Need help configuring a 5i25 with Gecko G540

Hi,

I just installed a Mesa 5i25 card, flashed it for the G540, and commenced configuring PNCConfig, I have got some way in that I can test drive the stepper motors OK, If I leave out any homing I can go to the axis program and also drive the steppers back and forth.

However I am stuck on configuring the limit/home switches, in stepconf I had them set on pin 10 minimum limit + home X, pin 11 for Y and 12 for Z, I am trying to emulate these settings without any luck on I/O 3. I think I have the search direction and velocities correct (maybe not) but when I run it I cannot turn power on because I get Joint 2 limit errors.

Also I have no idea how to get my router to be controlled via pin 14 at 0-5v and 50Hz as the G540 requires.

I'm not sure what info I should provide to assist so some hand holding and guidance would be appreciated

Eric

thanks for the quick reply, I have already tried that with and without inverting, swapping them around in different gpio inputs, and nothing seems to make a difference, hence my posts.
I can post whatever files may help, I am just not sure which would be helpful.

(in stepconf I have them all inverted)

Eric

Your hal & ini are a good start

Of course, here they are.
also I have been fiddling with settings and in stepconf I had all limit switches inversed, if I do that on pncconf I get all joints on limit error, no error if I uncheck the inv box, however I also get no feedback detected from the G540 when a limit is activated, there are other confusing issues which will have to wait.

Thanks for the support
Eric

BTW, the hal and ini files are difficult to me to follow.

I dont think pncconf has direct g540 support so the assigned 5I25 GPIO pins for the limit switches are wrong

If you use a G540, the inputs are mapped like this:

INPUT1 GPIO13
INPUT2 GPIO14
INPUT3 GPIO15
INPUT4 GPIO16

Thanks PCW,

I did read that matching, from using --readhmid etc,

but I still do not understand how to match them in the I/O 3 tab.

I have included a screenshot of my I/O 3 tab, perhaps I have not got things quite correct from the start. Should I see numbers like GPIO13?

I was suggesting theat pncconf doesn't seem to work with that combination so you would have to edit the hal file directly to connect the limit switches in hal

Thanks Peter,

I needed to change Min X + Home etc for each axis to Home X Home Y etc then hand edit the HAL file to change the GPIO numbers as you indicated.
This is now working in that I can turn the system on, home the axis as per the pncconfig file I created for each axis (when I remembered to switch from mm/s to mm/min) then move and touch off and run a job.

So a big thank you for that.

I would now like to control my spindle by setting the output on pin 14 to switch between 0-5v and 50Hz base PWM freq. (does the 0-5v depend on the PC's bus? mine is 3.3v) and also spindle on

Thanks again for your help.
