biglew Report post Posted August 31, 2013 So I bought a used tippmann boss...and I love it. A couple issues I have is that once in every stitching run it misses a stitch I am almost positive i am pulling down and up all the way. The second issue is that I do get marks from the presser foot no matter how light I adjust it? I am using the popular center foot. I am very thankful to all that take the time to answer and help Lewis Quote Share this post Link to post Share on other sites
PappyUSA Report post Posted August 31, 2013 The best place to start is to watch the Tippmann videos here: Don't mean to be short but these videos are excellent and will walk you through many problems. Check out all there videos, you can download them for future reference. Quote Share this post Link to post Share on other sites

PappyUSA Report post Posted August 31, 2013 (edited) Is it skipping on a stright stitch or curve or dose it matter. Here's my skipped stitch drill after I stop cussing. 1st: Check to see if the bobbin thread pulls evenly by hand with no jerking. If you have a trigger pull scale or fish scale get the pull between 12 to 16 oz. For a jumping off point. 2nd: Check timing and for bent needle. 3rd: With the handle held all the way up make sure the take up arm is also all the way up. 4th: Make sure your not force feeding the material.

mlapaglia Report post Posted August 31, 2013 +1 on the takeup arm adjustment. When mine skips a stitch Its always becasue I need to adjust the take up arm. Just be careful and do not adjust it too much. You get a ton of problems with tension issues when its set to far. Quote Share this post Link to post Share on other sites
