Hi

I'm working with E3D Tool Changer RepRapFirmware for Duet 2 WiFi/Ethernet 3.1.1 (2020-05-19b2).

In order to check if tool is well loaded I implemented this method :

I installed a switch on Tool Graber
I updated config file with :
M950 J0 C"!^duex.e2stop" ; assign duex.e2stop pin to sensors.gpIn[0], inverted and pull-up activated
I updated tpost files with :
if sensors.gpIn[0].value = 0 ;if the microswitch is not pressed...
abort "Failed to grab tool"

Sometimes it works, sometimes not...

More precisely, print is aborted because of "tool grab fail" but this is not the case. The switch is well pressed and led switch on duex5 is ON...

I don't understand. Thank you for your help !

Best regards

Hi

Thank you for your answers.

I finally choosed to use an extruder to run my particular attempt.

I'm trying to extruder untill a change of input state but it do not work.

I know my input works.

I have to launch severall times the macro to get extruding stopped when input goes 1. A sort of manual while loop

Here is the macro code. Why my while loop do not work ?

M83

while sensors.gpIn[2].value = 0
	G1 E0.001 F50

Thanks !
