Nextion serial garbage

[vandykl]

If I touch the splash screen after startup I get the following on the serial communication of Simplify3D and similarly Pronterface:

And when I try to move axis with touch: (pronterface)

[jgauchia]

More tests... When firmware starts and touch nextion screen the temperature of extruder/s increase quickly and the printer doesn't works (hanged). If the screen was in splash screen the printer works without problems.

[MagoKimbra]

I tried, but in no case I get problems like yours. I just can not understand why you have those problems .. Send me your configuration...

Hi, When extruders are heated up, and printer works correctly when nextion is at splash screen , if you touch the screen later, then works perfectly.

[Deepoff]

Here's incorrect conclusion the current coordinates on the screen. Disable this code - garbage will disappear

[jgauchia]

Where is located this code? Nextion_LCD.cpp ?

[Deepoff]

yea

[jgauchia]

Thanks I'll try it

[jgauchia]

Thanks Deepoff It's works!

Now I'm trying to find why GCODES sent from Nextion doesn't works.

Display something like this. Echo: enqueueing "G91" Attempted to write invalid text to console, which could be due to an invalid baudrate Echo: enqueueing "G90" Attempted to write invalid text to console, which could be due to an invalid baudrate [ERROR] Traceback (most recent call last): File "/home/jordi/Printrun/printrun/printcore.py", line 118, in logError try: self.errorcb(error) File "/home/jordi/Printrun/printrun/pronsole.py", line 257, in logError msg = u"".join(unicode(i) for i in msg) File "/home/jordi/Printrun/printrun/pronsole.py", line 257, in msg = u"".join(unicode(i) for i in msg) File "/usr/lib/python2.7/encodings/utf_8.py", line 16, in decode return codecs.utf_8_decode(input, errors, True) UnicodeDecodeError: 'utf8' codec can't decode byte 0x8f in position 25: invalid start byte

[Deepoff]

Open new issue for this problem, please.

[jgauchia]

Ok, I've already open an issue (#84) with something similar but with a previous version of MarlinKimbra,
Also, I'll try Repetier Host,

[Deepoff]

to send commands in text form you need to use another command . But while this is only my assumption .

[jgauchia]

Commands are sent touching the different move arrows in Nextion menu

[Deepoff]

strcat(buffer, TEST(axis_known_position, Y_AXIS) || !TEST(axis_was_homed, Y_AXIS) ? PSTR(" Y") : PSTR(" ?"));

strcat(buffer, TEST(axis_known_position, Z_AXIS) || !TEST(axis_was_homed, Z_AXIS) ? PSTR(" Z") : PSTR(" ?"));

Here it is necessary to remove code "PSTR" to normal work code watching coordinates.

[jgauchia]

Ok thank you!

[carmelf]

Hello , i think i have the same problem after connecting the nextion 4.3 to my mini kossel the move axis dosent work and i have the same error on my Arduino terminal : " Echo:enqueueing "G91" Echo:enqueueing "ep..." Echo:enqueueing "G90" Error:Unknown command: "ep..." "

also i notice that my motor drivers on the ramps 1.4 get extremely hot. where should i put this code ? " strcat(buffer, TEST(axis_known_position, Y_AXIS) || !TEST(axis_was_homed, Y_AXIS) ? PSTR(" Y") : PSTR(" ?"));

strcat(buffer, TEST(axis_known_position, Z_AXIS) || !TEST(axis_was_homed, Z_AXIS) ? PSTR(" Z") : PSTR(" ?"));"

maybe this is my problem ?

[jgauchia]

If motor drivers are extremely hot , try to adjust voltage level of the stepper drivers (pololus) I think that this "piece" of code it's correct in last version of firmware, it's inside Nextion_LCD.cpp

This isn't the problem , i think, I didn't solve it...
