stepper direction wont reverse.
-
Just having an issue reversing my z axis. changing the values in config.g from s0 to s1 doesn't have any effect. I ended up reversing my motor direction manually but im worried the value will eventually work, since i had a similar issue with my network setting where the values wouldn't take then eventually randomly did. The only difference is my z axis will crash into my tool head if it does randomly work lol. i checked the override and there are no values that pertain to motor direction.
-
@davidvh86 I'm guessing you've checked this, but you don't have anything resetting it in your homing files do you? Not that I er... ever er... did that...
-
I dont believe so most of the values are strait out of the rep rap configurator, the biggest change i made was mirroring the y axis on the e2 driver, since i have two y stepper motors driving the y axis.
-
Please share more informatin. What board? What firmware version? Share the results of M122. Also share your config.g and homing files.

Sure its a duet wifi running the latest stable firmware

What type of printer is this? Where are the endstops located? Are you intending to use the z probe to home z or the endstop? Right now it's configured to home to Z max, as in the farthest point from the nozzle, is that correct? It can be tempting to change the Z direction sometimes when the real issue is misconfigured endstop positon.

Yes i home to max to get a rough start point then i just add some start code to my prints to use the z probe to get an accurate z0 when the print starts. Idk im used to delta printer and want everything to basically go away from the tool head when i home. Oh and probably the should have mentioned that the printer is working at this point, just was worried about not being able to change directions without manually re pinning the connector. just wanted to sort everything before i get it all back together.

Yes that is a little bit weird. Things to check is that you are editing config.g and not config.g.bak or config.json. Also make sure you're editing the files in the /sys folder and not somewhere else. Also the board must be reset after saving the changes for them to take effect. Also ensure you've identified the right driver and M569 command.

I have the same problem with my extruder on my 1LC board. Updated both the board and the Pi (which somehow made my Pi4 not boot, as it has been for weeks, using the 5V-->SBC but does with USB power weirdly) with no change. My GCode included below.

@Phaedrux
Yea I kinda just re-pinned and continued with the build. I was defiantly editing the config.g . Just worried the settings are gonna take one day like they did with my wifi setting ( went from dynamic to static) and destroy my printer lol. -
@davidvh86 I just had to do the same. I thought I was being stupid for a good bit before I worked out it wasn't me.
