Da Vinci printer Cartridge "factory" reset (Page 2 of 3)

@ToniPons. I think I may have figured what is happening. At the bottom of the serial monitor screen are options for "No line ending", "Newline","Carriage return" and "Both NL &CR".

Newline works with Code 1 as do the others but Code 2 needs to be set to "Carriage return". Nothing happens in code 2 when "No line ending" is set in the serial monitor. I have no idea why that is. But using the second code work well with that setting and as the second code is better I will keep the settings as is. Unless someone can explain the differences.

The Picture shows where the options are and I have placed an arrow to show which option to use for code 2.

I hope this cures the problem.

@ToniPons - Great - I was beginning to wonder whether something else was happening in the code!

Thanks for your feedback and have fun resetting the cartridges to whatever specification you want.

I am not sure that the EEPROM read is correct, some of it looks ok but other parts don't. The cartridge name looks different to the cartridge names I have seen. 
Try cleaning the contacts to ensure a good connection.

Have a look at the sticky at the top, or at my post. The most important thing though is, does it work with your printer?

@Chrislondon - sorry I was not able to give a more comprehensive response to your post - I was on holiday and had limited internet access!
The EEPROM download read from your cartridge doesn't look like any of my cartridges. This is my original stock cartridge reading:

The second line shows the cartridge origin "GB" and I believe the first line includes the colour X or R in my case.
The first 4 lines are repeated to fill the EEPROM.
Your cartridge does show the repeat but the content looks odd, all those 'P's don't look like they should be there.
I have had EEPROM reads similar to that in the past when I used wires that I handheld to make a connection to the EEPROM pads. Sometimes they made a good connection but more often than not I would get garbage.
When I moved to the gold plated spring connectors my problems disappeared and the cartridge programmed OK and read OK.

Have you made any further progress with your investigations?

@Landin81
"didnt get the menu to work but it reseted the filament so it says 120m."

I would be interested to find out why the menu didn't work.
And am also intrigued at how the resetter reset the filament Length to 120m without the menu working.

Did you try with carriage return option? see post to Tonypons further up.

Nice GUI.

There is a lot of information regarding how to program the EEPROM with temperatures and filament settings in the original code by O.Fueckert. What specific help do you need?

Great job and looks awesome!
I love the display. I would like to do the same things my arduino uno.  Could you post the code and setup?  I ordered a similar display used google and Europe site for only $10.  Hopefully it will work.

Thanks in advance.

By the way, I just bought a DV 1.1 plus wifi.  Works great after some minor issues.  The factory nature cartridge did not recognized nor install.  Luckily I ordered extras on Amazon and the spares worked fine. After the issues and researching I came across this and other similar sites, I ordered an arduino uno and tested the code on my cartridges.  Al the 3 extra cartridges worked but factory cartridge still didn't. The monitor window showed the EEPROM was all 00s then it added the counter and increments each time I ran it.  Anyone has ideas or how I can put to use the full cartridge w a bad chip?

I'm a newbie w a little IT and engineering background.  Many thanks!

I've had my 1.1 for about 2 weeks now. Really impressed with the ABS prints, but I've been trying to get mine to do PLA.. having a nightmare to be honest, keep clogging up the hotend connector. The design of the DV extruder component is crap. I don't understand how they can put so much effort into the looks and design and then bundle an hotend design like they have.  I've since removed my hotend and I'm halfway through adapting a MK8 hotend at the moment.. just waiting on a 0.4mm nozzle and then I should be able to print PLA without a problem. :-)  It's quite a straightforward replacement, no holes or anything to drill so you can always go back to the original if needed. I've also now got it working with the original tubes / filament sensors so it installs and uninstalls filament ok. I might try some PLA in it later.. that will be the test :-)

If you have managed to get the faulty eeprom to store the increments of the serial number then chances are it just arrived to you blank. You should just be able to flash a fully cart eeprom to it and away you go.  I corrupted mine a couple of times when I was trying to hold all the wires on with one finger so needs to do this myself. Have you tried the source at the beginning of this thread to reset it?

I am curious. Rather than deal with an empty cartridge and have your display mounted to it, which means removing it when you want alter settings.  Why not just hardwire your resetter straight to the three pins in the machine and mount your display on the front of the machine in a printed enclosure? It would be much easier to make changes on settings and never require the top of the machine to be opened again.

I tried the orig reset code on the blank chip, no luck.  However, I used your factory reset code and worked but it reset to PLA chip and temp while I have and need a ABS chip.  Still after that I tried to change some settings but printer still sees it as a Red PLA roll when I have a ABS roll.

I was able use the roll by changing temps and Len.  Somewhat happy.  I built a arduino uno w a 9v in a printed case then used a combo of orig code w a few mods hard coded for temps length and a ten second delay at the end.  Thus it's a portable ressetter.  The arduino has a yellow LED always blinking and as soon as you touch the three leads to the chip LED will go solid yellow for 10 seconds. Long enough for you to recognize successful reset.  Also I use the thingverse chip case w three holes and loop ends of the three  22awg wires and hot glue the wires in place, works great.

I am able to use 3rd party spool w just the xyz cartridge sitting inside the Printer.  I haven't figured out what the best place to put the spool holder yet, side or top.  Lastly I too have issues w PLA printing. I ordered a real xyz PLA roll so I can do some more testing.

I have to wait 3wks for the screen but wd like to copy your setup, if possible.  I like the clean interface and tetchy screen look.  Lol

Thanks again
