Geeetech

Hi folks,

Please look my first non test prints for big objects :)
This is spear parts for I3B.
As you can see, this object have some "waves" on Z axe. The "wave" repeate every same numbers ov leveles. I print on speed 20 ms, infill 70%.
a bit ugly objects with those "waves".

Hi folks,
If some body use this mount with MK8 on I3B?

Do need some modifications in the firmware, for auto bed leveling work?

When testing at the 2 ends of hotbed wires, the resistance is 1.2 ohm, so the current is about 10A.
The resistance of extruder is around 4.2 ohm, so the current is 3 A, it is enough for heating the nozzle.
We use 12V output voltage, so higher voltage may burn the board.

In this case, the 15A ...

The hot bed resistance is 0.9 Ohm.
The current drain for the hot bed is about ~13A.
The power supply is 15A.
I did not measured the resistance for extruder heater. But i think what 3A is not enougth for extruder, all of motors and rest of electronics.

The board was attached to the frame with capacitor and MOSFETS directed to the fan.

The cable swaping did not help.
The problem was, wrong LCD type selection while upload firmware.
The problem solved by reloading firmware and defing #define REPRAP_DISCOUNT_SMART_CONTROLLER

.7 ohms
The hot bed seems not so good. 0.7ohm will almost double the current, and the MOSFET will be burnt.
You should contact the customer service. Tell them your problem.

I have a same simptoms with smoke. Tested the resistance of the bed and get 1.0 ohm. Is this ok? This is a new Geeetech ...

Hi,

After first power on, just assembled geeetech prusa i3 printer, on the LCD I see strange characters. Look at the pictures attached. Double checked all solder pins on LCD PCB and on cable adapter, no problems found.
Can some body to advice?
