His machine works beautifully and he has leveraged it to do a lot of groundbreaking work on getting plastics warping down and improving the surface quality of prints. His original bootstrap printer is plenty robust enough for milling, but is massively overdesigned for 3D printing. He makes it happen and you can see what it takes. If that is what you really want I'd suggest that you take a hard look at what Nophead has put together in that regard on his blog.

A lot of people interested in Reprap seem to be keeping in their secret hearts the notion that if they finesse things just right they will wind up with both a 3D printer AND a workable CNC machine positioning system. Positioning doesn't require a tithe of the robustness of what you require for CNC milling. They weigh 15 and 40 grammes respectively and provide enough thrust to push over six pounds around on the xy positioning table at ~16 mm/sec per axis.Įxtruding plastic doesn't put much stress at all on the object being printed.

[ I use two sizes of these kind of steppers on my Tommelise 2.0 reprap machine, the Haydon 26000 series and the Haydon 36000 series. Instead of belts I'm using linear steppers. It weighs about a kilogram but will power a Darwin with minimal energy beautifully.įor my part I've been trying to evolve a minimal materials mass reprap machine. If you select the right stepper motor you can run Darwin on 0.5 amps at 12 v per motor. I think that you have to ask yourself one very important question, however, "why are you designing a positioning system that needs so damned much amperage?" Mind, not nearly as expensive as buying a higher capacity stepper controller board commercially. As you might expect, they're more expensive, though. One is even pin compatible with the L298 and a LOT smarter inside. I got interested in that idea and ran them down on the web about 6-8 months ago. It can drive inductive loads e.g relays, solenoids, motors (DC and stepping motor), etc.

It is a high current dual full-bridge driver that is designed to accept standard TTL logic levels. L298N is an integrated circuit multi watt 15 package and capable of giving high voltage. Most nema17 will drive at less than 1.5amps but I do have nema17 here that drive as high as 2amps and can't be driven off a 3d printer step stick.There are a couple of h-bridge chips that will deliver considerably more than 2 amps. Features of the L298N motor driver Module. These step stick will at very most drive 1.5amps.

Please post a link to the exact nema17 your using so I can tell the correct amps.ģd printer usually use nema17 steppers and they call there stepper drivers step sticks. These stepper drivers will create the step pattern and also chop the amps at pre-set. A stepper driver is a dual H-bridge with some other added circuits to make it much easier to drive steppers. Usually you will drive a stepper with what is called a stepper driver. This can drive 2 DC motors or 1 stepper motor but it is the gard way to drive a stepper. like all the H-bridges you have posted it is a dual H-bridge (2 h-bridges). Hardware: 1.) The controller can take up to 2 motors.

This tutorial will show you how to use it. Although it is probably a stepper motor servo motors also come in this size.Ītm all the motor drivers you are posting are what is a called a H-bridge. The L298N Motor Driver is a controller that uses an H-Bridge to easily control the direction and speed of up to 2 DC motors. Ok Nema 17 is a physical size of a motor it doesn't tell me what amps or volts it should be driven at.
