That looks all good.

Phil,

Just wondering what program you used to draw up that diagram, I am about to convert my machine to open source linux from CommandCNC and I need to draw up something very similar. You wouldnt happen to have the diagram in a DWG format you could share?

Here you go, the forum doesn't like DWG so just take .TXT off the end. If that is no good I can do DXF. I use QCAD-Pro.

Cheers, Phill.

Phil, Aside from adding limit switches it looks good! You got the inputs so put them in where you can. I use PNP prox sensors so all wiring is on the gantry. On the Z axis, I ran a 9 wire cable up with DB9 connectors. 2 wires for 24 volts and that left 7 inputs.

PCW has suggested you can use the onboard spindle relay to turn the torch on but I do it the way you do it.

To be compliant you are not meant to use relays on an estop circuit as it introduces a further point of failure. I used a cheap estop from Jaycar which has two sides to it. One sends a signal to the 7i76e and the other side trjps power to the stepper controller 48 v power supply.

Then I added a pendant and another estop button which are all chained together in hal using estop-latch.

If I did estop again I would use one of these switches becasue you can clip on additional switch mechanisims behind the button.

Finally a friend suggested to add a led indicator for each power supply in the system (Plus I have one on the gantry). I have found that very useful isolating faults. You wonder why its not working and then you check all the power is up before panicking!. I added another LED on the gantry breakout box power.

Hi Guys,

Instead of starting a new topic I thought I would add to this one,

Can I get some help proof reading my wiring diagram,

There might be some things that stand out that I should change, Just want to be sure before wiring up the beast!

@Stefan,

Your Pdf is rotated 90 degrees. My neck could not last that long.



Your mese thcad10.... You use a divided arc voltage in from cpc 5 and 6...
I thought for your resolution, mesa is designed for a raw arc voltage? If not why don't you use 0 to 10v input with different jumper settings in HP?

The Metal Box text can be also, " thc module "

I miss the future modbuss port and the future mobbuss connection to the mesa. This one is easy. The python code for the modbuss HP protocoll is provided by the pakastani/india friend at this forum about 2 years ago.

The Estop circuit is a problem. Are you in America?

For The fabricator i give a value of 8 out of 10 for this post. Very, very nice to see this development into the linuxcnc forum.
Nice done !! Very good illustrated. It does me to think about manhatten style. And if that is so, Mesa is learning from you.
