Vacation time and 3D printing

After some days of vacation we have continued the robot testing.

Last days we have been working on the 3D Printing Toolhead. We did several printing tests with good results and we found the speed limits of the machine which are aprox. 3500 mm/min (when 3D printing)

Also we improved the server side software. We added functionality to control the 3D printing extruder and the hot-end temperature.

We also developed a firmware algorithm to test how efficient is the auto-levelling algorithm. We had some doubts about if really the algorithm worked fine but they were unfounded because it does and the platform is always levelled with a precision of less than 0.01 mm.

We must do more testing with the Laser Toolhead. Before vacation we lost a lot of time trying to focus the laser with the new glass. Finally we saw that we did a mistake choosing the glass thickness. When we built MKI we used a glass 1.5mm thick but we built the new one with a 2mm glass so we had to cut another platform on a 1.5mm glass and test again. We hope we can do it next week after finish 3D Printing Toolhead testing.

So, more testing on September. We hope to finish it by October.
