    Thank you for your reply. I will try an older version of the IDE and see how that goes. I am also checking out your other instructable. Thank you for posting this though. If it weren't for instructables and other people I would be lost with the arduino. I appreciate the time you've taken to help others out.

  • RF 315/433 MHz Transmitter-receiver Module and Arduino

    I am getting an error saying that vw_set..... was not declared... I know the library is available as it showing in the IDE examples as well as libraries... I'm baffled.People are asking about longer range... The RF24 is a good transceiver for long range. They carry quite a few channels and have been proven to like 10Km..

  • How to run a brushless motor ESC with Arduino

    #include Servo ESC1; The above line doesn't compile. I am tinkering with it now to see what I can come up with.

    I noticed this post is 2 years old. What did you end up going with? If you can get ahold of something like the drive system in one of those rotozip tools, They have the speed, torque (thru gears) and they are dc so that's a nice advantage. I prefer to keep as much DC as possible so as to avoid getting zapped.

    Miniature Laser Engraving

    How do you plan to run GRBL on this machine? I have been thinking about replacing the board with an arduino uno so that I can add a cooling fan, a work light, and maybe even another axis. I have the arduino uno and the cnc shield. I've started building one from scratch but I threw that project out the window and replaced it with one that's built out of a flatbed scanner and a printer head drive assy. I haven't finished this yet, but when done it will be able to "engrave" 10" wide (X) by 14" long (Y)

    When I ordered mine, I didn't know anything about CNC of any kind other than I thought it was really fascinating. Now I've modified my carver so that it's got manual seek buttons. It took about a week of reading and watching youtube to figure out how exactly everything works.. but the day I pulled it out of the box, I printed off about 10 items. My wife and I used it this year to make christmas ornaments out of wood. I love it. It's as simple as... select an image, drag it to the carver software, send to printer, check alignment/ centering of item then select your desired burn time, and hit start... It's very easy.

    They don't really use end stop. They tend to overrun bad if you move the axis prior to start up. They do a homing cycle upon start up, then once running they only move x steps in either direction. I hope this helps. I did manage to add 2 buttons on the empty ports of the board so that I can have manual seeking. This helps when loading and unloading material from the bed. The neje dk8 is enclosed with such small openings to reach thru.
