Thx, For some reason my ptfe tube is a bit stubborn. i'll just start small for now.by BackEMF - Smart_Rap
Thats chunky aluminium, looks good.by BackEMF - Smart_Rap
Tomorrow i'll try to get the electronix all wired, the glassplate that will be extra weight hehe And i have to order a good quality PLA... So i'm still at some distance to get printing. BTW how should the steppers be jumpered? Everything 1/16 or X and Y 1/16 Z and E 1/8 ?by BackEMF - Smart_Rap
Verteez, you are a perfect help to the project, support is not an easy task. Serge has his hands full with MANY MANY tasks. im going to put thermal greese or a silicone pad between hot end mount and heatsink. (if i don't forget it)by BackEMF - Smart_Rap
Mike, If you put the Y and te Z axis both in MAX position. Is your PTFE tube then long enough?by BackEMF - Smart_Rap
hehehe, ok the X rods will have to stay now...by BackEMF - Smart_Rap

Thx thx, Y axis is about 40 CM, I sacavenged them from an old XEROX copier. Closed hardware shall be opened!! I'm not sure if I keep them on the SmartRap 40 CM takes op about 80 CM when printing. But I must say, dispite the lenght, is still feels very stable.by BackEMF - Smart_Rap
Guys, here are my first steps. The mechanical build is ready. The build went pretty smoth so far. And I'm impressed how Serge manages to produce so many kit's already. I have the RAW kit, and i must say it was more work then expected. Though this makes me appreciate the machine much more. :-) I wonder where Serge finds the time to source parts, print parts, produce kit's, test upgrades, writeby BackEMF - Smart_Rap
Serge, I received the RAW kit today. :-) My compliments how you managed to produce this many kits already. The aquarium tube's inner diameter should be 4mm. With needlenose pliers you eventually can stretch the tube a bit. It might be an idea to let the PTFE tube exit on the other side? Personally i whouldn't mind if the extruder would be a seperate unit instead of integrated in the base.by BackEMF - Smart_Rap
There is no assembly documentation of their printers and they make several different models. I think the best chance to get an answer is here: skype: come3d.printer Email: come3d@163.comby BackEMF - Printing
Darwin passed out. ...unable to keep up with evolution :-) Nice rappers regpye!by BackEMF - Smart_Rap
Nice one Whosawhatis! I will have a deeper look into this tomorrow, thank you! First things that come to mind are What about: - material density (kg/m3) - crimp propperties? ABS crimps when it cools down how much percent or mm of crimp per meter or is this for all ABS the same? though i supect that all the materials like PET, PE, PC, Flex, etc have different crimp caracteristics. This could eby BackEMF - Printing
Quotenothinman Unfortunately the idea with pulling it out of the box won't work with current 3D printers, since it's coiled, and by pulling it it would effectively go into the extruder twisted. But it won't untwist there, because it will hold it tight -- so it will create more tight coils inside the box, leading to entanglement in the end. An alternative way would be to pack it into the box in thby BackEMF - Printing
Nice build Verteez! I've done some research on knots Using the right knot (that doesn't slip) seems to be the key. And there ar MANY knot's to choose from. I wonder if there are fishermen around who can give us some advice. Now, we are not pulling a shark out of the ocean, but still it would be nice to learn (or create?) a reprap knot. Aquarium air tube with an inner diameter of 4mm works nicby BackEMF - Smart_Rap
Would be nice to see some pictures side by side of a filament drive that prints pefect and one with skew issues. What thickness is the line? How many turns on the motor axis? Line tension? What about a short youtube clip of the behavoir of the wire when printing? What i like about the fishingline is that it results in a higher print resolution. the radius of the motor shaft or GT2 pulley devideby BackEMF - Smart_Rap
Interesting discussion, and I wonder if a standard is a good idea, or even possible. I think that an open evolution will eventually result in better spools. Then there are also the cardridge based spools... What happenes with empty spools, are they collected and re-used, or trashed and recycled, or worse ...landfill? How much energy is involved when collected and shipped back to the factory vby BackEMF - Printing
Quotebotbuilder The two on the left were printed together. Their slant matches each other (they were facing each other on the plate). I printed the middle one again separately and it is on the right. Hi Botbuilder, The skew is more on one side if i see it right? Did the scew occure on the side or in the center of the buildplate? And was the scew more on the X or on the Y axis? My first gueby BackEMF - Smart_Rap
