While on night shift I had some time to work on an all metal extruder idea I have in my nerd, so far, so good
Hi, I'm thinking of making a Lautr3k but I have problems with the lead screws. I found these on the web for Moore, I think they may be equivalent. I would like to know your opinion. Thanks! http://www.mooreinternational.co.uk/category-18/SPEEDYINCHT12.8-35.6.html
Hi Lluis, Yes as already seen in this topic it can be adapted. But we must machine the ends. Look forward to seeing your build
Looking for someone to print parts for this build. Can't find anyone locally. I would gladly order the filament and ship it to you. Wanting a funky color. (Magenta!!)
Is there any reason you didn't use V-slots everywhere? Do you think that using only the lead screws from openbuilds store would work?
Find a 3D printer near you will be easier than finding the right lead screws. Look at http://www.3dhubs.com. The price and I find unfortunate to waste good linear guides for the structure. Yes i think but not at high speed, @Robert Hummel should easily answer the question, it make a Aluminium version with it.
Yes I make out well before motors stall at anything above 30mm a sec. I'm looking to get 2 amp drivers and bump up to 24v with a rumba board
OK guys, I sent the parts stl's off to be printed, and the printer thinks that some of the parts might need quantities of more than one. The BOM that I saw dealt with the parts other than the plastic pieces, so does anyone have quantities of each printed parts list? He is printing, and wants to do it all together. Thanks
Hi Folks! Is there any way someone (Skarab???) could modify the "x carriage - nut side" and "y carriage" to fit the igus 10x25 lead screw nut??? It appears to have a slightly larger bolt pattern. I've included the .stl for the igus nut. (I'm not a CAD guy...yet! ;-) For anyone interested, I've also attached the quote for 2 nuts and the 10x25 lead screw which is 1000mm long and will have to be cut and machined. Thanks Scott
What nema 17's are people from the states using? The motors in the BOM are really stout from the specs (compared to most I looked at and on the OB store). I already have one of the nema 17's from OpenBuilds store. If these will work well, I will just order 3 more. Thanks
Actually, the ones in the parts list are shown as 4.08 and 4.8 kg/cm whereas the ones in the OB parts store are 5.47 kg/cm.
The ones in the "Parts" store are too long at 48mm for the two "Z" axis motors (40mm max) unless you raise the entire bed.
So I am looking for steppers. Having problems selecting the right motors. Can someone who is/has built this printer in the states make some suggestions?
Hello Digger, I have a good working printer now. First i used a Arduino and Ramps1.4 had troubles all the time and a LOT of noise. Now I have since 3 month a RamBo board (http://reprap.me/electronic/rambo-v1-2.html) Works perfect. you can adjust the motors Amp in Merlin software: In "Configuration_Adv.h // Motor Current setting (Only functional when motor driver current ref pins are connected to a digital trimpot on supported boards) #define DIGIPOT_MOTOR_CURRENT {185,250,60,60,135} // Values 0-255 (RAMBO 135 = ~0.75A, 185 = ~1A) I do have a complete configured Marlin file for you to start with. I use Wantai Nema 17 motors 42BYGHW811 Machine is running just fine, last month over 100 hours Greetings, Dutchdreamer
I looked quickly, it takes a lot of change. This nut is huge !!! and the STL is for 8mm, I downloaded from the website of igus and it is the same .... Nema17 of openbuilds doing very well, and for the Z axis, no problemo, just add some feet to the printer.
@skarab : I'm quite new to the world of 3D printing and I just have some basic questions about your awesome printer : Why did you choose to use lead screws for all axis ? I often see 3D printers which use lead screws on the Z axis (Lulzbot Taz 4, Prusa i3, etc.) but they often use belts for the others axis. What are your reasons for choosing the design "Y bed XZ head" and not "Z bed XY head", for example ? I'm planning to build a 3D printer and I'm esitating between these two common designs. Thank's in advance.
Hi everybody, hi skarab, is there any proven way to build this printer without the lead screws from trinity lab? I read all posts yesterday and there are serveral other lead screws mentioned here, but did anybody made a build with them? Pictures? STL files? Thanks in advance.
I don't know if it will work... but I ordered 2 of these: http://www.robotdigg.com/product/236/Rapid-Threaded-Rod-Stepper-with-450mm-Tr8*20-Lead-Screw (cut to length 400mm) I asked that the ends be machined with a diameter of 5mm. Not sure if I need to modify the STLs or not.. it will be a slow build for me
