here is an extract of the boot messages with 
drvMAXvdebug=10, while autosave writes 
-5.55123456e-06 to the ERES-field.

This command (ER-180140,52359) does not work for
current firmware versions.

No, this is the

Re: 2 MAXv problems

Hello Jens

There has been a recent (R6-4 and above) fix to prevent intermittent 
MAXv command
errors from occurring when User Units are turned off, but the motor 
record has not
issued negative encoder ratio commands for a long time.  Are you using a 
really old
version of the motor record?
