Reading F-Series chips? (F120, F270, F270, F370) #80

Tomblarom commented 4 years ago

My university got an Stratasys F370. Since I created this resetter for the Dimension Elite for my former school, I was curious, if these chips can also be manipulated. Couldn't find anything about them.

I've two EEPROMS. One totally empty 0% and one on 2%:

On the EEPROM is the following written:

40+      40+
1101     1101
917A3    914A3

Some people asked for this as well:

I found this EEPROM, which is pretty similar to which Stratasys uses: https://de.rs-online.com/web/p/eeproms/7327539/

Any luck? I have the same and wasn't able to access the chip using w1-gpio driver on a RPI.

But with some modifications, I can now access it. It says family 0C. Any ideas?

@luizrenault do how did you get to read the Eeprom, my raspberry refuses to recognize it. did you manage to get a dump of yours?

Same stuff. What modifications did you make?

Hi any news on this topic ?

Here somebody was looking for the same chip: https://www.reddit.com/r/AskElectronics/comments/oewa1l/help_identifying_ic_believe_to_be_some_kind_of_3/

There are chips which are very similar and have been suspectivly identified as DS2430 / DS2431: 40+ 1101 917A3 Stratasys F370 2D 1002 926B1 Discus Dental ZOOM 2600

It says family 0C

@luizrenault if you are correct, then it might be the same chip that was used in iButton 1996 devices: https://owfs.sourceforge.net/family.html Here is a disassembly of these devices: https://murdoch.is/projects/ibutton/

Any news? i tried and don't even can't even make the raspberry identified IC

@luizrenault can you please elaborate how you did it esthablish a connection? How does the wiring look like?

skylatian commented 4 months ago

@luizrenault, any word on what those "changes" were? My university would love to be able to use our own filament in these machines.

tkrsntr commented 2 months ago

@luizrenault, I'm also curious about how you read the chip using RPI, what modifications are made?
