Re: Davinci Jr and Mini Regional Tag Swap
One thin I can tell you, which you probably already know is. Pages 22 & 23 are the same on the two unused tags I have.
50 B1 E0 CE
52 E7 4F 76
Yes, that is values for 200m remaining length. All unused 200m rolls should have the same numbers in page 20 to 23.
The checksum for 300M in Page 21 is A8 81 36 54
Yes, that we can now calculate but we still do not know how to calculate page 22 and 23. Still the numbers for 299.722 is good enough. I guess we could even get closer to 300 than that with a few tries. I wonder what happens if you have a full 300m roll and start a print and then cancels the print while it is warming up the extruder? Or if that doesn't work you could cancel a print just as it starts and only have used less than a cm of filament.
Ok, I was able to get pages 22 and 23 before and after I initialized a print but before it actually printed.Attached are the results. Hope this helps.
Could we start a new thread for this work?
