Hello, I am trying to convert my lathe to LinuxCNC. I am using a Mesa 7I96 and want to connect two MPGs—one for the X-axis and one for the Z-axis—using the standard inputs. Does anyone happen to have an example configuration they would be willing to share?
Many thanks,
Hans

Many thanks.

Bei der Anleitung für pncconf gibt es eine Seite External Controls. Ich komme beim Einrichten von LCNC über pncconf
nicht auf diese Seite. Ich habe übers Terminal die 7i96_inmd.bit auf die Mesakarte geladen. Überschreibt dann pncconf
diese Firmware mit der internen von pcnconf?
 

Im PncConf:

Hello,
when I start LCNC, the axisscreen is minimized and i can it manually maximize. In what kind of way its possible
to start Lcnc in Fullscreenmodus?
Thanks
Hans
 

Here are some older PC's that have been tested for use with LinuxCNC:
forum.linuxcnc.org/18-computer/38838-har...ts-used-pc-s?start=0

I dont think pncconf fully supports MPGs

To add a MPG encoder to TB3 on a 7I96, you would need to

1. use 7I96 firmware that supports MPG encoders on TB3,
like 7i96_inmd.bit
 
2. Connect the MPG encoder count pin  to motions jog
axis and or joint jog pins, something like:
(for 1 MPG controlling all joints.axis)

net jog-counts  hm2_7i96.0.inm.00.enc0-count 
net jog-counts joint.0.jog-counts axis.x.jog-counts
net jog-counts joint.1.jog-counts axis.y.jog-counts
net jog-counts joint.2.jog-counts axis.z.jog-counts

3. Other MPG setup
 The main MPG code can be taken from other MPG examples plus
pncconf may be able to set some of this up but does not support the
inm MPG encoder inputs, so that would require the above connections
at a minimum

Some modern ones do.
There are PCI or PCIe to LPT cards too.
But this does not mean that a given computer is suitable for LinuxCNC because it has LPT port or LPT card.
There are other factors that determine this.

playing around

Vielen Dank PCW für deine Antwort. In dem Menu für P3 kann man keine Kanäle für Handräder auswählen, ich komme auch nicht auf die Seite
mit External Controls und kann auch nicht auswählen: Ein Handrad für alle Achsen oder wie bei mir ein Handrad pro Achse? Kann mir da 
jemand helfen?

You can ignore that message, it does not apply to the 7I96 or any current card.
Then when you get to the "Mesa Card 0" page select "7i96-Internal Data" for board name
and "7i96d" for firmware and then press "Accept component Changes"

 

Hi 

I saw a video here : www.youtube.com/shorts/e60EBb8NXKA
It seems to have a 4 axis machine doing undercuts and true statue carving.
I have extended my LCNC 2.9 version recently with a rotary axis, so now I have X Y Z and A axis. Rotary is parallel to Y.

I am looking for some CAm software like the one used in the video to carve extended arms and horns as done in this video.

Which CAM am I looking at ? The comment in the short video says  powermill, alphacam, UG.

I tried desproto 7.1 and was able to create their venus model perfectly. But when I put a more complex design with statue having extended arms, the CAM seemd to not be able to do it or there was complex setup for the same.

Can someone suggest which CAM has builtin PP and support for linuxcnc for such carvings ?

Cheers
Ritu
 

Hallo,
ich versuche jetzt die 7I96 mit Pncconf einzurichten. Ich bekomme sinngemäß die Meldung:
Ältere Karten brauchen eine Firmware, keine Firmware gefunden. Pncconf benutzt die
interne Firmware.
Wo bekomme ich die richtige Firmware her? Mit den Steuerungspc komme ich jetzt nicht mehr
ins www, weil die Karte ja am Netzwerkanschluß hängt?
Im voraus vielen Dank
Hans

Do "old PCs" still have Parallel ports? .

Yeah, I've seen that, but I'm very reluctant to start nuts and bolts messing with a system that works for me. Had a good look at Flex, but the installation etc. is still pretty opaque to me - add to that the fact that my LinuxCNC PC is sat offline everything becomes that bit more complicated..!
