How to build a spaceship with Linuxcnc and a Mesa 7i76e

I've had in mind to do this for a long time. But here is a tutorial about how to start with a Mesa 7i76e


It covers all the basics:

Power connection,
Mesa IP address config
Connecting inputs - mechanical and proximity sensors
Connecting relays and triggering them with M3/M4 and M64/M65

There is still more to come.... but I thought 50 minutes was long enough.

But if you are just starting out, it will be the best 50 minutes you'll ever spend!

Very nice Rod - thankyou
Can you include a reference/URL to the (Norbert ?) connection diagram you mentioned?
Thanks

just google it or search on this forum for "my 7i76e connection sheet"

it's here

Fantastic introduction!

I have been foundering a bit as I have no experience with any of this electronics stuff and your video has provided some key fundamental insight. A question or two if I may... I think I understand that I can signal the turning on/off of 110V peripheral device such as a shop-vac using one of those electromagnetic power relays, correct? Question is, what size/type fly-back diode to be used? Are they sized for particular load (amps?).

Much appreciated.

An IN4007 is all you need. The IN400X series basically just have different voltage ratings so 1000V should be enough!

Thank you just what I needed.

I appreciate your time in creating this.

Cheers

Hi Rodw

I purchased the MPG pendant i think it might be the same as yours, although this has the screen.

I have been trying to find the post in the forum in which you discussed this so that i may add to it.

I purchased a 7i96s with a 7173 and a 7i95T. I will porobably go with the 7i95T as it has lots of I/O for future expansion on my CNC and some planned projects i would like to add to my CNC.

Im still new to CNC although i have been involved with 3D printing since its inception, which gives me some transferrable skills. Im an electrical engineer by trade so although a steep learning curve, im sure i will succeed in my venture.

The reason for my message is the pendant i bought i chose as it has the STWGP interface for connecting to my 7i95T.

Would you have a wiring diagram you used for your connections between your 7i76E and the STWGP.

Im just striking up a conversation with the manufacturer of the pendant and he has asked for a wiring diagram to check its suitablility.

I was hoping if you dont mind to use your connections as a base for my wiring scheme.

Anything further you can add or setup files would be greatly appreaciated, or if in the linuxcnc domain a link if you wouldnt mind.

Kindest regards
Andy

Did you have a look at this?

linuxcnc.org/docs/html/examples/mpg.html

This gave me the basic idea, and then I could change the *.hal according to the requirements.
To me it looks that this wireless thing just connects to the machine like a normal wired device.

I am not using an "official encoder input" for the MPG just normal inputs were doing the job, So I did not change the bitfile on Mesa card plug and go kit.
