full-roll calibration #7

Closed mark-hahn closed 5 years ago

mark-hahn commented 5 years ago

I have found that manufacturers tend to put exactly 1 Kg of filament on a roll. I assume this is because their equipment measures accurately. And if they put too much they lose money and if they put too little they will get complaints.

I suggest a calibration option that is more precise than guessing the spool weight. When you put a full roll on, you click one button and it stores the full weight. Then it always knows how much is left of the 1 Kg. This option would replace both the tare and the spool weight guess. And the calibration would happen on every new roll.

For extra credit you keep a database of partial weights of rolls not being used.

I'll close this since there is no interest.

BTW, I'm using this technique, sort of. When I put a new roll on and I don't know the spool weight I adjust the spool weight setting until the net weight shows 1Kg.
