Can you attach your mesambccs file?

this is my code for reading and writing using MESAMBCCC
I can read and write data without problem in case i use one register but when i try to write on a multiple registers i faced a lot of problems i captured some of them on the attachments

The stepgen is in the FPGA card so it will show up regardless of whether
the daughtercard is present or not (the daughter card just buffers the stepgen signals)
 

Hi stenly,

could you tell me how you got on with it? Also, if you have a working CSV - Ethercat, I would be very happy if you could send it to me. I have some problems getting it to work.

I can get the drive turned on (C2000 + EC01 + PG01L) , but I can't set the speed. I can't find anything that works.

Thanks. BR,
Pavel

The thing is, it worked before. So i would be weird that i would need to change the jumpers.

To make some progress i swaped to a different computer with a 6i25. This one works with the cards. So the problem is not with the 7i77 or 7i76.
Im planning to put the 5i25 into a different pc, one that is a bit newer. I have reason to believe that the pci slot is 100%.

However, like you said it can see the stepgen but not the analog. i also found that weird.

Thanks

I have not used the anglejog component other than playing around with the sim config. As I understand it the 'scale' factor is used to avoid stair stepping in the tool path. Maybe the original discussion can give you some more clues:
forum.linuxcnc.org/38-general-linuxcnc-q...mode?start=10#253252

[edit]
I would tend to use the default values used in the sim config and adjust the
'max_vel',  'max_accel' pins (and possibly 'accel_fraction_in' for fine tuning) 

Can you post you current hal file? 

This really makes no sense.

It sounds like either some basic error in the hal file or a
continuously changing index signal

Also: Is the encoder position cleared to 0 when you set b-index-enable?

This topic has been tainted entirely so i will try to separate it into two topics later, now, what should the topic title be ?

The most likely problem is that you have 'anglejog.current-scale' = '0'.

Note that the 'anglejog.scale-in' value is only sampled when 'anglejog.enable-in' is false. (See 'Notes' in the man page linked above)

You may want to have a look at the anglejog sim config :
configs/sim/axis/anglejog

 

 

I think I'm almost there...
I have motion, however I don't understand the scaling, at the moment with the attached settings, 1 click of the MPG, yields 7.040" of actual Z axis movement.

Changing the scale value, does not change the distance moved it does change how fast the carriage moves; with 1 it's very fast, with 10 it's fast, and with 100 it's a nice comfortable jog speed.

I'm not sure how to correct the actual scaling?
   

My button never change when color , is always RED . same when i click on "set"

Seeing the encoders or stepgens just means the 5I25 configuration contains
encoders and stepgens. You would need to verify they they work by actually
testing the encoders/step/dir signals. As tommylight suggests, sounds like a
jumper/connections issue.
 

Moved to "driver boards".

What does mesaflash --readhmid return?
Check the manual on how the jumpers should be set
Check the DB25 cable if it has continuity between all pins, some cables have only 8 wires so wont work
Check the power supplies, 7i77 must have 5V and 24V power for everything to work
And make sure the 7i77 is connected to the correct header on 5i25, there are firmwares that change ports, for some reason...

Currently in my phone so I cannot add configs and such.
However, I redid the wiring on my devices and afterwards I no longer can connect to it. It cannot find the analog part of the 7i77. So the 5i25 is set up as 7i77 + 7i76.

The leds look alright and I have nothing to believe anything is broken. I can find Stephens and encoders through halrun. This makes me believe that it can see the cards.

Does anyone have ideas? What is wrong or I could do to troubleshoot?

Compress your config folder and post it here.

I'm doing some boards up that will use shift registers so I will do some testing, and see what happens. Worst case is I design it so that the shift register outputs aren't enabled until Linuxcnc is started and communicating with the FPGA. 

Cheers.
Russell.
