Marlin firmware upgrade advice needed

Hi all
i have a Ebay CTC prusa i3 pro b clone(ply wood one) printers it has the mega 2560 board and chip white pcb on it,
i want to upgrade to the latest marlin as i want to try out the auto bed leveling and have got the bigger full graphic Smart Controller LCD12864.
problem is i have done a bit of reading up and some say you need to put a bootloader on first with a uno board(which i have).But others saying you dont need to do the bootloader now!
so im getting a little confused on wots best. im new to this and never messed with marlin or bootloaders.also does everything have to be unplugged from the pcb before upgrading.also some say done turn it on using the power supply just upgrade the software using the power from the usb.
just looking for some pointers on wots best from you the experts,
if i get the marlin on,would i have to save all my setting first i have now,or does it just upgrade to the new marlin but keep all my settings i have.
i know i have to change a few bits to get the screen working and also change my steps as ive change the leed screws,for better ones and the belts,
i have to do this every time i use rephost in the eeprom setting as the printer doesnt save them to the eeprom it reverts back to the defaults everytime i switch it off/on the printer.
Any help appreciated
Thanks

All setting must be manually transferred from the old configuration.h to the new. (and you cant just copy the file, the format has changed)

If you don't have the original configuration.h most can be retrieved with a M503 command (print settings)
but not all.. and the remaining one are important (type of thermistor, direction of movement, and endstop setting)
If you dont know your thermistor type... your out of luck. Working it out requires setting it known temperatures and taking reading over entire tempature range, (PITA)
The rest can be worked out easily

no way to know if it has a boot loader or not, till you try and put new firmware on it... If it errors with stk500 error, its probably no bootloader.

5v usb power only is best when uploading firmware, mainly as any heaters could be set to on while uploading the firmware, without 12v, it doesn't matter if they are on or not.

Hi Dust
thanks for the reply
i think all the settings show up in rephost, it says marlin sprinter v1 in the log box below.
i also thought there was example files in marlin for all the printers you just pick your machine and load it into marlin then open the arduino ide program and most off the setting are in there or am i wrong in thinking that!!

this is wot it show in rephost in the log box

is everything on there i need to know i can also export the eeprom aswell which i have saved in case

only the tiny bit in the middle from

Are stetting, from a m503 command.

No thermistor settings, no direction of movement, or anything about endstops

The bit "for gen6" worries me
Are you sure you have a 2560 chip? and not a 1284p ?? as gen6 would imply the latter.
Read the number from the top of the large black chip. It will say one of those two numbers.


Marlin comes with examples for particular controllers, but not for particular machines. So will compile and upload, but wont work correctly till is updated with machine specifics

yeah deffo 2560 on the chip i have to change the steps Z2560.00 to 400.00 as ive changed the rods
