Again, if you bought your electronics from here this has already been done for you no need to continue on. The firmware is what makes this all possible and was the key for me to quickly make all sorts of robots. He is not the only one but has been a huge factor in getting the firmware to the place it is now. If you can drop a dollar or more his way to keep this project advancing click the link above.

This is an advanced feature and the information will be kept separately for the time being, Here. If you like to be more up to date with the Newest Marlin features, I have all my most recent updates here.

Right now flashing Marlin 2. Other than that follow the directions below. Use this link for Archim series or Archim Dual boards for now. In case you have never used GitHub, the first drop down lets you select the firmware version you want.

The next step is download the firmware you selected. All versions have the full graphic LCD enabled. I can add links to all of these if it is still unclear. If I enable this by default we would be working with the Z max unless otherwise specified in the gcode.

Might be a good thing. This will help easily identify what firmware people are using and if there are ever issues we can flag it. Ultimachine Boards. The picture below is an example of a board running smoothieware. Many other boards are available. This is just me getting my feet wet and there are a lot of other options you can add to the file. Config for smoothie boards. More info here. The picture below is an example of a board running GRBL.

First board I ever bought…. GitHub Firmware If you like to be more up to date with the Newest Marlin features, I have all my most recent updates here.Of course you can go smaller. This CNC router can handle any length within reasonthe Y direction is only bound by your table length.

Calculator for table, rail, and belt lengths in inches. Calculator for table, rail, and belt lengths in Millimeters. The VacDuct, sits inside the router clamp body to separate the router exhaust and the vacuum intake.

When setting the tension for the X Mounts after attaching them to the plate set the tension for each mount individually. An easy way is to use the Z rail and run it through each one, very light tension, you might not even need to add any, the mounts are interference fit. If not check these three points. There should be a gap of a few millimeters equally on each side of the corners to the XZ Main.

These parts can alter the Z rail angles so care is needed. They do not need to be extremely tight, a little pressure goes a long way. This is how these couplers should be used. The coupler should not be compressed, if anything a little stretch to make sure the lead screw is in contact with the stepper shaft. This prevents bouncing.

The lead screw should be only inserted as far as the coupler bottom collar. This lets the stepper shaft and lead screw to move for any minor misalignment.

Seat the grub screws on the shaft trying to get the straightest connection possible. If you hit an edge it will get wonky just give it a little turn and try again. On the stepper shaft tighten the flat screw first then the one that hits the round surface. Do not forget to lube the Z lead screws. If your rails are crooked this is where to check. It is best not to tighten the M3 screws all the way on the T8 nuts. This allows for a touch of misalignment and smoother Z action. This will help keep a reasonable arc in the cable tie at the belt end provided you use the clasp end as shown and the belt flat.

The other end of the cable tie connection is rounded internally on all printed parts with a similar arc.Marlin 2. Is there anyone here that knows how to setup Marlin 2. My goal is to upgrade my printer, laser and cnc to all use the same series controller boards. The printer is a corexy type and uses a Rumba controller. The laser uses a Ramps 1. Thank you. Edited 1 time s. Reply Quote.

But you can look at there information here. Right now I have 4 different machines. I use 3 different versions of firmware. I would like to condense all this to 1 firmware and 1 controller type. The V1 Engineering projects are using many different controllers and Marlin 2. I think that the question then becomes: Why go with one controller and firmware?


Okay, reducing the kinds of parts I can understand, but why the firmware? You'll need to maintain different compiles of Marlin anyway for different machines. I needed different compiles of Marlin for 2 printers that were nearly identical, If I had uploaded the wrong build of Marlin to the printer, it would have caused problems. RRF on the Duet is a little better, since local config files are easier to swap out. I don't see that this is really going to make your life that much easier.

So, since I assume that the goal is to make life easier, I'd keep GRBL where it's the best choice, and use what's the best choice for the hardware that you have.Install the Arduino software and its drivers before you plug in your control board. You might need its included drivers, so it is best to let them install.

MAC User? If you bought a system from me the firmware is pre-loaded and you do not need to make any changes. Marlin is the firmware currently used and it is pre-flashed on the control board included in the kit download the pre-configured files here. Never plug or unplug anything into the control board while there is any power, usb or power plug! Move your gantry to the center of your build space and make sure the z axis is roughly centered in its travel. With all the motors plugged in, plug in the USB cable and the power to the control board and hit connect in the upper left corner of repetier, it should take a few seconds and turn green to indicate it is connected.

If you have a series flashed board no end stops are needed. You can now use the control in the manual tab to move the machine. The arrows allow for. Start small 1 mm at a time. The arrows should move it in that direction. Z positive Z up arrow moves the z axis upmeaning the tool away from the work surface. Power back up and test again. Now that your machine can talk to your computer you need to be able to control it.

You can either use an lcd screen or control software. For the beginners software is usually easier to learn than the LCD screen. This can move the machine along any of the three axis and can also send gcode generated in any program estlcam, slic3r, Image2Gcode, Fusion, etc.

