Finally Marlin 1.1.4 on my DMS DP5

Thanks !

Yes! stock main board !  stock fans,  the firmware 1.1.4 shared in my googledrive  has AUTO_BED_LEVELING_BILINEAR in all the bed and safe homming activated. 

another great function activated is leveling fade height!

Extract from marlin web site
Leveling Fade Height

#define ENABLE_LEVELING_FADE_HEIGHT

Available with MESH_BED_LEVELING, AUTO_BED_LEVELING_BILINEAR, and AUTO_BED_LEVELING_UBL.



This option adds the Z parameter to M420 which sets a fade distance over which leveling will be gradually reduced. Above the given Z height, leveling compensation will no longer be applied.



This feature exists to prevent irregularities in the bed from propagating through the model’s entire height. Fading out leveling also reduces computational requirements and resonance from the Z axis above the fade height. For a well-aligned machine, this feature can improve print results.



Example: To have leveling fade out over the first 10mm of layer printing use M420 Z10. If each layer is 0.2mm high, leveling compensation will be reduced by 1/50th (2%) after each layer. Above 10mm the machine will move without compensation.

i make a test with fade height in my start gcode at 1mm  and the Z steppers stop moving just past that height setting, solid like a rock:

G21 ; set units to millimeters

G90 ; use absolute positioning

M82 ; absolute extrusion mode

M140 S{material_bed_temperature} ; set bed temp

M104 S{material_print_temperature} ; set extruder temp

M190 S{material_bed_temperature} ; wait for bed temp

M109 S{material_print_temperature} ; wait for extruder temp

M420 Z1 ; Z fade height at 1 mm,  for best results  5mm or more.

I have a DP4 & did the 1.1.4 upgrade as above for the mesh leveling option, but now I am having constant "heating failed" errors requiring hard resets.

I tried modifying
#define WATCH_TEMP_PERIOD 60 // Seconds
#define WATCH_TEMP_INCREASE 5 // Degrees Celsius

to the current settings with on luck.

Any thoughts - short of replacing the thermister out entirely from the hotend? Had no temperature issues on the original firmware that came with it. Have also tried a current 1.1.4 from Github & get nothing at all except 2 lines on the LCD.

Thanks

Hello Jon !  Welcome to the Forum!, sorry for the late response,  i have the very same problem  at the beginning of using this firmware 1.1.4,I definitely thought something was not right, because I've never had this error before with the factory firmware, although I admit I had less of the month with the printer and almost no experience with 3d printers.
And I discovered that part of the error was caused by myself being in the "tune" menu by adjusting the temperature constantly during the printing or during the autolevel phase, reading in the marlin forums it seems that there is a setting parameter where If a loss of more than 10 degrees Celsius is detected for a certain time, the printer considers it to be a failure of heating and for safety halts the printer.

In this marlin 1.1.4 during the final stages of a 5x5 bilinear autolevel the temperature of the hotend falls between 8 and 9 degrees celcius, I suppose for the over voltage requirement in the motors, but recovers when starting the process of printing avoiding the Heating error, having the printer at room temperature in a room without air conditioning (I live in Sonora, Mexico where the outside temperature is 45 degrees in the shade with 55 degrees feel) helped a lot to the temperature loss in the hotend.

I recommend starting at a conservative temperature in PLA would be 190 C and I with ABS from HATCHBOX in 215 C extrude perfectly. 

Please tell us how it turned out

Hello!
I have some questions about this firmware.
1. What I need edit to change language on LCD?
2. Should I have to change something in files before uploading firmware?

Thanks! I will try to do this on this week.
