Sorry!

I was talking about the G-Code G64.
It allways shows up whit the startfile of axis GUI.

At the Moment i edited the INI to load another File with G61 set.
But i totaly wona avoid G64.

And is it possible to use the encoder as DRO only?
I use direct Step/Dir instead of +-10V and my real difference after a long loop testrun was about 0.002mm.

Or even better, as an emergency Stop when a diverence (maybe +-1mm) hapens + DRO

There is another way, using RS274NGC_STARTUP_CODE

If you set the GUI to display actual position rather than commanded position you might get what you want.

Not knowing what you are doing, I'm not sure why you would want to avoid G64. It is an incredibly useful tool especially when used with the Pxx deviation limit parameter.

I belive G64 may become handy in many situation.
But im doing alot of custom mode items. So i dont wona have to think about every "tweak" each startup.
Especially previously/accidently set G parameters are able to destroy a 1.000$ Part in Seconds.

About the Encoder as DRO.

So if i wish, to "show" the encoder only i have to do something like this?
Code:
net x-pos-fb-enc <= hm2_5i25.0.encoder.00.position net x-pos-fb-enc => axis.0.motor-pos-fb net x-pos-fb <= hm2_5i25.0.stepgen.00.position-fb net x-pos-fb => pid.x.feedback

Because i noticed, beside PID, Axis also looks for "joint-errors" somehow.

Hm,..

Im running into a Problem somehow.

Up to 2m/min everything is fine.
Above 2m/min i run into joint following error at the "Down-Ramp"

Up-Ramp and Movement up to 30m/min everything is just fine.
But as soon as i lift my Finger from the Arrow-key... GANG, fullstop.

If you want to only have the DRO you can set the f-error in the INI to greater than the machine travel, and then the following-error will never trip.

(This is assuming that having an alternative config only for manual use is acceptable)

Note that you can have two configs in the same directory sharing all the HAL and tool table files etc. Just make a copy of the INI with a new name, and call it something like "manual_dro.ini"
This INI file would probably want to exclude some of the HAL files that enable motion, or potentially contain a reference to an extra HAL file loaded last that disconnects / disables things.
