Relative movespeed?

[pernilla]

Hi.

Is it possible to set movespeed relative to the distance of a movement?

For example, I have a few distances that are more than 50mm in at least one axis.
Could I somehow tell PC-DMIS to move the probe a lot faster between these points and then go back to normal?

It would save some valuable time...

you could put a movespeed command in program to speed it up and then slow it down. But for 50mm you would probably not see much change. the CMM will ramp up and down for the movement and unless your traveling a long distance you won't see much change.. I would also use Absolute speed under F5 Part/Machine tab. Each machine has its own max move speed. There is also settings in the settings editor for this but I do not remember where.
In F10 there is an acceleration tab that you can play with the numbers.

Acceleration might be what you want, as mentioned at the end of William's post. If you slow the acceleration rate down, then for shorter distances it won't accelerate up to full speed.

All CMM's have a physical limitation to acceleration parameters. Some newer machines simply won't move in DCC if you set the acceleration parameter too high.

Thanks for the info.
I had considered a few of these advices already, just thought there would be some fancy setting I'd missed.
But I'll take a look at the acceleration and manually set a higher speed for longer distances.

the catch22 with this strategy, is every time you adjust prehit/retract and movespeeds, the routine execution will encounter a bit of a delay when it reaches that code. try it out, but keep a close eye on how much time it really saves to toggle speeds mid-routine (as it won't be much if you toggle those speeds often).
