Selector Knob

[BTP]

For some completely random reason my MaxV2 wouldn't home. I would select home on the LCD and it would drop about 2" and reset my Z0. I tried both sending it a G28 and clicking the home all button in MatterControl, same result. So I decided to wipe the RAMBo clean and re-load the firmware. After doing so everything homed correctly, but now my selector knob on the LCD is opposite than it was before. Before, you would rotate it CCW to go thru the menu, now it's CW. Same for setting the Z height. Is this a setting I can change in the firmware somewhere? Any help is appreciated.

Thanks, Scott

The shaft encoder direction setting is what you'll need to change.
Presumably when you wiped your firmware, you also wiped all the stored configuration settings.

15Dec15 – Note that if your Rostock MAX v2 kit came with an LCD panel that has a red
PCB, you'll need to make a few changes in Configuration.h to accommodate the requirements of the
different LCD.
Open Configuration.h and scroll down to around line 1157. You should see two lines of code
that look like this:
#define ENCODER_DIRECTION 0
#define UI_ENCODER_SPEED 1
If your LCD PCB is white, then values for those two elements should be 0 for
ENCODER_DIRECTION and 1 for UI_ENCODER_SPEED.
If your LCD PCB is red, then the values for those two elements should be 1 for
ENCODER_DIRECTION and 2 for UI_ENCODER_SPEED.
I recommend that you check out the following blog post by SeeMeCNC's John Oly to find out
why these changes were made. http://www.seemecnc.com/blogs/news/8169 ... e-changes1

Excellent! I'll go try that right now.
