Re: Sources for extruded aluminum profiles - 11 years ago

Also chiming in for US suppliers - McMaster-Carr carries extruded aluminum (I think it is 8020) and I am always amazed at how cheap their shipping is.

Re: mendel complete kit. - 14 years ago

Well, by defination, it is a repstrap as none of the parts are printed. I would agree that the price point was good, however, at it's current price, I would not buy it again.

Also, a word of warning... For all of the boxes that James shipped to me, I would get a shipment notification. Some of the emails came from him, some from paypal. In either case, this is when he printed the label. Usually, this was a week or TWO before he actually shipped the boxes. A question to all who have gotten their kits... can someone tell me which thermistor he is using? Unfortunat

Re: mendel complete kit. - 14 years ago

Kris posted in the electronics forum with a question regarding making sense of his heater/temp circuit. I threw out James's idea - partly because he has two different circuit diagrams on his site and he did not provide me with all the parts needed to do either one. I have gone with standard reprap circuit for the heater/temp and it is working. Cost me $5 including shipping from DigiKey. I w

Re: Catalyst Circuit Questions - 14 years ago

Kris, I was trying to make sense of his diagrams. I finally decided to throw out his ideas and go with more standard reprap design. James did not provide me with all the parts to do either of his diagrams. I bought all the parts from Digikey that I needed for a little over $5 including shipping. I got the heater and temp sensor working yesterday. I will post the info later today. Buzz

Re: Top Mount That is essentially what I did. I took a threaded rod and cut it into 3" pieces and threaded those into the couplers. Mounting the feeder on one of those wings is one of the options I am considering.

Re: Assembling Profounddevices Mendel RepStrap - 14 years ago

I have my profound printer fully assembled, with the exception of the extruder circuit. I know how James intended it; however, my kit was missing the 1K resistor and one bearing. I emailed him a few days (perhaps a week) ago about this, but he has not responded. It really is not an issue for me - I am not using his extruder drive mechanism. I do not have faith in it and did not want to wast

Re: Most current set of Mendel Parts - 14 years ago

The places that I looked at do not charge for support material, only for the volume of plastic. I can not remember which one it was, but they stated that if you create a hollow space with no opening to the outside, the support material would remain in the void. I contemplated designing a hollow box and having them print it, just so I could see what they use for support. Buzz

Re: Concept for negative-Z 3d printer - 14 years ago

@Eagleton - Interesting idea. In order to use the play-doh as support material, it would have to be fluid enough to flow into the holes that are being made (instead of the teardrop holes). I'm not sure if play-doh can be made fluid enough to flow into a model and remain rigid enough to support the piece as a whole. Perhaps it can... The other concern I have is if you are pushing the model int

Re: mendel complete kit. - 14 years ago

For those that don't keep an eye on his youtube page, James has posted a new video. Making a raft and starting to print a circle @Jeffrey - I got the larger one to mount on the y-axis. Not anywhere near the way James intended - but it does not budge... I'll post pics later. I do not know what the white plastic is that he is using, however, it is much better than the yellow stuff...

Re: mendel complete kit. - 14 years ago

@Jeffrey - It looks like you might have the motors backwards. The all black ones are the high-torque motors that James intended for the x and y axis. The silver/black ones are for the z-axis since it does not have to move as fast and there are two of them, there isn't as high of a torque requirement. I might be wrong in this... if you think otherwise, let me know, because I would have to swit

See this post regarding english substitutions. If after reading it, you still want the substitutions that I was working on, let me know.

@Kelly - How James tightens his bolts is one thing... I tighten mine with wrenches. Since he is selling the kit, not a fully assembled unit, this is not an issue to me. I have already made a few changes to his printer as he had designed. The extruder-grip method is one place I plan on changing... At this point, I am just waiting for his extruder kit to ship.

@Jeffrey - One note I have from when I assembled my frame... it might be a good idea to get some regular washers to put between the lock washers and plastic parts. I was leery of the lock washers against the plastic, but did it anyway. The few that I had to loosen to adjust really dug into the plastic and tore it up. Just food for thought. Buzz
