All we use are accent inserters. Usually 3 on backup. Would take a ton of inserters to justify dedicating an entire machine bed to a quill
I'm not sure what you mean by this?
I've used the raster system for about 10 years, it's a solid system and definitely made us some money over the years.
About a year ago we decided to give the quill a shot, we regularly get orders for 200+
signs with braille and the braille was always a bottleneck, mostly because Noone wanted to insert the beads for 5+ hours a day.
The quill system is easily 5-10x faster than we were with our raster setup. We can now apply braille to 200 stairwell
signs in an afternoon, and if something messes up you just wipe the uncured resin off the
sign and try again, with the raster system, if a single hole isn't drilled deep enough, it's a major PITA to fix.
When we first got the quill, there were a few bugs that needed to be ironed out, but they do take feedback seriously and have worked out most of the issues.
I can't imagine going back to drilling holes and inserting beads!
