Material not identifiable

[256FF]

I dumped a lot of chips of my HP Designjet (aka uprint) and can read the values. But Material is shown "unknown (4095 - 0xfff)". Can anyone please help me to add my Material to the material.py so that I can create a refill file from zero.

Another problem is, when I use the "REFILL" command for the stratasys-cartrige.py the material will be changed and I don't know why.

Attached there are these files: 400ccm.bin - Dump of the original EEPROM with 24.xx cuin full.bin - Dump of the original EEPROM with 100% refill400.bin - created with the refill-command from the 400ccm file refillfull.bin - created with the refill-command from the 100% file

the name showing for the HP ABS Ivory in CatalystEX is "P430L_IVR" so, I suggest adding a new line based on the P430_IVR, like: id_to_name[0xXX] = "P430L_IVR"

The only thing needed is the hex code for this one. Basically, we just need to find it in the decrypted dump. (I didn't check yet on how this tool work, so I maybe totally wrong ^^)

And where can this be found?

I think using the hex code stratasys-cli is giving could be good. As seen in issue #21 , 0xFFF (material??) and 0x1FF (support??) I'll try python on my Pi this evening on my HP material dump if I have the time. I think this could solve the first problem.

For the second issue, I supposed (I didn't even try nor seen the code yet) this is related to the unknown material not supported for refill? Maybe @bvanheu can help us on this ?

Hi,

It's not the first time I hear about this material id (0xfff) but I'm not sure if it's a valid material? Maybe it's a sentinel to let the printer know this is a special kind of material and it should be found elsewhere in the EEPROM dump?

If you are sure it's the correct material id, then yes you simply need to add a line into this: https://github.com/bvanheu/stratasys/blob/master/stratasys/material.py

id_to_name[0x387] = "ULT_S_2"
id_to_name[0xfff] = "MATERIAL_NAME"

Afaik adding 0xfff does not work. I even tried it. At the next time reading the dump with this informationaterial is show as unknown 0xffe

Late, for me too late there is a solution.

For the HP machine silvood found the material codes:

new Material() {Id=0xd3,Name="SR30L"},
new Material() {Id=0xdd,Name="P430L_IVR"},
