    I'm using a 750W PSU to power both the RAMPS board and the Pi3. Using the 5v continuous power line (purple) I'm able to keep the Pi on all the time, and using the PWR ON line coming out of the PSU, I've attached that to the RAMPS board and I can now use the M80/81 commands to turn on/off the motors using the software. Using AstroPrint right now as my slicer....very happy with it so far.

    what thickness is the bed? Did you machine it? I made a 400*400 and got a 6mm sheet of aluminum as bed but it wasn't perfect flat. I am thinking to make it from glass. I also notice you changed the Z axis Delrin wheel brackets with aluminum and add a second. Did you had issues with Z axis from weight and made these modifications? Should i add another?

    I'm using a jig plate. It's 15 inches square and 1/4 inch thick from Cast Aluminum Tool & Jig Plate (ATP 5) | Midwest Steel & Aluminum
    I would definitely add the front bar. It greatly improved the stability of the build plate after I attached it to the front. Also, I added a pulley system that connects both z axis motors so they cannot get out of sync. I'll attach a pic of that so you can see how I did it

    Mostly the aluminium extrusions I need to buy for 30*30*50 and the leadscrew? Besides that and belts, I am guessing everything else stays pretty much the same?

    Have you downloaded the d-bot build instructions? That's a very good place to start. I bought 4 pieces of 20x40x100mm for the vertical pieces and everything was 500mm. The 2 leadscrews I purchased are 8mmx500mm

    Hi,
    Your machine looks fantastic ! :thumbsup:
    so all extrusions are 500mm in length ? or do I add 200mm and 100mm to the v-slot rail sizes in the D-Bot build guide ?

    I do not use autolevel anymore. I just make sure the bed is level manually.
