Helo Toblivar, did you manage to solve this? |
|
News? |
|
I'm also in a similar situation with the 250mc |
|
🙏🏼😅
Thanks.

So I've been poking at this for a few days now and I can't seem to make any headway. I've got a few dozen of the chips for the fortus 450 filament, so if anyone needs more scans let me know. Attached is an excel file containing two hex dumps from one filament canister. Here is the data I get about the filament from the printer itself: Name: "ASA_RED" So I got the hex dump from the canister, then unloaded some filament and got the hex dump again. Before unloading filament, Remaining Material = "3.95126" (cu.in) Looking at the hex dump, the only difference is in the first 12 bytes of data. It goes from: I'm not even trying to write to this EEPROM, I'm just trying to read the remaining material from the canister without putting the canister in the printer... Anyways, if anyone can crack this code that would be great, because I am at wit's end. |
|
fsabbatini89, Do you have any pictures of how you accessed the canister controller board?Or did you just use the diagnostic port on the back of the printer? |
|
Yikes, that's an expensive warranty to void! Have you tried sniffing the lines while the printer is checking the canister itself? I'll try getting a log of that tomorrow, and maybe see if I can get to that control board. When you say erasing the serial number of the cartridge from the PC resets the material, does that mean the material count isn't actually stored on the EEPROM? That's.... disheartening. Either way, keep me updated and I'll post some data when I get it! Enjoy the beer haha |
|
Oh that's clever! If/when you get a chance, can you post a trace of the full write command? Or just a full serial log between the pc and canister board? |
|
Awesome! I'm not even trying to get this EEPROM info to write to it - I just want to be able to read it. I have maybe 20 canisters that I have to log the remaining material in, and I want to just do it with a microcontroller without having to load the canister into the printer. Seeing the write message before it is encrypted will go a long way towards figuring it out. Plus if you share that string, then I don't have to break my printer getting to the serial traces 😜 |
|
So I'm getting some more data today. Here is a EEPROM dump, an oscilloscope sniff of the printer reading the EEPROM, and the information of the canister pulled from a TCP stream for full canister of yellow ASA. |
|
Here's the same set of files but after running through a load-unload cycle (uses roughly 0.5 cu.in. of material) EEPROM Dump - Yellow Load_Unload1.log |
|
And after another load-unload cycle EEPROM Dump - Yellow Load_Unload2.log |
|
Here's the OneWire Hex values of the Oscilloscope trace I'm going through and checking for common commands and stuff ASA Yellow Load_Unload1 - scope sniff.txt |
|
@fsabbatini89 Did you get a chance to get a log of the commands? |
|
So if I get access to the HDD, does anyone know what exactly I should be looking for? |
|
Do you remember what the baud rate of the RS422 is? |

Hello. any news about this project? I have Vantage Se and Fortus 450mc. Now i`m using raspberry to reflash eeproms on Vantage SE chips. If I can help with testing or smth else - here i am ) |

I think I am almost there. I would need some dumps of filled cartridges of
different materials if you have. Fortus 380 or 450

if you give me instructions how to make them - i`l send them to you. I have all kind of materials with support for 450mc except St130 and Antero. |

With the chip reader you have, with the raspberry just read and out it in a
file

Check this out |

I don't get it - this doesn't do anything to modify the EEPROM, right? It just erases the temporary value stored on the hard drive before the printer writes that value to the EEPROM? |
I would also appreciate an email. I have been toying with these new chips for a while and haven't really gotten anywhere. bill.the.williamson at gmail |

Hi everyone, sorry for the delay, I am on a trip right now and I will be
back by the end of next week. I will try to do my best to send you the
schematics and the soft. The cob is based on a dspic with 2 uarts (serial
ports) and a four rs485 driver chip from maxim. Are you able to buy this
stuff from mouser or digikey? Also the dsp only comes in surface mount
package soic for easy welding, are you able to send the pcb to a fab??

