A good solution with some deficits of the implementation. Positive: - Easy, intuitive interface that can be discovered and understood without a manual. - Fast and rather precise control of temperatures due to an option to calibrate individual tips. - Adjustment of PID levels of the controller helps to avoid significant temperatures drop during soldering of large parts. Negative: - The aluminium metal case is not grounded! Danger of an electric shock! It can be easily solved by installation of a dedicated cable inside of the case. - A flimsy mounting of the main controller with the LED panel. The PCB of the controller is fixed on both edges, but is not parallel to the front and LED panel is positioned not properly. This could be easily adjusted by placing an additional washer on one side. - Supports only linear tip profile correction that is not sufficient for tips with a non-linear profile. Calibration of the tips will be performed by 3 points. However the resulted correction is just linear and is the same for all 3 points. So, if you have a tip with a non-linear profile, then you cannot properly adjust temperatures on all 3 points with a such correction. You need to sacrifice one edge point for the two other. Or, alternatively, if you need to have a proper middle, then you should to leave deviating edge points. - The functionality of the firmware v3.1s is not matching the hardware. In the menu you can find some additional options, e.g. for a vacuum pump, but the installed controller was not designed for these options. The version of the hardware will be indicated as 3.1, but in fact the PCB looks very similar to version 2.0. The respective extensions of the PCB layout that you may find on the version 2.1 are not there. - The firmware has a bug in the calibration. After calibration of a of BCM2 tip if you power on the station then the menu will be closed with a password. You need to enter a password "5555" and reset the station to get it back to the normal work.
