Doh....That was it!

Thanks!

Make sure 7I96 W8 is in the down position.

If not, standard parallel port BOBs will short out the 7I96 5V supply

(W8 should only be in the up position for Mesa daughtercards that
get 5V power from the 7I96)
 

Hey Everyone, 

I flashed a mesa 7i96 (non s) with the 7i96_5abob_d.bin firmware, and tried to connect the bob but it would cause the 7i96 to power off every time.

With the ethernet port facing the left. Red line on the cable (pin 1) is pointed up (closer to the ethernet port). If i flip it around it doesnt short but it also does nothing. (flipped every gpio pin above 34 pins output and wasnt able to cycle the onboard relay) also steppers didnt move.

Tried with a second 7i96 with the same result. 

I've tried powering with the usb, powering via terminals, removing the jumper on BOB, adding the jumper. Nothing works.

Funny enough i have a 7i96s with a bob that works perfect. Tried to connect the 7i96 to that bob with its cable and it still shorts. So its not the wiring or the bob, its prob the firmware on the 7i96.

I've power cycled and used readhmid to verify it got the flash. The only odd thing is it has 3 steppers not 4. I also tried the 7i96_g540 flash to see if that would help but same issue.


Any help would be great.

Here is the board. Tried another green one that looks just like it with the same issue.

Not sure about the other errors but P should be 1000
(for all joints at a 1 ms servo thread rate) A P value
of 0 will work for a while but the joint will drift because
there is no position feedback.

The hal file is incomplete, if you cannot get out of estop, this is likely an issue
with the EStop related signals and these tend to be at the end of pncconf created
hal files.

Did you setup an external EStop? That might be another reason for inability
to get out of the EStop state.

Hi...need help..on 5 axis setup...A Axis now is not coordinated..also gives false warnings about going beyond a limits in file at line 72...
I have used this machine before in a similar way but not rotating more that 90 degrees either way...seems like it keeps looking to end of file and then starts moving continuous ahead of other axis??

Thanks for any help!!

Rick

You are welcomed, always.

Parport base address set to 0x2000 is the solution. Now the motor is working! Thank you very much!

I have a something similar setup and you should be able to do it with the one configuration. Since linuxcnc supports multiple spindles I just made another spindle instance and then used a mux2 component to switch between outputting the axis velocity and spindle velocity to the mesa stepgen.  I think I just used the spindle.1.on signal to switch the mux2 component.  That way when I issue m3 s100 $1 it will run the second spindle at 100 rpm.  There could be some issues keeping position if you switch back and forth between the modes depending on how things are setup.    

In StepConf wizard, the "parallel port" page there is an entry for "parport base address" so set that to 0x2000 and test if the stepper moves.
If not, also try 0x2010 but it would be good to reboot the PC before testing it.

Habe ich das mit der Konfig der mesa Karten richtig verstanden, dass ich zuerst herausfinden muss wieviele Ein- und Ausgänge ich brauche um dann die passende Konfig auf die Karte zu spielen?

Installiere linuxcnc auf den Raspberry und starte einfach pncconf, dann kannst du dir die Mesakarte aussuchen und siehst selber was man braucht.
Du brauchst die Steigung deiner Spindeln (der Hersteller gibt 0.00375mm/schritt an, also vermutlich 1.5 oder 3 mm).
In pncconf werden Takt/Richtung für die Achsen fix vergeben sein, du musst den Pins nur korrekte Achsen zuordnen. Dann noch angeben an welchen Pins welche Endschalter hängen und das war eigentlich schon alles. Also praktisch nur von deiner HAL-Datei abschreiben.
Oder du schaust hier:  linuxcnc.org/docs/html/config/pncconf.html

If the "Emergency Stop" button (red X) does nothing, this is likely an issue in the hal or ini files.

Can you post your hal/ini files here?

Axis should look something like this initially (before estop is released):


 


After Estop is released and before power (Orange button) is on:


 


and after power is on:


 


 

On the stepper driver, the led is green and on the BOB there are 3 red led lights. I have a 36V 11A Stepperonline and a 24V 6A MeanWell power supply. I measured the output of the power supplies and they are working properly. For now, I just connected the X axis to test if the wiring is correctly and to learn to operate LinuxCNC.I also tried with another driver and stepper motor but is the same. Maybe because I didn't connected the Y and Z axis the stepper motor is not moving? Thank you for your time!
