 · Shrinking Marlin 2.0 – How to reduce firmware size for 8 bit boards and still use a BLTouch and the filament sensor! August 31, 2020 August 14, 2020 by Daniel Kreuzhofer In this guide, I talk about how I got Marlin firmware 2.0 shrinked down to fit on the original Ender 3 mainboard while still supporting a BLTouch and a filament sensor at the same time.

 · It is an optional replacement for the // more proven and much larger QR_SOLVE code base that is being used in the Marlin Code base. // // Using this code as a solution for the Least Squares Best fit by the Auto Bed Leveling code // will save you almost exactly 10 Kb of firmware space.

And I don’t think your firmware is right, cause g28 is supposed to move the bltouch probe to the center of the bed, and yours is not even doing that. Check the GitHub page to see if they have one that is already compile for ender 3 with bltouch. level 2. Original Poster 1 point · 7 hours ago. Thanks for the reply.

I found some guides on reddit with pre-comiled firmware, but they all share the same issue for me: the BLTouch levels a few mm off the front of my bed, thus crashing the head. I noticed you can set the probing boundaries in Marlin so I wanted to try to compile my own firmware (which I wanted to be able to do anyway for the future). I started ...

G28 ;Home G29; BLTOUCH mesh generation M104 S{material_print_temperature_layer_0} ; set extruder temp M140 S{material_bed_temperature_layer_0} ; set bed temp M190 S{material_bed_temperature_layer_0} ; wait for bed temp

A normal bltouch probe during operation is using the needle in the extended position to touch the bed. You will need to calibrate z offset if it is not already done for you. For the Gcode, go into your slicers beginning Gcode script and then add G29 after the G28 command. This will bed level after the printer is …

In Marlin 2.x, they’re now combined in NOZZLE_TO_PROBE_OFFSET. Instructions are in the comments. Using the Creality BLTouch Kit bracket, mine is { -43, -9, 0 }. It’s safer to leave Z as 0 here are calibrate this yourself later. To keep the probe away from the edge of the bed, increase MIN_PROBE_EDGE to 20

 · There is a plug-in for Octoprint called Bed Visualizer that will show you the results of your mesh on a graph, which of course would make random high points stick out. I don’t use BLTouch, I’ve got an EZABL and I’m running the TH3D firmware instead of vanilla Marlin, so there may be some differences for you, but here’s how I’ve got it setup: Warm up bed and hotend to the temps you ...
