Re: Standalone controller V4.0

Hello, The I2C pins are broken out, but are not implemented in any way. There is no plan on my side to add the I2C to the functionality, since I stopped working on it. It should be technically feasible, to at least print over I2C, but I do not know the max data rates that you could get. There might ...

Re: Hacking the HP45

Short answer: It is difficult without new electronics and rewriting the code. Longer answer: The V3 that is shared on hackaday in Oasis is the easiest to convert to a new microcontroller. This version did not use DMA and all sorts of fancy tricks to get the speed up. It does have some hardcoded elem...

Re: Xaar1002 printhead test video

Youtube videos can be posted using [youtube]{code}[/youtube] where code is the 11 digit video code of youtube, in your case "Yx_BR_mwlbM"

I have attached your video as an example

Re: Dummy 2 not rising error

Is it dummy 1, or is it dummy 2. It does make quite a difference which one is not working.

If the head does test 300/300 it is an ignorable problem. The self testing is a bit finicky and has false negatives. The controller will work despite warnings and errors.

Re: Dummy 2 not rising error

The prime line should be 2 solid lines. The fact they aren't tells me nozzles in the missing row are clogged. Preheat should not be ejecting ink. Only purge should really eject ink. The image usually does not print with a lot of ink. It depends on how you set the printhead (DPI and density determine...

Re: Dummy 2 not rising error

Just sending an image won't make it print. The system is designed around having an encoder to print (it has it's roots in Oasis). It requires a position of the printhead to print. What is easiest to do is set the printhead in virtual velocity mode. Here it will pretend to have a movement at a certai...

Re: Dummy 2 not rising error

Hello, I also saw your mail with this question. I will answer it here so the potential fix may be visible to other people. Dummy 2 is one of the two resistors used to test the test circuitry. Dymmy 1 is for testing without a printhead installed, Dummy 2 is used for testing with a printhead installed...

Re: Buying an Oasis 3DP or Plan B ??

If I knew someone I'd refer you to someone, but I don't. All I have seen is small groups of people replicating the design, and I don't know anyone that would do this as paid project. Oasis sadly is a bit of a niche machine that is really more of a prototype, not a fully functional machine.

Sorry, but at this point in time I am not working on inkjet and powder printing stuff anymore.

Re: Buying an Oasis 3DP or Plan B ??

I do not, and I do not know of anyone who does sell them. The original design of Oasis also calls for either a Teensy 3.2 or Teensy 3.5, both of which are no longer available, so I doubt there will be any people who can produce them. Plan B is ancient and not really that good of a printer to begin w...
