I make a drawing in few hours.
Its 5v i measured but later with the drawing it would be better to understand

I've replaced the standard kinematic file with your modified version, added extra joints and changed the config to inches to test in the simulation but I cannot reproduce your jogging issue in TWP mode.
I'm afraid I'm a bit at a loss as to how to troubleshoot this further.

Cheers Andy,

I'll get hold of 2.9.5 and try it out on the sim!

J'ai installé les interrupteurs de fin de course, un pour chaque moteur.
Je veux synchroniser les moteurs de manière logicielle pour qu'ils puissent se calibrer séparément et se déplacer de manière synchrone.

L'inversion des câbles est une bonne solution, mais cette machine appartient à mon employeur qui préfère ne pas toucher au matériel (et garder la compatibilité avec l'autre pc avec Mach3)

Dois-je modifier les fichiers .hal et .ini ou est-ce possible avec StepConf ?

I've installed limit switches, one for each motor.
I want to synchronize the motors in software so they can calibrate separately and move synchronously.

Reversing the cables is a good solution, but this machine belongs to my employer, who prefers not to touch the hardware (and maintain compatibility with the other PC with Mach3).

Do I need to modify the .hal and .ini files, or is this possible with StepConf?

Hello Aciera, regarding your “patch,” I would like to know if it is functional? Have you had any feedback? It is indeed a matter of correcting the defect concerning the tapping after the execution of the caxis component.

Ok- so the first thing you suggest to try would be single ended.  Is just setting the jumper DOWN really all I need to do in this case and the axis should (ideally) behave like before? Or will there be more to it?
Well, I will simply try to jumper it to TTL and see if I can run the axis single ended properly or not.

Years ago I remember such "differential converters" on Uhu´s (DC-drives) - these where small and pretty inexpensive parts. But I just knew them for converting A+B channels to A/A* and B/B* , did not need the index in this times....
If I could use such converters to get a differential Index signal out of a single one and so solve the issue I would be fine with it.
Unfortunately I can not simply exchange the encoders as these Fanuc encoders seem to be part of the servo motor and the rear end bearing of the motor.

So I will first try to run the axis with the 7i33 jumpered to TTL, see how it behaves with the single A/B signals and if I can use the index signal then.

Thank you
Sigi

 

Maybe we can combine them?

I need some help here again. I am having a weird issue with my machine. I first thought it has nothing to do with Riocore, but now I am not so sure anymore.

Oliver or someone with experience, could you explain a bit more what the settings in the Stepper dialog under Step mean?

The Step signal for my machine is inverted. I tried to remove the inversion from the step signal, but than the Stepper don´t move at all. Does that make sense??

Can you post your modified kinemaitics file and your ini file?
 

Here's all my files.  I've included .ini, .hal, and kinematics comp file.  

OK, will get the hal file.

I did most of my work on big iron. Watching what happens with an AC vent hitting the top of a machine with a laser will drive you crazy.
Good luck!

Yes, it’s a rolled screw it has error from the manufacturing process. Thomson claims +\- 0.004 per ft / 300mm.

Though it could be mathed out in the SPU if I was using UCCNC or MASSO.

I'm happy to report that building the 2.9 branch (incorporating the merged PR mentioned above) from the LinuxCNC github solved the problem - the mdi-command-NN pins show up and function as expected.  Thanks for the fix!

Nevermind, I forgot how to correctly read and comprehend English.

I would use an RC filter if in a high noise environment

Also not sure from your description,  whats 24V and whats 5V
no 24V signal should be anywhere near 7I92T I/O pins
