Autolevel with BL Touch only scans single row Seasons' Greetings: I recently installed the latest version of Marlin on my CR10S 5 a couple of weeks ago. This was after installing a BL Touch sensor. I configured the example configuration for bi-linear auto bed leveling, at least attempted to do this, mostly by uncommenting '#define BLTOUCH,' '#define AUTO_BED_LEVELING_BILINEAR,' ;#define RESTORE_LEVELING_AFTER_G28,' '. I set the GRID_MAX_POINTS_X (line 1340) to 4. The other features of the firmware upload are working very well (thanks to the help of a couple individuals on this forum). I was wondering where in the configuration file is the 'GRID_MAX_POINTS_X' value assigned to the Y- direction? I would any insights and assistance anyone could share. Thanks for your help. https://reprap.org/forum/read.php?1,879713,879713#msg-879713 Thu, 16 Apr 2026 07:30:33 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?1,879713,882322#msg-882322 Re: Autolevel with BL Touch only scans single row https://reprap.org/forum/read.php?1,879713,882322#msg-882322 MMcLure General Wed, 10 Mar 2021 13:09:39 -0500 https://reprap.org/forum/read.php?1,879713,882319#msg-882319 Re: Autolevel with BL Touch only scans single row https://reprap.org/forum/read.php?1,879713,882319#msg-882319

GRID_MAX_POINTS_Y is typically defined to same value as GRID_MAX_POINTS_X in file configuration.h

#define GRID_MAX_POINTS_X 3
#define GRID_MAX_POINTS_Y GRID_MAX_POINTS_X

It will be alright when I define

#define GRID_MAX_POINTS_X 3
#define GRID_MAX_POINTS_Y 4

I would like to increase number of probing points without loosing centre point (25 points take to long time).

There is some setting in configuration.h to allow change those parameters on printer screen?]]> krzysiekz General Wed, 10 Mar 2021 12:47:25 -0500 https://reprap.org/forum/read.php?1,879713,879726#msg-879726 Re: Autolevel with BL Touch only scans single row https://reprap.org/forum/read.php?1,879713,879726#msg-879726 MKuss General Sat, 19 Dec 2020 23:57:27 -0500 https://reprap.org/forum/read.php?1,879713,879721#msg-879721 Re: Autolevel with BL Touch only scans single row https://reprap.org/forum/read.php?1,879713,879721#msg-879721
