Massive pucker problem in fill

[signman]

I'm stumped..doing the Kiwanis 'circle' logo, part of it is a 2" diameter filled circle about 1/2" wide-then .22 MicroTime CP
lettering on top of that. Double underlay under the circle, fill alone
is 8,000 stitches. I think 4 density, 15 pt stitch, 110 comp.
Looks great, other detail around and inside it are fine-until I add the lettering. Then it puckers up the circle about 1/4" and the lettering is off the fill.
Using 3 pieces of 2 oz. cutaway (middle piece is the 4x6 'hat' backing, nice and stiff) and solvy on top, Diport pique sport shirts.
Did over 10 sewouts to get this combination as the best I could do.
Lettering is up to 3.9 on density, 120 pull comp, min. width 10.
Been going around and around trying to get a nice sewout without the puckering and would live to get rid of the 'almost' cardboard stiff backing!

Oh, I did try shutting off the auto when it got to the lettering...it was running at 8, so I started inching it up-no higher than 10 or it would give false bobbin breaks, and at 10 was still puckering so I put it back on auto.
Have 34 of these to do in the morning so I'll see what thoughts anyone has before I fire it up tomorrow!
Thanks

If the stitch length is set to 15 pt in the fill, you could try setting it to 30 pt or higher and maybe the density in the micro times should closer to 5, my biggest mistake in the past has been setting the desity around 4 on small leters, now I get better results with the density around 5. It's worth a try changing the two things to see if it helps.
