 #### Day 3
+
+We started the day 3 thinking we would be able to immediately start the calibration.
+But in reality, the laser tube and the mirror installtion is one of the last operations, requiring a lot of different checks beforehand.
+
+We spent good part of the morning (till 12:00 circa), testing all the relative subsystems:
+
+- AC connections
+- fuse and emergency button
+- DC connections
+- logic connections
+- stepper drivers
+- stepper motors
+- window sensors
+- water system and chiller (the water flow sensor is always leaking)
+- radial fan
+- air assist compressor
+- filter
+
+Then, just after lunchtime, we did start the calibration process.
+
+The machine belonging to Hofalab had a straightforward calibration process, because the frame was built carefully, spending a lot of time in aligning things. At the end of the Hofalab machine had almost perfect calibration in all the 4 corners. We anyway decided not to cut to be fair to the other group and also because we needed to end the day earlier for moving the machines to the room in campus nord.
+
+The machine from Regenholz had a slightly more troublesome calibration, with some confusion about how to move the mirrors and the tube to center the laser beam to the laser head. The laser tube was moved to an extreme position, not allowing anymore any further calibration. The local team and my team did not know that the 2nd mirror can be moved horizontally in 2 dimensions, thinking there was something else wrong in the machine. After letting them know the problem was solved, and by the end of the day the managed to have an almost centered laser beam into the laser head.
+
+The day ended with huge efforts to move from one room to another, with issues about parking, traffic, and heavy and late transportation to the new room. In general, we should always avoid any moving durign such workshops, especially to avoid losing the laser calibration because of it.
+
 #### Day 4
+
+The day started with checking again the calibration from the moving of yesterday. Both machine kept most of the calibration done, allowing to quickly start to test the machine motion and the firmware settings. The machine from Regenholz completed the calibration successfully during the morning, while the machine from Hofalab had the first successfull cut.
+
+I had to go with Lennart to visit the Fab City House location, and left the workshop to my team mates, that used this time to show how to use the machine to the people. Just before leaving also the machine from Regenholz was able to cut sucessfully the first pieces.
+
+The day concluded with both machines being used to produce some predefined demos (eg logo), and with some quickly made designs, like the Fab City Hamburg logo.
+
+We went all together to dinner after the workshop.
+
 #### Day 5
 
+During this day we sorted out the last questions and worksflows on how to use the machines. Both machines were running fine and many new designs have been cut with it. The workshop participants acquired much more knowledge about how to use the machines. 
+
 ### Participants
 
+In total we had 19 participants registered, but not all them came.
+
+Here the original list of participants registered, in bold who came at the end:
+
+- **JC Mariscal**
+- **Sasha Kruse**
+- Luisa Lange
+- Svenja Zadow
+- **Pieter Hijma**
+- **Mohammed Omer**
+- **Oskar Lidtke**
+- **Piet Jarmatz**

+- **Florian Hanebeck**
+- **Henner Henkel**
+- jonas
+- Merten
+- **Sebastian Müller**
+- **Werner Jarmatz**
+- Hauke Preuß

+
 ### Final results
 
+The final results were 2 fully working Fabulaser Mini machines.
+
+The machines were working already 1 day before the end of the workshop, leaving the participants time to learn how to use the machine.
+
+Overall it was a great success without severe issues, but only some minor mistakes in production and in the manual.
