Thanks for the reply Rich. Much appreciated. Yeah, all but one of them needed to be adjusted. All but one were coming down with the side of the print arm banging the top of the registration gate on one side. After loosening the bolts that hold the steel guide to the arms, lowering the guide into the bearings, and re-tightening the bolts that problem is fixed. The big concern I have right now is the pallet leveling....can only get one pallet leveled, but then the next print head won't be level with that pallet. I've tried using another print head to level to and can't get any of the pallets to level with it....they all need to be adjusted lower than they'll go. Is there some kind of adjustment that can be done to the side clamps or the side clamp mounting bar? I took all the pallets off and measured from the bottom of the print arm to the top of the pallet arm on all the arms to make sure the distance was the same on all the heads/arms...it is. So I feel like theres got to be something going on with the side clamp mounting bar. I took the side clamps off of the one head that I was able to get a pallet leveled to (lets call it head #1) and moved them to another head, then put the side clamps from that head onto head #1. Head #1 was still level. That tells me it isn't the side clamps themselves, but might be the mounting bar....or the heads themselves (hopefully not). Any help you can provide would be awesome. Can't wait to get this thing up and running!
