    New AXBB controller

    CNC Drive is offering a free UCCNC license with purchase of a new AXBB controller (first 250 customers).

    forum.cncdrive.com • View topic - New ethernet motion controller+breakout board combo release

    I just ordered one to use for testing at my desk. And maybe for a laser build in the (near?) future.

    I have ordered one today. Thought about ordering another UC400ETH and a BOB for the new machine I'm working on but this looks more compact and the free goodie convinced me quickly.

    Re: New AXBB controller

    I understand the arguments for ethernet connections over USB for signal fidelity, speed and the rest. But ethernet presents some inconvenience as well. I'm curious: would it work to use a USB-to ethernet adapter, and run the AXBB (or other ethernet motion controllers like UC300eth) this way? I'm imagining using a laptop that lacks an RJ45 jack but has USB.

    Prudence aside, would this work?

    Yes, it should, but I'd make sure it's USB 3.0, like this. https://www.amazon.com/AmazonBasics-...gateway&sr=8-3
    It has to be fast enough.

    Also note that CNC Drives ethernet controllers have more powerful processors, and support some functions that the USB controllers do not.

    Re: New AXBB controller

    I use a tablet daily with UC300ETH or UC400ETH. I have a USB2 to Ethernet adapter to connect them and I never had network errors. (I have a USB3 adapter too, but the UCxx controllers work only 100Mbps, so the USB2 is enough.)

    Running it from USB only makes sense if you running a tablet or a small laptop which misses the ethernet connector. I'm running the UC400ETH from a desktop which has a ethernet connector, but good to know that USB2.0 adapters also work.

    This is what I had in mind when I asked. Many computers these days are showing up w/o the RJ45 jack.

    I think that the RJ45 will be still with us for a long time on desktop computers.

    Desktops yes, but for laptops, they are using Thunderbolt ports with break-out/expansion boxes for RJ45 connections.

    USB-C is the same as Thunderport?!
    I'm usually working with desktops only and the laptop I have is old but this Thunderport is interesting. I did not hear about it so far. Thanks for the heads up.

    Re: New AXBB controller

    Newer hardware has the USB-C "style" connectors. Best part about this is the cable is un-keyed and it can do bi-directional power transfers. Rather than say anything else here are a couple of articles:

    https://www.cnet.com/how-to/usb-type...nect-them-all/

    https://thunderbolttechnology.net/bl...-thunderbolt-3

    I'm all in favour on one cable style between any two devices, but no cables at all and with zero RFI would be even better :-)

    Thanks for the links and I like the all wireless and RFI-less idea.

    DHL just delivered my AXBB-E, can't wait to try it out.

    Re: New AXBB controller

    Looks like mine will be delivered today or tomorrow. I bought it because it checks a lot of boxes on my list, but I'm surprised how scant the information exists about this, at least on the cncdrive web pages I have read. Does anyone know if the processing power (max motor pulse frequency, etc.) is equal to the other products, like the UC300eth, or not? What is closest to in terms of total capability? I'm also struck by how the UCCNC software (I am playing with the demo mode version) doesn't even *have* the AXBB controller as one of the models to choose.

    I'm sure it means nothing, but it's curious.

    The answer is in the product manual (400kHz), right on page 1.: http://cncdrive.com/downloads/AXBB_E_manual.pdf
    Quote from the manual:

    The controller can output a maximum of 400kHz stepping frequency and can work withupto 6-axes, however only 8 dedicated step and direction signal pins for 4 axes are wired outon the board, but the I/Os on the software side are freely configurable to any pins making itpossible to use all 6 axes if required.

    Re: New AXBB controller

    Yes, if you run the latest development version of UCCNC, in AXBB demo mode, you'll see all the available options. It should be comparable to the UC300ETH, but with less I/O.

    I got mine yesterday, but haven't opened the package yet.

    I have got mine connected to the UCCNC today. Did not run any motors yet but the controller got connected and is running with the latest dev. release.

    Re: New AXBB controller

    Thanks for the help guys, this thing is cool (got it yesterday).

    I'm new to DIY CNC boards and home wiring. What sort of power supply(ies) would you run? The AXBB asks for 24V & 5V. Is that automatically (2) different power supplies? Meaning, do you ever come across singular ones that supply both?

    Also, suppose you were to run this with external stepper drivers. Does that automatically demand a 3rd power supply for the drivers? Suppose you were to run this with DMM or Clearpath servos... does that *also* automatically demand a 3rd power supply?

    Just trying to get my head straight about this. Thank you.

    Re: New AXBB controller

    Separate 5V and 24V supplies are best, as the grounds needs to be isolated from each other.
    I asked here:
    forum.cncdrive.com • View topic - AXBB power supply question

    Stepper motors need their own power supply, that connects to the drives. Depending on the drives, it's usually 48V-60V, but can be 24V-36V for smaller motors.

    DMM DYN4 drives are AC drives, and do not need a power supply.
    Clearpath and DMM DYN2 are DC drives, and do need a power supply.
