]]>- Optical sensor detects filament has finished.
- Continues print untill filament is pulled half way into the hotend. (This to give room for the new filament to be fed in)
- Pauses print, raises extruder 20mm.
- Sets hotend temp to 0
- Sounds buzzer.
- New filament is fed in
- Sets hotend temp to 220
- It extrudes 30mm of filament (which you have to manually clean away)
- Extruder drops 20mm, and resumes printing.
But yes, the crucial part would be the detection, which would cause the gcode to run.
About the DaVinci using the sensor during a print, when I was on firmware A, I tested it, by snipping the filament off during a print. It just kept on printing after the filament ran through. I havent tested it on current firmwares, though
]]>Lets say you have a 28 hour print going. And half way through, the filament snaps.
Once that last bit of filament feeds through the nozzle, there is no more coming through. that means the nozzle will keep being heated for 14 hours with nothing inside it. This will carbonize the traces of abs inside, and is very messy to clean up.
Couldnt something be implemented like this:
- Optical sensor detects filament has finished.
- Continues print untill filament is pulled half way into the hotend. (This to give room for the new filament to be fed in)
- Pauses print, raises extruder 20mm.
- Sets hotend temp to 0
- Sounds buzzer.
- New filament is fed in
- Sets hotend temp to 220
- It extrudes 30mm of filament (which you have to manually clean away)
- Extruder drops 20mm, and resumes printing.
I tried to load translucent filament with a white filament cartridge loaded and it would not do it. Found this forum post which helped. Thank you!
I got the materials to make a reset device but since da vinci does not have translucent filament does not seem to be an option if its checking for the color.
Anyone have any luck printing with translucent and making it work?
the problem is just the 'transparancy' not the color , the system just check if there is some filament. it didn't see your translucent filament as the light of the optical sensor pass thru it... i bet that if you put a black strip in front of the optical sensor, your filament will be ok.. end of story.. my 2 cents

]]>info..
This is from reversing both the FW and the Windows app.
00:xyzCode - 'Z'
01:material - 'A' for ABS
02-04:color
05-07:mdate - manufacture date ??
08-0b:total len
0c-0f:total len now, used to be remaining len in older fw
10-11:temp head
12-13:temp bed
14-15:mloc - manufacture location ??
16-17:dloc - distribution location ??
18-23:sn - serial number, zero padded for now
24-25: check digit - 0x0034 in LE format is the only one i've seen so farAlso it looks like since fw 1.1.I the printer remembers cartridges serial numbers and the corresponding smallest filament lengths. So every time you reset the filament counter you need to tweak the serial number as well, otherwise the printer will limit the filament output so your prints will break apart.
