You missed an excellent opportunity recently, a LinuxCNC meetup in Stuttgart.

I was going to say thank you but you just made me cry

Just a question. Is it allowed to post a request of that sort here on the forum?

I thought you just did?
But you could do another in "User Exchange"

We used to have a user-map, you could see who was close.

I will make one there too than, never know.

How far do you live? Any "free" holidays to Bruges planned in the near future?

If they had sent me rather than a colleague I would have been working in Lommel all last week.

(I am in the UK)

I would have gladly invited you to spend some days in Bruges@Hostel Lybeer.

Well the UK isn't far... So maybe if you are interested? I know that it is asking a lot... But it can't hurt asking it I believe. I am more than willing to come there aswell. In my stage I don't need to bring a machine... I can just bring one driver and a motor in my bag

I'm just an unemployed road laborer without a 6i25 card to play with. Just a matter of reading the manual and taking a single step at a time. But then again it's so easy to misinterpret something, we've all done it.

I figure if a boofhead like me can understand it anyone can :laugh:

I wouldn't start doubting yourself, it seems like you've been going at it a while, best thing to do is to walk away from it and occupy your mind with another task and come back to it fresh. Usually it'll take 2 seconds you'll see the problem and slap yourself on the head.

Hi all,

Special thanks to ozzyrob and andypugh for a start!

Just got back from holiday. Switched the jumpers... Looked at it with fresh eyes as Ozzy suggested. Managed to find out I was working on the wrong port and I was counting the pins from the wrong direction. So my wires on the 7i85s where not on the correct pins.

I managed to get the driver and motor basically to work. Now comes the rest. More difficult questions will follow soon

But once again, thx all for your help so far. I got it running, that's a hugh part for me in starting to understand.

So my first three question are..

1. Can I get a stepgen type5 working on the 7i85s? Here come my previous driver into play uln2003... 6motors need to be connected. 4 wires each.

2. Can I get microservo motors running on 7i85s? Only 3 wires come out of these motors. +Vcc, ground and signal. (6motors)

If not what Mesa boards would I be looking for, so I can order them.

3. I have 8 step dirs on this 7i85s. And 8 encoders which is great but I would like to have free gpio pins to connect all limit switches seperatly. Is this possible on these cards, can I free up the gpio from the step dir and encoders if not used or are they preset anyhow.

Thanks

On question #3, that is where I used a 7i84. I will connect to one of the 7I85s boards via sserial (smart serial). you can interconnect tehm with a cat-6 cable with an rj45 connector on one end.
Lots of GPIO pins available!
