I have a Mesa 7i96 card, my ground is set to pin 10 I think, pin 8 is the touch probe, pin 9 is the tool height sensor. I don't think I can set each differently, so I have to have either port 8 or 9 trigger the probe. 

When I tried to put an or in my HAL, it gave me a pin not defined error.

What is the best way to implement this? I know the probe and touch plate work because the leds on the Mesa card show when they are triggered.

Thanks

Hello together.

i am Martin form Germany. I have bought a Knuth Mark Super CNC with a fault Controller (GPlus450) and I will not try to fix this old Controller.
The machine has servos with feedback and Maxsine EP100 AC Servo Driver so I think it is not a big deal to change the Controller to LinuxCNC.
I also have the electrical drawings of the machine.


I would use TCP/IP for connection so I think the Mesa 7i76e is fine for me, but this card is not available. So one alternative is the 7i96.
But this card has less in and output and I think I need a lot...

Spindel: CW + CCW + Analog
every Axis 3 switches (end, end, rev)
Lub level
Start/Stop
Drive X, Y, Z on
Cooling Pump
and much more....

So what do you think of this project.
How to start and what hardware I have to use?

Have a nice day
Martin

Adding some additional relevant logging info:

Hi Bkt,

Attached file compiles ok.
It sets the component name, adds a dot, adds the pin name. This total string is valid for sending.
Did not test it. But should work. -- more info click here --

Good luck BKT.

 

Hi Arciera,

Yes once you pressed the run button it optimizes in the background.
Once you see terminal output: file created, you are ready to load the result file "validation_xx.ngc".
If you have the validation file loaded and press run again, it optimzes the validation file.
In theory this should not fail. But i have seen it can fail. So why it should fail i don't know yet.
Have to figur out this.

The pointer is not valid, is a message that the memory is released for the entire operation. This is good.

Looks cool.
Yeah. looks cool. You can write down any bug's related to the algo. For example lines over lines. Are there exceptions to make?
Testing is welcome.

So are you thinking of moving on to the planner now or are you still thinking about representing the clothoid fillets in a more concise form rather than a bunch of G1 line segments? 
Before moving to the planner, testing the scurve algo is now in progress for 2 day's. I had some problems today. So it can take a while.

When we have ready :
1. Filletizer
2. Scurve

Then we move to the trajectory planner itself. In this planner clothoid's are represented by only 2 points and 4 double values.
So the clothoid linestrips as you see now, are just for representation, validation. In the planner you won't see them anymore.

 

That sounds like either the SPINX1A is damaged or perhaps the wiring is incorrect.

I would verify SPINX1 operation by running SPV+ and SPV- from 5V and GND from the
7I95 to verify its operation independent of the VFD

Also SPINX1A PWM frequency should be 20 KHz (though this should just affect ripple)

Yes its SPINX1A, the 10.75 voltage comes from the VFD, I have a delta VFD,and I have wired this way:
+10v -> spinx SP+
ACM -> spinx SP-
AVI -> spinx SPV

Between SP+ and SP-, I measure 10.75

If I reduce the RPM at 100 rpm, the pwmgen value is correct, but the voltage between SPV and SP- is still 5.45

 Hallo thanks for the suggestions, it didn't help, I'll approach the matter the other way round, from the servo side. I'll stay here in the post and not open a new one.the sevo is connected and has a connection to the Raspberry, the display shows 28rd, when I start Linuxcnc the emergency stop is activated and cannot be changed? the display then shows 48rd. I read the memory on the console with siitool and it worked without any problems. the 3 files are in the zip. can someone help me?
thanks Markus



 


 

Ich erstelle die Zeichnung mit Freecad und erportiere die als svg das übernehme ich mit Sheetcam bei kleinen Zeichnungen kommt man mit Demo aus ansonsten Voll-Version etwa ab 129,00 €

Is this with a SPINX1A?

The SPINX1A should have better than 1% linearity

Does the 10,75V vary?

Das ist die selbe wie ein Laser, mit PWM und ales drin und dran, hat noch die laser aus fuhr program stop and resume...

Mesa config does not have home/limit switches set up, just some stuff copied and edited from the prallel port config, so that will not work.
Use the PncConf wizard to make a new config, add home/limit switches there, it will set stuff up properly in most cases, even for a single input multi switch homing.

What RPM?
There is a project here using ESP32 in wireless mode for spindle encoder counting that works very well as described by the maker,
github.com/futurelink/linuxcnc-spindle-encoder
If you do have a high RPM spindle, do not bother with it as Arduino will not be able to count, for a 24000RPM with 2000PPR encoder you will have to count 3200000 counts per second or 3.2MHz !
Using interrupts in arduino might just get to count up to 1MHz, but that would be really pushing it.

pwm frequency is set to 5000
I've set the scale to 3225, it doesn't seem to make any difference.
I was not using PID for spindle speed, I was using lincurve.
However, I think that as long as PWM value is correct, the problem is somehwere else. I think the PWM value should go between 0 and 1, at max speed its 0.999, at 1500 rpm is almost 0.5, which seems correct to me.

I don't know what else to check :/
