Small and tired update.

When I took this picture it made me question what the hell I am doing ;)

All wood parts will be replaced and used as templates...

It will!!!
Why you are not satisfied with the UC300 usb version?
Here at post#158 Jazzcnc explains why the usb version is better than the parallel one.

The usb version is more vulnerable to signal loss and interference than the Ethernet version.
Both are better than paralellport.

But I'm sure the usb version will work fine for my needs.. as I'm only running 40cm of shielded cable mounted to the motherboard it should work flawless :D

Now I have to research what other BOBs or relays I want/need for running extra equipment such as lights and dustvac and such :)

UC have a USB or ethernet solution, Jazz was comparing using a PC with PP for step generation. UC cards are step generators. It gets confusing because like me nr1madman is using a cheap PP BOB to connect to the steppers, switches etc.

but the connection to the PP BOB is running a lot faster than if it was a PC PP. A few people have warned that using that cheap board will limit upper performance but I was told you will be able to run at least 50khz per axis with that cheap board connected to a step generator if you need more you need a better breakout board. For my Mesa card it's £100 for the better BOB so I'm happy to use my existing BOB for now and 50khz is actually a lot depending how you set microstepping.

Between the PC Motherboard and the PP BOB (The red thing) what is that?

Lovely work ;)

Thats an uc300 motion controller. Sad to say it's the usb version. Got it real cheap from a forum user that didn't need it ;)

Sad and unsatisfied update!

Had 20mins over today so I ran to the shed.
Realized I read the connections wrong for the relays. Reconnected and got the master relay to latch with start button. And disconnect with e stop!

Problem 1. Something is wrong, when I e stop I kill power to 5v psu . This makes my uc300 disconnect from pc and a restart is required for uccnc to connect with uc300 again.
Will look over the wires and reconnect with 5v outside of that loop.

Problem 2. Red fault light is on at all 4 drives.
Guessing it has to do with the enable signal.. since its not over or under voltage (get 50.6v ac at drives they take up to 80v ac or 110v dc) and no holdingtorque so no over/under current. Have tried enable through bob aswell as running ena- straight to gnd.
This could have something to do with my bob aswell? The bob has a green led shining by the 12-24v sign. But a red led right by the 5v pwm text.. is this normal or is it a error?

And another question!
How do I know the port nr to use in uccnc?
Easiest to connect switch and watch in ports and pins whats flashing? :)
