Hmm, interesting... so the MAXTEMP was set incorrectly in the stock firmware. I use E3D V6, so have different temperature settings anyway, but good to know... Will try to play with the other settings...

I’ve been reading this topic with interest. I just got me a DP5. I succeeded in making a first print. I want to set the language in English (at this moment it’s Spanish or Italian I do not know). Do I have to do a complete upgrade as described here? I also do not know what the current firmware version is that is on the printer. Is there a way to find out what the current version of my printer is?

Is there a way to find out what the current version of my printer is? M115 will give you the current version info you need plus more, Google something like "find Marlin firmware version". You do need to change the language in the configuration.h file and upload the new firmware, If you're going to do that you might as well download and upgrade to 1 of the versions listed on this thread though, lots of issues sorted.

1.1.4 Marlin from forum seems to work fine for me - Thanks!
I have had Marlin 1.1.1 running for some months now, which was working OK-ish. Had intermittent problems with 'thermal run away', so did not post (also IDN WTF IAD). The problem turned out to be a loose (burnt) thermal sensor wire.
Differences in Marlin 1.1.4 from forum to my existing 1.1.1 config: DEFAULT_AXIS_STEPS_PER_UNIT { 80.5, 80.5, 389.269957, 94.4962144 } Remember reading somewhere on this forum that these are the true numbers for the steppers?
DEFAULT_MAX_ACCELERATION { 8000, 8000, 100, 10000 } Ditto?
Also had to turn on FIX_MOUNTED_PROBE to build?
Other useful goodies I had turned on for 1.1.1: PREHEAT_1_FAN_SPEED 255 PREHEAT_2_FAN_SPEED 255
NOZZLE_PARK_FEATURE
SPI_HALF_SPEED SD_CHECK_AND_RETRY
REVERSE_MENU_DIRECTION
INDIVIDUAL_AXIS_HOMING_MENU
What my Cura 2.6.1 start GCode looks like (poor mans initial wipe): ;NOTE: This will GOUGE HOLES in the bed if Z_PROBE_OFFSET has not been set correctly... G21 ; set units to millimeters G90 ; use absolute positioning M82 ; absolute extrusion mode
M117 Heating... M104 S{material_print_temperature} ; set extruder temp M140 S{material_bed_temperature} ; set bed temp M190 S{material_bed_temperature} ; wait for bed temp M109 S{material_print_temperature} ; wait for extruder temp
M117 Leveling G28 X0 Y0 ;move X/Y to min endstops G28 Z0 ;move Z to min endstops G29 ; auto bilinear bed level
M117 Wipe hotend G1 Z20 G92 E0.0 ; reset extruder distance position G1 X10.0 Y10.0 F2000.0 ; go outside print area G1 Z0.15 ; lower Z G1 X150.0 E10 F1000.0 ; intro line
G1 Y15 F1000.0 G1 X10 F1000.0
G92 E0.0 ; reset extruder distance position G1 Z10; raise Z
M117 Printing...

As an observation, the extruder fan you referenced at: Other useful goodies I had turned on for 1.1.1: PREHEAT_1_FAN_SPEED 255 PREHEAT_2_FAN_SPEED 255, is not controllable from firmware. It is connected directly to the power supply and so runs at 100% no matter what. As for the part cooling fan I have that turned off for the first two layers in my slicer. I don't use auto leveling, but I do a skirt 5mm from part with 5 loops which serves to wipe the nozzle and also to get a good flow of material before moving to print the part.
DEFAULT_AXIS_STEPS_PER_UNIT { 80.5, 80.5, 389.269957, 94.4962144 } some would argue that the values are actually 80.00, 80.00, 400.00 and I found the 94.4962144 was under extruding, by over 50%, because the default filament diameter is set as 3.00mm and the DP5 will only print 1.75mm. Calibration of the extruder is a must, also calibrating when you change filament is good practice too.

Hi, I have many issues with the autolevel function, can you please help me to know how I can cancel from the firmware I prefer level manual

If you remove g29 from your start g code in your slicer, you will not use auto level. No real reason to remove it from the firmware that I am aware of.

DEFAULT_AXIS_STEPS_PER_UNIT { 80.5, 80.5, 389.269957, 94.4962144 } some would argue Thanks again tanephar - that may explain some of my intermittent retraction problems with some prints... PREHEAT_1_FAN_SPEED 255 PREHEAT_2_FAN_SPEED 255, is not controllable from firmware. I have a custom print head and may have wired something backward (cooler vs blower). This seems to be controlling blower (not cooling) in the menu preheat PLA/ABS settings. But definitely point taken - if you crank this to 100% with a 'decent' blower you can quite literally blow the filament off the bed...

psychogony 1 retraction has a lot to do with speed, for PLA I run a 4mm retraction, at 40mm/sec, for PETG it is 4mm retraction at 30mm/sec it has a lot to do with the filament you are using. A little experimenting will give you sweet spots for each filament. I have tweaked the retract acceleration in firmware back to 3000. Like everything to do with 3d prints there are a lot of variables and my set up might not necessarily work for anyone else. Another interesting poin, I live in New Zealand we are entering a hot summer phase now, and the ambient temperature of the room is about 12°C higher than when I first got the printer, the PID values are significantly different, and the temperature stability can have a lot of impact on retraction and stringing. Thank goodness "Winter Is Coming"
