Hello,

When you say the printer stop before 140°C do you mean you have an error message on the screen ? if it's the case, you must modify the firmware before upload it on the board!

Hello,

the first thing you could do is to use a bubble level for a good bed settings.
after you could check if the space between each Z axis motor and the couplers are the same.you can use a caliper and manually move the engine when the printer is power off !

Maybe you already do ...

Hello,

Just an important informations ! If you plan to use the last modified firmware, You must modify the maxtemp features for the extruder, because if you plan to print ABS, the printer will stop and make an error !
The max temp settings in the last marlin firmware modified for 3d Touch sensor ...

Hi FishMan,

Maybe some modifications are needed for you printer version "dual extruders"'

Hello,

Finaly I think the good offset for mr is Z-1.0 seems to be good !

Hello !

I test with Z-1.1 and for the moment it seems to have good result

OK thanks for the moment I put -1.4 it seems to work but need time because I print in maximum quality.

Yes Ok I will try that, but now I will set a lower offset because there is not enough pla on the bed.
I will try 1.7, and see if it's good or if I need to set a lower value etc...

Hello NiklasO,
I just want to notice you something, when the offset of Z axis is set to 1.9, there is a bug. I send the print and the X axis go to the right and hit the right of the printer, and return to the center and begin to print but it print in the air... :shock: :shock: :?

Very strange ...

Hello,

I confirm with the great help of NiklasO, My prusa i3 Pro B acrylic works great with the 3d touch sensor and the firmrware is the last new
