Marlin code for cnc

Root Controller

Hi all, anyone has a link with a marling configuration for root cnc?

Regards

Hi,

So I no longer have a Root 3 Lite CNC machine now, I sold it to make way for the big Root 4 CNC machine.

It would seem I managed to delete that variant from my Github page. So what I’ve done is take a new Fork of the current marlin configurations and make the changes I think are necessary for the Root 3 Lite CNC.

You can find that here:

You can see my changes for searching the term

“// Root CNC”

In

Configuration.h
Confiurgation_adv.h

I’ve not compiled the code so please take it as a start point.

HI, Thanks. i am not able to find the configurations. Do you create a new branch?

Ah try now!

whoopsy.

Yeap i am able to see now. Something missing is the number of extruders. I chaged that and was able to upload. What software do you use to send gcode to the router, since mach 3 is not working with my cnc.

Last question, what program do you use/recomend to convert your vectors to gcode?

Regards for all your help

Just had some questions on the Marlin code as well. I had the same result that if I set the extruders to 0, I did not get the following error (when it was set to 1):
“TEMP_SENSOR_0 is required if there are any extruders.”

#error “TEMP_SENSOR_0 is required if there are any extruders.”

Other updates I’m wondering about from referencing the BOM was changing the motherboard type from:
BOARD_RAMPS_13_SF
to:
BOARD_RAMPS_14_SF
and am not sure if we need to change the stepper driver option in config.h
from:
//define X_DRIVER_TYPE A4988
//define Y_DRIVER_TYPE A4988
//define Z_DRIVER_TYPE A4988
to:
define X_DRIVER_TYPE DRV8825
define Y_DRIVER_TYPE DRV8825
define Z_DRIVER_TYPE DRV8825

Ah I see - well that Temp sensor will need to be updated then.

I don’t think the BOARD_RAMPS_13_SF or BOARD_RAMPS_14_SF makes any difference to Marlin but would be wise to select the latest.

Additionally, the two different motor types for the A4988 and the DRV8825 are identical I believe - so changing between the two should make no difference. these two drivers use the interface and the step/ control signals are the same. This section is only value added with you use the TMC kind of stepper motor drivers which require SPI or serial.

But I’ll get those updates done.

Updates are done and commit to GitHub
