Gantry machine progress

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 will check that Monday morning
thanks

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.

Hi
i have check and the INI file of the Y and the are there
