My problem is communication. Printer makes 2 (Lines) commands and stops. I've tried all possible configurations and always the same. Does somebody has any idea?

sorry can you give more details of your issue ? what do you do ? and what happen ?

It is not clear

[jojoxyz]

Whenever I execute G28, everything goes ok, but then no command works anymore. Or if I drive manual it works with 1 or 2 movements and then no longer reacts. When I start printing, the printer starts to heat but does not start to press. Once I reached the cold print - printer makes a command, (Line) then waits about 10 seconds and starts again with a command, (Line).

Ok weird - more questions.

• What is your Printer FW ?
• What is your ESP8266 board ?
• Wow did you wired esp to ramps ?

when you start print ESP3D does not do anything after so if printer heat but do not actually anything the problem is on printer side (FW or Slicer) Fromt another point of view when heating most of printer FW reject any commands until temperature is reached

• Please copy and past the [ESP420]plain output from terminal command

  • when commands stop working : 1 - does [ESP420]plain command still give out put ? 2 - what is the terminal output when sending M115 ? 3 - does your printer still works from your printer menu ?

3- yes

[luc-github]

what change did you do in repetier to make comunication working between mega and esp?

does this happen using telnet client like putty and 8888 port ?

[jojoxyz]

but nothing works. I made small progress with memory change and time setting in repetier host actually everything is configured correctly but it just doesn't work.

[luc-github]

actually everything is configured correctly .

then it should work

but it just doesn't work

So it is not configured correctly

I made small progress with memory change and time setting in repetier host

so you do not use webUI ? only repetier host and tcp 8888 port ?

also what change did you do in repetier to make comunication working between mega and esp? which serial port are you using for ESP ?

[jojoxyz]

I tried standard 8888 and others but nothing. In mega bluetooth serial 3 web ui makes the same problems.

[luc-github]

what is baudrate on bt seriat 3

[jojoxyz]

115200 I also tried 250000 no effect

[luc-github]

by default in FW it is 115200 so esp need to be also 115200 - I guess you be sure both match ?

it may be a bug of repetier V0.92 - now repetier is 1.0.4 final did you tried it ?

[jojoxyz]

both values are the same. i am trying fw repetier 1.0.4 but with the same result

[luc-github]

well I have not clue what going on - I do not know this board

Is the usb disconnected ? I see depending of switch the USB is also sused by ESP

[jojoxyz]

the problem is: if i separate ramps from mega it works. shows temperatour, loads fw config.

[luc-github]

so it is micro switch configuration problem ?

[jojoxyz]

ON | ON | ON | ON | OFF | OFF | OFF

all functions are ON

[jojoxyz]

problem is internal configuration in fw (pins), but no idea how icg can solve the problem

[luc-github]

what about on on off off off off off off?

[jojoxyz]

no other configuration does not work. mega must have access to pins and wifi at the same time. that only works in my configuration. I tried it with blink led / server

[jojoxyz]

problem solved. tx3 pin 13, 14 connected at ramps on y min, y max.

I have defined the pins in fw as not used and ynim, ymax have defined other pins.

[luc-github]

great ! happy you found out
