Fourth session
The task for the 4th session was to produce the classical Turner’s Cube do demonstrate the ability of course participants to set up Lotta for automatic program execution including tool setup, workpiece preparatiuon and setup as well as program planning and entry into memory.
All of the other tasks were accomplished successfully except the actual entry and execution of the program. This was due to an unforeseen problem with Lotta’s display soft keys after the recent memory upgrade. Fortunately this was a known issue and an astute course participant was able to spot the fix in Internet. After quickly applying the fix (change parameter 9300 bit 7 from 0 to 1 - don’t ask) the soft keys again worked beautifully.
Unfortunately the hour was late already and we decided to assemble once more during next monday to finish the job. This will be done so all participants are invited to attend once more on Monday May 9.
P.S. After fixing the problem the course participants present wanted to test if the program can now be entered and run. So we did just that and it worked. To prove the program, one of the 6 sides of the Cube was milled and the result was as expected. We did note that one tool in the magazine was not properly calibrated which once more underlined that it is a really good idea to always run a new program in single block mode until you know for sure that it works as intended.
Next Monday we will go through the program once more when all are present and mill the remaining sides of the cube.
I will enter the program code here shortly for your information.
