HAAS VF1 retrofit

OK, Mesa boards arrived today. So I can get to work this weekend.

I already mounted the motherboard in the same space as the old controller.
Taking pics as I go.

Tonight I will go back over to the shop and grab the input/output panel out of the enclosure
to mount the 7i77.


I have one question how did you guys get so familiar with programming?
Do you have coding experience? You make it sound so easy but it is still over
my head.

I have read a lot of the documentation but it reads like I need a little more to understand it.

What do I need to read/learn in addition to the LInuxcnc docs ?

Thanks

Well tonight is a bust, did not realize the HAAS I/O board was attached straight to the enclosure panel.
So I will be stopping by my friends sheet metal shop in the AM to have a stand off plate made.
The I will mount the new Mesa I/O to it.

The original board is pretty simple, has a bunch of optoisolated transistors on it and 12 volt coil relays.

I learned C from writing components for my machines. I had prior gcod/ macro experience and some plc programming with a langauge like basic. I had ALOT of help from Andy and Arceye(who I have annoyed a few times...).I hate ladder, so C was the only other option.

Keep in mind, no matter who you are, this takes time and you will be way ahead to work on something small on the bench.The first machine I did was a Hardinge HNC , and before I actually moved an axis, I had gotten motors tuned and working on a bench set up.I did the same with i/o using some opto boards and switches. The hardinge took me about 3 months of spare time to rewire,set up, tune and program.

there are different ways to approach the hal file and logic. Some folks do logic in their hal file, some do it in Classic ladder and some (like me) do it as components in C. I like my hal file to only be connections and each individual machine function to be a component. I dont know if the developers intended it to be done this way, but it works.


Most importantly make sure your machine is safe.....

Well I screwed up...

Bought a motherboard with out a standard PCI slot.

I am not going to return the 5i25 to get the 6i25.

So I am searching for another motherboard instead and I will just transfer
the processor/memory etc... i figure this is the least expensive fix.

Edit...just ordered a GA-H61M-S2PV

Yea I am going to try to return it and see if they take it back, i bought it from the tiger direct store here in town.
I ordered the new one online through them also. It wasn't available at the store for pickup.

But if im stuck with it, ill put together another PC for the house.


Owell if this ends up being the only mistake i'll be lucky



I looked up that adapter...yikes $$$

May I ask why?

I ask because I am at a similar cross road. I have an ATX MB I can use, but would much rather use a mini ITX MB, so I was looking at ordering something.
If one HAS to order something, I would think one would want it to be as small as practical and use as little power as easily practical, so I am curious.

Thanks.

Well originally the local TigerDirect only has micro ATX as the smallest motherboard in store.
We have Tiger Direct stores here in Florida.
And I already drilled and tapped the plate to mount it. So I'm kinda stuck with what I have.
Also I don't want to have to buy another CPU and memory.
Also someone on here already tested the new board and it seems to have excellent latency.

Now I have a friend with a sheetmetal shop that has a press brake with a bad controller...
So I have him watching my progress now.
