UC CNC software 300eth and UB1

**A_Camera** · 19-03-2018

Q1

No, UCCNC is a complete software, you can use it as it is. You can download and install UCCNC and if you don't have a license it will run in demo mode but it will have all the functionality (except motion) and all the default screens. You can also install my probing tab window on top of UCCNC if you are interested in additional probing functions. There is a commercial screenset you can buy and install if you want to, but it is not necessary and I don't know the benefits of it, other than it has some additional probing functions.

Q2

The UC300ETH does not have Modbus interface connection, you have to buy a separate hardware for that. You can use a simple and cheap USB dongle, or buy a little more expensive Ethernet - Modbus interface, like I did. Works both ways. The UCCNC software has a Modbus plugin which is pretty advancaed, yet easy to configure but your VFD must support real Modbus, which many Chinese VFD's don't do. There is also a free plugin for simpler Modbus communication if that's all you want.

Q3

I have no idea. I am using two cheap $5 BoBs and they work fine. You need at least one.

Q4

I am sure that those Bobs are higher quality than mine. I am though not sure they are worth paying for. Of course, if I was running my CNC commercially H24 then I'd buy the better BoBs but as it is now, I can't imagine paying that much for a BoB.

Q5

I have no idea, but I suggest you register on the CNCdrive forum and ask support. They are very fast in answering and helping out. My guess is that you can connect it to any free inputs and after configuring the UC300ETH it would work.

Thanks for all the answers.

So "commercial" is a non cncdrive related screenset....

Ok.

Well need to start figuring out what i want to connect tot the motion controller then.

And if i can justify :-) purchasing ub1 based on that.

Grtz Bert.

I'm currently using a CSMIO-IP/M. The UC300ETH/UB1 combination is very similar with a few improvements from a hardware point of view, and I would be looking at the newer hardware if I were starting again now. As far as BOB functionality is concerned, things like differential motion signals, 24V signalling, isolated VFD analogue output, are all highly desirable. I like the idea of spring terminals as well - more reliable long-term than screw terminals. These are all relatively high-end BOB features and you don't find them in the bargain box on eBay. I have to say that my first router used a cheap BOB with 5V all round and didn't give any problems - but then, I wasn't using speed control or had any limit switches either!

1) I think that I'm the only one that offers a UCCNC screenset. It basically just adds probing, and auto zero macros.
As UCCNC is constantly adding new features, my screenset may not support all UCCNC features until I have a chance to update it.

3) The UB1 is not programmable. What you are referring to is the UC300ETH firmware. UCCNC actually loads different screens depending on the motion controller connected. As of about 10 version ago, UCCNC can detect the UB1, and load screens made for it.

4) 24V I/O, differential step/dir, analog inputs, charge pump output, speed control, relays.

5) Any available inputs, I believe.
