UC300ETH: UCBB Vs UB1 breakout board ?

[routercnc]

Thank you Dean, that was very helpful.

Careful hear because you need to factor in UK VAT and postage. You will get charged VAT and a fee from the shipping agent which I believe CncDrive uses FedEx now as the shipping agent they used before no longer delivers to Uk since we left the EU.

Ah yes, good to know !

However, If you don't need loads of I/O then I'd give the AXBB-E a good look over because they are a fantastic neat little package, I fit these to nearly every machine I build these days except machines with ATC, etc that require lots of I/O.
In performance terms, it's exactly the same motion controller as the UC300, just with fewer ports. It also has a 0-10V analog output, unlike the UCBB.

I did look at the AXBB briefly but didn't go into the detail. Looks interesting. I need 5 axis control (2X, 1Y, 2Z) and this offers 4 by default. It says another 2 can use configurable I/O pins to make 6 in total. I'm trying to work out if I lose too much by doing this and am going through the manual.

Aside from the steppers the other inputs/outputs on my CNC machine are:

2off prox for homing X axis both sides
1off prox for homing Y axis
1off prox for homing Z axis

1off limit prox on X axis
1off limit prox on Y axis
(no limits on Z)

2 estop switches

Probe input

Pendant controller, but I don't really use it so not a big deal if it can't be used

In/out not required:
I have a direct manual start/stop switch and pot for the VFD control mounted on the main cabinet panel, direct to the VFD. I don't really go for software/BoB control for these but that is my personal choice and so is not really needed on the BoB.

Also no plan for ATC any time soon so that is not required for I/O


AXBB-E also appears to have an additional connector for something like the UCSB to give more in/out, but I would like to see if the above requirements can be met without it.

Also, If you don't want to buy direct from Cncdrive then I have both in stock and can provide the license file for UCCNC.

OK, good to know. I need to check the above, then will email for all in price. Thanks
