I think you are having issue with the MELZI board cause you did not have the right firmware.....
Is your P802M uses threaded rod or lead screw?
Threatened rod most likely is using the step revolution at 1600, but if your kit uses lead screw then it would be 400....
also, remember that the Zonestar's MElzi board, the manufacture is using their own temp table the sensor is under 501 type
also, the LCD with 5 bottoms uses its own coding within the Repetier firmware and MArlin...
so, If you are downloading from the net, certainly it would not work correctly....
I have mine Repetier V0.91 and Marlin V1.0 w/ABL both working

I have mine Repetier V0.91 and Marlin V1.0 w/ABL both working
yes.. i have the lead screw and i manual measure i got to the ~400 i needed, but still good to know the settings are good
and i used 0.92 firmware for the 5 bottoms and everything works fine
also i have the same printer
mine is 220x220x230
from 3d star aliexpress
but mine is p802m transparent , had the Repetier V0.91 and now on 0.92.5
and:
how can i do PID to the bed ?? when printing ABS it take more then 10min to get it to 100c (but when ig get is stay level very good)

@Robkadett
after PID test i use hotend PID
P - 6.65
I - 0.15
D - 72
big change from 0.91 factory firmware, but better result for me
that from the reprap PID page, try it out for fine tune
"For manual adjustments:
if it overshoots a lot and oscillates, either the integral gain needs to be increased or all gains should be reduced
Too much overshoot? Increase D, decrease P.
Response too damped? Increase P.
Ramps up quickly to a value below target temperature (0-160 fast) and then slows down as it approaches target (160-170 slow, 170-180 really slow, etc) temperature? Try increasing the I constant."

What are the kind of upgrades you can do to this printer besides upgrading the printed parts, upgrading the frame, adding a sensor?
Can you upgrade the build area? What would you need to do to be able to do that? Is there a larger build plate you can get with a heated bed part? or if you got a larger build area (alum or glass)
Can you use the smaller heat pad or is there a larger version you would need? Longer rods, plus would you need to just salvage parts and just build a whole new frame, etc? Or would it be best just to buy 100% new parts and build a 2nd printer?

Short answer: Not with the melzi board. There is no additional output for a secondary extruder/stepper. With RAMPS 1.4 it is possible.Quote

Can you turn this into a dual extruder setup? I would imagine it would require something in the firmware of the unit? Maybe not if you print through the USB cable?

AND the heat stay !! from 0 (not really, but around 15c) to 80 in no time... to 120 took less then normally do 100c when printing ABS
at 120c cant touch the bed.. too hot ! but can freely touch the insulation bottom (its warm, but not hot)
the bed is off for ~20-30min now and its only got down to ~50 so i think it safe to say the insulation works! not the best, but works...
thanks for the help so far =]

for what? imho the x/y axis rails are the most robust parts on this printer. Before doing this you should think about building a complete new frame.
dsol: moving the PSU out of the box is a good idea, moving the mainbord out of it also. But you'll need a big multi-connector for all the cables, otherwise the whole thing isn't really hackable anymore. Background: the stepper drivers are under room temperature conditions nearly stressed, but in a closed box with ~50c they'll tend to malefunction without active cooling.
