Overriding the fast jog speed?

[Surgo]

I want to be able to push one of my aux buttons to get a typein to set the fast jog speed, so I can use the controller as a simple power feed. Variables #20301-20308 control this, but it looks in my manual (CNC12 allin1dc 4.14 mill manual) to be read-only. Any way I can set these without having to go through the configuration menu?

I would just use the built in power feed functionality. To access it from the main screen, press F1 Setup -> F4 Feed and then choose absolute or incremental. You'll be able to specify the distance (or position) and the feed rate.

You can find some information on that menu in chapter 6.6 of the 4.14 Mill manual: https://www.centroidcnc.com/centroid_di ... df#page=67

I am aware of this functionality, and I use it often, but there is plenty of time that I just find it cumbersome to use and I want to use the jog buttons.

make a macro to do what you want and assign it to an aux key or just load it like a g code program

Hi cnckeith, thank you for the suggestion. I would like to do exactly that! However as far as I can tell, the jog speed is not a writable parameter from a macro body, but rather read-only. Could you suggest how I could override the jog speed from a macro body?

Have you considered just overriding the jog speed using the feedrate override controls? That is what they are for, after all.

If you use the jog panel pendant, it even comes with a knob you can quickly and easily turn up and down.

If you are limited to using the virtual control panel (VCP), you still have feedrate override control, optionally including quick 25%, 50%, 75% and 100% keys. With a little effort you could make one or more similar keys with whatever percentages you wanted; or -- with some PLC program involvement -- even make one that takes its percentage from a parameter setting.

I will experiment using the feedrate override controls. The reason I was asking the way I was was -- usually I end up calculating an exact speed I want though, so that's why I've been wanting to type it in.

If SlowJog is set to 200mm/min, you can have any speed form 0-400mm/min in 2mm/min steps. That should be sufficient percise.
