Marlin-Ai3M VS Marlin-AI3M-BLTouch

Then I tried the same method with a different firmware from GitHub which is Marlin 1.1.9. This correctly displays I send M115. But the screen is still unchanged.

I use this custom Marlin firmware by davidramiro: https://github.com/davidramiro/Marlin-Ai3M/releases/tag/v1.4.6

To make the drivers work properly, I upgraded the Firmware of my Printer with: https://github.com/davidramiro/Marlin-Ai3M.git

Okay this is driving me nuts. I picked up an Anycubic I3 Mega second hand. It's got the github marlin firmware, some aftermarket drivers (bigtreetech tmc2208 v 3.0, normal wiring), what I believe to be the Mega S extruder (tension spring, totally enclosed) and no further mods as far as I can see.

first one was this one https://github.com/davidramiro/Marlin-AI3M, that have PWM and more importante PID control.

Also, you can find some custom Marlin firmware with BLTouch support and other things on Github. I use https://github.com/knutwurst/Marlin-2-0-x-Anycubic-i3-MEGA-S but https://github.com/davidramiro/Marlin-Ai3M also exists. Just make sure you get the right firmware if you go down that route.

It's an anycubic i3 Mega s and I have just flashed the Marlin Firmware from here. https://github.com/davidramiro/Marlin-AI3M I am using 1.75 PLA (Sunlu) and that was printed at 185C bed at 60C Printed at 50mm/s Retraction distance 10mm @ 60mm/s Slicer was Cura

I recently installed a BLTouch. I got the sensor working using this firmware https://github.com/MNieddu91/Marlin-AI3M-BLTouch. The G29 calls seems to work correctly and I can view the offset values when calling M420 V1. I posted a screenshot of the values that were measured. However it looks like the mesh is not actually being applied to the print as the left side looks like the hot end is much closer to the bed than on the right side. Is there another step in the start gcode I need to do to actually have the bed level values be used when printing?

Try this one https://github.com/MNieddu91/Marlin-AI3M-BLTouch it's a fork of that one

Hi, I have been trying to install a BLTouch into my Mega S for the past 2 hours, and whenever I plug in the black and white wires, it shuts off and will not work. The printer is on Marlin, and works whenever the black and white wires are plugged in. I am currently following this guide, https://github.com/MNieddu91/Marlin-AI3M-BLTouch/wiki/Installation-BLTouch, does anyone know how to make it work? any help is greatly appreciated.

When you get your BL touch you can switch to this version which is the same build bit with BL touch support https://github.com/MNieddu91/Marlin-AI3M-BLTouch

I'm running this firmware: https://github.com/MNieddu91/Marlin-AI3M-BLTouch
