I was aware that I hadn’t linked it yet, but I will do so tomorrow.
I am actually happier that you posted something, it went for approval, and I still have to decide if I want this for new users.
If there is still anything wrong, please tell me so, so I can still fix it.
(an edit 30 minutes later, in a big why not moment, the new forum is linked properly and the user registration for this one is stopped). For the die hard Ytec3D community (heh) it is still possible to post, but I’d appreciate it if the conversion to the new forum could be made. Your first post may go for moderator approval, but I have already tried to fix that issue)
The new forum is kinda sorta running. I will make some (probably a lot) of tweaks, but for anyone loyal enough to actually come here, have a taste and give an opinion.
First tests were a success, the new forum should come online this weekend if nothing else gets in the way.
Looking great. Printing density at 2 sweeps seems to be just right. Also the lines seem very crisp. I am convinced that if you would have good test results on any printer, it would be this one. Can’t wait to see more.
I am considering adding a stand alone forum to this site. Thus far I am far from impressed by this one, and the longer I wait, more damage it will do. I cannot convert the old forum to any new one, but I can eventually copy the posts here to the new forum, for legacy purposes.
I can’t tell when I will add the new one, but the traffic has died down a bit, so I might start preparations this weekend. I still need to do a local test to see how I have to get wordpress and something else, running alongside each other.
I had a huge problem with spam registering, and have fixed the problem. I did a crude cleanup of the registered accounts. I tried my best to only remove the spam registers, but I also deleted a few non-spam users. These have been converted to anonymous.
Sorry for this. There is no real way to get you back, your posts are still here, only you’ll need to register again if you want to make another post.
Hi Wonko,
I removed the math thing, I like it already, but I had to get a different filter to stop the spam registration problem.
I will keep the laser in mind for the next design. I would love to share ideas with you about the next printer, so when you are ready, either start a thread or mail me. I am sure that the both of us can come up with something great.
Your digitizer looks great. I like the way it is constructed. How long would it take to get a decent duration of film digitized. It looks like a fairly slow process.
That looks great, There aren’t that many Glados lamps out there. Great Job. Are you going to make it moving and/or lighting your room or do you keep it as a prop.
Hey Matthias,
Good to finally see someone else after 2 months. I was beginning to suspect that it was still broken. I’ll consider removing the math thing, because I think it doesn’t stop anything.
3D printer status report from my side is also unchanged. The concept for the next printer is done for months, but I actually have it planned for this winter. It will be easier for this one to use other printhead, and overal I hope that it will be cheap and good for testing new printheads and materials. Less axes (no more 6 stepper motors), and a bigger printhead carrier. And most importantly, a heated environment.
Plan B experiments are completely done. Plan B is running on it’s last legs and I do not feel like overhauling it again. The new faster controller does work, but I don’t know if I will make a version for sale before the next printer. For now I am busy with more props.
Both of the bottom left sets of headers need 12V. The bottom one is the power input for the megatronics. There is also a header on the Megatronics above the USB. This is the power select header, and it toggles between powering the Megatronics from the USB or from the 12V. If the megatronics doesn’t power, it is because the header is on USB power. First get the megatronics to work, and if that works, connect the boost demultiplexer with the 12V terminal to the 12V5A power supply. Hopefully this time it will work (because I do not really know what is going wrong without more information)
I actually soldered to the C6602 once, but I really can’t recommend it. It is nearly undoable. You will need a level shifter for your 595, the C6602 printhead takes 20V at high currents. the ULN2803A is what is used most. You can not trigger all nozzles at once. Not only will the cartridge itself not like it (it is designed for a cascading trigger), your voltage circuit will also not like it. Don’t underestimate just how much power inkjet uses, some printheads have recorded currents of 300mA per nozzle.
The C6602’s are quite fragile, but I have one that I have been using on and off for half a year now. But just in case, for the coming makerfaire this Sunday, I did prepare 2 more.
As for the picture:
Hello,
The 12V port should indeed be wired to the 5A 12V socket on the megatronics, but the capacitor should not explode. There is several ways a capacitor can explode. First it can receive reverse polarity. Make absolutely sure you a: wire the 12V the right way around and b: solder the capacitor the right way around. Another is over voltage, but at it’s current location, it should only receive 12V. However, close by on the circuit, it is boosted to 20V, so maybe I did wrong and you need a 25V capacitor. I always had 25V capacitors on mine. Maybe it is bad caps, but if you already blew up 2, this seems unlikely.If you try with a bigger cap and it doesn’t explode, please tell me, then I will fix the site immediately. Else send pictures (either through the forum or mail) and I will work from that.

The Q2347A has indeed 16 contacts, but 2 are not connected and 2 are for power supply. That leaves 12 pins, one for each nozzle. If you are referring to the electronics. The 4067 has 16 outputs, but only 12 are used. BTW, I refer to the Q2347A as the Q2299A. It is the same component, but it might cause some confusion.
Was the thing about the photo a conclusion or a question. If it was a question I will add a picture to this thread.
