Upgraded my printrbot GO x-axis also from Wantai to Kysan with smaller Al pulley and 3dp Aftermarket damper. Time to print some stuff. #3dprinting
Supplier links?
I got these Kysans from Printrbot. They actually sent them with the initial kit by mistake.
What about the Dampers?
3dp Aftermarket is the name.
Aha! ok… they’re not the sort of dampers I was expecting. This was why I was confused. No problem. 
Yes, they’re pretty low-tech. I don’t really have room on the Y-axis in particular for anything fancy.
Think I might get some cork like that and cut some up on the @Connected_Community laser cutter.
They work.
