You can use a THCAD2 or  THCAD-10 with a series resistor
or resistors, for example  2.4M will give a 250V full scale range.

Mesa has a set of three .4W  1M .1% resistors for this purpose, when used
with a THCAD-10  or a THCAD2 set for 10V you get:

1 = 110V full scale
2 in series  210V full scale
3 in series  310V full scale

Note that lower voltage ranges improve resolution so the 210 V range is fine for most
plasma systems as it will accept continuous inputs over 1000V without damage
and voltages over 200V are not typically useful when cutting.

Kein divider, und kein ARC_OK, aber
noch 2 mal die 1MOhm/2W resistors und ein "reed switch/reed relay" ist alles notig, etwa 5 Euro total

That should pretty much cover everything... i hope!

Does the sim work? If so its a configuration problem.

Hello guys! I've just noticed that I/O map for 7i95T from Mesa Configuration tool 2.1.7 is not complete.
The I/O map is missing connector TB5 and TB6 or am i just looking at it wrong?

Or is it because I'll have to configure inputs & outputs under the 7i95t tab to get pin names in my I/O.hal?

 

Thanks! I solved the problem :d I added an additional external brake resistor .

I think the topic is for deletion.

 

ich wollte eben meinen text über korrektur reinschreiben bekomm ich immer kuna debug error 
Hallo @tommylight,

Entschuldige, du hast vollkommen recht, das war mein Fehler – ich habe den Ausgang vor lauter Pins nicht mehr gesehen. Es ist schade, dass es bei Mesa keine direkte Übersicht darüber gibt, was die Karten können, sondern nur den Text; da kann schnell etwas übersehen werden, was dazu führte, dass ich die 83 mit der 77 verwechselt habe.

Wir haben auch schon an die 95T gedacht, aber leider war sie bisher nirgends verfügbar. Der Grund, warum wir sie jedoch nicht in Betracht gezogen haben, ist, dass das System dann weniger modular und austauschbar wäre.

Es war gestern eine lange Nacht des Lesens. Bevor wir deinen Text gelesen haben, hatten wir noch folgende Idee:

7i92TH (Hostplatine)

7i76U (Step Dir E/A und die Potis über TB6) IDC26F > DB25M

7i85 (für die Encoder) IDC26F > DB25M

7i83 (für die Servos) über Smart Serial

Alles modular und bereits vorhanden. Diese Teile wären sofort verfügbar. Das Gute ist, dass die Maschine ja noch nicht gebaut ist, nur die Servos liegen bereits hier.

Falls wir die Maschine mit mechanischer Spindelsynchronisierung bauen, würde die Encoderkarte wegfallen, und wir könnten das System entsprechend anpassen.

Bezüglich der Firmware wäre ich in der Verbindung unschlüssig:
7i92t_7i76_7i85d.bin
oder
7i92t_7i76_7i85sd.bin

Danke für deine Tipps! ?

Apropos, kann man dich auch per Remote für eine Konfiguration anwerben?

i stuck at his point i think its not possible ..

In the Axis software:
this line latches the power relay to power up the esab machine (F1)
net estop-out => hm2_5i25.0.7i77.0.0.output-03

and this line enables the Axis interface (F2)
net machine-is-enabled => hm2_5i25.0.7i77.0.0.output-02

Hi guys. My migrated qtplasmac config (from plasmac) is not working as expected. The conversion ends with auccess but when I launch qtp both estop and power buttons are inactive, i.e clicking them does not do anything. The same buttons work fine in Axis. My setup uses the estop button (F1 keyboard button) in Axis to latch a relay and power on the plasma table central power unit and the F2 keyboard button to enable the Axis interface.  Both axis and qtp contain the same lines for estop-out and machine enable. I set estop mode to 2 (button) but I still get no sign of life when pressing the estop button. I have a physical estop button which is not connected to linuxcnc. It does cut off the plasma machine when activated. I will post the ini file for review. 

I tried replacing the image links with uploaded files directly but i does not work.

Even files way smaller then 1.6Mb ( 1.1MB) the forum complains its to big. So I'm open for suggestions.

For the Rails: They are from the THK NRS Series. Size 35mm and 44mm overall height (Non standard)

Also the bolt pattern is a little bit odd. See Datasheet attached. If, by any change, you have this exact model, I'm definitely open for negotiations

 

Hi,

i'm looking for a good plasmacutter that works with plasmac.

What if the plasmacutter doesn't have an internal voltage divider ? Then the THCAD 300 would be good, but its out of stock everywhere. What is the alternative if I want to use THAD 5 oder 10 ? 

To buy a Proma voltage-divider or is there another professional-looking alternative ?
And maybe you can recommend a plasmacutter for plasmaC ?

Thanks.

 

I recently had a marvel v10a automatic band saw fall into my lap. It's in pretty rough shape and I am considering doing a restoration on it. I was told the electronics are in potentially broken condition. I think it would be a neat project to retrofit the control, and would be useful to be able to upload cut lists to the machine via USB to further automate the cutting process and have a hmi. The machine does not currently auto miter and only allows 1 direction mitering. I think I can modify it to miter both directions, but need to further investigate if i can I will try to add auto miter. This thread will serve as a build log if I make progress on the project. Has anyone seen any examples of retrofits being done on band saws? What would be the best way to go about taking on this project. 

You should not need to install any drivers.
Does

Show your card?
 

Hello all! I am very new to LinuxCNC and have question about how to install a kernel patch.

I have a PCIe parallel port card with a netmos 9900. The driver that came with does not work, and I found this patch on the kernel site:
git.kernel.org/pub/scm/linux/kernel/git/...6917eeda4284ed220079  

In usr/src it shows my current version is 6.1.0-30, which I assume is the latest since I just downloaded it. The patch seems to be 6.08 (?)

My question is, can anyone guide me on how to install this patch? I found some information on patches that had "patch.gz" in the file extension, whereas this one seems to be "tar.gz" and those tutorials don't work. 

Otherwise, does anyone know of some kind of guide or video on how to install this particular kind of patch? I apologize for this being such a general question, but I am very new and don't really know how linux kernel works! 

Thank you in advance.
