Adafruit Motor Shield 1,7a
@ Abbas Kagdi Your project spec is now almost complete. Now I also know your motor knowledge and skills. I started getting serious playing motor controller only a couple of months ago. Some years back I used Arduino Decimilla (My first Arduino) with L293D (which your Adafruit motor driver uses) etc. I also once messed around with steppers and servos. Now I am into L298N and TB6612FNG.
I also would like to refresh my Arduino motor projects to Rpi. Perhaps I can answer your question from my couple of months hobbyist experience.–Apr 10 at 1:44.
I am trying to control a NEMA17 stepper using the V2 motor shield. The Adafruit shield draws over 1.7A (I have limited the current to 1.7A, but it wants to draw more!) during operation, whereas the Arduino motor shield only draws around 800mA using the same stepper.
- V1: They, from Adafruit, design for a full-featured motor shield that will be able to power many simple to medium-complexity projects. 2 connections for 5V hobby servos connected to.
- I'm trying to control a 42byg stepper motor (using the Adafruit motor shield v2.3). I've read that this motor is not compatible with the motor shield. Is there anything else from Adafruit that would help to control this type of stepper motor, or do I need to start looking for new motors? The motors came as part of a MakeBlock kit, but I've.

To make gcode files that are compatible with this cnc machine you have to use the Inkscape.Inkscape is professional quality vector graphics software which runs on Windows, Mac OS X and Linux. It is used by design professionals and hobbyists worldwide, for creating a wide variety of graphics such as illustrations, icons, logos, diagrams, maps and web graphics. Inkscape uses the W3C open standard SVG (Scalable Vector Graphics) as its native format, and is free and open-source software. Download and install Inkscape from:(Important: download 0.48.5 version)Now you need to install an Add-on that enables the export images to gcode files. This add on can be found here with installation notes.Setup Inkscape for first use Open the Inkscape, go to File menu and click 'Document Properties'. See the 1st image above and make the changes, make sure to change first to 'cm'.
Now close this window. We will use the area within 4 to 8 cm. See the 2nd image above. How to print texts Put text, change font to Times New Roman and size to 22. Now click on cursor icon and center the text like the 3rd image above.
Select Path from menu and 'Object to Path'. How to print images This is more difficult than texts. Images must have a transparent background. Drag and drop the arduino logo image (download it from files) in Inkscape. Click ok to the next window. Now you have to re-size the image to fit our printing area, see the 4th image above.
Click Path from menu and 'Trace Bitmap'. Make changes as the 5th image above. Click ok and close the window. Now, move the gray scale image, and delete the color one behind it. Move the grey image to the correct place again and click from Path menu 'Object to path'. The 6th image above show how to delete image outline. Export as gcode Final, go to file menu, click save as and select.gcode.
Click ok on next window. Use the gctrl.pde app to print the gcode file on your new Arduino CNC Plotter! I will make a video on next days about this procedure because it's little complicated. It took me a lot of time to understand how it's working. Now we are ready to print our first image! To do this we will use the gctrl. This program sends 'gcode' images to the cnc plotter.What is gcode?
Gcode is a file with X,Y and Z coordinates. Header of this file is set to: M300 S30.00 (Servo down) G1 X10.00 Y10.00 F2500.00 G1 X20.00 Y10.00 F2500.00 M300 S50.00 (Servo up)Click the 'play' icon/button to start the program.Download gctrl for Windows:Click First time to ' p ' to select Port number for Arduinoand click to ' g ' to select Gcode file. Hi, very, very good project, I see that many people have been successful.I have uploaded TestXAxisCNCPlotter and Y, and my engines have good movement.I have a problem with gctrl.pde and gctrl.exe, but I do not know why.
My engines have no movement with gctrl. Select the serial port (OK), use the arrows and no movement, load a gcode image with (G) and no movement. I do not know where the problem is.You help me? Thank youMy beta-CNC without Arduino, only router with OpenWRT and L293 driver. Does not interpret GCODE yet:https://www.youtube.com/watch?v=16uzCy-xsO0.
