I built a 3d printer about 10 years ago and have been running it with a smoothieboard. I now have converted the printer to a cnc mill . I tried just connecting it to ugs and it wouldnt connect, no surprise. I downloaded the cnc firmware but cannot find the cnc configuration.txt file to go with it. I keep getting a Grbl has not finished booting. Can anyone tell me where to find the configuration file on the smoothie website?
It thinks it is talking to grbl but you are still running smoothieware, do I understand correctly? (there is no configuration file for grbl)
I have the firmware firmware latest .bin flashed on the smoothie board. From reading the smoothie website 1000 times I do the cnc part just like the 3d printer part. I flash the chip on the smoothieboard with the firmware and then I put a configuration.txt file with it on the sd card. I then write the commands in the text file to tell the firmware what to do. I cant find the cnc configuration text file on their website. I can find the 3d printer text files but not the cnc one.
There is not “the cnc one” — you write a configuration file that describes how the board is connected to your hardware. There’s no one magic configuration file.
Ok thats what I figured after looking around last night. So I’ll just start copying my 3d printer config files over to the new sd card and leave out all the things I dont need.I have several other questions. On their website they have a special cnc build of the firmware but it says its for 3 axis only. My core xy machine has 2 stepper motors for the z axis so I’m thinking that will not work as it will disable one of my steppers I need. They have another cnc firmware but I dont see in the documentation how many axis it has. Could I just use the 3d printer firmware instead to keep all the drivers on my board active?
Another question is it states to put “grbl_mode true” in the config file. Do I just put this at the top somewhere and do I need any other config commands to go with that?
I have a few other questions but I need the universal gcode sender to see my board first.
Please read getting-smoothie [Smoothieware]
And
grbl-mode [Smoothieware]
And if it applies, 6axis [Smoothieware]
I have M3 inslaved to M5 with jumpers. Do I still need to compile for 4 axis?
If my logic is correct I should be fine with the 3 axis cnc firmware.I have M3 and M5 slaved together with M5 disabled in the config and jumpered together on the board. Im guessing the cnc firmware uses M1 M2 AND M3 as the 3 axis.
How many axes are you going to address in Gcode?
G1 X1 Y1 Z1?
G1 X1 Y1 Z1 A1?
I’ve still got to learn the g codes. It will have 3 axis though
I downloaded The latest cnc bin file and the latest configuration file. I put all my steps per mm in and took out any references to extruders or hot ends. I took out anything 3d printer related. Open universal gcode sender, set to smoothieware and hit connect. It connects to the com port fine but still the same " Grbl has not finished booting" message if I try any of the left menu buttons. The jog buttons are grayed out. I went back into the config file and put in " grbl_mode true" and still the same thing…

I’m starting to think these two just arent going to work together. I picked that program because it seemed popular on the web. Any advice on a good free program that would work with a smoothieboard?
bCNC seems to be working. It connected and I can jog the machine. Thanks !
