The 2 big yellow things next to the power input socket are called resettable fuses, the larger one is rated 11amps, the smaller one is 5 amps. these are known to go high resistance and over heat. A common mod for these is to replace with car type f…

D2 and D12 are both non inverted so should work ok with your fans.
-
ramps-fd uses inverted signals for heaters/fans ramps-fd-v2 uses non inverted signals make sure you have the right board selected in configuration.
-
What motherboard did you select in the configuration ? The radds-fd uses a mosfet driver to drive the output mosfet, so needs active low input(inverted)
-
The direction that is reversed printed, you have that axis's motor direction and homing direction reversed.
-
No eeprom on the GT2560 according to the schematic
-
What values have you set for z_probe_z_offset (bed coating thickness) and Z_PROBE_HEIGHT (probe height)
-
Pls disregard my previous staement, Just re-tested G33 and it is working ok. So, its Just the bed height mapping using G30 that has a problem, on my prussa clone with a glass bed it is showing a 4mm dip in the 1st measurment corner
-
This also seems to happen with G33
-
In the slicer settings, or in repetier host slicer tab, there is a option to over ride slicer setting and move the infil density slider, then slice it. After you slice it you can then save the new g-code to your SD card ready for printing
-
Did you re-slice the object after changing the value ?
-
Not sure but you might be getting a conflict by having both hardware and software Z-max endstops enabled.
-
Love the above link
-
When you home Z, is the nozzle 0.09 from the bed or is it +3mm above. maybe you need to adjust/move endstop position.
-
Should be able to click on tools/port menu and select com11(with your melzi board connected to usb) Also afaik the melzi V2 has a atmega1284p processor, so you need to select this in the arduino tools as well.
-
This error is when you try to upload firmware in arduino yes ? Goto windows deice manager and select ports(com and lpt), in there it should show the port number that the arduino is connected too. set this port number in arduino tools menu,
-
you can edit them directly in the eeprom editor in repetier host
-
In the arduino tools menu you probably have the wrong 'port number' selected. Also make sure the processor type matches the processor on your melzi board. The first line is ok, it recognises the melzi as a arduino mega clone
-
I do not currently have end stops installed which could throw off the z movement. so how does the printer know where it is.
-
You would have to remove the fuse to do it that way. remove the +12 volt wire from the connector, then with meter set to dc AMPS range, connect the meter red wire to the 12v wire from power supply and the meter black wire to the +12 i/p of the conn…
-
you would probably be better using M140 S0 instead of the M190 S0,then it does not wait for the bed to cool own
-
You can use the probe as the Z-min switch AND for z probing, no need for a Z-max switch.
-
Ahh ty for clearing that up, on the reprap g code wiki it states that M302 will just report cold extrusion state
-
You will allso need to take note of the last E value and set this at begining of new code with G92 E value.
-
M302 S0 this will allow cold extrusion to test if it is a temp sense problem. Does the extruder get hot enough to melt filament ? Is the extruder motor turning the correct direction ? (sounds silly but i have been fooled by this myself).
-
You should be able to add it to the slicer end g-code
-
If you have a Z-min home switch you will need to move it lower If you use a Z max home switch, you need to alter the Z max length in firmware
-
1st, make sure 'dry run' is not selected in repetier host manual tab.
-
Is this line correct #define Z_PROBE_PIN ORIG_X_MIN_PIN // #define Z_PROBE_PIN ORIG_X_MAX_PIN seems strange that you have Z probe connected to the X min pin when you allso have a X min endstop
-
The only parts of your config i can see that i would change are the homing order , pre raise options, and Z homing locations as below #define HOMING_ORDER HOME_ORDER_XYTZ#define ZHOME_PRE_RAISE 2#define ZHOME_PRE_RAISE_DISTANCE 4 #define ZHOME_HE…
