Re: AER9 Laser Rifle

This made me smile.

Was TCT any fun?

Re: AER9 Laser Rifle

Impressive, that took you what? 3 weeks or so. That is wicked fast. The reload mechanism was also about half of my assembly time.

Have fun at TCT, and if you get to speak with James Bruton, tell him I really like his Hulk Buster Suit.

I will hopefully see your pictures tomorrow.

Re: Project Tesseract

Impulse purchases are the best purchases (and also the worst). I got the Ultimaker I was talking about. I not only bought it for this project, my old Mendel was also not really useful anymore. It is really something brilliant and exactly what I needed. The guy I bought it from made the frame himself...

Re: Brainstorming: Compact piston drives

The Push pull on one axis is indeed a lot easier, if you want to mount the piston on cables coming from the top, and the bottom (to keep it tensioned). Alternatively, you can also mount springs on the cables if the only purpose of the cable is to keep tension on a system. While the driving 2 pistons...

Re: Brainstorming: Compact piston drives

Another option would be to not wind a cable on a winch, but mount cables to a horizontal linear slide. This linear slide can then be moved with a lead screw. This way you don't have to worry about the constant diameter of the drum and the system becomes self locking. It also is easier to adjust if y...

Re: Project Tesseract

I have not yet considered it. I want to stay away from plastic based belts because over time they warp, but it is mot definitely a possibility to print on PVC. I have no experience with printing on PVC itself, so I have to take your word for it that it is a decent printing material. The current idea...

Re: Brainstorming: Compact piston drives

The constant diameter winch is a good idea. The mechanism that properly fills the winch should actually not be necessary if the distance between the winch and the first guide wheel of the cable is kept somewhat large. I would also add a system to the winch that allows it to be adjusted. This would w...

Re: FPGA + AVR for pen control?

Oasis is the current name of the printer. I don't like to have a progressive name plus I already skipped Plan A. To be honest, I quite like this idea. You only need enough memory for one full sweep. I like to use steppers, but for inkjet I realize that at some point you cannot get the resolution out...

Re: Project Tesseract

Fast forward to now and why this topic is here. I think I may have a solution. Polymers by definition degrade under stress over time. It is what they do, so any plastic conveyor would degrade in under a hundrerd or so prints. Metal on the other hand lasts a lot longer. Easily in the 10.000+ range. M...

Project Tesseract

Named after a 4 dimensional cube, and somehow no one has thought of naming a printer this way yet. This is going to be the first entry of the development of my new FDM printer, Tesseract. The idea has been there for a while now. How to make a printer that makes printing a lot of stuff interesting. F...
