    So from Control > Temperature you can't raise it past 240? That to me indicates firmware or software is limiting it to 240

    Yes, but if I print parts from SD card I can raise it above 240c (setup from S3D and save as toolpath).

    That's weird then. Mine stops me before going over the max setpoint. I'd double check your firmware

    Changed :
    #define HEATER_0_MAXTEMP 255
    #define HEATER_1_MAXTEMP 275
    #define HEATER_2_MAXTEMP 275
    #define BED_MAXTEMP 85

    Should I also change #define ABS_PREHEAT_HOTEND_TEMP 240? ie: change 240 into 255.

    Whatever you use for ABS should be your preheat setting. How were you telling it to go to 240 befroe?

    I can telling it from S3D when making a toolpath. But what I do to use the LCD, I only uncommented Reprap Graphic LCD and added u8glib.

    Found out that the LCD temp control has difference 15c lower from the maxtemp from firmware. In firmware I set for 260c and in LCD max temp is 245c.

    Will this work with the XXL LCD Controller? I can adjust the Z Axis in during the print on the XXL but it does not appear to do anything. What are the firmware changes you made in Marlin?

    Thanks
    Rick

    Rick,
    Babystepping works great with the XXL LCD. You need to modify the firmware as shown in Ziggy's document (attached)."Marlin BabyStepping.pdf"

    After making these changes and downloading to the Arduino a new sub menu will appear in the Tune menu called BabyStepping. Note the Tune menu will only appear after you start a print. This lets you rotate the Z screws by rotating the XXL LCD knob even though the Z stepper is locked.

    I usually don't need to do this but it is very nice for fine tuning the first layer height.

    Finished mounting my full graphic LCD yesterday. I'll upload more pics and details to my printer's thread later, including the tilt bracket. This was well worth the $20 eBay investment.

    So I just got this screen installed. Is there a walk-through or anything that tells you what everything on the screen means and what you can do etc?

    I never found a guide. I just poked around and most of the menus are pretty clear. At first I did not realized that if you turn the knob while printing and on the main info screen it will speed up or slow down the printing speed. You can tweak it up or down from 100%.

    Ok I wasn't sure what FR was referring to. Fan rate, flow rate etc. Like you said the rest is self explanatory

    My guess is that FR means Feed Rate.

    Are you referring to the Smart LCD Controller XXL? I started working on this in the forum's resources section, but I forgot to finish it up. I'll have to do that soon. There are several things I don't know though. I plan on figuring those out.
