Facepalm
Thank you all for your input
And thank you whosrdaddy for the solution. i tried extruding without the heatbloc connectet.
And filament extrudes as it should. so after a cleanup it should work fine .

Thanks again

And it has worked fine for me too until i updated firmware ???? it makes no sense i know . But its a fact. I even tried re uploading the firmware with no change
So somewhere in my files there is a little gnome teasing me

Pancake? dunno . its the motor delivered with the titan ( e3d ) 26 mm thick . And i run on 12V on my system

my problem is that it dosnt extrude enough filament . only about half.
It's a 9 degree stepper and i have had it running fine.

measuring 100 mm filament and mark it and tell it to extrude 100 mm. it only extrudes 60 mm with this setup ?

i tried swapping M92 and M350 as sugested. Still doesnt change a thing ?

the fun part is that it worked fine before ??

After i upgraded to latest firmware, my extrution is way off .

Nomatter what i set the step pr mm to, it dosnt change a thing ?

@dc42:

Which firmware version were you upgrading from?

1.1.9 something

What am i doing wrong ?
I installed the 1.20RC3 and webserver
but lost wifi signal ?

SENT: M115
READ: FIRMWARE_NAME: RepRapFirmware for Duet WiFi FIRMWARE_VERSION: 1.20RC3 ELECTRONICS: Duet WiFi 1.0 FIRMWARE_DATE: 2017-12-16

I got the Mini IR board on my Creality CR-10
I have the mesh bed leveling working fine.
But i would like to use the sensor as Z endstop .
I am guessing i should have the bed center as home for starter
so i dont go outside the bed when homing Z
any sugestions ?

Works great on my CR-10-4
Using the original case ,and like you , i raised the board about 30 mm for airflow.
I did swap the original case fans for a single Noctura 60 mm fan , and that keeps it just aound 30 degrees .c
I use the 5" PanelDue . And i must say i really love this setup . Really quiet printer now

Thanks for a great job on this g code
