I have not forgotten about this project. Just have been busy with work and will be so at least until mid April. Have a conference to attend and as it usually goes things get busy.
On the more positive side - anti backlash nuts arrived today and I'm expecting to see the linear bearings to arrive as well within few weeks. The makerlab I was planning to use for laser cutting is a bit behind the schedule, as far as I'm aware, with getting back up and running after moving into a larger building but should also be fully functional soon.
