We’ve had the Glue-Bot prototype up and running for a month or so now.

>Glue control is mostly 100%, though we are still having problems controlling the variable speed glue pump with M-code command inside the G-code programs. I want to be able to change the bead size at different points of application in any given program.

>We played around with several different nozzles, varying the orifice size and tip length until we had good control over the bead size.

>We had all kinds of problems with thin glue beads dancing all over and by luck we discovered that it was being caused by static charge on the foam parts. So we cannibalized an ionizer from an old machine that was taken out of service and that solved our problem.

>We’ve only been able to push the gantry robot to 150 ipm, but I’m pretty sure that we have some binding on the ball screws at the end of their range of motion that is responsible for that. When I design the full size production version, I’m likely going to switch over to rack and pinion drive.
