Once the drivers are in you can remove the 3M stickers from the heat sinks and place them on top of the chip on each driver.

It might make for a very tight fit and in cases where it doesn't fit, you may have to file some of the edges from the stepper driver. In the image above you can see a gap between the top two drivers, whereas the bottom ones barely fit.

I hate to say this but, sometimes you'll find that the bays for these stepper drivers are too close, or the edges of your stepper driver are a bit too wide. If you are still unsure: Find a labeled pin on one or more corners of the stepper driver board (DIR, GND, ENABLE, VMOT) and match it up to the RAMPS pinouts. fellow instructable member reschchrissi added a useful image in the comments (Thank you!). If you use other drivers like the DRV88 or the TMC2xxx they will be different. When inserting your stepper Driver MAKE SURE THE POTENTIOMETER POINTS AWAY FROM THE BOARDS POWER END (GREEN CONNECTOR). VERY IMPORTANT!! Note how the drivers A4988 Stepper drivers above have a little potentiometer on top (this little phillips screw). Make sure they are on straight, it's easy to plunge one of these past the actual pin.Īt this point you can insert the Stepper drivers (assume adding all 5 X, Y, Z Extruder 1 and potentially Extruder 2) For 1/16th stepping you need to add three jumpers under each driver.

In order to instruct the hardware to use 1/16th micro stepping, jumpers are added between the banks in which the stepper drivers will fit. What's important is that for the RAMPS 1.4 most precise stepping is 1/16th micro stepping (16 x 200 = 3200 steps/rotation). step angle (200 steps/revolution), the micro stepping becomes a multiplier. I'm not going explain what exactly it means (there is plenty of articles on that). It best to use fork connectors and ferrules for better connectivity:įerules kit (comes with proper crimping tool): Amazon $25.89 įork terminals: Amazon $6.69 Step 2: Assembling the RAMPS 1.4īefore adding the Stepper Drivers you need to decide what type of micro stepping is needed by the 3D Printer. It was pointed out, some of the pictures show wires directly screwed into components. Heated Bed $31.99 (optional but will describe wiring) Stepper Cables: $9.49 (these are specific to RAMPS) The fully wired Limit switch (with cables): $7.98 You can choose from Direct Extrusion (motor on the Extruder) or a Bowden type of extrusion (motor feeds filamant through a tube to Hot-end) but it won't make a difference in hooking them up.įor this setup I purchased a RAMP 1.4 Kit which has all components needed to setup the controller boardįor end stop control you can go with two options (I will discuss wiring for both): The Type of extruder you purchase is up to you. In the Laminated Prusa I3 printer the only electronic parts I added were the Nema 17 Stepper motors and the MK8 Extruder.
