WinCNC, UCCNC or Centroid Acorn

Right now, having started looking into this, I would lean towards the UC100 and their software at this time.


I would recommend the UC400ETH. Ethernet has far better noise immunity than USB, and there ethernet controllers are more powerful. The UC100 has been around close to 10 years, while the UC400ETH is fairly new. The price difference is only about $25 or so I think.

Let me tell ya, the folks who provide this stuff do not help to overcome that resistance.

Here is a for instance: I use a Gecko G540 and a smooth stepper (usb). <the G540 works great with Acorn,, we even have G540 auto config button in the setup wizard>>>

From reading through the techo babble I have no idea if any of their controllers are compatible or not, right down to plug level. Software I have no issue with until I read about one of them saying that their "free software" will only run programs up to 50Kb. These days that is a joke for anyone running anything except mechanical parts in the most rudimentary manner possible. One of them, for a mere $140 more will allow unlimited program size. < the Free version of Acorn CNC12 software is mostly for anyone can use it to see if it works for them, (think try before you buy) and the Pro version gets you a lot more than Unlimited file size, the list is very long of the Pro cnc features you get for $140.. check out the Acorn page for the highlights...most vectric users will benefit greatly just from the G code smoothing Pre processing feature that lofts arcs thru short vector gcode..>>> In addition to that one of them requires a touch screen monitor to run. The costs keep adding up. < Acorn does not require a touch screen, mouse and keyboard work just fine.. Acorn is touch screen compatible..>>

There are some drive controls that are pretty ubiquitous, Gecko drives being one of them. It would be handy if in addition to writing techno babble for the techies they wrote something like:

"If you are using a "________" drive control then you will need to purchase A,B and C. << this is exactly what we have done..see below>>

The idea is to make this easy for people just like me. I am not stupid, but I have better things to do than reading up on the latest chip developments, scouring long lists of specs that mean nothing to the average user. Sure, those things are important, but some of these folks need to provide the "Here is how you do it for Dummies." << that is exactly what we are doing with Acorn.. check out these resources. links below..step by step videos and easy wiring schematics..>>

https://www.centroidcnc.com/centroid_di ... guide.html


check out all the drives that we have created easy to follow hook up schematics for! all these schematics correspond to a radio button in the Acorn setup Wizard, simple wire drive to Acorn according to the schematic and press the Corresponding radio button and you are turning motors in minutes.

Thanks Gerry for that info.

Let's see if we can get back to the original discussion.

How do you rate the motion of the UC400eth? I think earlier you wrote that it was decreasing run time significantly, like 20% or so. I noticed that the CNCDrive folks are not particular about computer horsepower which is a good thing in my book.

BTW, have you been reading my mind? One of things I wish I had in my current setup is multiple park positions available from on screen. When I am working with the vise I generally like to have the machine move a bit behind the vise for parking, but at the end of the day I like to park the machine with the head way back. That was a good call on your Screenset for the UCCNC.

This whole thing may tie in with the computer replacement.

I am thinking that all I will need to do is connect the cable from the UC400eth to the back of the G540 and plug the UC400eth into the ethernet connection and be good to go. Sure hope so, because if there is one thing I do not like doing is wiring.

As I mentioned before, there is one minor issue, but if your machine has decent accel rates, you should find it to be much better than Mach3. While it may not be faster running identical code, it will generally allow you to run at faster speeds. The vast majority of people that go from Mach3 to UCCNC find it to be much better. And with all CNC Drive controllers, you can still run Mach3 if you wanted to , as they support UCCNC, Mach3, and Mach4. (Mach4 support may be limited).
Here's a comparison between UCCNC and Mach3 doing 3D carving. https://www.youtube.com/watch?v=UJ8NM1MVFdM

Again, the main thing you need regarding PC support is OpenGL. The onboard graphics of most modern Intel processors should be fine, though.

I think you'll need a small 12V or 24V power supply for the UC400ETH, but yes, just plug the G540 into it. And you have the option of adding a second breakout board if you want/need more I/O.

isla, i am less than a year new to this cnc router world but rely on my machines for my income. we create custom wood signage. after many many random issues resulting in scrap ,with mach 3 on both machines, i have decided to try a new approach hoping to reach a higher level of reliability, repeat ability and just plain quality. a local here in tampa bay gave me the sales pitch for centroid and i did much research on my own afterwards. i am thinking that i will upgrade one machine first to the centroid acorn system and see how it works out before adding to the other machine. both are diy currently using mach 3 with smooth stepper. is there support online that would assist in the change over? thanks,db

Yes there is. The Centroid Acorn Forum: http://centroidcncforum.com/viewforum.p ... 1270f1249a
There have been over 2000 guys that are using the Centroid controller via the Acorn platform, the majority have swapped from Mach3, but the user base has experience from dozens of other controllers.

If you wish to shortcut the learning curve and reduce downtime, as a Centroid approved system builder, I can provide you with a turnkey control system. More info, pricing and available options for the "Basic" system is here: http://centroidcncforum.com/viewtopic.p ... 7&start=10

The basic system is a open loop stepper controller that is tested, calibrated and setup including a CNC-PC. Systems with closed loop steppers and Teknic ClearPath servos are also available.
