Update on Draken improvement based on feedback from ultimate backers
We appreciate all the feedback from the ultimate backers and are working hard to assure best quality of Draken for the next batch. Here is a summary of recent progress and improvements:
1.) Z Axis Wobble
We have come up a solution for Z
axis wobble issue. A new two rail linear stage system
has been designed and is being manufactured.
See attached photo of the new system.
The stable two rail system is very stable without any wobble in our
All the second batch will be
shipped with the newly design linear stage. Any ultimate backers who experience
wobble issue can request to get a new linear stage (we will provide
instructions on self-installation).
We have designed a disk-shaped
stainless steel insert to be placed between the build plate and ball joint so
that the screw could be fully tightened (photo to be provided later).
3.) Resin tank spalling
The small cracks on resin tank
acrylic is found to be related to solvent in Makerjuice Resin. These cracks are cosmetic and don’t influence
the function of the tank. If you are
concerned about the cosmetic condition, please use other resins that don’t have
solvent such as B9 resin. We will test more resins and let everyone know which
resins don’t generate cracks on acrylic.
Meanwhile, we will find out more acrylic to see which one is resistant
We will use a new wiring system for
power inlets and board wiring. All wire ends will be covered by
plastic socket to avoid any exposure/short-circuit. Current users are suggested to use insulation tape to cover all power inlet sockets.
4.) Shipping schedule
There is at least 2-3 weeks delay in
shipping due to this change in linear stage.
This means no shipping at all in this 3 week time-frame, so please don’t
send us emails on checking shipping status during this period. Our next round of shipping is expected to
happen around end of Aug or early Sep.
5.) 3D Facture Resin
We have made a stable version of our
own resin and get it tested. Will be
able to provide samples soon and move to mass production.
6.) 3D Facture Software Release
We are developing a Java based
software that can cross different platforms. The progress is delayed due to the busy
hardware production and shipping recently. The overall framework is almost done
but need find tuning and testing. It
will be released for all backer once finalized.
