endless thread breaks on polo shirt

[SherriB]

I am freaking out I have a fairly complicated logo on left chest, it sewed out beautifully on sample materail, but I have a thread break every 100 stitches, it is a gildan 100 cotton pique, what am i doing wrong? needes?
head timing, backing, i have a tie limit and cant get through one... any suggestions woud be appreciated.
it is almost 10,000 stitches, was digitized by outside source.
Thanks Sherri

10k - what are the dimensions? What backing are you using? Double check your presser foot height and clean out the bobbin area (especially since you've had many breaks; a piece of thread could be caught and cause havoc). Did you run your sample on the same type of material? Call me if you want.

Another cause for the thread breaks might be the density is too full. If you can click on a fill section or a column and make the density higher. This will put less stitches in the section so they won't hit each other. You could make the density a larger number on top and make the number on the underlay lower. Example: fill might go to a five or six and the underlay would be 20 or 15. That will give you coverage but make the overall effect softer. I am in Chandler and you can also call me. 480-216-3163.

Sherri,
You haven't given us enough information to be able to help. I would suggest running the Melco Ampass design. Use a 44cm X 30cm hoop. Find the design in C drive--Program Files--Melco Embroidery Systems---Amaya---Test Designs---Ampass

Load this design and run it by assigning colors 1 thru 16. Run at 1200 spm and make sure the presser foot is down. Use two layers of medium to heavy weight backing and hoop tightly so the backing is snug in the hoop....

This will tell you if the machine is the problem or if the design you are dealing with is the problem.

thanks all, I am so new to this, most all is foreign, Three of the six colors run fine, but I feel the wording is too dense, it is very tint and thin. also what did sample on is not same material, so I understand why it looks great, the sample is on a apron type material. what needle would you guys recommend, I have 80/12 BP right now.

If 3 colors are acting up, you can test the needles by moving the design to different needles. So if you are using colors 1,2,3,4,5,6 now, move it to 7,8,9,10,11,12 to test it. I use 75/11 ballpoint needles on most everything with a few exceptions like caps would get sharp needles and other strong or think materials. It could also be the density of the digitizing doing it too. If you want to email me the file, I can do a test run of it tonight when I get home.

Sherri-I am familiar with the Gildan polos-great shirts, but not very dense because of the price point. If it is one of the pique knits, you may need a solvy layer on TOP to hold the stitches up, and also likely you may need 2 sheets of 3 oz. soft cutaway for backing-to hold the shirt fabric in place and give the thread something to bite into. The thinner the material-the tighter that thread is going to get as it sews...and that turns into thread breaks.
More details will help!

Sherri,
Check the needle rotation. Make sure the front of the needle is forward on all needles and that the needle is inserted all the way up into the needle clamp.
