The screen to set the "z" as per Andy (Many thanks!) "keep the Z and set the f-error limits _really_ high" is this the area of the program I should be able to set in the "Servo Info" area?

This is the latest error files. I have looked at them, very close to the prior one. I checked to see if all were set 0 = x; 1 = y; 2 = z: One was not, now (and have checked to see if change was saved, it was).

Many thanks to all for your help!

I think that would be a manual edit of the INI file [AXIS_2] section.

I am a but surprised if you are getting config errors if you are still using PnCConf. I thought you were hand editing the configs.

This seems to hint that you my not be using the config files you think you are using.

The pncconf file appears to be in the linuxcnc/configs director, when you use the "ls" command. I used the conf wizard to see where the file was being saved too, then went to command window. Does this help?

This is the area Andy has talked about. Open this with Mousepad and edit to the preferred settings.

I have edited the ini file (specifically the "z" f-error limits 0 to 50; 1 to 100; and 0 to 50), I don't see any change. There was a comment about if I were editing the ini file of not. If I were to run the Pncconf Wizard it will over right changes to the ini file, I did not use that wizard, but edited va. the mousepad.

Edit: On the 7i77 card there are 3 amber lights on.

many thanks

Now it says that your error is in your hal file "BridgeportLinux.hal" on line:181 that the pin 'hm2_5i25.0.encoder.00.position' was already linked to signal 'x-pos-fb'.

I'm not sure why you keep coming up with these repeated pin links to your encoder pins. If it something your doing manual editing the file, or something you did wrong configuring in Pncconf.
If you could attach the hal and ini files, maybe we could get a better idea of where you may have gone wrong.

Ok, it looks like you have the encoder info for the X axis duplicated for the Z

In the Z Axis section of your hal file change it to this

Attached is an error file that has changed thanks to Todd for all your help! I scanned the attachment you sent and studied to find the differences and keyed in the update manually. I am in hope that this approach may lead to a method to solve the mystery of debugging.

Edit: I only believe the vfd reference (as in pid.s.maxoutput [SPINDLE_9] MAX_OUTPUT); the MAX_OUTPUT needs to say DEADBAND. This is just a guess.

Looks like no comms to the VFD:

Code:

failed to set register P0x0101 to 0x0064 (100): Connection timed out
mitsub_vfd.hal:12: waitpid failed gs2_vfd spindle-vfd
mitsub_vfd.hal:12: gs2_vfd exited without becoming ready

I guess it is on Modbus? Is the VFD configured for Modbus and powered up?
