ok
i change the values an it is the first time i have both y0 and y1 enable and stand still
i can not home the machine because of a problem with the z axis break
when i try to jog the y axis only the y0 motor is rotating, the acceleration on the display is moving, but not the y axis value
where to look for this
Is the display showing 1234 or XYZ ?
You won't be able to jog the gantry until you are in "World Mode" (XYZ) and you won't be able to go to that mode until you are homed.

in the display is X Y Z C (for the c i modified the INI file as you suggest)
Yannis wrote: how can i change the A axis letter with C at the display of the axis
thanks for the help
andypugh This is configured by a combination of the [DISPLAY]COORDINATES and [TRAJ]COORDINATES INI file settings
i read that to change from X Y Z C to 12345 there is the $ in the view section

update
after i change the TRAJECTORY of the INI file from X Y Z C to X Y Y Z C the jog goes like this
up key Y0 +(values don't change on the display)
down key Y0 -(values don't change on the display)
left key X+
right key X-
page up Y1+ (values change on the display)
page down Y1-(values change on the display)
i wonder where is the Z+ Z-
also i wonder how to configure keys on the keyboard for the C+ C- jogging

hi
i try to home the machine manual
to do that i zero all the values in the home sequence in th INI file
i zero the X and Y everything is OK
when i try to zero the Z i have the first error for Joint3(why that happens in manual Z homing?)
when i try to zero the C i have the second error Joint3(the C is configured as 4 Joint)
any suggestion where to look for this settings?

Do the Z and C axes jog properly? The problem might be that the encoders and the PID disagree about which way is left and which is right.

Hi
i manage to home the machine and after that thinks are going better but still have some problems
after i home the machine the x axis can jog until -0.10 and after that stops and that is great because it is the -x limit
and after that can jog only to the positive area:laugh:
Y axis is stop when it reach the -0.10 but after that pop up this error
i look in the INI file but i can not understand the problem
any suggestions??
thanks

The misconfiguration may be that you have two [AXIS_Y] sections in the INI, and the first one (which is what the system will find) does not contain any limits.
The machine has definitely gone past the limits as far as LinuxCNC is concerned. Is this physically true?
It might be that the acceleration limits that LinuxCNC is using do not match the real limits, and so so the axis moved further than LinuxCNC commanded it to.
