Wow!!!

do you have a servo driver that can work in two independent modes step/dir (position), and analog input (velocity mode)? take a look at the video, I did it by introducing ``A `` as standard axis for changing the position, and the motor rotates like a classic lathe through the gcode M3 ``S``command by analog signal.

A bad 40 pin cable would cause different types of errors
(the 7C81 itself would cause errors)

Might be bad 7C81, bad 7I76, or bad 26 pin cable.
mis-jumpering is unlikely to cause damage.

Do the 7I76 step/dir outputs work? That would be a quick test
of the firmware, cable, 7C81 and 7I76
 

Cant do this anymore bye all wrote:

Ahh I messed up there my apologies.
 

I also had forgotten about the pin file options and that most of the
newer ones show daughterboard pinouts. I only noticed when I looked
at the actual distributed files.

The difference is this:

mesaflash --device 7I97t --addr [card_ip_address] --readhmid > 7i97t.pin

mesaflash --device 7I97t --addr [card_ip_address] --dbname3 7i85 --readhmid > 7i97t.pin

I edited num_encoder to be 1.
I just used pncconfig to create a new 5i25 file set and then made the changes for the 7c81.
I am still getting the error message on "hm2_7c81.0.7i76.0.0.output-00" that this pin doesn't exist.
I think I will order a new 40 pin cable to see if that fixes the problem.
Is it possible that the 7i76 could have been damaged when the power jumper was misconfigured?
The other thing that I could try would be to take the 5i25 files over to my machine that actually has a 5i25/7i76 pair and see if it will load there.
If I sent you the .ini file and the .hal file could you see if there is anything obviously wrong?

Shouldn't be much different from a hal_button,
open panel in glade add 'HAL_ToggleButton' and assign some ID (eg 'hal_togglebutton1') to it, save
Start config, open 'Halshow' and the pin should be visible as 'testpanel.hal_togglebutton1'

Ahh I messed up there my apologies.

I'll appreciate it. I'd like to connect via P1 because i leave it for encoders in future and time has come (based on other users experience). I already use P2 and P7 for communication with mx4660.I've tried to add configuration to pncconf but TXEN2 TXDATA2 and RXDATA2 don't want appear, do someone know what I'm doing wrong?

This is great now. I'm using the test panel you sent. I can see the normal buttons in Hallshow. However, Toogle buttons are not visible in Hallshow. Can you teach me this too?

"MAX_ACCELERATION = 5000 "


try with less acceleration ...

Open the panel in glade, insert a button, add 'on_destroy' to the 'released' signal (not sure about the exact signal name but it should be fairly obvious)

How should I follow to save when I press the save button?

I have no idea how to make the save button

There is nothing that will automatically save in case of a powercut, so you will have to do with a save button. Not sure about the shutdown procedure as that usually requires elevated privileges.

Can gmoccapy be closed first and then the computer shut down when a button is pressed on the machine? If such a thing is possible, data can be recorded in this way.
