Help with adding PlasmaC to base config + 7i76e

Do you have torch enabled on the lower left on the main screen ?
Your files are OK, and spinena is properly connected to torch on.
When you press F9, does the Z axis move downwards ?

I didn't think to home the machine first before trying F9, now it travels down after homing.

As far as the float switch it may be a wiring issue, I'll check there first.
Thank you!

Still haven't figured out the float switch issue.

My old setup used a 5v power wire going to my float switch. When the switch is pressed it sent signal to the input terminal.

Now I'm using the same setup on the mesa board, with my wire landed on input-07 which I believe is pin#8 on TB6. However I am unable to get the GUI to acknowledge the switch when the switch is depressed and 5v is going to TB6 pin#8.

I use

A 5V signal would not be recognised by a 7I76E input, you need a minimum of 60% of the field voltage (14.4V at 24V field voltage)

Normally you would wire:
+24V field voltage --> switch1 --> switch2 --> 7I76E field input

Okay that explains that, thank you.



In case this thread is of use to someone else in the future, here are some links to the documentation and files I cobbled together to turn an old desktop into a working machine with mesa 7i76e & thcad10.