pickit 3/4, surface mount parts, and the rs4585 parts are not a problem. Looking forward to the schematic and source code. |
|
Same here. Can you send it to me too? tempmail348 at abwesend de |

The cron job has to be improved so it runs sporadically.. I just made a
script that runs only at startup and erases a file that holds the used
serial number of the cartridges but it can be run sporadically so you don’t
have to turn off and on the machine after changing spools with same number

@fsabbatini89 where are we at on this? Can you send the schematic and source? |

@spencermclegg I am so sorry, i completely forgot about this! |
|
@fsabbatini89 thank you! Do you have the source code for the firmware? |
|
Yes, i do. But first try that and let me know how it works.
One thing about this PCB: PLEASE! CONNECT IT THE RIGHT WAY, if you flip the
connectors your printer PCB will get fried as it uses 24vdc as power supply
and you will be connecting 24vdc where it should only be 5vdc.
I am telling you from experience :S

@fsabbatini89 Very interesting project. A slightly different approach than usual. By the way - what is the crystal resonator frequency you have used on your PCB? |
|
@Spreekom I am sorry, i forgot to add it on the eagle schematics as i used one i had in my box of junk haha. Tomorrow i will take a look at what the resonator says.. in my MPLAB project i have written #define SYS_FREQ 60825600LL With configuration bits HS PLL CLKDIVbits.PLLPRE = 0; so, following the formula from the manual FIN = Fosc / ((PLLDIV + 2) / ((PLLPRE + 2) * 2(PLLPOST + 1) )) = 60825600 / (22/4) = 11059200 = 11.0592MHz If i remember well, this is optimal frequency for the baudrate 115200 needed in this application (timing error = 0) Good luck! |
|
@fsabbatini89 I am interested in making this PCB but the file download is gone, any chance you could upload it again? If you are looking for help with this project I would be really interested in helping. I don't have that much experience but I will have access to a 380mc at my summer job and my boss will let me open it up. |
|
Hi! Yes no problem. I will upload it tomorrow, let me know when you build
it and test it in your company machine

@fsabbatini89 And also, you talked about a file that gets executed at startup that deletes a file that holds the amount of a wire in a used cartridge. Can you give more explanation? Can you, please, upload this file and how to use it? |
|
Hello everybody, We would like to offer compatible material for Fortus series 3d printers in EU. |
|
Yes my friend, Regarding the file that needs to be deleted i will let you know because i have some notes over here but i need to look them up :P Regards
|
|
Hi. |
I am so sorry! |
Hi Franco. |
|
Hi my friend!
Did the PCB work? If you just plug it should start working as expected.
Regarding the files, you just have to remove the HDd (make a clone from it,
I use clonezilla, just in case anything goes bad) and then just make a
startup script to remove those files I mentioned in the video.
And you are all set!

I have been printing and printing and printing without any issues 🙃
Hi Franco.
I've done with the PCB, but i can't deal with the printer filesystem. Iike
i see from your youtube video, i need to delete two files named
/mariner/config/system.dat and /etc/var/lib/dbus/xdh-cache. But I run into
issue how I can get access to the file system? Am I abble to get the SSH
access or I need to phisicaly remone HDD from printer, connect it to my
computer and copy there my own script to delete needed files? Maybe you can
provide the script and some simple instruction how i can run that script.

@fsabbatini89 did you ever create a fork for this? |

did you manage reseeting the eeprom of the ds2432? if yes can somone help with it? |
Привет . подскажи пожалуйста успешно ли показал себя метод на форус 450 мс |
and others
Has anyone had any luck reading/writing the 450mc chips? I've noticed they are slightly different in how they store everything (UID is 23-xxxxxxxx, no eeprom file but a "rw" file, "rw" file shows as all f values when viewed with xxd). I also understand that they use SHA-1 encryption on these.
If anyone can help point me in the right direction, I would appreciate any help available.
Thanks!
