I just received my unit and have it mostly assembled.
The fit is very good except for the front panel: the PCB appears to be forced away from the front panel on the right side (where the two F1 boards plugin) - this causes the upper case to not align with the screw holes on the two F1 boards and the mounting screw for the front right foot pushes up against the front panel PCB.
I'm not really sure that I understand your problem. Yes, it's true that right side of the PCB is slightly higher when mounted but that shouldn't make any problem to plug in both Power modules in place.

I have same problem. It is not possible to align the screw holes on the power board heatsinks with the holes in the bottom case (perhaps with a lot of force applied to the front panel pcb???). It appears that this is due to the front panel pcb pushing the power boards away from the front panel?
Hi all,
I just finished assembling the PSU and after checking all connections carefully, I powered it up. As it seems one power board (03/2017 r5B12) isn't working as it should: even if every setting seems to happen, I don't get any power on its output. When I swap the boards the error moves to the channel where the defective power board was inserted, while everything else works fine on the other channel.
A fast comparison between both boards didn't show any difference, thus my post here. Is there a (n easy) way to check the board while not inserted into the casing?
Any help would be appreciated!

Please let me know if you can measure distance of 42.5 mm between top or bottom plate front edge and lower two holes for Power board heatsinks fixing.
I'm having trouble calibrating my EEZ PSU.
I assembled it from a complete kit and it seems to work correctly, but I cannot complete the calibration process on either channel. When I get to the mid current setting, it will not accept the number that I enter - it always gives a "Value out of range" error. I have tried entering the value in amps ("2.48A") or milliamps ("2480mA") and also tried some other random values but it always gives that error.
Board version R5B12
Firmware version 1.0 & 1.01 (I tried both)
I saw a similar problem reported on GitHub but according to that, the problem should have been fixed for version R5B12 of the power boards.
Has anyone else seen this problem with the shipping version of the kit and firmware 1.01?
Is there a later firmware release I should be using? (1.01 looks like the latest on GitHub.)
Should I try hacking the firmware to just accept the value that I enter? Or could that lead to problems with current regulation?

Did you set a current limit greater than zero? On my unit, one channel will output a voltage with the current limit set to zero and the other will not.
If I understand correctly power-up selftest is passed but after that when you set voltage and current that are non-zero value and enable channel output you cannot measure set voltage?
Please open a new ticket on GitHub for this issue. Establish serial (via USB) connection (e.g. Arduino IDE serial monitor or any serial console application) and copy debug trace text that will appear during calibration process. Before start calibration send *IDN? just to be sure that serial communication is established.

It looks like it - Another USB cable, direct in the native port solved that issue..
Should i order a new USB isolator and try to replace it?
