After replacing the standard hot-end with an Olsson-Block, my Ultimaker² is again up and running. The new system allows switching between nozzles of different diameters in less than a minute. I’ll run a few tests with different nozzles within the next few weeks. Right now, I’ll try to keep up with printing the current orders.
The high number of 3D-prints I did recently, left their traces on the printer nozzle. Since I have to service the print head, I go for a new hot-end that allows me to swap nozzle tips. This allows me to use different diameters to gain even better printing speed and/or quality.
I can’t use the printer until the service is finished. Until then, most of the 3D-printed parts presented on this site (like the battery dummies or LED rings) are available in limited quantities only.
I received the first batch of filter holders today. Shipping starts in sequence of order (resp. payment). More items will be available during the next weeks. Don’t panic, there’s enough here for everyone ;-)
