pncconf in master supports the 7C81

To use older pncconf with the 7C81 you can make
a configuration with similar hardware (stepgens PWMgens etc)
 and then change the driver name in the .hal file
and card name in the .ini file.


So for example to make a simple step/dir setup
you could choose a 5I25 and prob_rxf2
 then change the:

 loadrt hm2_pci xxxxx

 line in the hal file to:

loadrt hm2_rpspi xxxxx

and the

CARD0=hm2_5i25.0

line in the .ini file

to

CARD0=hm2_7c81.0

 

Alright Ill give editing it a try and if it works Ill try and post it, if not Ill try axis

Thanks mate

Axis GUI can be made to work in portrait mode nicely, and QtPlasmaC has a portrait mode in several sizes.
QtDragon will probably need some editing in QtDesigner to work in portrait mode as i do not recall seing it here.

Hello,
Thank you for your help. I have managed to enable SPI. 
sudo mesaflash --device 7c81 --addr /dev/spidev0.0 --spi --readhmid, now shows that the card is present.
I probably will update to another Pin-configuration for the Mesacard.
How can I use the hm2_rpspi driver? I wanted to build my machine config with the  PNCconf  Wizard and then modify the .hal and .ini files for more things which are outside the capabilities of the Wizard. 
Maybe someone can give me a push in the right direction?
I a have little experience with LinuxCNC and Linux in general.
Also I have used xrdp remote client to access the PC headless and it is giving me trouble. If I install it it works fine, but when I restart the setup the screen shows some distorted mess of pixels. Maybe someone has an idea what goes wrong there?
 

Hey guys are title says, wondering if anyone has had luck running QTdragon on a vertical monitor as when I try most of it is cut off the screen and full screening with F11 or trying to resize it makes it worse.

If this is not possible is there a LinuxCNC GUI that works well with this set up? 

Thanks guys  

Hello,
I have just started working with LCNC and I am therefore an absolute beginner. 
I have found the files for qtdragon lathe on github (share/qtvcp/screens/qtdragon_lathe).
Unfortunately, it is completely unclear to me where I have to copy these files and which adjustments are necessary so that I can start qtdragon_lathe. Maybe someone can name the necessary steps.
Best regards

i've been taking a look at this page wiki.linuxcnc.org/cgi-bin/wiki.pl?SpindleOrientation. what would i have to change to get this to work with my setup? Obviously, where it says "board" i would have to insert my board, but what other changes would i have to make to it to get to work with my 7i96s with servo spindle? i did notice i needed to change the port numbers in the file to match my board. is there anything specific i need to configure to make this work? Thank you for all your help btw.

WOW  4Kg is a lot of weight for a couple 2213 motors and 10" props to get into the air. That said you definitely
wouldn't be worried about the wind. You would probably need the wind to get off the ground. I will admit my
expertise in such matters is limited. If it were me I would probably go with a delta wing or a flying wing design so
it would cut through the air nicely and still give lots of lift for the weight. The old Avro Vulcan bomber would
give a good starting point. Lots of wing area . At that point though one would need to think about what size
servos and or how many to use per control surface.  For my stuff I am staying in the under 1Kg region.
For now anyway. LOL

There are stand alone modules made by people other than  Beckhoff.
one is the Rtelligent RTEC1616 which has 4 PWM outputs

I agree the waveform is weak.

After some deliberation I decided to replace the encoder and try one of these cheap hall effect chips (AS5040). I chose this one because its 10 bit resolution matches the max I read in the WJ200 manual. 

I 3d scanned the top of the servo drive to get the locations for things. (loving this Einstar scanner)
 

The scan wasnt perfect so I iterated the top diving board twice to dial it in. 
   



Then I soldered up some wires and fed them to the fanuc wiring already in place. 
 

Now I have a good 5v square waveform on A B and Z.
 

I will likely replace the 3d printed parts with metal parts once the machine is up and running. I wouldn't want to have problems because the servo gets warm down the road.


 

i think 5V is better, since the 3.3v regulator is already on the board anyway.

DId you mean 7I92+7I77 as I suggested?

I would make a 7i92+one 7I77 configuration with pncconf
Get the basics working and then add the additional I/O

Do not change the basic 7I92+7I77 hal/ini file set until
everything on the 7I77 works.

As I mentioned, checking the encoders on the 7I77 would
be a good first step to verify your cables

BTW those cables are much easier to make with
IDC (press on) connectors.

Also, as far as I can see from the picture, the HDR26 --> DB25
cables are not correct.

They appear to be

HDR26    DB25
1             1
2             2
3             3
4             4
...

But should be:

HDR26    DB25
1             1
2             14
3             2
4             15
5             3
6             16
7             4
8            17
9             5
10           18
11           6
12           19
13           7
14           20
15           8
16           21
17           9
18           22
19           10
20           23
21           11
22           24
23           12
24           25
25           13
26           NC

That may seem odd but that's the pinout you get with
IDC (Crimp-on) flat cable connectors. Its odd because
HDR26's and DB25's number their pins differently.

Thank you for helping me out
Do I need firmware for my boards in folder /firmware/hm2 (For 7i77, 7i74, 7i70, 7i71) ?
I tried Pncconf with 7i92  and 7i76 and then deleted all the lines with errors for 7i76 and linuxcnc started
