Does the latest edge firmware-cnc.bin includes ABC axis support?
Unless there is something specific about the latest build…
You need to compile for 6 axis:
But this was merge , why the compile?
The compile is because smoothieware .bin is compiled for 5 axis. So you need to compile for 6 axis if you want C.
I just want A
Remove/ disable the extruders from your config and try to define an A axis per the docs linked above.
Yeah I just wanted to make sure it’s there. Have a user wanting to test but it did not for him hence the question to confirm
@raykholo hi Ray. I’m the one trying to get rotary A axis working the the mini.
I defined the A axis (delta) per the docs listed above and disabled the extruders. Flashed the latest edge firmware cnc. Made sure the A axis pin assignments are correct in config.txt as follows…
I can get the motor to spin if I plug them into the Z axis so I know the driver/motor/wiring is ok. If I move the driver/motor plug to the A axis. Can’t get it to spin. The stepper motor never gets enabled, motor shaft doesn’t lock.
Before I lug down the Oscilloscope to check the board out, has anyone verified the latest firmware to actually work for A axis.
The firmware works fine for x,y,z movements. No problem running the laser but can’t get A axis to respond.
Derp. Quick way to rule out the board is redefine the Z pins to the A socket (and un-define A in config in the process).
@raykholo why didn’t I think of that. Duh. Ok I reverted to a earlier config.txt without the ABC axis mods. Changed the Z pins to the A socket and got the motor to spin. So physically the board is fine, all 4 stepper sockets are good.
So something is either wrong with my modified config.txt or latest firmware is broken.
Yep, we test for this sort of thing before shipping boards
Going to need some help from the Wolfs on this one, please post a config file.
The config,txt I’m trying to get working for rotary A axis. Works fine XY lasering. Using latest firmware-cnc.bin that is posted about 6 days ago.
I decided to download the source and rebuild for multiaxis. It WORKS!!! Rotary A axis moves when running gcode.
Ok so we do have to recompile. Did you do make AXIS=4 CNC=1 ?
@raykholo make AXIS=4 CNC=1 is what I used. Didn’t need the 5&6th.
Only did a quick A axis gcode test to see the rotary move. More testing is needed to see if any issues.
Yeah that’s what I originally thought needed to be done.
@Jim_Fong that’s awesome! FYI the video freezes around 30 seconds in, but still, the point was made and made well!
@raykholo YouTube messed up video. Re-uploading again.

@Jim_Fong , Could be possible to know which postprocessor, or CAM software, did you use to generate gcode for 4th axis operation ?
@Antonio_Hernandez at the time, I used Laserweb4 to create the gcode.
