I agree on the rod problem. Normally the printer is delivered with threaded rod of low quality. Many people, my self included have updated these rods to t8 lead screws from ebay. This means that steps per mm changes quite significantly from 2560 to around 400.

Dear William,

Correct. LED Strip is 5v, but needs a signal in order to turn on. Needed 3 pins.

VVC
GND
DIN

Power, is no problem, but I need 1 pin for signal.

In the new marlin firmware you can define a pin number to use for exactly this digital signal, in order to have SMART LED control.

As I ...

To clear up, I like the "smart lightning" functions.

// Support for Adafruit Neopixel LED driver
//#define NEOPIXEL_RGBW_LED
#if ENABLED(NEOPIXEL_RGBW_LED)
#define NEOPIXEL_PIN 4 // D4 (EXP2-5 on Printrboard)
#define NEOPIXEL_PIXELS 3
//#define NEOPIXEL_STARTUP_TEST // Cycle through colors at ...

Hi William,

Thanks for your reply. - I was wondering if I could use eg. pin 24 X-Max or 28 Y-Max and define this in Marlin as the pin for LED control, as these are not used in my setup.

I do not know if the pin numbers are the same on the GT2560 Rev A+.

I use GT2560 Rev A+, on a I3 Pro B.
To which pin can I attached a LED Strip?

Hi,

How did you add the "change filament" and statistics of the printer (how long time/Much filament used etc) to the Marlin FW? Is this a custom fork? - Reason I am asking is that I cannot find anywhere references to this in the Marlin FW.

Yesterday I performed my first longer print with this firmware. For some reason my printer froze 2 hours in.
I have never tried this before. Any suggestions?

I have installed this and it works perfectly. Thanks so much!

Thanks so much for a fantastic firmware. Great with new features etc, compared to official old Marlin firmware. :-)

I have few minor issues, and so far I have not been able to track down if this issue originates in the printers firmware or in my slicer.
