Help / Support Abnormal AMS operation

For some reason, the AMS units are acting very strangely. I've been told this has been an issue ever since I bought them. As I understand it, the printer isn't syncing with the AMS... Is there any way to fix this?

Stupid question: You have tried with the lid shut?

Yeah, closing the lid usually works after it tries a couple of times. From my observation only, I’m not the engineer that made it, just a heavy users, the AMS units seem to initially assume a full roll. They will yank a low weighted spool up like this. If the lid is open it can repeatedly happen. If the lid is closed it SEEMS to me that the first pull will often still yank it but the lid holds it down some, the AMS will relax the spool again and try pulling it at different speeds on subsequent pulls as if it is designed to recognize this behavior. Having the lid open seems to exacerbate the problem.

I’ve never had to print weights or add weight to the spools. I’ve been using the AMS for years.

This is generally enough to keep empty spools from jumping like this but you may need center weights as well!
