The i3200 heads are offered to aftermarket suppliers and are way better and far cheaper than the clunky old DX7 stuff. Epson absolutely keeps their best heads to themselves, but they are finally releasing modern heads again.

Will hook you up when I get home. That one linked won't do a UCJV300.

Yeah, that is a total rabbit hole of BS. Firmware update requires a special software too given to tech for most current printers.

Being able to design a flatbed, conveyor, roll, jig or press style printer that can be built from a kit or pre-built for well under half the cost of existing printers while still getting modern hardware would be pretty powerful. Also, the things you don't get would be nice. Set the ink channels...

We mix specialty inks, so we're building a test printer for that amongst other things. We also have a big stash of heads we might turn into a big flatbed UV printer for doing things like signage and such. Mostly just wanting to open the tech more to tinkerers more than anything else.

After doing lots of homework on the hundreds of dirt-cheap Chinese DTF, solvent and UV printers flooding the market, I figured there had to be some basic ecosystem to them. Most of these printers are based on commodity parts, off-the shelf printheads and tend to share a vast array of parts...

The 3DUJ printers from Mimaki take it to the extreme. But they also have special dimensionally stable inks, dissolvable inks and a special roller that smooshes the print flat between layers. Just basic canvas fiber type texture, or fake brush-stroke style layers can really add a lot to a print...

Newer Mimaki flatbeds (JFX200-2513 EX, UJF-7151 PLUS II, JFX600-2531) and their new UCJV330 all support it as well. Not terribly hard to make work on most UV printers if you can do 4+ layers. If you feel really crazy, you can generate sliced 3D model images for a resin-based 3D printer and use...

EPL boards are pricey mofos. Here's hoping it is something silly/cheap. Description hints at a stack overflow, so corrupted firmware is my guess. That said, something zorched on the board can cause similar issues as well. If they have the super secret firmware/parameter tool, then they can...

Welcome! And don't worry, I am sure 80% of the active people here are still learning to interact with others.

Looks like a possible parameter/firmware issue based on service manual. Could be the main EPL board, or a parameter and firmware reload *might* fix it.

If I remove the subtanks, I will need to add some sort of inline or reservoir heater. Doesn't need to maintain more than 45C, so not hard, just time consuming to spec one out. Already building another printer from raw boards, heads and other parts, so not a lot of project time open at the moment.

Bottle tanks use a float sensor, so need a magnet taped to the 3 zone hall effect switch to bypass those.

Perks of having a company partner who designs circuit boards and firmware for a living, and loves open source stuff. Pretty much all the kinematic stuff is done, waiting on the dev stuff from Epson for their heads. Glad they started pushing the 3200/1600s out for development. The XP600 heads are...

I have the firmware cracked so I no longer have to use ink chips at least. Bypassing subtanks might be pretty tricky as I would need to loop in the entire ink system in a different manner. The subtanks also pull double duty as the heaters are located on them.

Alright, another UCJV300 user! Hours on those aren't printing hours, but you definitely got a bit of square footage on the thing. Thankfully, the printers are great in my experience. Got a 2016 model myself, so really early production and it lacks the curse of most early versions. With how silly...

Can try removing the filters from the system and gently pushing UV cleaning solution or isopropyl alcohol through them in the opposite direction of typical flow. If there is a lot of resistance, might be a good idea to just replace the things. Might not be a bad idea to flush bottle stations and...

I don't think I will see any difference if the apocalypse comes. I will still be salvaging printers and using junk pile parts for cheap customers who claim that everything is too expensive while their resident old fart is constantly looking over my shoulders telling me OEM parts are better.

At this point, I am writing the printer off as a massive lemon. So many idiotic design decisions in the early units, every expensive repair and every part that takes weeks to get just leads to another. Why some idiots at Mimaki decided to put in some horribly complex subtank system when Toshiba...

Yup, might have lost prime on the pump and it's not circulating.
