Sagging Platform
As other people with a RapMan printer we also experienced problems with a sacking build platform. Supposedly this should increase the wobble in the xy-plane. We checked out some examples of people replacing the platform with a piece of 16mm MDF. Instead of this we have tried to use aluminum T-profiles bonded to the acrylic using strong adhesive glue.
This actually helped on the sacking platform and also helped a bit with reducing the wobble. Unfortunately there turned out to be a second factor influencing the sacking: our threaded rods are slightly bent. This forces the platform to twist and compress. So after running the printer for about 20 hours of prints the aluminum T-profiles started coming lose. So now we are still experiencing som sag and an increased wobble.
