Thanks for the advice, all. I'll try to remember to quote the post I'm replying to. A bit of a noob. O well.by Cinnerman - Reprappers
Good idea. When you mentioned locking the fitting in place I immediately thought about the Teflon-lined braided metal brake lines on my car. Maybe that would provide an adequate lock. Thanks for the advice.by Cinnerman - Reprappers
Great! Thanks, that's the best kind of advice. I was thinking of putting the extruder on a pivot that would keep the bend radius of the tube from getting too radical, and therefore allow a shorter tube. The extruder could be central or off to one side of the frame. It may help with feeding filament up from under the printer. Thanks again!by Cinnerman - Reprappers
Would you recommend it to be mounted on the Y axis structure? Could it be mounted on the frame? Actually, it may counterbalance the Y-axis motor. Thanks for the advice.by Cinnerman - Reprappers
Hi All, I'm building my own large-format printer (1m X, 500 mm Y, 500 mm Z) and I'd like to have some general recommendations about installing a Bowden extruder. Should it be made to tilt as the Z axis rises? Should I mount it on the Y axis gantry so the tube will not have to be so long as to move in both Y and Z? What would be the longest distance I should run a Bowden tube? I purchased an Aiby Cinnerman - Reprappers
I wish that was my kitchen table. May I confirm that you recommended using the high lead screws because of the print speed or accuracy? I expected the shorter lead would allow better accuracy, which is what I was trying to achieve. Is that obviated by micro-stepping? I apologize for the newbie questions, and if there's a more convenient source for ballscrew information would you let me know?by Cinnerman - Reprappers
P.S. - I was wondering what the red and green tubes in your photo do - is this printer actively cooled? Why is that plate where they connect spring-loaded? Thanks again. Cheers.by Cinnerman - Reprappers
Wow! Very cool. Thanks for showing me the CNC stuff - that is quite impressive, and probably more of a long term goal for me. May I assume you are recommending more lead because the axial motion will be speed constrained? It was my (newbie) thought that 4mm of lead per turn would allow greatest accuracy and repeatability - am I way off on that? Thanks for the advice, unfortunately the hardware haby Cinnerman - Reprappers
Wow, very cool design. I'm doing something sort of similar - here's a shot of the first iteration of my frame. It's going to be expanded to allow a 1m x .5m x .5m build area, and I'm planning on using ballscrews for all the axial movements, 1 for X, 1 for Y and 2 for Z. The design is based on Mendel i3 electronics. Jhead and Bowden extruder ordered and on their way! I'm going to use 80/20iby Cinnerman - Extruded Aluminum Frames
I buy a good bit of stuff on amazon and I'd appreciate having realistic reviews, if you don't mind, and particularly when items come from China, since it's so difficult to communicate effectively with Chinese vendors and such a hassle to return things that aren't as advertised.by Cinnerman - Reprappers
Hi All, The plans for my self-designed 3D printer involve using one RM1204 ballscrew for Y and and two for Z axis motion, and an RM1605 ballscrew for the X axis, all on 8020inc linear bearings. My build volume will be 1000mm x 500mm x 500mm and I'm using 40 series t-slot extrusions from 8020inc for the frame. I'm wondering if anyone else is going this route, and why or why it may be a good (orby Cinnerman - Reprappers
Hi All, I'm building my own 3D ptr using an StDuino Mega 2560 "Arduino-compatible" board with an Ultimaker RAMPS 1.4. After lots of hassle trying to connect I found the correct USB driver on the manufacturer's site (Makerlab.me), since this does not use the FTDI USB chip. First Problem: The USB > COM port driver appears to have installed correctly, but when I connect the USB cable Deviceby Cinnerman - Reprappers
Hi Reppers, I'm assembling my own 3D printer and have a question: can anyone tell me what the color code is for the NEMA17 motor leads? Is there a source for the pinouts on a RAMPS motor driver A4988? Will I fry a bunch of stuff if I mis-connect the motor? Many thanks, Cinnermanby Cinnerman - Reprappers
