A project in the making.For a previous project, I wanted to be able to create PCB`s quickly and simply.I have tried many methods:. Toner Transfer (Iron Method). Photosensitive. Hand DrawingNone of these I found particularly inspiring or reliable.So after watching countless videos on Mini CNC machines, I have decided to build my own.I have been using Google SketchUp to design my parts and my AnyCubic Kossel to realize my designs.The design phase has been quite challenging for me, making sure each part has the correct dimensions and that each component will work with the rest of the project. Then you have to print it, and things very rarely go to plan, so you then need to tweak it. Re-model in SketchUp and Re-Print.

Arduino Uno Pcb Layout

PartsA list of the components brought are:. 6mm Steel Rod 1M cut into (2x 25 cm) (2x 40cm). Also purchased was a standard picture frame 5x7inch so I could use the glass as a bed, coincidentally the bed size I was aiming for was a half sheet of A4 paper which is 5x7inch.Oh, and you will need some MDF to use as a base. G-CodeSoftware side to enable an exported Gerber.GBL file from Fritzing to be translated into G-Code and sent to the Arduino via Serial comms, I am aware that there are many programs out there that will enable me to do this but there is a couple of issues I need to overcome.Most G-Code assumes that the Z Axis is a Stepper. Not true in my case, it's a servo. Now I do have GRBL V1.1 installed on the Arduino with the servo mod enabled but his poses another issue.

The Servo mod assumes that a M03 S1000 command will issue a PWM of 255 and a M03 S0 or M05 will issue a PWM of 0.But I want a M01 Z-1.0 to translate to PWM 255 and M01 Z1.0 to translate to PWM 0, So I have written a little utility in Visual Studio to replace any of the Gcodes listed below with the correct ones. Which spews the G-Code to my Arduino running GRBL and the CNC Shield.I have limit switches installed and this allows for homing.Below I will include links where you can grab the Zip which includes the Sketchup project and also the individual.STl files / Programs I made and used. I'm not sure if my G-Code Changer software will run just as an.EXE, as long as you have the.NET framework installed it should be fine. Any issues, give me a comment and I will try and publish it through VisualStudio.

Well, I want to make it very simple, I always work with arduino and the fact that you have tu use a full board on every proyect is not very economically efficient. So I decided to make a simple yet effective PCB to install the arduino and keep it working,Keep in mind that the PCB is supposed to work when you have already tested your circuit and program, no serial comunication or else, just a simple I/O pcb for the arduino in 5 x 3 cm.I Uploaded the Gerber file below, but I'll list the parts you need.1 -L78052 -10uF2 -22pF1 -16Mhz Crystal1 -AtMega 328 Attachments.
