Using the Top Tension Pro on my Gammill Optimum
Q. I just received my Gammill Optimum longarm two days ago and am trying to get the TTP to work on my machine. I have followed the instructions and even watched the video! (Yay for the video!) I believe I have everything right but for some reason, I can't get a reading from the unit when it's installed on my intermittent tensioner. When I press the sensor disc between my finders, it registers a number, but not while it's on my machine. I am using Perma Core thread. What am I missing?
Please try out the following steps and let's see if we're able to get a proper reading.
- Make sure the wire leading to the sensor is underneath the arm of your longarm with the black side of the sensor facing the machine.
- With the tension discs on, slide the white washer with the lip facing away from the machine.
- Place the sensor with the black side touching the white washer.
- Place the silver retaining washer with the outward beveled edge touching the white side of the sensor.
- Place the spring, knurled washer, and knob. (Your machine will have two springs, one on the rotary tensioner and one on the intermittent tensioner. Please use the heavier/thicker spring on the intermittent tensioner.)
Here are a few number/measurements for threads when I'm quilting on our Gammill Vision. Please note that they won't be the same for you if we have different springs, thread brands,whether we're using a handy net or not, etc., but should be in ballpark range. (All threads are Superior Threads) I use So Fine! #50
in the bobbin exclusively.
Perma Core is a strong thread and you should be able to run it with a nice, tight tension and not have problems. I skip 1 of the 3 holes (on the 3 hole guide) on ALL threads that I use. I find that if I need to add or decrease tension, it's easier to control it with the intermittent tensioner than have it threaded through all 3 holes.
