Hi Phizinza!
Yes I do;
There are some points you have to consider to get it running :
- Use the GEN7 Arduino files which come with Marlin (otherwise you'll get compile errors)
- Till Gen7 v1.4.1 there is a hardware issue (wrong coil was used) which might lead to brown-outs. You could either change L1 from 100uH to an 10uH coil , or try to set your brown out detection from 4,3V to 2,7V. Both solutions worked in my case. (Gen7 v1.4.1)
In my case I haven't noticed any other limitations with marlin.

Looking in the Marlin firmware config file I'm having trouble figuring out what I need to set and change...
First issue is the define temp sensors section.
I am to assume temp sensor 0 is the hot end on my gen7 board?
The thermistor I used on my heat bed is not in the list. Do I just have to add the table to the thermistortables.h as another number and then choose that number in configuration.h for the temp_sensor_bed?
Next endstops...
I only use the min endstops on my gen7, do I comment out the define endstoppullup max options?
Why is the min endstop for Z axis already commented out?
Thanks!

I've got marlin compiled and uploaded to the 1.3.1 board, with the 10uH inductor. I have a problem with the thermistors, they read quite low (-23c) when I issue the M80 to start the PSU (still haven't done the insulated thermistor standby by power mod so I have to start the PSU before Marlin lets me do anything due to the safety cuts with temps. But the only thing I can get marlin to do is move the Y and X axes 6 to 7mm at a time and it only does that when I press the home button in Pronterface..? No other buttons work or do anything. And the movement is only away from the end stops...?
Any idea where I have gone wrong?

Are your endstops working properly? In standard configuration Marlin insists on them and reports their status with M119.

Since the topics here, i have a question regarding marlin.
I have managed to upload firmware (Arduino 1.0) after coil change, and everything seems to work except thermistors (temperature is 0), heaters and extruder motor.
My specs:
-Gen7 1.41 with ATmega 1284p 20MHz
-Optical endstops
Thank you in advance.

Didnt report no such thing. Well i am worried because it hasnt done it before, not in teacup and not after couple of seconds. Configured pins according to this (https://github.com/ErikZalm/Marlin/blob/1a18a487f972880ef64e7787f99d6276f16291a9/Marlin/pins.h)
Thought it would work right away.
Think its burned out, unusable? Right now not sure how i would get thermistors working..but that is my goal.

Just now i have noticed that HPB heater led lights up and IRLB8743 is smoking !
You managed to get this fat MOSFET smoking? That means you hooked up a bed before checking wether the MOSFET is working.
I'd guess your pinout is wrong. The MOSFET I/O pin isn't served at all by the ATmega, accordingly the voltage on this pin is floating. You should ensure the LED lights up in accordance to the heater commands given (M140 S80 vs. M140 S0). If that works, hook up the bed.

As last resort i downloaded fresh copy of marlin v1 from github.
Didnt mess with pins.h, uploaded and now extruder heater and thermistor is working, but no such luck with heatbed (still zero, no matter which thermistor i chose from the list).
Still wondering what went wrong with previous upload?
Did everything per instruction except, when i now cross reference config.h, swapped 0 and 1 pin in temps....

Can you measure the voltage on R11/R12? Doesn't matter which side of it. It should be 0V with heater off, 5V with heater on. If that happens, but the LED still doesn't light, the MOSFET needs replacement.
You could also use SetupTest.ino to check the MOSFETs. Very simple to configure, see the first lines of its source code.

As soon as i connect in repetier host bed heater LED is on.
Doesn´t matter if the heater is on/off, it just always stays lit.

It is what? 0V or 5V or does it change depending on the G-code sent? In case it's always 5V it might be a burned ATmega pin. You can try to use one of the remaining pins. Requires cutting the regular track on the PCB, the re-soldering it to the new pin.

Heater off 0V
Heater on 5V
Then your MOSFET is damaged and needs replacement. Next time you experiment with firmware, please disconnect the load (heated bed) until you see the LEDs working as expected.
... and I guess Gen7 v1.6 gets a pull-down resistor for those few minutes in its life it runs without proper firmware.

Does the firmware its self still work, can you still communicate with it, does M114 report position changes?

Yes it does, i can connect in repetier and pronterface.
Extruder heater and its thermistor work, heatbed thermistor still shows zero temp but heater LED light goes on and off at command (after MOSFET replacement).
M114 reports position changes on all axis except it doesnt report homing movement on X.
Strange enough, motors were working fine until i replaced burnt out MOSFET.
Now they dont work at all. Not in Marlin and not in Teacup also.
