RRF 3.1.1 Probe Issues
-
@CaLviNx Thanks
-
@CaLviNx how would that look in the config.g?
-
@CaLviNx This is my current M558:
M558 P5 C"zprobe.in" H5 F120 T6000 ; set Z probe type to unmodulated and the dive height + speeds
How do I edit that to probe twice?

To be honest in RRF-3 im not exactly sure how you go about getting any subsequent probe to be of a differing speed to the initial probe, I would surmise there is some young pup of a computer whizz out there who can whip up some conditional g-code to do what you are asking.
Me myself and i would start by trying multiple copies of M558 both with A1 in the command but differing feed rates, the worst that can happen is that it doesn't work and you need to work out another solution.

M558 P5 C"zprobe.in" H5 A1 F600 T6000 ; set Z probe type to unmodulated and the dive height + speeds M558 P5 C"zprobe.in" H5 A1 F120 T6000 ; set Z probe type to unmodulated and the dive height + speeds
Thats what i would try first but as i said it might not be the right way to do it.

@CaLviNx Thanks for the help mate, I will give it a try.

You need to add the A and S parameters.
If you wish to force it to always probe twice use A2 S-1. It will average the 2 readings. If A was 5 it would average 5 readings, etc.
If you wish to have it try to obtain two consecutive readings that are close in value you would use something like A5 S0.1
With those values it would would probe up to 5 times until 2 readings were within 0.1.
If it failed to obtain 2 readings within 0.1 it would average the 5 readings.

@fcwilt Thank you! That's perfect!

Yes that works to do multiple same speed probes but doesn't answer his initial question
it would probe once fast and once slow in each spot, now it only probes each point once? Has anyone else noticed this and how can I fix it?
-
@CaLviNx Thanks for all your help too mate, I don't really need them to probe at different speeds, just having it probe twice will also work for me.
-
Even if this is not really required by you, the point it raises it would be interesting to find if there is a solution.
-
at the moment, I believe the solution you're using is the only one @CaLviNx
I use the same thing. I think it's on the "list" to be looked at to allow different homing speeds i.e. fast and slow. -

Well as you have determined the F parameter controls the probing speed.
That would seem to qualify as a solution.
When homing using endstop sensors the typical code has always include changes in the F parameter for the G1 commands.
