  • 3D Printed Laser XY Scanner - Draw, Cut, Engrave, or Scan

    PLEASE everybody that builds this design Please be very careful and pay close attention to where the beam will exit this device...THIS IS VERY DANGEROUS This needs a shield completley around it BEFORE you turn it on

    someone out there please rework the code to use laserGRBL and this will be a very good project but now all you can do is draw a square....and how do you calibrate the number of steps per mm or inch if the target can move...so fix the target at 12 to18 inches and then this will be great as you will be able to use any bitmap to burn or cut

    Please tell me WHY Autodesk does not or can not explain the use of this app as you did...now I understand how it works and what to do to use it(if it does not crash)...This is a fantastic tutorial and they Autodesk should PAY you very well to use this tutorial.

    This is a GREAT idea ,when I was in college years ago I built a box like this only we did not have arduino we used 8080 processor a hex keyboard and wirewraped logic 74XX ttl to build circuits and no we did not have a PC and no internet....but check us out today...WOW we have come a long way in a short time.

  • 3D Printed Laser XY Scanner - Draw, Cut, Engrave, or Scan

    I want this to use grbl1.1 and laser grbl to drive it howeverI have one question I must put in a Xand Y number of steps per mm, now I want to mount this unit 12 inches above the cut table is there a formula for determining number of steps per mm or do I enter what I beleve to be accurate numbers or just mount the device and experimatally determine the correct number of steps for a given line length at a given distance from work table?

    2W Arduino Laser Engraver/Cutter

    PLEASE for your own EYES....these things are nothing to play around with one wrong move and you are BLIND or someone walks into the room and they are blind...Put your hand in the wrong place and a hole is drilled into your hand oh no blood but it hurts real bad.Read first ,Learn all the safety rules first than take the big step.

    you need to take a serious look at laserGRBL....I use it with a small laser cutter and it works perfect and the arduino nano with two step sticks is a dream now I am working on a 2 foot x 6 foot xy table I just acquired the guide rods.

    in a plotter it is pen up/down...using grbl it is spindle on/off check the grbl pinout

    with a working pen plotter just replace the pen with a blade holder and use autocad for drawing your designs/practice with the pen first.

    use the code for spindel on/off and connect the up/down mechanism to the respective pins

    Mine works perfect ...It takes time and patience to assemble and align this machine...recomended for people with cnc and or pen plotter experience or some mechanical or electronics assembly experience

    The Arduino / TFT LCD Connection

    #1 you need a data sheet for the display and pinout and the i/o board attached to the cable.Than before you buy check for a driver for this chip Raydium/RM69071.if no driver lib are you able to write one and do you have the necessary tools to work on this scale to wire it up ..if you answer no than search for an arduino ready product.WCH

    hooking up and adding a lib is no piece of cake insure the screen you buy is arduino ready and sold by a reputable shop with step by step directions...WCH

    It depends on the source drawing ,most of the stuff I do is lines an circles, however I do use F-engrave to convert bmp or jpeg ect to dfx,I have experimented with the drawing apps to mod a line drawing to dots,alot of clacking but it works ,one difference is my machine uses a stepper drive for the z axis whereby yours uses a solonide....
