Re: Standalone controller V4.0

The HP45 controller was (and still is) intended for sale somewhere in the future. For this I wanted a fast and thorough way to test each controller before it goes out. The ability of the controller to do some of the tests itself helps, but it is not perfect. PXL_20220117_194314316s.jpg h2g-6T0V7IM F...

Re: Hacking the HP45

ESP32 is actually a bit short on pins. It should have enough pins to control an HP45, but there will not be many pins left for other things the way I drive them. The ram and other peripherals are very nice though, so it might be a cool idea. I have no experience with driving HP45 with an ESP. I do k...

Re: Empiric 3000 3DP printer

A professional looking glovebox. The syringe is a great idea, I have been struggling with mine to handle the air tool while wearing gloves. I am curious to see how visible things remain when you are cleaning thing. My previous attempts the powders blown in the air made looking into the chamber diffi...

Re: Hacking the HP45

That is the only one right now. With the HP45 V4 controller I am still to write a new version of that document, but chip shortages, some setbacks and lack of time has hindered that project for a few months now. If there are specific questions feel free to ask, I am sure I can help if you need. As fo...

Re: Empiric 3000 3DP printer

I was not familiar with ribbon mixers. Neat to know. Dental plaster supposedly works well without additional binders with water and alcohol. I have also heard Maltodextrine works well instead of sugar. I have not tested any of these myself. I discovered that I really did not enjoy material studies. ...

Re: Hacking the HP45

I am not really sure how it does identify the printhead. I know there is a bunch of resistors in the head that measure different depending on the polarity, but I have not had a deep investigation in how this is used to identify the printheads.

Re: First Layer Issue

It has happened to me as well. Increasing the layer height or decreasing the amount of ink ejected can help. The rolling spreader helped much, but Plan B does not really fit one very well.

Re: Empiric 3000 3DP printer

I first thought it was a ballmill. It looks like a great mixer. I like the usage of random parts and controllers to make it.

Re: Empiric 3000 3DP printer

That was an amazing write-up. You can certainly see the Oasis legacy with a lot of improvements. You can see that you put a lot of work in designing and building this. I like how robust the pistons look. This is a weak spot on my current Oasis. You have a resin printer? I see FDM parts, but the prin...
