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...

Re: Some issue when building Oasis 3DP
When you press prime, does any ink come out of the nozzles? Have you ever cleaned the printhead, with either water or alcohol? The correct temperature and 300/300 means the controller can control the nozzles, but if the nozzles are clogged the printhead will still not print.

Re: Hacking the HP45
The old design board indeed required 2x a 2 layer board. This design has been replaced for quite a while though. The new design requires a basic 2 layer PCB to work. For JLC (or any other board house) no exotic settings are required. The only thing that is helpful is gold plating. Most cheap PCB's a...
