I'm looking for more parts. here is what's next on my list Heatsinks, Purchased : Fan for stepper drivers, can't decide 60mm, or 2x 40mm fans. Multimeter (I need to set my stepper driver current and I want as low a chance to fry them as possible, I read somewhere that the cheaper boards dont have a stop for the trim pot, will a $20.00 multimeter be sufecient or should I just get a good one now aby Zerker - New Zealand RepRap User Group
yes you can run two stepper motors of the one driver for the Z axis. on the ramps board there is one dual header 4 pin that is wired to the one board where the others are only wired to a single 4pin header. this one you wire to your z motorsby Zerker - New Zealand RepRap User Group
Just going to weigh in and throw my 2 cents in. Keep in mind I don't have printer and am only in the early stages of a build. Nophead sells a Mendel90 kit (he is the designer) and its £400.00 plus shipping. The Mendel90 h Seems to have less calibration requirements and could be less likely to go out of calibration with the rough treatment high school kids can dish out. The smooth rods are direcby Zerker - New Zealand RepRap User Group
Yeah you got to be careful with the RAMPS Boards. I checked out the cheap ones on AliExpress and some of them don't have the jumper pins or jumpers for micro stepping. I could have paid less for my one (its even cheaper at the mo, it's all on sale it seems) but it stated it was tested and all the buyers had good reviews for it. Same with the stepper motors I bought the ones Dust recommended as thby Zerker - New Zealand RepRap User Group

thanks for that Dust. those thermistors say they are 2mm diameter I may have to re-think that then. once I factor in heater and thermistor it's getting closer in price to the other hotends out there. originally my plan was to get Magma all metal Hotend, and be setup straight away for printing with all available materials, but the designer no longer sells them and those that do have them in stockby Zerker - New Zealand RepRap User Group
Hi all, Wanting to know if anyone has tried these [3d-industries.myshopify.com] They seem like a nice cheap option and I'm trying to build this I3 as cheap as possible. Has anyone had any experience with these good or bad?by Zerker - New Zealand RepRap User Group
Cheers for that Dust, I should be buying those in a month or so. And yeah scottnz11 they all seem to be 48 long, should fit just fine as Dust said. Also the I3 is a fine machine, but no reason to stop there can always build anotherby Zerker - New Zealand RepRap User Group
Hey dust those motors appear to have hexagonal axels is that a problem? Or do your pulleys fit straight on? I've been looking for other motors but I can't find anything cheaper with the same torque, they are all much lower and more expensive.by Zerker - New Zealand RepRap User Group

thanks for that, I checked out Pololu's website, I never even thought to do so until you alluded to the fact that they are a vendor. the price per 1 is still decent, so I will give the alibaba ones a shot first (cheapest ones) and replace with pololu originals if I fry any. still confused by those extra numbers even after reading the wiki entry for the A4988by Zerker - Reprappers
Hi all, new to reprap, building my first printer, going for an I3 Prusa I have 3 different places I'm looking at buying from, but they appear to sell different models. I have no idea if there is enough difference in each of these to make them worth the difference in cost, or will i not notice with my scratch built printer be more likely to have other isues that will effect the quality of my printby Zerker - Reprappers
Hi, First good luck with your I3 build. The reason for wanting to put together a BOM is so I don't run too short or forget something entirely rather than buy too much. From looking at [78.47.92.212] It looks like I would need almost the same parts as the Einstein variant only the y carriage bearing mounts and the Belt holder are different. As these parts would be to fit the same belt size andby Zerker - New Zealand RepRap User Group
ty, everything I see for the Box version so far seems to work off of the original design which did use M8 threaded rod. I want to make sure I'm going to have the correct printed parts for the box build, but the more I look into it, looks like I could almost do exactly the same as the single plate,is this right? if so I have the RepRap Magazine issue 2 which has the build guide for the Einstien vby Zerker - New Zealand RepRap User Group

Hi all, new to RepRap, live near Hamilton, and looking to build a Box Frame Style Prusa I3. I've been going Prusa's GitHub trying to get as much of the BOM from there for what I guess you would call the original build. however it seems to be missing some information, is there anyone here more fammiliar with the Prusa I3 that might be able to fill in the blanks? from the Wiki I see no one has aby Zerker - New Zealand RepRap User Group
