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
From version 0.4 parameters equal to default will not be present in user configuration file. So it's common have some sections missing from your file.
