    No problem! I can see now, that of course not everyone is familiar with Fusion 360... I look forward to see your result!Best regards,Mogens

    Low Budget CNC

    I have just added drawings showing the MDF parts with measurements. Hope that helps!

    I paid around 200 USD in parts for this machine. That includes everything, also the dremel (not a genuine dremel), controller and PSU.

    No, why should it be that? Based on the parts I have done with it, I have gotten an accuracy that is at least 1mm.

    Hi, The idea is that you should be able to build it yourself quite easily. It is not available for purchase :)

    Hi,You should open the file in the provided link in fusion 360 (step 2). In there you can measure everything out :)Question 2 I don't understand?Software is just plain GRBL, and settings is shown in Step 4. There is not much programming to it.

    Hi! I can't see any problem in just extending the different axes according to your needs. So just extend the tubes, threaded rods and MDF parts :)

    Hi!The bearings are not attached to the u-bolts. But they stay where they are, since the u-bolts sits tight against the pipes. The bearings are unable to move to the sides when everything is tightened.The alignment has not been a problem - everything runs smooth. I have built 10 of these machines in the current design revision, to ensure that the design was okay. Essentially it all comes down to how much effort is put into building the machine (ensuring that all measurements are kept within a small margin). The machine design here is a bit forgiving though. The MDF is a bit soft, so some of the misalignment will be removed through this.

    Yeah, it's incredible how much power you can get for almost nothing these days. I would hesitate a bit if I had to use gate logic for controlling a machine like this! It's really great that so many put so much effort in the open source GRBL firmware for these small microprocessors.

    Thanks! - I have 1.25mm/rev on an M8 threaded rod, 200 steps is one revolution on a full step stepper, I use 1/16 microstepping giving: 200*16/1.25 = 2560 steps/mm

    Hi again! Just got a friend of mine to open the STEP file in Rhinoceros, and it opened up fine. It's a bit heavy, but that's because it's a combined model. But if you have trouble, try out Fusion 360. Unfortunately I don't know any with a SolidWorks licens, so could not try that one out for you.

    Hi! Thanks for the support!You can use something called img2gcode (google it), for converting an image to gcode. It has some settings enabling you to cut out the dark areas.The machine should be able to handle a reasonable size trim router. If the machine gets wobbly, you may have to offer some speed. But I believe a larger tool than a dremel can be used without causing to much of an issue.

    Hi! I am not the creator of this Robot Arm design. Unfortunately I can't remember where I got it from, since it's maybe 9-10 years since I found it. I have a dxf file that I once downloaded. It was open source, but I can't give credit to the creator for the reason just stated.

    Hi! I did some routing in 1mm aluminium. The important thing is to get the right spindle rpm and the right bit. The threaded rod is just regular 8mm from the hardware store. Best regards, Mogens

    Hi!I have just added a couple of fotos, showing what the machine can do. Unfortunately the machine is sold, so I can't even make new examples to show. But I have been doing engraving in MDF, which it also did very well - just don't have any pictures of it.
