3.01RC12 on Ethernet + Duex5, M291 S2 nonblocking inside IF loop

[techild]

Potential bug: M291 S2 option is blocking and working correctly in Duet Ethernet + Duex5 as long as it is outside of a conditional IF statement. Once it is used inside an IF statement, S2 option is no longer blocking.

RRF3 notes only states only nonblocking M291 options are available in Duet3+SBC.

Thanks, added to my list to investigate.

Can you post the macro?
Board: Duet 2 WiFi (2WiFi)
Firmware: RepRapFirmware for Duet 2 WiFi/Ethernet 3.01-RC12 (2020-05-06b1)
Duet WiFi Server Version: 1.23
Duet Web Control 2.1.7

M291 S2 is definitely blocking inside macro when run from DWC or called with M98
Haven't tried running withing a print file.

while iterations < 6
	if mod(iterations+1,2)!=0
		echo "odd number"
		M291 P{iterations+1 ^ " is an odd number"} R"Odd number" S2
	else
		echo "even number"
		M291 P{iterations+1 ^ " is an even number"}  R"Even number" S2
	G4 S0.5
if !move.axes[0].homed
	M291 P"axis is not homed (IF)" R"check" S2
elif move.axes[1].homed
	M291 P"axis 1 is homed, but not 0 (ELIF)" R"check" S2
else
	M291 P"axis is not homed (ELSE)" R"check" S2

Uhm, odd, its working for me now as well. Could have sworn it wasn't behaving correctly yesterday. Thanks for the confirmation! Will have to go back and see what i did wrong.

Edit:

This is what was tripping me up. I wasn't seeing the M117 message pop up on the PanelDue after M291, so I thought it was running ahead.

elif state.currentTool = 1
	; SOME CODE HERE
	M300							; beep
	M83 							; set extruder to relative moves
	G1 E-250 F2000					; unload fast
	M300 							; beep
	M291 P"Please clear filament guide tube of old material!" S2
	G4 S1							; Wait 1 second
	M117 "Start feeding filament into LT Tool!"
	G4 S2							; Wait 2 seconds
	; SOME OTHER CODE

@techild
Glad you're sorted.
Might be best to mark thread as solved.
