The key issues for Schiffli digitizers are as follows:
Schiffli machines are large, the frame has a mass, which in turn implies a speed limit on their operations.
Lacework is soft, the thread tension has to be low. This is controlled by speed limits on older machines, thread ‘pushing’ techniques on newer machines.
Over 1000 needles can be engaged at a time. This creates a pulling force for larger stitches or movements which has implications for tension and speed limit control.
Mechanical Schiffli machines have no memory – the digitizer must think ahead to control speed and tension.
There are no trimmers on older machines – the digitizer must take account of thread hanging off the fabric. The main rule is that stitching starts from the top, gradually moving down the design so that hanging threads are not over-stitched.
Needles cannot generally be engaged automatically so color changes are time-consuming and typically avoided.
When you activate ES Schiffli, the default design template may or may not be automatically replaced by a Schiffli-specific one. For Schiffli work, you need to use this template. The Schiffli template sets the machine format to Schiffli and also turns off all the automatic connector settings.
Note: The design template does not change the stitch settings as you will want to set your own values. See Setting up Schiffli templates for details.
