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 :

https://forum.e3d-online.com/threads/improving-homing-safety.3448/

1. I installed a switch on Tool Graber

2. I updated config file with :
   M950 J0 C"!^duex.e2stop" ; assign duex.e2stop pin to sensors.gpIn[0], inverted and pull-up activated

3. 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 !

@phaedrux Thanks for you reply.

But I think I will get the same as M592 : il will be proportional.

I need something not proportional :
10.1 => 10.0
20.1 => 20.0
30.1=> 30.0

Hope I'm clear

Thanks !

Hi everybody

After several tests and adjustements, I get, on a CoreXY e3D toolChanger a difference betwenn X and Y dimensions.

When I print x 10x10x10 mm cube I get :
on X : 10 mm
on Y : 10.1 mm

And for 20x20x20 mm:
on X : 20 mm
on Y : 20.1 mm

I learned that with a CoreXY this issue is due to belts tension/aligment but I tried severall on this without success.

That's why I was looking for a software compensation.

I tried M579 but this seems to be "proportionnal".
So this does not help me.

Is there a config.g configuration to tell : "print Y axis -0.10 mm" ?

Thanks !

Best regards

interesting, thanks !

I found the problem... finally a hardware issue !

Hi everybody

For a specification application, I need to home a new "axis" different from X, Y or Z.

This "axis" is driven by a stepper motor.

How can I declare this new axis and run homing on it ?

Thanks !

Fiannly it worked with :

M308 S0 P"temp0" Y"thermistor" T100000 B4725 C7.06e-8 
M950 H0 C"out0" T0 ; create heater and map sensor 0
M140 H0                                                   
M143 H0 S100                                       

Thanks !

Yes I changed to temp0 on board...

Ok, thanks.

Tried this without success after changing pin sensor to temp0 :

M308 S0 P"temp0" Y"thermistor" A"Bed" T100000 B4725 C7.06e-8    ; Set thermistor 
M950 H0 C"bedheat" T0                                      ; Bed heater
M140 H0                                                    ; Add heater to bed after RRF3.01 RC10
M143 H0 S100              

Hi everybody

I don't find what I'm doing wrong...

I'm trying to connect an heated bed to Duet 3, Thermistor on IO PIN4

Here is the code :

M308 S0 P"io4.in" Y"thermistor" A"Bed" T100000 B4138 C0   ; Set thermistor 
M950 H0 C"bedheat" T0                                      ; Bed heater
M140 H0                                                    ; Add heater to bed after RRF3.01 RC10
M143 H0 S120                                               ; Set temperature limit for heater 0 to 120C

I get -271°C on DWC

I checked the thermistor (about 120k ohm at room temp).

Thanks by advance

Thanks, it works !

Could you please tell me where I can find all the object models I can work with ?

Best regards
