I let it continue to run without the back-to-back CAL and saw no problems. I have gone ahead and made these changes to my software. To be clear, I have no plans to write an interface for your scope, but at least now I have what I consider a good platform to build on if I need it.
This will not come out before your review is published. You should review the product as it exists now. But this is just to say that we understand your point, and want to do better.
For the review, I had planned to only show your software. So these details about your choice for the serial interface are not relative. I have thought about doing a segment on my LabView source code. With it being pretty much a dead end tool now with their extortion tactics and subscription model there may not be any value in including it. Someone wrote me the other day who had attempting to reinstall their older version of LabView and claimed they could not get their license to authenticate. That's twice now I have heard that. One was from a university.
Some parts of my review that I had already recorded will need to be updated. For example I had done a tear down at the time I reprogrammed the unit. Because I had not removed the PCB from the case, you only got to see the top side. When I reworked the board, I did not record anything. The focus wasn't about making a video but rather attempting to solve the random problems I was seeing. Working with these tiny parts gets more difficult as I age and the risk of damaging the unit because of not being focused on the task at hand was too great. Now, with the new case coming, I will redo this section of the review. Pretty sure I can swap out the case on video and not damage the scope.
Other parts of the video where I was limited by your software may also change.
Honestly, had I just reviewed the scope the way it stood when it arrived, it wouldn't have presented itself well. Over the last month, things have really started to shape up. I would like that power user mode but can certainly proceed without it.
Making reviews isn't really something I am good at to start with. Compound that with the moving target you have provided, it adds an extra layer of difficulty. If it were a simple unbox, look at the parts supplied, five stars... Maybe include some music and talk about what an expert I am, then sure, I can have it done today. I suggest you be patient.
Thanks again for the careful testing you've done. We haven't received any other reports of hardware issues outside of the the ones you've mentioned. For now, we are confident that the "growing pains" have been resolved, and the hardware is stable.
I too am confident in the the hardware design. Your build quality is still a question as I have not seen what your production process looks like. The firmware/software seems a bit lacking but as you have said, you plan to continue to develop it. Potential customers just need to be aware that any limitations I may show during the review could possibly be addressed in the the future. Of course, no guarantees.
As a precaution, we have added a note about repeated CAL commands in the next manual revision. The official software happens to be set up in a way that never sends back-to-back calibrations, and so avoids the issue. Thanks for bringing it to our attention.
If you can't replicate it, and nothing in your design appears to match up with the symptoms I have described, I really don't know what else you can do at this point.
