Configuration

For the moment there is no graphical interface to modify the configuration, one 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

Even in windows the .bCNC file is created in the user folder. You can reach it easily using the Environment variable %UserProfile% . Hit [Windows key + R] paste %UserProfile% in the Run prompt, then click OK. The user folder will open and there you'll find the .bCNC file. Right click and choose "open with" then select notepad.

With a text editor, open the .bCNC file and modify it according to your CNC machine setup. The sections that may be necessary to modify 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 in 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
