This video is a tutorial showing you how you can use LinuxCNC to control a CNC router. It's free software that I did use to make parts for RC aeroplanes and drones. I've used the OX CNC router from OpenBuilds supplied as a kit from Ooznest. But it should work with most CNC routers
It's a long video so I've included the section you can jump to

LinuxCNC is a great solution and the Mesa Ethernet adapter is probably the best option for modern computers.

One of my 3D printers( a delta) runs MachineKit via a CRAMPS board. I've heard LinuxCNC has lots of features which can really help fine tune even a cheap CNC well. I appreciate the effort you put into this.

I have just bought one and it says on the control box it will only work with a desktop PC - despite the photo on the advert showing it connected to a laptop. It came with a USB (computer end) to 25 pin parallel port (control box end) adaptor lead. I have an old laptop with Windows 7 64 bit installed and I'd like to use it with LinuxCNC. Before I mess anything up, could you advise me please?

@rckeith 4 жыл бұрын

Hi Bob, LinuxCNC won't work with USB. if you want to stay with USB then you will need to use Mach3 or the Arduino based GRBL controller. LinuxCNC works well with the old parallel port and doesn't require a powerful computer. I run mine on old Dell Desktops that are getting on for 10 years old. Mach3 will even run on them. It sounds like you have a copy of the UCCNC100 adapter and that will only work with Mach3. Drop me an email with a few pics and I'll be able to give you a better answer. Keith

I installed linuxcnc on my computer. You mention to stress the computer when running the latency test, but then say not to have it connected to the internet. So how do you know how much stress to put it under? I did not know how to run other programs while running the latency test but the ones you mentioned. I put 2 and 3 sets of the gears running and got somewhere in the neighborhood of 42,000. Then I did it with 2 gears running a and then KZfaq trying to get a video up. KZfaq never completely installed within 1/2 hour. But, the number went to 50750 right away and stayed there for the full 30 minutes. How much to stress it? This was a windows machine that I loaded linuxcnc on top of it. Thank again for the videos. I got the ebook, but it was funny that it never did come through to my wife's. Hopefully I will completely finish my wire cutter and see how and or if I can get it to work with linuxcnc. My driver board is a old mm2001 board. I am looking to use the cat cables as you have for the stepper. Thanks

@rckeith 6 жыл бұрын

Hi Elson Both are very good , Mach3 is more widely used but can look a bit complicated. LinuxCNC is still being developed unlike Mach3. If you already have Mach3 and it does what you need, then probably no point in changing over. I prefer LinuxCNC for my CNC foam cutter because the display show the tool paths better for 4 axis. I don't think one is better than the other they both work well.

I am looking without success for info to calibrate axis with a measuring device to actual distance traveled,not theoretical values.As is present in mach3.

@rckeith 5 жыл бұрын

I used a digital caliper. Usually you can find a part on one of the axis you can use to measure against. Then set to zero and move a known distance say 20mm and me measure with the caliper. Can be a bit fiddley but I've used this method several times. Parts I've made have all been correct size. Hope that helps

@@rckeith yes but need calibrate 10mm and 100mm and more maximum tmm too. not only little dimension. because maybe have 10mm right and 500mm not right. calibration have big procres many dimension many axis. but after this no newer need do same again.

Try with ncstudio from China -> beautiful. Auto detect stepper motor, give you a perfect level for industry/hobby. Don't waste of your time and money like I was.

You can't destroy a hdd by partitionning, why have you said that ?

@rckeith 4 жыл бұрын

Yes, you're right a bit of a slip of the tongue. I meant to say run the risk of deleting an existing partition. What I was trying to warn of was if you already had a Windows partition then if you made a mistake you could delete it. Well spotted.👍

very easy can destroy if manually partition hard disk, only one click wrong and destroy all.

Just got a 3040 cnc machine...Can't get anything to work...super bummed. Followed these instructions over and over. Got the Debian software onto my computer but can't get any pull down menus...the ones you start to the setup page. Also the standalone xp 32 bit machine I am going to use to control my cnc, is now stuck in this debian mode. can't even turn it off properly. I have some experience with this stuff,,,and I am completely stuck. 500 dollar cnc just sits there doing nothing. Sure wish I would have done more research before buying this cnc.

Hi Todd, if you boot to live on the LinuxCNC ISO does it work on the menus. Did you try the latency test?

Hi, Todd sorry to hear you are having problems. Usually, when you partition a disk it overwrites whatever was there so its unlikely you'll get it back. Unless it's just the boot loader can't see windows partition and only Linux. The best option, in my opinion, is to use a dedicated disk. LinuxCNC doesn't need much so cheap 40GB would do, probably pick one up on eBay for a few dollars. If it's already put LinuxCNC on the disk then probably best to leave that on now. Stick with it I've helped a few guys out on CNC and they get very dishearted but when it works its a great feeling. You'll learn a lot as well which will be good for the future. If you want to contact me via my website www.rckeith.co.uk there's a contact page there. Good luck

need biggest motors if use fasten, lost easy steps if have too small motors. users say need minimum 450 oz torque motors but more have lot better, and perfect drivers handle lot biggest voltage too can use fasten, normal good cnc used 90 volt 6-8AMP drivers and motors, hobby users use lot less 40 volt less 6A motors. super expensive and fast have servomotors closed loop motors and drivers but cost 10-100x more than small size stepper motor cnc.
