Need Help with first RepRap configuration (Prusa I3 Rework)

see the marlin with the arduino symbol open that one

still nothing,

i click Sketch>add file > pins.h and it asks if i want to replace the existing Pins.h

but i cannot find it!

yes i have opened Arduino MArlin File but no luck, same storey

got me stumped coffee time,

if it helps i am using,
arduino 1.0.5 -r2

yes, coffee, shower, fetal position

if that list had a toggle option, we could see more files.

i started a new sketch, pressed add file and selected a copy of pins.h...

did it the first time and it was blank, nothing to see,
did it the second time and it said would i like to replace the other pins.h

see,, its invisible

arduino 1.0.5 -r2" whats running here,

just shouldn't have to do that.

i shouldnt have to, but it says it is there but it is not there!!!

the only reference i can find is on the first marlin file

its not you i just downloaded it and opened all i get is the marlin file like you and nothing else

ok step back download it again, in download you see Marlin-marlin " extract that file to desktop once in the desktop open the marlin-marlin > marlin , you should see all the files scrol dwn till you see the marlin next to the Arduino symbol click that " fingers crossed

I downloaded again. from github.
still nothing

i hit it with a hammer,

tried to import pins.h,

it deleted pins.h from directory

redownloaded pins.h and extracted only this to desktop

open pins.h (desktopversion) into arduino IDE

asked if i wanted replace pins.h that was currently there

i said YES!

brings me to pins.h

if i click away, the pins.h file is lost,

but i think i am here, what do i need to edit now??

this??

#if MOTHERBOARD == 88

#define KNOWN_BOARD 1
#define AT90USB 1286  // Disable MarlinSerial etc.

#ifndef __AVR_AT90USB1286__
#error Oops!  Make sure you have 'Teensy++ 2.0' selected from the 'Tools -> Boards' menu.
#endif

it has placed itself back into sketch directory. which is great.
if i edit it now, it will save.

scroll dwn to line 465 "* Arduino Mega pin assignment"

and change it so it looks like

// uncomment one of the following lines for RAMPS v1.3 or v1.0, comment both for v1.2 or 1.1
#define RAMPS_V_1_3

done, what now?

could we make extruder fan come from D9 ????

could we make extruder fan come from D9 " is the print cooling fan by defalt
now we on to the hard stuff back to the config.h file

WTF...

1) ignore jinx. he is leading you completely astray.

You do not need to change anything in pins.h unless you have a non standard board. Ramps is the most standard board out there.
It is in your list of file, the list of file is just really really long. (you may need to look at pins.h later for your LCD, but lets get basic stuff working first!)

2) Go back to start.

leave the LCD disconnected

Get a clean un modified copy of your firmware, load that into your arduino IDE

Open up the configuration.h tab

You only need to configure 4 thing at this stage

line 28 #define BAUDRATE 250000 you basically need to know what this line says to set up the host program the same.

Line 77#define MOTHERBOARD 7 you have type 33 so make this line read #define MOTHERBOARD 33

Line 137#define TEMP_SENSOR_0 -1 this defines what type of temperature sensor you have on the hot end. You have not mentioned what type of thermistor you have, but im presuming is a type 1 as your referenced the replikeo.com site, so im guessing this is where you got your printer. so change this to #define TEMP_SENSOR_0 1

Line 140#define TEMP_SENSOR_BED 0 same as the hot end but for the bed. Change to #define TEMP_SENSOR_BED 1

Save these changes.

Upload this to your board.

Close the arduino IDE

Open up you host program Repetier, connect to your reprap. remember to use the baud rate above.


Does it connect?

If so try sending a simple command to the printer M119 Does the printer give back an answer?

Once we have basic computer to board communications working we will move on.

I suggest you get things working in this order.

Basic communications
Thermistors reading correct room temp
Endstops working as they should, if these are wrong it can stop all movement.
basic movement of X stepper
Verify X moves right when told to move in +ve directions and left when moving in -ve directions.
repeat for Y axis. +ve the bed moves towards you and -ve the bed moves away from you (opposite of what you think it should be, but correct relative to the head)
Check positions of your ends stops, most are at the min locations but some suppliers put them at max.
Set your homing direction appropriately in firmware
Check that you can home X and Y axis
Basic movement of Z, does Z move up when told to move in +ve direction and -ve moves it down.
Set the Z endstop (for now I would set it 10mm above the bed for safety)
test out Z homing.
Once Z homing is working move it so the Z endstop is just above the bed. (presuming its not one of the silly printer with the endstop at the top)

then e steppers..
then heaters..

Then the LCD

Now you have to calibrate your printer

Then you will be printing.

so you sayin we dont need to make the relevant changes to pins.h about which mega in use or which ramps set up to use. is that right Dust

hello guys, error message

ConfigurationStore.cpp: In function 'void Config_ResetDefault()':
ConfigurationStore.cpp:302: error: 'DEFAULT_LCD_CONTRAST' was not declared in this scope

nevermind

well am waiting for DUST to dust off his crystal ball

Never had to change pins.h for my i3 with RAMPS 1.4, just the Configuration.h

Steve

how you getting on

z axis are not running in sync.

motors are working except for extruder

m302 will allow cold extrusion i think

extruder working, y axis working, z axis working, x axis working... went to print 20mm cube and whole machine started to squeeeeeEEEEElLLL
