Probe deploy in loops

sinned6915

I am working on a probe_find_Z macro. I started rolling my own, then found owendare's and wanted to try it with the while loop instead .

the odd behavior is it will pick up the probe and then the system will complain the probe is already deployed before probing.

normally, I try to wrap any sucessive probing with M401/M402 sequences. I can not figure out where its checking the probe status and erring out.

do i need another while loop to check the probe deploy token?

here is the output-

deployuser token = true
Probe State = 0
deployprobe start value Probe already picked up.  Manually return probe to the dock

from this macro-

; Probe the same spot 10 times to test repeatably.

M291 P"Probe will be tested 10 times and return mean and standard deviation. Ok or Cancel?" R"Begin probe test?" S3 ; User must click OK or cancel.

; Check if any axis hasn't been homed, and home it if required
while iterations < #move.axes ; By putting # in front of the array object, it will return the number of configured axis
	if !move.axes[iterations].homed ; if this axis is not homed
		G28 ; home all axes
		break ; no need to continue this loop
	else
	; All axes are homed, but may not be in a point that can be probed. Move to the center of the area that can be probed.
	M401
	G1 X{(move.compensation.probeGrid.maxs[0] - move.compensation.probeGrid.mins[0])/2} Y{(move.compensation.probeGrid.maxs[1] - move.compensation.probeGrid.mins[1])/2} Z15 F6000
	M400
;now begin our probe test
while iterations < 10
	if iterations <9
		G30 P{iterations} X{move.axes[0].machinePosition} Y{move.axes[1].machinePosition} Z-9999 ; probe the current position and record the offset
	else
		G30 P{iterations} X{move.axes[0].machinePosition} Y{move.axes[1].machinePosition} Z-9999 S-1 ; probe the current position and calculate the deviation
M402

this is mine- half done, but with static probes instead of a loop.

@sinned6915 what type of Z probe do you gave; what M558 command have you used to configure it; and what is in your deployprobe.g and retractprobe.g files?

@sinned6915 I just checked the code. The M401 command does not check whether the probe has been deployed already, it always runs deployprobe.g. It then sets the "deployed by user" flag so that G30, G29 etc. commands don't attempt to deploy/retract it. Similarly, M402 always runs retractprobe.g and clears the "deployed by user" flag.

So I suggest you avoid calling M401 in that while loop, or arrange to call it only the first time.

You can read the state of the deployedByUser flag from the object mode, under sensors.probes.
