would fail in the field (at a star party in the middle of

nowhere under perfect skies according to Murphy’s Law), you can simply swap the two motor/gearboxes and still have the

mount’s tracking ability. Please note that while the declination motor/gearbox box is on the RA axis, you may have a little

more periodic error than you are used to, since the fine tuning was done on the RA’s original motor/gearbox. Also, since you

will be using a different worm gear, your PEM will be different. For imaging, you may need to retrain your PEM. For visual

observing, simply turn PEM off while using the declination motor/gearbox on the RA axis.

To remove a motor/gearbox, first separate the two axes, and then remove the four small screws on the box that hold the

cover with the servo cable connector, and pull the cover off to the side. Its wires will remain attached to the motor. Next,

carefully unscrew the two shoulder bolts that hold the motor/gearbox to the axis. Note that there is a spring exerting pressure

against these two shoulder bolts, and take note of the spring’s position against the shoulder bolts. When they come loose,

the spring will push them over. That is fine; don’t try to completely remove the bolts. The motor/gearbox will now separate

from the axis. To re-install a motor/gearbox, carefully set the box into position making sure that the worm gear settles into

the teeth of the worm wheel. Put the two shoulder bolts in place, but only snug down at this point. Make sure that the spring

is properly positioned below the ridge in each shoulder bolt. Gently rock the motor/gearbox back and forth, and then center

the box in its range of motion. Now fully tighten the shoulder bolts, starting with the bolt on the left. Finally, replace the cover

with the four screws and you’re ready to go.

There is a detailed instruction sheet entitled “Remeshing the Worm Gear and Wheel” at the end of this manual that will help

you get your gear mesh just right. As more detailed information from real life experience becomes available, it will be posted

in the Technical Support Section of our website.

My GTOCP3 Control Box does not appear to be working properly. Can I use the control box from my other

Astro-Physics mount with my Mach1GTO?

The answer depends on which model your other Astro-Physics mount is. The GTOCP3 from your Mach1GTO can be

interchanged with the GTOCP2 or GTOCP3 from a 900GTO or a 1200GTO mount. The interchange works in either

direction: the Mach1GTO can use the 900GTO or 1200GTO’s control box, and the 900GTO or 1200GTO can use the

GTOCP3 from the Mach1GTO.

A GTOCP1 cannot be used as it does not have the correct servo cable connection. DO NOT use the control box from a

400GTO, a 600EGTO, a 3600GTO or from a mount purchased from an OEM partner that uses our GTO system.

As a final note, if you “borrow” another control box for your mount, you must disable the PEM since the PE curve in the

borrowed box will be for a different mount. You can always record a new PEM data set if you wish, and there is no reason to

preserve the PEM data set in the borrowed box since it will no longer be valid. Any time that you use a different control box

on a mount, the PEM data becomes out of phase and will need to be redone. This applies to both the borrowing mount and

the lending mount. It is something to consider before trading control boxes, especially if you have achieved a particularly

good PEM result with the mount that is to be the “lender.”

I am concerned about achieving good balance in the system. My clutches don’t seem to loosen up the

axes as much as my 900 or 1200 mount’s clutches when I loosen the knobs. Is this correct?

The Mach1GTO uses a different clutch system, and it also uses a different bearing system for the free rotation of the axes.

It will feel stiffer than the 900 or 1200 series mounts, even with the clutches fully disengaged.

You should also be aware that the clutch knobs on the Mach1GTO have spring loaded tips that may still be applying

pressure to the clutches, even though the clutch knobs feel loose. Back the clutch knobs off by at least three full turns to

fully disengage the clutches. Then swing the axis back and forth a time or two before trying to actually measure and adjust

the balance.

There is really no need to balance the Mach1GTO to any high degree. The motors are quite strong and can handle well over

a pound of imbalance in the load. When moving either axis back and forth by hand, even with the clutches not fully

loosened, it is quite easy to feel as little as a few ounces of difference.

If you really need to balance for some reason, you can use a small fisherman’s scale to pull the axis in one direction, and

then the other. When the pull is equal, the axis is basically balanced. Another method is to use an ammeter to measure the

current draw. Use the opposing direction buttons at 64x and observe the current being drawn. A balanced load will result in

equal current draw in either direction for each axis.

The declination axis does not appear to be moving properly. How can I check it?

Please refer to the appendix for the instruction sheet: “Characterizing the Dec Axis Motions,” which explains how to use

Maxim DL software to characterize your mount’s performance.
