SKR3 direction pin Z and Y2 AXIS

[dresco]

I'll get a logic analyser hooked up to my SKR3 board and investigate..

Sorry, another typo, just pushed a fix;

The outputs look correct to me with that applied?

Missing M4, i'm using 4 axis XYZA plus Y2 on M4.

[dresco]

Ok, reconfigured for N_AXIS=4 plus ganged Y, still looks good here?

Hello Dresco,

I have updated the SKR3, now the Z axis is moving in both way, but the Y2 is stuck in one direction. I tried to remove the A axis, so Y2 is now on M3, but same result.
Before A axis direction was working.

This is very strange, I have Ganged axis & Auto square, I'll try without auto square.

Just for reference, these are the symbols I have defined (building latest master with no other updates);

[JoachimF]

I reload the Git, use your symbols, the Y2 dir pin seems to stay in input mode, I get 3.0V with multimeter, on Y dir pin I have 0.0V or 3.3V

Strange, here is my binary - is that any different?

Hello Jon,

My bad! The copper in the direction wire was broken! Thanks for your help, the router is working, now I have to test the dual spindle and the probe.

Good news! Thanks for the update..

[JoachimF]

Here is the router !!

[JoachimF]

Thanks to you, I use now my 8 port logic analyser :-)

Cool, glad it's working for you! I keep wondering about putting a diode laser module on mine as a 2nd spindle, would be interested to hear how you get on..

I'am also interested to add a diode as second spindle, but I'm afraid by dangerous reflexions of this diodes. I have alaready a K40, but limited to 32*22cm. I Have also hot wire as second spindle, with a second carriage A and B. the wire move between XZ and AB. I use it to cut wings in polystyrene. I want to add plasma cutter more than laser diode, because laser is not very powerfull. The picture is a router that I made with students, mine is smaller, it's a root3cnc. Next steps are rotary cutter on A axis, and vertical hotwire. The goal is to cut carbon and glass fiber fabric, and machine surf. Le ven. 9 déc. 2022 à 10:12, Jon Escombe ***@***.***> a écrit :
