Tear down of Cubify cube 3 3D Printer + convert to RepRap

@Geezer70
Thx for the compliment. Im trying my best to get this going. But this is teamwork, I need help here.

P.S. I just zeroed my Cartridge

Just ask.... What do you need?

 

Are there the memory locations for the data or is this just where they are declared?

 

I just zeroed out this whole code

 

@Tom Dirriwachter

I cant find the strings in that location...

 

That would be V1.07, I guess.

But it does have an Engineering mode... that is interesting.

 

Meaning?

 

yes that true. Should I flash 1.07...
I do have so many things to try. I am on 1.14 right now. If someone fins something in IDA , i can try it.
My cartridge is at 0% right now. I need to find the routine in which the cartridges is checked, read, and blocked if it is at 0%

 

I did write 00 as opcode (nop)

 

Definitely stick to 1.14b.

The 0 percent chip should be recoverable.

Can you find the routine that checks the cartridge?
You might be able to reroute and empty cartridge to the full cartridge routine.
I think Geezer pointed to it in v1.10.

If a cartridge is considered full, the FW may just ignore the current remaining value and replace it with whatever the current print requires. If this works as I suspect it does, empty chips will be "refilled".

Also be aware that new cartridge installs can send the printer into the calibration routine that is difficult to get out of.

 

Looking into the config bits, which are the penultimate line in the hex file with debug off:
:102FF000FFFFFF3CD979F8FF5B0DEDFFF7FFFF7F87
And ON with checksum updated:
:102FF000FFFFFF3CD979F8FF5B0DEDFFF7FFFF6F97
Have I git this right, or am I shooting blind?

 

Actually debuging is working with the code you posted before.

 

Ok, so I just turned on code protect.

 

could be

 

Ok some update for you all.

This is the write routine when you start a print. I did succeed in stopping the wri[ing process. But cartridge removed error is popping up after 30 seconds.

 

There is likely a confirm step that it has written successfully.

 

Here is a goody for all of you.

 

You tease!

 

Testing right now, it is working on both cartridge sites.

 

What is the idea behind your mod?

 

BLAHH to Spiderman, You're my new Hero! CheCheMan. High-fives

 

@Tom Dirriwachter

Sorry. What do you mean?
I did modify the firmware so it does not write the Cartridges. So it will stay at the percentage it is on.
You can feed your own filament now without worrying about the chip itself.

High Five Accepted

 

P.S:
This patch is also working on the Cubepro V2.00 Firmware. I will be testing with some of my Beta Testers.

Release will be end of this week for both printers if everything works like it should.
Will release for both the Cube 3 and the Cubepro.

 

Willing to accept donations

 

Did you figure out why it was resetting at 30 seconds?

I'm new to this thread, having followed a link posted on another forum. As a (too) long time owner of a Cube3, I'm encouraged by what I've read thus far, all 17 pages of posts. The topic heading refers to the phrase "convert to reprap." Does this mean disassembly of the housing and replacement of components, or, as I am hoping, a firmware modification?

If the latter, and eychei is able to provide for novice "hackers" such as myself, I'll certainly contribute to his funding.

 

Yes i did find a routine in which it was reading the cartridge and then going to the write process. The read routine did have some jumps and calls so i patched what i could find.
But now i am down to 2 patches.

 

I will start a new thread when releasing the firmware. We hijacked this thread.

 

Congrats! Way cool!

...And you are on 1.14B for the cube 3, right?
