How to Use This Blog

Since we have lots and lots of videos here, you will need to know the best way of finding what you are looking for. Each post has the video(s) of the topic it is about. Sometimes there will be more than one video that is a continuation of the previous one. These videos will be posted together within the same post. To find what you are looking for, either use the search box or the list of categories posted in the right column.

The IQ system is constantly evolving, so please keep in mind that some of the older videos may show features that have been replaced by newer ones, or buttons that have changed position or names. However, the videos have not been removed because the methods demonstrated are still valid.

Adjusting the IQ motor brackets

Another great video by Patty Butcher, demonstrating how to adjust the iQ motors. Pay attention to how much to loosen and then tighten - as Patty says, only teeny tiny turns. Never, ever loosen them a lot - it will be so much harder to get the correct adjustment.
NOTE: Patty is working on an APQS machine. On my Gammill I couldn't use the carpenter's square as Patty does to check that her motor is straight - I had to hold a straight edge and compare it to a straight edge on my track. I've shown that in another post.

Removing IQ Motors for Service

This video by Patty Butcher demonstrates how to remove the IQ motors from the adjusting brackets without altering the adjusting brackets in any way. You will want to do this whenever you are required to remove the motors, for servicing, changing drive wheels, etc. The process is the same no matter the machine make, model or vintage and older style motors.

How to check that your motors are running straight.

This document shows how to check whether your motors need straightening or not. If they are only slightly crooked, this method will work. If they are grossly out of alignment, you will need to adjust the brackets screws, which is shown in another post.

The photos show only the X motor (the one that runs the length of the table) on my Gammill Premier. Check the Y motor in the same way. The photos show an original motor with the white gears, and a supermotor with the clear belt. Your motor may look slightly different but the mounting block will be the same. It is important to place the straight edge against the mounting block and not the motor cover.

Take the cover off the motor and place a straight edge against the mounting block that has the two set screws, as shown in the photos.

Look along the length of the straight edge and compare it to the straight edge of the track - it should be parallel. 
If your straight edge looks like the first picture below and is tilting downwards (probably not as much as this), then give the motor a sharp tap on the right side of the motor with your fist, as shown in the second photo.

Check for straight again. 

If your straight edge is tilted up like this picture, give the motor a sharp tap on the left. 

Check for straight again. This is usually enough to fix a slightly out of straight motor. 

NOTE: if your motors move too easily, then the bracket screws are probably loose and need tightening. 

If your motor is straight, next check that the sensor wheel is straight as shown below. 
Also move your machine by hand and watch the sensor wheel - if it wobbles or isn't running straight, check the very tiny set screw that holds it in place. The wheel may have come loose.
