New A20M Model ?

[psxsnake]

I have same model variation.
Where you connect bltouch?

You have the 5 pins at the top of the small board, just under the big connector

Hello

I have my A20M since a week now ... and only did two print

I bought the 3dTouch ... but when looking the way to do on my new version ( V4 ) of the A20M ... and all the issues ( failure ) I see about it
I just wonder if I should not return it , and buy the original BLTouch ...

What do you think ?
Good idea ? useless ? bad idea ? ( and why )

They changed the hotend slide, appearently.

Instead of flexing off the nose you can also replace the endstop holder with a modified one which places the endstop switch further left.

I use the one included here: https://www.thingiverse.com/thing:4257275.

Hello

Could someone provide me the values of the setting as it is "out-of-the-box" for the A20M V4 ?
Especially the one in menu "Control / Motion"
- Velocity
- Acceleration
- Jerk
- Estep

Thanks a lot

for the story summary : ( see my point about estep below )

I tested my A20M out of the box , with correct prints
I installed my 3dtouch , following the Geeetech explanations ( video )

To get sticking prints to the plate .. I had to fine tune the z offset ( as documented and explain in lots of places )
I did it with the
application "pronterface" (https://www.pronterface.com/)
following this video ( https://youtu.be/y_1Kg45APko

( I did it a second time , as it was a little bit too low / touching the bed ... )

The next issue was that all my prints ( even the gcode already tested ) were really under extruded

I did the estep calibration ... I had to change the value from 395 to 931.6 ( yes ... that much
to get rid of the under extrusion issue.
