The Frequency or number of pulses over certain time period dictates the overall speed that can be gained from the drives/motors for a certain amount of micro stepping set in the drives. If the pulse signals generated are poor quality then the drives don't ilke this and because the drives control the motors this passes down the line so poor performance.Įqualy the frequency of the signal plays a important role in the performance. Most common is the Parallel port because it's free and part of most PC's.īecause the Drives are controlled with electrical pulses the quality and frequency of these pulses plays an important role in how the machine performs. Now how these signals are produced and recieved can be done in a few ways. They also control External devices like Vacuum, coolant etc using general Outputs. They also monitor incoming signals for things like Limit switches, E-stop etc.

The Machine Control software ie: Mach3, linux CnC etc all do the same thing in they convert G-code files into electrical output pulse signals. It all starts at the PC.? We need some way to communicate with the electrical components that make up the machine ie: Drives.

I got the driver and motor part thats no problem.Ok Well there's No such thing as Dummies around here just the Un-enlighted.!!. If you got the time i would appreciate the "CNC Electronics for dummies "version of it all. If you want to go my route, I'd say buyĪnd either build a toroidal linear psu (should be slightly better) or buy a 70-72vdc switched psu with some overhead (should be good enough, cheaper and easier). Get a motion controller, get digital drives. I realise I'm rambling a bit here, but perhaps I got my point across.
Doing that from a printer port would require an expensive bob, and you'd still be limited in the amount of pins on your db25. Less than an hour ago, I added a crosshair laser to my machine, took me 30 seconds to hook it up to one of the relays on my plcm-e4 and I could control it from mach3. You get smoother and faster motors from the clean pulses, you can use a modern computer (even a laptop) to run the machine, you can use a 100m long ethernet cable instead of a 1.8m parallell cable. No idea if it's any good, but it should make the power supply slightly cheaper and simpler.Īs for using a motion controller, I'd recommend getting one. Also, I've seen a version called am882h, that takes ac input. However, I haven't heard of anyone driving a slightly binding, quite heavy carriage at 15000mm/min at only 36 volts. I haven't tried the geckos, but from what I've heard people are quite pleased with them.

Right now, I'm about to throw the old drivers in the trash and get 3 more am882's. This time (putting the new stepper on the y-axis), I went for a together with an am882 from aliexpress. When I built a new machine, I added another stepper, for the dual x-axis setup. I started buying together with mid range inductance 3nm steppers. Yet everyone, including me, think themselves above this one fundamental rule.

Maybe I’ll update this article later on, if and when I have more to share.I'll start with reiterating the same advice pretty much everyone that has built something gives others: Buying cheap stuff usually ends up costing more than buying more expensive stuff. I plan to use it as a second Y driver, so each motor has a dedicated driver, but at this time I’m running both Y-axis motors on 1 output. I currently use all of this in the most basic of ways (no spindle control, no limit switches, even no emergency stop atm, but don’t worry, that’ll be my first priority!), but I hope to implement more features as I get comfortable with it.Ībove there are 4 stepper cables attached, but I am currently not using the 4th axis. Other than that, not much to say, really… I am still learning as I go. Below is a picture of one of these connectors opened, but my vendor already matched them to my motors and shipped them all closed up and ready. I also bought the very user-friendly EZ connectors, which feature a potentiometer instead of having to solder the appropriate resistor. The sad part is that my electronics enclosure is already obsolete… It is supposed to be very stable, and the obvious choice for the control software – Mach3 – is well-documented with more functionality than’t I’ll ever care to learn.

It was a logical choice to upgrade considering the much sturdier motors I now have, which draw a considerable amount of current, too much for the Gshield to handle. I actually almost forgot to write a little something about maybe one of the more substantial yet invisible upgrades: I ditched the whole Arduino/Gshield setup and bought a real CNC controller: the well-known and praised Gecko G540.
