Here is a Singer Futura hint from Singer I wanted to archive:
“Â The stitch count on the CE-100/200 is 8000 stitch per color block. Â If the block exceeds this limit the software splits the block automatically. Â The newer CE-150/250/350 will have a higher count. Â And the new FQ-4 will have even more memory. Â There are designs that are too large to send the entire DESIGN to the machine memory. Â In this case you would need to send block by block instead of the entire design at once.”
So if you have a stitch intensive block, send it color block by color block, instead of the total design at one time.
