Re: OpenDTG Update

 by UVDTG ¦  Thu May 25, 2017 8:29 pm ¦  Forum: General - Start Here ¦  Topic: OpenDTG Update ¦  Replies: 4 ¦  Views: 570

A new kit and controller board so OpenDTG builds can have motorized head height control.

Ooh, I'll probably need this.  I was going to do my own, but at present, was going to save that for version two.

Want any help with the code/design?

Personally, I think I would run the cleaning fluid through it first, then add the UV ink.

That's probably what I'll do if I ever get to that point :lol:

So the cartridge has an eeprom that stores the current ink level, as set by the printer.  When it gets too low, the printer must update the eeprom with a 100% full value. So, why hasn't the communication to the cartridge from the printer been sniffed and reverse engineered?  Is the communication enc...

I don't think it would be possible to over-cure them.  As long as you're not putting enough heat down to actually bake it :lol: I think the main concern with too much power is just that you have to find a way to keep the LEDs cool.  So, you want just enough power to cure it, without making a headach...

Good to know. 

Now I'm wondering if a lower wattage LED on the left side of the head to do a "pre-cure", then a strip of higher wattage LEDs on the front edge would be enough to work.

Is 1/4" wide and 1/4" thick still too big for the right side?  (can you tell I haven't opened one up yet? :lol: ) I also thought about a strip under the front edge, but I've read that (depending on your substrate) the ink has to be cured right after it's been printed, otherwise the colors would star...

At this point I'm kind of planning to make my own that will be much skinnier, and probably have one on each side of the head.  The one on the right will obviously have to turn off when it's over the capping station. But, it may have to be water cooled as well, so I'm not sure if I want to take that ...

It's frustrating because you can't do ink charge on R3000 if you do not have 100% full all cartridges. The only solution remains to buy many sets of chips and change them.... It's so good on P600 to have the resetter. That is what is confusing me.  If you put in a 'new' cartridge and it shows full ...

Did you use an off-the-shelf USB-B extender? 

Are you going to make more/sell those panels for the inside of the printer? 

Edit: I really like how clean it came out :D

There's not a set 'tool' to do that.  For example, I'm making one right now for my laser.  Its work area is 20"x12".  So, I draw a box that is 20x12, and use the laser to mark those edges on its work area. Now, in whatever design program, I draw another box that's 20x12.  Now as long as I start the ...
