Thanks :D
But I got even more trouble when powering the board via usb. Then it disconnected whenever I e-stopped ;)

Maybe the amperes are not enough from the PSU 5v for powering both the UC300 and Bob that is why you solve the problems when you get your 5vokts from two different power supply ...just a thought.

I think you might be correct Nick!
Either that or my thin long wires from the first psu are the culprit.. or interference.. ;)
The psu is speced at 5v 2A so it should be plenty?

Alright :D

First test cut made!



Was a bit of difficulties at first.
Got spindlecontrol working at first but with mayor problems.
Estop was tripping and uc300 was loosing connection from computer.

Disconnected speedcontrol from bob and ran only the start relay. Worked better!
Then when I started jogging the machine with spindle on I got false e stop again :(
Disconnected e stop from bob and only had it to control master relay.
Got the problem that when jogging two axis simultaneous uc300 disconnected.
I think the problem is my 5v psu so I hijacked 5v from my pc psu and ran to uc300 so that got powered from pc and the bob/driversignals from separate 5v psu.

This made it work :D :D

I have not reconnected spindle speedcontrol but Im guessing that works now too..!
Homes are working but my slaved axis (x/a) needs a bit calibrating. When cutting a grid of 300x300mm I get about 1mm differens in the diagonals. But there is plenty of adjustment available in the home sensor brackets so it's no biggie :D

2amperes is good but how thin are the wires?

It's 0.5mm2 wires. So they should be more than fine. They just feel thin/flimsy.
I'm used to 1.5mm2 wires ;)

Okey.. Had another false e-stop today while surfacing a spoilboard :(
But that is something I can chase, try, tinker with and scream at.

Have another problem, when homing my dual motor axis something have happened.
Uccnc seemed to release the slave axis (has to to square the gantry) when I paired them again I can't home?
And if I restart the computer I can home again but just once?
I can still home z and y how many times I want..

Suggestions? :)

What do you mean when say "When I paired them again" .? The software should be taking care of the homing seamlessly in the background and you shouldn't have to be doing anything.!

Well.. I messed up a "home x" session with an e -stop :D
After that uccnc said slave a axis to x axis but only x motor moved.
So I chose slave none, saved, then slaved a axis again.
Now they work while running programs and jogging but "home x" does not work as it should..

My bad but how do I fix it? ;)
