I use Inventor and NX at school - NX is the best CAD-software I've used but it's not exactly affordable for personal use... Then there's the free softwares: FreeCAD is the most powerful I've tried and it's absolutely worth testing! It has a wide variety of tools and you can create pretty complex stuff with it. If you need/want a smaller, simpler modeller then SolveSpace would be a good option: siby harmaasilmä - General
Thanks Ramon! That seems like a great shop! I will probably buy some things from there. It's a bit hard to find good shops but I actually managed to find a few from my country and one of them sells quality smooth rods with a very nice price. Unfortunately their delivery costs are quite high (more than the rods themselves) so I might have to buy from Dold anyway, unless I or someone else can go piby harmaasilmä - General
Ok, thanks, I'll keep Ali as one option... But really, has only one person ever bought smooth rods? Maybe everyone else has just scavenged (stolen) them from somewhere...or maybe the seller just was so bad that it can not be recommended... Please post any tips/recommendations if you have - smooth rods are important parts and probably many people would like to know where to get good quality and hby harmaasilmä - General
So, I'm looking for smooth rods for my DIY Ultimaker 2 and I have two problems: how good quality do I need and where to find them. I will need 1pc D6mm x 320mm(X), 1pc D6mm x 300mm(Y), 2pcs D8mm x 337mm(X), 2pcs D8mm x 348mm(Y), and 2pcs D12mm x 339mm(Z) rods. -First the material: I think the best option would be stainless steel but those are harder to find. Then there are those hardened steel/cby harmaasilmä - General
Thanks for the tips! Actually, I found a 24V/30A PSU from my local hackerspace - that surely has enough power! It's totally overkill and quite big too so I'll probably buy a more suitable one later... Maybe I could measure the power consumption somehow and get a better idea on how big PSU I'll actually need... I bought this heated bed - no power rating but the circuit looks exactly like the oneby harmaasilmä - Stepper Motors, Servo Motors, DC Motors
I contacted the Stepperonline customer service and they said that 17HS13-1334S steppers won't be available from EU for next two months unless I make a bulk order. They suggested buying from their main site but that would cost me a lot more. So a JK42HS34-1334 from ebay it will be! Those 17HM19-2004S steppers I will buy from their EU site and I started to think if I should also buy a power supplyby harmaasilmä - Stepper Motors, Servo Motors, DC Motors
Yeah, I thought about that too - I'll ask them about that stepper. In case that wont work I'll probably buy a JK42HS34-1334 from ebay. Thanks for your help.by harmaasilmä - Stepper Motors, Servo Motors, DC Motors
Aah yes, that's true... I don't want to hurt my filaments. Yes, I've noticed stepperonline has more steppers on their main site but the motor will become quite expensive if I order from there. For example that stepper you suggested would be $24.3, shipping cost being more than the value of the product. Also if I order all the steppers from there the order will be bigger than 22 eur ($24,59) whicby harmaasilmä - Stepper Motors, Servo Motors, DC Motors
Quotedc42 I can't advise you on the mechanics, but in electrical terms that motor is fine for the Duet, Smoothie and most other electronics. For the extruder, I recommend using a gear ratio of between 3:1 and 5:1 with 1.75mm filament, and a stepper motor with 20 to 30 Ncm holding torque at full current, with a current rating in the range 1.2 to 1.7A (or 1.2 to 2.0A if using the Duet WiFi).

Thank you very much! I'm just in the beginning of my project so I haven't chosen any parts yet - better get parts that are compatible with each other. I've already thought to use a 24V power so it seems I'm on the right track... (Those are widely used at least in 2d-printers so there must be some reason for that, right? ) I was too a bit skeptical about my first suggestion because the inductanby harmaasilmä - Stepper Motors, Servo Motors, DC Motors
So, I've decided to build my own 3d-printer from parts and use Ultimaker 2 as a base (github). I'm not planning to modify the original design too much but some improvements/changes I'd like to make. One is the XY-steppers: I'll use 0.9 deg steppers instead of 1.8 degs. I'm just wondering which ones would be good. I think Ultimaker 2 uses SY42STH38-1684A steppers (link) for x and y and I've thoughby harmaasilmä - Stepper Motors, Servo Motors, DC Motors
