I have printers and scanners I can scavenge parts from. I don’t mind maintenance intensive stuff as long as maintenance is a couple dollars every two or three months. Anything beyond that (for the initial investment) is total bonus material, as far as I’m concerned. I want something I can use to muck up Radio Shack project boxes. And possibly explode on you, like one did to me. It will just bring you a headache (awful performance, awful documentation). *Do NOT get one of the cheap 3-axis Chinese boards for ~$40. Anything less and you’re probably in for poor performance in some regard, replacing parts down the line, and just a headache in general. TL DR: $500, a metal lathe, a drill press, and a table saw should get you going. If you want to see all the crap that can (and will) come up, take a look at my build (click my name above). The lathe is something I didn’t anticipate needing, but used ALL the time- turning down leadscrews, making bearing holders, and a bunch of other stuff. The mill or table saw is basically required to make all the square corners you’ll need- and that’s something that you REALLY shouldn’t *ahem* cut corners on. An existing mill would make life much easier as well. Oh, and if don’t have access to a metal lathe and drill press, you’re probably in for a bad time.

You can probably use an old PC power supply for a while, but at 12V you won’t be stepping very fast. I’d really recommend a BeagleBone Black (it has a hardware realtime unit, which is wonderful) with LinuxCNC for control, though you can get by with an old PC running LinuxCNC. You COULD start with solid mechanical parts, then put a dremel on there until you can afford a decent spindle just know that you WILL want to replace it. I know firsthand- I’ve tried to do everything cheap on my build, and have replaced just about everything in the process. If you cut corners on any of these parts, you WILL be replacing them down the line. You’ll also need a power supply, maybe $40.

“Cheap” is relative, of course it started out cheap in absolute terms, now I’m just going for cheap compared to what an equivalent commercial offering would be.īasically, you NEED good linear bearings ($50+/axis), a decent spindle ($100+, definitely NOT a dremel-type tool), and stepper drivers ($30+/axis)*. I normally don’t bother replying, but building and improving a cheap CNC machine has been my project for the past couple years. Posted in cnc hacks Tagged cnc, grbl, parallel port Post navigation He’s even made a daughter board for Start, Hold and Reset input buttons. As all great DIYers, has made his board and schematic files available for others to download. The design is single-sided which is great for home-brew PCBs.

The board has been created in Eagle PCB Software and milled out using CNC Router. However, there are other programs you can use to communicate with GRBL such as Universal G-Code Sender and GRBL Controller. is using a Raspberry Pi running GRBLweb to control his adapter board. This is a great solution for people needing to control a CNC Machine but do not have a parallel port available.

The GRBL code is responsible for taking the g-code commands sent from the computer, storing them in a buffer until they are ready to be converted to step and direction signals and sent to the CNC controller by way of the parallel port DB25 connector. So what do you do if your new fancy computer doesn’t have a parallel port but you still want to run your CNC Machine? Well, you are certainly not stuck as  has come up with a USB to Parallel Port Adapter solution specifically for CNC use.Ī cheap off-the-shelf USB to DB25 adapter may look like a good idea at first glance but they won’t work for a CNC application. If tinkering with CNC Machines is one of your hobbies then you are familiar with the parallel port interface being fairly popular for CNC control board connections. The parallel port’s demise is partially due to the invention of the USB standard. For our younger readers the parallel port is an interface standard used for bi-directional communication between a computer and a variety of peripherals.

With the continuing manufacture of new computers, there is a clear and obvious trend of the parallel port becoming less and less common.
