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

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.

Thank you

I don't think there is a way to write from LInuxcnc to the MPG Screen. I think it must use the USB for that.
As far as the wiring goes, the circuit diagram on the receiver is all you need as each part is a seperate set of pins.
The estop is designed to be standards based with two redundant circuits but it works for a single sided estop as well.
You used to have to ask for a 5 volt encoder for mesa but now I think there is a switch to select between 5v and 24v on the board.
I always have used the digital I/O for axis and jog speed select to save pins (with a MUX8 or MUX4)

This recent config I did uses the same pendant and there is a seperate hal file and also a custom component to manage the three jogging buttons
