QuoteI'm using Repetier Firmware 0.92
1st off i would recommend using the dev version of firmware,it has been greatly improved in the levelling section.
try that and see if the problem is sorted.
Allso, G32 S2 will store the levelling matrix into eeprom.

So after homing Z, if you send a g-code
G1 Z5
does the nozzle move up to Z5 ?
Do you have a -Z offset entered in the slicer ?

In your config.h
Quote#define Z_MIN_PROBE_ENDSTOP_INVERTING true // set to true to invert the logic of the probe.
I think you need to change this to false as the bltouch is like a NC endstop and gives a 5mS +pulse when triggered

Are you using the online configuration tool ?
Make sure you select 'delta printer' on the general tab and set the rod lengths etc.
Under the features tab, tick enable z probing and enable servo, this will open up some more options further down the page.
set probe start script M340 P0 S700
set probe end script M340 P0 S1500
P0=servo 0
you may have to change the S value to suit your servo angle

You can test by replacing the thermistor with a resistor of 100k ohms, this should show a ambient temp reading of ~20C

Hey man, have you read your config file? You should walk through it from beginning to end and try to understand.
// The minimal temperature defines the temperature below which the heater will not be enabled It is used
// to check that the wiring to the thermistor is not broken.

You get it? As long as your bed temp reads 0, it won't be powe

you can use repetier host or mattercontrol both are free and will manually control the priter via usb

I think i would be inclined to use repetier dev firmware on this delta or the latest marlin bugfix, as it seems to use a arduino/ramps controller.

sounds like a good idea, i have one of these probes and can confirm that occasionally it will throw up a spurious result.

You need to screw the throat tube further into the extruder body so that the top of the tube is just clear of the toothed drive wheel.
You could allso fit some insulation around the heaer block to help keep the heat in.

levers 101 people, when that inside spring is fully extended, the idler is at its closest position to the geared pulley.
agreed but it looks like there is NO tension on the spring because the tension bolt is just sitting inside the spring atm.

Your 'auto bed levelling' section looks to be set up fine. dont know why it should try to probe off bed,
Maybe you have some incorrect values in the eeprom,try sendig tp print a
M502
M500
to update the eeprom values
I would alter these 2 lines tho so that probe is untriggered during probe moves.

you cannot print from a stl file, you have to use a slicer to convert the stl into g-code that the printer understands.
typical free slicers are
slic3r
Cura
or use a host printing program like
repetier host
mattercontrol
these have integral slicers built in

your spring looks like it is fully extended thus not putting pressure on the lever, i think it is missing a bolt that should be inserted inside the spring so that the existing bolt screws down onto it to adjust the tension.
somthing like in this extruder

strange, this layout of the melzi 2.0 board shows the hot end definitely on pin 14 and if the 2 connections shown by the red line are connected then the bed would be pin 13
Maybe you have a different layout on your board ?

Be carfull not to over tighten the x axis belt, you may cause the smooth rods to bend.
Your T2 belts from different suppliers should not cause any worry, if your x and y printed dimensions are slightly different you can alter the steps/mm to adjust them.

Well the light should only be on when the probe is close to a metal trigger, so definitely seems like it is faulty.

looking at your pins.h and a melzi circuit the pinout looks wrong,
I think you may need to select a sanguinololu 1.1 motherboard in the repetier firmware tool.

to update eeprom with settings from config send
M502 ;reads config
M500 ;saves to eeprom

The 1.96v on Q3 pin 1 (gate) indicates that the fet is not being turned on fully,
In repetier firmware are you using 'bang bang' or PID for the bed control ?
In repetier host, temperature curve tab, does it show the bed being turned on full or pulsing.

Your wiring looks ok so only other thing i can think of atm is the 5v rail, is it holding 5v ok or is it low? (measure on a endstop connector)

do you still get 12v at the power supply when the heatbed in on ?
What resistance does the heatbed measure (when disconnected from the ramps)
by

RAMPS Electronics
Thats because the mosfet switches the gnd circuit of the bed, so if you measure 12v on both bed wires in respect to power supply negative, it shows that the mosfet is not being turned on.
possible cause is incorrect pin assigned in the firmware.

If you use a externall 5 volt supply you must remove D1 on the ramps board, then you can connect the new 5v supply to a unused end stop 5v 0v pins
