Congrats to RTCNC, that’s a fast turn around patching issues from 1.4.6! ---

Yes, this one was done in record time! ---

I just got my Redline controller. I’m not sure which version came with it. After startup, I unchecked the reverse axis direction for the X axis, and it worked fine (I have my X Axis motor mounted on the left side of the machine). I then upgraded the firmware to 1.4.9, but now that option doesn’t work as shown in this [video](https://photos.app.goo.gl/47LLbChzD6zv91yC9). I tried rebooting the machine after unmarking that, but that didn’t work either. On top of that, the option goes back to be checked. ---

Hi Neel, Your x rail is set up incorrectly. The motor should be on the right side of the machine. ---

Yes, I understand the preferred way is to have the X axis motor on the right side. Given my setup, it makes it much easier to have the motor on the left side. Before the current update, this was fine after I unchecked the “Reverse axis” for the X axis. But with the current update, that option does not work anymore. ---

The next firmware should fix this (releasing soon) ---
