New start

Thanks!
Not using combined home/limits!
Went with mechanical switches for limits and they are no/nc.. so it might be ok :)

So true :)

I have been curious for some time now.. where in Sweden are you from?
And do you make money from your cnc endeavours or is it only hobby usage?
Have found alot of inspiration from your YouTube channel!

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

Congrats on getting her going, everyone cuts a circle lol.

My first circles were off by about 1mm I read a post by Jazz about rising/falling edge so I flicked the jumper (No. 8 on my AM882) and now the sizes are correct.

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.

Hmm have read about that a couple of times.
Have to try it and see if there is accumulation.
But for it to be real obvious I should write a program that takes the axis back and forwards ALOT of times to see if the position changes? :)

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?

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