DaVinci Junior cartridge reset (Page 28 of 58)

Hi,

I've used Hatchbox Red and BAMtack! Blue at 190C. How are you printing at 215C?

I'm not sure if the instructables reference is in response to my question about 215C. If it is, I was asking about that temperature, since I don't think that any color has been reported to print at that temperature on the printer, so was wondering what was done to do that.

- thanks

I can confirm that arduino uno R3 with RC522 shield is also working, both reading and writing to the tag. A small change in the library was needed to be able to read all pages.

Come on and help the guy out. I would, but I do not have the resources to be able too.

All I ever see from you is someone asking for more information and money. This forum is supposed to be here to help people learn, not profit from the information being posted.

Do you know which version of XYZware ?  I found and downloaded a version 1.1.30.16;  It did not have the Da Vinci Jr as an option at all.

Was this workaround for tethered printing, or did it also work for exporting files as well?

TIA!

http://www.soliforum.com/topic/12741/xy … nced-mode/ it can tether or export

Thanks, Everyone!

Using the advanced mode executable:
After choosing to export, and selecting print settings with the wizard, I was able to insert a temperature change line into the gcode (via the tab_gcode _editor tab) , hit the save icon (still on the gcode tab) to create a .3w export file.

I took the exported file on SD card to the printer, and started the print.  The display showed the extruder heat up to 185c and then the print head moved to the right to lay down the cleaning strip.  Here, the printer paused, and I thought that I had damaged the export file.  After a couple of seconds wondering what to do, the printer layed down its purge strip, and began to print.

There was no way to view the temperature from the machine while it was printing, however, I was able to start and cancel a print, and the status monitor showed the extruder at 211c

I used white Hatchbox PLA, which has a recommended temperature range of 180-210c
210 may be too hot for the slow speed that I chose, and may have added  a few small strings and blobs.
My previous attempts at benchy, using the default speed and 185c temperature all had holes in the sides , and floors of the ship.   

The result was the best  3dbenchy I have printed to date on my jr.

Hi everyone,
j write the old tag and successful ...
ok
in the page 0A,0B and 14 j write data 300
but in the printer info spool is indicates spool capacity 231 and sppol remaining 196 WHY ?
Thank you in advance

Cecil,

I finally got around to getting it to work.  My clamps didn't hold well to the proper pins, tried getting in by baring the wires and clamping there, but finally ended up soldering some leads onto the pins.  Read my PW, reset my 100m NATURE sample spool to a 300m Red Clear and printing away just fine!  I have some generic 144 stickers from eBay that I will try to program for my 5 spare spools.

Anyone know the color code for BROWN?

Thanks for your input and the help of this forum.

Next to do:  I have generic spools from eBay, but they have a wider and larger inner diameter.  The original XYZ spool is 2-1/8 wide with 2" center hole.  My generic spools are 3" wide with 2-3/8" center holes (1lb or 2.2kg by weight, unknown length).  I am trying to print the spool collar long enough for the replacement spools, but I may have to disassemble the original spool holder inside the machine and print it longer as well.  I will post results when completed with this mod.

I have a theory that 0E in hex or page 14 in dec is part of the temperature override for the tag. 

The digits are typically always 30 to 39 in hex which when converted to ASCII are the numbers 0 through 9.  I've seen a tag with what would be 0 1 9 0.

I think it is where you could set an override of the default by color temp. 

I tried a bunch of different combinations in those bytes to see if I could come up with a combo that would over ride the default without success. 

I'm kinda thinking that is where the override temp is set, but some other byte or line activates or tells it to use that value. 

Anyone playing around with different combinations of data to write?

I tried a bunch of different values and it would read and use the tag normally, so that is why I'm thinking something else tell it to use it. 

I would think one of my values of FF FF FF FF would have given some kind of error, but I think it isn't even using it without the other byte or line telling it to. 

Any thoughts?

Are you referring to the E0 in E0930400 ? Someone else had already shown that value is for 300 meters (well, I suppose 300,000 millimeters, actually). The network-byte-order version of the little-endian E0930400 is 000493E0 which is 300000 in decimal.
