I am s It works, but not yet cleanly and reproducibly. Some serious weaknesses have emerged that require a rethink. Apart from the very surprising partial unsuitability of PETG for small parts (things keep breaking off), there are problems with the current position of the stepper motors. These...

This project is getting more and more side quests. There are several challenges still to be solved before I can publish the project. It will definitely not be a project for beginners. Even with detailed instructions. Material compatibility is a big problem. I have noticed that PETG is not as...

THe BOM is under 120€. I will publish the print files and instructions. I don't plan to sell it assembled or as kit. For moving a 2500 series or even 3010 it may can adaped to fit in a full Euro-Box. This version with 1/2 Box can only handle the 1500er series.

This summer I completed my self-designed RA-4 film processor, and that was the ignition point for an older idea: to build a small, semi-automatic rotary film processor in the spirit of the classic Jobo CPE/CPP series — but 3D-printed, stepper-driven, and compact enough to fit in half a Eurobox...

216 mm width, 177 mm height and 7.5 mm thick. If you can use SketchUp you can PM me and I send you the complete assembly as *.skp FIle.

I have no sealing at all, as the gears are submerged. Like the original Durst Printo design. I anyway use POM bearings that work great submerged in the chemistry.

Sure. I will try to publish all needed info. Yust need some more time.

I first develeoped a new controller that is able to control the simple WS2812b but also PWM with Cree-Style LED's (with correct wavelenghts, especially red 660nm and green 550nm). I will build a small lighthead for my 605er with the cree LED's. in btw this is the result of the 4X5" enlarger...

Another update after a little time has passed. The system is basically running, but I had to correct a lot of small things. What I noticed (and partially corrected): - The gears also transport liquid above the fill line. This caused developer fluid to get into the gears of the transport roller...

In the meantime, I completely dismantled the machine. I didn't want to do this at first and wanted to wait for a few more tests, but I noticed that I had lost about 60-80 ml of developer. The machine had “sucked” it out. At first, I thought it was poor PETG printing, but it turned out that some...

I certainly hope so! Thank you! I've read some of your blog posts and find them to be some of the most comprehensive and in-depth you can find online. Impressive. I'll be sure to send you a DM if I need more details. At the moment, there are still many issues to be resolved...

Okay. I have now conducted tests with RA4 Chemistry. The good news: it works! I used it for 3 hours in a row. The downside was that I burned out the power supply for my M605C (I think, it just doesn't work anymore) and had to use a prototype LED light source that I had built once for this...

I did the wet start-to-finish test. Nothing serious yet, just with already developed prints and plain water in the modules. I wanted to see how the modules empty. In the first older module (v 1.1), there is a tendency for a few dozen milliliters not to drain properly because there is a...

Thanks man. Steppers are now working stable. I use regular no-name A4988 drivers. The main problem was a weird cable going from the driver to the stepper itself (so not the STEP/DIR signal from the Arduino Nano to the A4988 I assumed initially wrongly to have troubles). I needed short stepper...

Till now it's fine. I will see when and if I add a 3rd module if there is noise with longer cable lenght. Then I will may go for shielded twisted pair cable, by ripping away the insulation of a cat 5/6 cable adding the power line ouside the shield and wrapping it again. An elco on the power...
