    I am printing out my parts at the moment and am in the planning stages of my build. I am a little familiar with the RAMPS board since I have a 3D printer, my question is, will other controller boards work aside from the RAMPS board? Such as this board

    http://www.amazon.com/gp/product/B00PVF5SWE?ie=UTF8&ie=UTF8&keywords=RAMPS%201.4&qid=1442173517&ref_=sr_1_3&riskType=deactivatedCard&sr=8-3&successUpdatingPreference=1

    Or even this board which i was considering for a second 3d printer I was planning to build

    http://www.ebay.com/itm/Geeetech-GT2560-ATmega2560-control-board-Ramps-1-4-for-Reprap-Prusa-3D-Printer/121610665161?_trksid=p2047675.c100011.m1850&_trkparms=aid%3D222007%26algo%3DSIC.MBE%26ao%3D1%26asc%3D20140602152332%26meid%3D3aa933b974814c0389129d5cd9e88d07%26pid%3D100011%26rk%3D1%26rkt%3D10%26sd%3D121753274873

    As far as I can tell, those are still set up as RAMPS boards, just integrated with aruduino into a single board.

    Im still new and haven’t been able to do some full research on those other boards, from what I have read they look like they do the same thing I am just not sure

    Anthony is right. If you are looking for other boards for some reason all cnc boards will work. Start with the software you want to use and find the board it works best with. If you think ramps is missing something maybe I can clear that up for you, or let us know if you find a diamond in the rough.

    I’m planning to use a Smoothieboard clone called MKS Sbase running smoothieware firmware.

    There are some advantages that led me to want to use a smoothieboard, and some advantages to this clone over the standard smoothieboard, certnaly mor ethen I could list here, but here is the short version.
    first, smothieboard was designed to work with cnc. Making changes doesn’t require recompiling, they are simply text file changes in a config file. So for hacking around and experimenting its great. also the board has built in sd card adapter, usb and Ethernet (has a web interface and telnet). I plan to ultimately use it though internet to reduce possible interference issues with usb. The clone board I am using uses DRV8825 so it can handle up to 2.5a steppers and 16 or 32 micro steps (jumper changeable). Also I can, and will set it up so I am using a dedicated driver per stepper. it also includes spindle control and rpm loopback option for accurate speed control, which id intend to use if I go to an er11 or something down the road. and there is more.. best to go to the smoothieware sight if your intrigued.

    I became aware of smootheboard / smoothiewear when I retrofitted a 3d printer with it, and found how well it worked and how flexable it is..
    downside is the actual smoothieboard is about 150 bucks for a 5 driver board, but the clone board I am using can be had for under 100 bucks, I got mine for around 60 bucks. ymmv

    So it would be possible to use the printboard of an ultimaker Original plus? The fan output of mine didn’t work properly so the company sent me a new one and i didn’t have to sent back the old and ‘broken’ one. everything on it works perfectly except the fan output. But ofcoarse i don’t need that for a cnc machine.

    Yes I don’t see any problems. You will need to edit the firmware to match the ones on the marlin page. https://www.vicious1.com/marlin-firmware/

    Hi Innkeeper, how is your experience with mpcnc and the mks sbase smoothieboard clone?
    I’m plannig to build a mpcnc (my first cnc machine) and run it with this board.

    Interesting… That MKS sbase looks interesting only for the spindle control and rpm loopback. Integrated drivers do tend to be more reliable as (well better cooling due to larger board for heat dissipation). And simple accurate current setting.

    Well I tried the sainsmart 2in1 board. couldnt even get it to upload the firmware. had to download official ftdi drivers. Still no go. Read in the products description that the board is sold with an old bootloader and one needed to use arduino IDE older than 1.0.5 – ie 1.0.5 which is extremely ancient compared to current version 1.8.1. Tried to flash with ide 1.0.4 and still timed out on the upload.

    JUST DROPPED IT IN THE UPS RETURN BOX.

    InnKeeper can you share a link to this clone MKS Sbase ? Does it then run the same Marlin firmware? I am new to this and just getting started.

    You will be running smoothieware, on the sbase boards. There are a few that look similar, some run marlin, but the sbase runs smoothie.

    Ok. So i have the smoothieboard, mks v1.3, operating accurately.

    But i am having and issue with puddling i guess. Not sure which setting to change?

    I am thinking feed rate???

    See attached image. Any suggestions appreciated.

    alpha and beta steps are different, are you using different pulleys on each axis?

    I had to adjust the beta from 200 to 150 to get the y axis corrected. It printed fine in x axis and z axis be the y axis was 5mm off.

    I have been using the same ones, LOL. I think I ordered them from Vicious1.
    Pulley 16 Tooth GT2 – 2/9/16 – but that was for just one.

    Not sure.