Repetier-Host is an easy program to use, here is a basic set up. Again for the beginners, start with repetier-host not server. Now the machine should be moving around and once you finally get bored of manually moving it around it is time to put it to work.

The infamous Crown… Follow the Basic instructions on how to actually use the machine. Test code available at the bottom of that page. If you ask for help I will ask about your crown test. Now the machine can draw pictures it is time to get it dirty. When you are ready to try and cut something, here are some Intermediate instructions.

This page has all sorts of things to try. Getting Started First Use Install the Arduino software and its drivers before you plug in your control board. Firmware If you bought a system from me the firmware is pre-loaded and you do not need to make any changes.

Testing Never plug or unplug anything into the control board while there is any power, usb or power plug! Control Software Now that your machine can talk to your computer you need to be able to control it. Step 1 — First Use Now the machine should be moving around and once you finally get bored of manually moving it around it is time to put it to work. Step 2 — Getting dirty Now the machine can draw pictures it is time to get it dirty. Step 3 — Getting Creative This page has all sorts of things to try.I set up the electronics with two Y axis motors and 2 Y axis stepper drivers for extra torque.

In the video, the motors are already prepared to have 4 connections, but you'll probably have to connect the 8 wires together in the correct order so that the driver chips can control them. Technically speaking, this means wiring a unipolar stepper motor in a bipolar configuration.

The first image shows the diagram of the motor coils and wires from the data sheet. I've drawn red lines between the wires I joined together, and the blue lines show the wires that you need to solder to the 4-wire motor cable. The colour codes of the wires coming from your motors will probably be different, but the aim is to connect each pair of coils together as shown in the diagram. The second image shows the most common 6 - wire stepper configuration.

In this case, you'd ignore the 2 wires that I've coloured orange, which are connected to the middle 2 pins of each pair of coils. If you can't find a datasheet for your motors, it is possible to work out which wire is which using a multimeter, but I won't cover that here because I don't want to overload this Instructable with details. I could have cut those wires back a bit before soldering them, to make the wiring neater.

I used electrical tape plus heatshrink, but it's better to use heatshrink of the correct size instead. Strip the end of the green wire, and screw that into one of the terminals with a black wire. That's essential to turn the ATX on. Cut the rest of the wires back so that there's no exposed metal, and tape or cable tie them out of the way.

Plug in the ATX and turn it on. For dual Y belts, this should be set to true. Upload Marlin to the Taurino. You should be able to connect to the Taurino with any errors. Plug them into the X, Y, Z, and E1 slots. Turn all the trimpots all the way down all the way clockwise.

Stick the heatsinks on to the driver chips. The motor probably won't move. If your motors are all the same model, copy the wiring order you found to all the motor plugs.

Once the motors turn, you can play with the feedrate in Pronterface to find out how fast you can make them turn. Don't turn up the trimpots on the stepper drivers yet, though.

You should connect a fan first. Marlin should report the status of the endstops. Close Pronterface and upload Marlin to the Arduino again. Press the Y home button in Pronterface.

The Y motor should start to turn. Then insert the aluminium foil into the gap of the Y-min endstop. The Y motor should reverse direction.

Remove the aluminium foil from the gap, then put it back in again. The Y motor should now stop. That's it! The electronics are ready to install in your CNC router or milling machine. Once they're installed, and you arrange a fan to cool the stepper drivers, you can tune the motors up a bit more. Did you use this instructable in your classroom? Add a Teacher Note to share how you incorporated it into your lesson.I used ascii-xfr with a ms line delay:.

In particular, having the Z axis homing downward is just plain dumb. This entry was posted onand is filed under Machine Shop.

Marlin The So if you have read this already no changes but having to link to it several times a day I need to bump this back up.

If you don't want to read everything below. Due to some awesome software updates our machines should now run so much more reliably and accurately. Mark walks through every step on how he does a tool change and some of the other methods out there. I really appreciate his perspective.

No electrical endstops or z probes needed. There are so many ways to change a tool, this is his method and reasoning behind it.

Choosing an Image Grey scale images do not translate well on to mirrors because either the surface is reflective or it is not. So straight 2 color images with no gradients are best. Just plain old black and white. The higher the resolution the sharper the edges Christian Knuell has outdone himself and has began the porting of his firmware over to the Ramps stack that is most commonly used with the Mostly Printed CNC.

This means you can now use his software instead of repetier-host if you so desire! Lend a hand, give it a This is an intermediate walk through on 2. You should have a firm grasp on the basics before trying this.

This is how to manually set up a 2. This software seems to do everything I want. It also seems to be translated into every language I've ever heard of, if not you can add translations in the software. The installer is in German I think but the Assembly of my all metal version of the Mk8 import extruder Click on the images for more detail. I ship these partially assembled.

These are not assembled by me so a few extra minutes starting from scratch can save a lot of headaches in the end. Start by screwing the Click on the printer settings gears in the upper right hand area of Repetier.
