Corexy sandify Error 22 Gcode undefined feed rate

ZenXY Software

Trying to run a sandify gcode on fluidnc and I get “Error 22 undefined feed rate” and it looks like because sandify does not have a F code after the x y, If I insert an F code it runs. Is there anything I can do in fluidNC to pre-define an F code?

I generally put some commands in Sandify’s start code box.

Mostly, it homes the machine, and has a small movement G1 X1 Y1 F600 which sets a feed rate, and the controller will keep that rate from there on out.

On my first table, sometimes the table would lose the ball after homing Y, so it would home the machine without the ball (I had the machine set up so that the magnet was centered under the edge of the table, where the ball could not go.) Then what I would do is add:

G1 X0 Y6 F1200`
G1 X536
G1 X6 F600

To the start code. This moved the machine to its true home at 6,6 which had the ball at the lower left corner. I’ve since fixed the end stop locations so that it doesn’t move the ball outside of the working area, and don’t need that code any longer.

Yeah, I was looking for something a little more automatic but I can’t find any gcode configs you can do in fluidNC.
If I send the command G94 F1000 in the web gui it will run the sandify gcode file but I have to do that after every restart

I add G1 F1000 in sandify in the starting gcode.

I haven’t seen anything to do that automatically or in the fluidnc config.

Great thanks, I’m playing with marlin now because it looks like it can read auto0.g from the sd card on boot, I am going to try and put these commands in that.
