    Hi I am Matt from Hull UK. I am looking to build my first MPCNC. Its going to be a slow process as I want to build it with my 13yr old son, as a way of getting him to put the Xbox controller down and learn some old fashioned “hands-on” building experience.

     

    I will be doing the Burly design, as big as possible to allow for the most possibility of uses, however – may build a low rider later on also for huge sheets.

     

    My questions are as follows:

     

    1.  What is the maximum size that I can build an MPCNC before stability and accuracy becomes an issue? I will be using 25.4mm Stainless tube for my build-so will be stronger that the US conduit version.
    2. I want to use an MKS Gen L board, purely as I already have one to hand. Does anyone have any info on how to put the code on it-as in what differs from this sites instructions for the Rambo boards?
    3. I was originally going to rob some steppers off an old 3d printer-but unsure what Oz ratings they were. But I found these on amazon, 84oz and 2A: https://www.amazon.co.uk/STEPPERONLINE-Stepper-Connector-Printer-Extruder/dp/B077X9HTNX/ref=sr_1_2?keywords=stepperonline+5pcs&qid=1563358255&s=gateway&sr=8-2

    I presume these would work fine?

    4. I want to use a spindle rather than router-purely for the quieter operation. There are many available in the 500W catagory- does anyone have any recommendations? Preferably one available in UK if possible-but will ship from China if need be.

     

    Thanks in advance-I am sure many more questions will follow!

    Awesome, I can get the friends kids to pay more attention calling it a robot.

    1-Depends on what you consider stable and accurate. Some people are okay with a 1/16″ some call it a POS if it is worse than 0.00001″. There is not a magic number where it is just bad, the longer the looser.

    2-It needs firmware to match the build you make, looks like you plan on sourcing everything so you will need to match what you buy, dual requires more changes.

    3-Sure, a bit overkill but fine if your drivers can handle it.

    4-Vacs are just as loud as a router, but the 500W imports are hit or miss. You need hearing protection either way.

    the mks gen l board uses the ramps firmware, either standard or dual endstops and is just installed with arduino IDE.

    and those are the same steppers i have, so will work fine.
