IR Probe w/wo bed.g?

perolalars

Hi
I am in the finalizing settings of my diy corexy printer. I have an ir probe from dc both for z-axis homing and bed calibration. I have gotten the homing working but I cant get my head around bed calibration.
Should/must I have a "bed.g" to store my settings in or does it work with settings in "config.g"?
All the info about "bed.g" seems to be for delta printers or am I wrong?
How should the code look both for probing the bed and to make use of the collected probe data?
Still quite new to this so plz bear with me!

Hi Per,

You can either have a bed.g file or set the coordinates in your config.g using M557 (see here http://reprap.org/wiki/G-code#M557:_Set_Z_probe_point)). Either way, you define the xy coordinates of the points where you want to probe the bed. Personally, I prefer to use a bed.g file. I think best practice is to define the points in a clockwise direction, usually starting from front left.

The bed.g file for a Cartesian or CoreXY printer is described here https://duet3d.com/wiki/Configuring_RepRapFirmware_for_a_Cartesian_printer#Bed_probing_file. Whether you use bed.g or M557, the probe points must be in a clockwise order around the bed starting with the point nearest the [0,0] corner.

Okey, think I will go with the bed.g solution then.
Thanks for clarifying
