Sebastian,

>> A couple of comments on that config:

It looks like it was based off an older, somewhat buggy hm2-servo config.
Specifically, the [AXIS_*]OUTPUT_SCALE is not used by the hm2-servo.hal
file. <<

What I posted is the copy I have, it is about three months old, which is why
some of the settings are somewhat "soft". The PID PID values, ferror, etc.
have been tweaked since I got this copy.

>> The [AXIS_X]MAX_VELOCITY is used in the hal file as pid.X.maxoutput,
which i think is wrong.  Oops, i just noticed that the standard hm2-servo
config does the same, i'll check in a fix for that. <<

I saw that you checked something in. I will go take a look.

>> The [AXIS_*]INPUT_SCALE values look strange.  Is that really what the
encoders are producing? <<

The motors are all the same 600 Watt DC servo (5' x 10' table). Each has a
different gear ration, Z is approx 20000 CPI, Y is 12000 and X is 6000 (not
exact, too lazy to look up).

>> The [AXIS_*]FERROR and MIN_FERROR look very large to me.  Is it really
acceptable for the machine to be a quarter inch off while feeding? <<

Old values, see above.

>> In hm2-servo.hal, the hostmot2 driver is loaded with all debugging flags
turned on, that's probably not needed.  Oops, i just noticed that the
standard hm2-servo config does the same, i'll check in a fix for that too.
;-) <<

I am not sure whether those are on in the running configuration, I will
check.

>> Wow, this machine has a GlueGun?  :-) <<

Two actually. Well it worked a lot better on paper than in practice. :) It
never got to the point of working reliably and has been basically abandoned.


>> Yes, i think trying it without the joystick would be a good experiment to
do. <<

I already told them to try that, I am waiting to hear back.

Thanks,
Eric
