So, after make a small code to write pin (trial and error), i found the 3 pin for the heater, fan and the bed. that pin have led, so i can found the pin number based on the led.

After matching the pin number with the pins.h in repetier firmware, i found that this board was using RUMBA schematic, motherboard=80 in repetier.

Case closed.

I don't think it's really a Rumba, because it only has 4 stepper drivers.

ya it looks like something that was a one off for a basic printer where they built like 2000 of them and that was it....

it will run marlin etc but your going to have to work thru the settings to get everything right and do so with nothing but trial and error to go on.

I would not bother with all the time to do that when better controllers are around that can be put in your hands for like $30

yea, sorry , but its already work with motherboard = 80 in repetier. (on pins.h its says rumba)
Its already work normally.

This PCB was at discount and its cheap about $15. has no brand on the PCB at all and the link to buy is off, thats why its difficult at first.

Thx

I am glad you got it going then smiling smiley

If you find it dies on you give this a go.

I have a few of them, Ramps 1.4 compatible, lots of room for expansion, good components and can be used at 24v too.

For the price its hard to beat.

That said I chose not to use it on my next build as I invested in 32bit duet wifi.
