Been trying to get the estop and machine on circuits working properly today with help from marks mh400e information which he kindly sent to me. 
just wondering if the older mahos have the same estop chains and components?

Help me please????I have spent 3 days trying to get linuxcnc to power on the Maho with no success.Where i am at. With linuxcnc open and the machine released from estop i can manually latch relay 19k1 by holding on the contactor with a screw driver. When i do this the whole machine powers up and everything is working perfectly. the drives are enabled the linear scales are reading correctly. the door open closed switches are all working correctly but the x and z servos are rotating slowly but smoothly. Then when i update the hal file to electronically latch 19k1 with f2 it will not hold and drops relays straight away.

.... i can manually latch relay 19k1 by holding on the contactor with a screw driver.
Never smart to do that to machines.

.... but the x and z servos are rotating slowly but smoothly.
This means that LinuxCNC has no control over the servo drives, usually incorrect or missing wiring, like are the encoders wired to Mesa and do they work correctly counting up/down on the LinuxCNC DRO ?

Then when i update the hal file to electronically latch 19k1 with f2 it will not hold and drops relays straight away.
What error does LinuxCNC show when that happens?
I would bet it shows "joint.n.following-error" as noted on my second reply.

You are working on a complicated machine, so it is imperative to follow instructions strictly and as listed in priority.
See this for wiring and testing:

And for network and WiFi to work at the same time, see here

thanks tommy for the reply. regarding pushing the contactors, i hade to prove that the machines electronics are working properly and that the push button 3sh1 which powers 6a1 safety relays temporarily until 19k1 is latched was working correctly. all the safety systems of the machine are not be touched. similar to Rotarysmp's mh400 retrofit.

Linear scales are reading correctly on the dro and as you can see from the ini file posted above i have accurately populated the scales values.

regarding the indramat drive signals i bet your right and i know i have something wrong here but im having trouble figuring out what. +10 and -10 wires are connected to the 7i97ts and i have left the original drive enable circuit untouched as this is handle by a contactor called 7k1 whose coil is pulled when 19k1 relay has been latched leaving mahos estop and error indictor logic untouched. can this work?

linuxcnc does not show joint.n.following-error but it did before i added an extra ground from +10-10 cable sheathing cables sheathing.

contactors fire and back to estop errors. i know im doing something wrong but writing this and try to explain whats going on might help. thanks for your help

Sounds like you have two separate errors.to clarify, when you try to start the machine contactors are closing? If so, which?
For the servos, can you post how you connected the indramat +/- 10V wires to 7i97T terminal block?
