Feeder Groups

If you feel changing components in the feeders tab with every job boring

Or

If your design has hundreds of discretes all in quantities of one’s or two, then a Blinds feeder is the most idle solution. A rejected blank PCB with alignment holes for dowel pins is an ingenious Blinds feeder hosting up to a dozen strip feeders. The PnP job is broken down to runs and each run is associated with its own Blinds Feeder. Without going into the boring details this option of saving and loading the feeders along with deleting all “placements” and “parts” other than the current run's clears clutter and makes placement more efficient to work on. These two scripts

• “1 Open Feeders.java”
• “2 Save Feeders.java” are for saving and opening your feeder groups. "Open Feeders.java" replaces current feeders. If you do not want this functionality, just comment deleteAllFeeders();
