Configuration

For the moment there is no graphical interface to modify the configuration, it will be created one in the future.

The easiest way is first to launch bCNC and close it. The first time it will create a clone of the bCNC.ini in your $HOME directory as $HOME/.bCNC

Open with a text editor the .bCNC and modify it according to your CNC machine setup. The sections that maybe need to be modified are:

[Connection]

baud = 115200
port = /dev/ttyACM0
pendant = 0/1 ; 1 to start automatically the pendant web server
pendantport = 8080 ;specify the port where bCNC will listen for browser
openserial = 0/1 ; allow to automatically open serial connection to grbl upon startup

[CNC]
(CNC section is also modifiable from Tools Tab in bCNC software)

units = 0 ; 0=mm, 1=inches
acceleration_x = 25
acceleration_y = 25
acceleration_z = 50
; acceleration in units/s^2 for time calculation
feedmax_x = 3000
feedmax_y = 3000
feedmax_z = 2000
; maximum feed rates in units/min for time calculation
travel_x = 200
travel_y = 200
travel_z = 100
; maximum travel of your machine in the three axes
These values will define the WorkArea int the main canvas (enabled/disable from View-->WorkArea)
Be aware: for historical reasons values are always referenced from top/right corner even if your home switch position is in the bottom/left corner.
round = 4 ; rounding accuracy in decimal digits .dddd
accuracy = 0.1 ; accuracy of displaying arcs (maximum allowed sagita)
startup = G90 ; startup g-code to send to machine before executing any program
safe_z = 3 ; safe z height on free moves
spindlemin = 0
spindlemax = 12000

; spindle maximum/minimum in rpm/min
