have just replaced my revo with a Rapido Plus Hotend 2 UHF, using a ebb 42 toolboard, have got the jumper in place and getting the error. if i disconnect the wire, i get the error but with out the temp reading, if i remove the jumper the - figure is higher (65707422.564) i'm using ratos 2.1 and have selected all the correct settings
Either you did not chose the proper thermistor (probably PT1000) or the proper temperature setting, loose wire or bad thermistor. Mine will do that sometimes when I don't leave enough slack when bundling wires together.
wiring is fine as there is an obvious difference when its connected and not connected. thermoster is cortrect and so is resistor and pin [extruder]
max_extrude_only_distance: 200
nozzle_diameter: 0.4
heater_pin: toolboard_t0:PB13
sensor_type: PT1000
pullup_resistor: 2200
sensor_pin: toolboard_t0:PA3
min_extrude_temp: 170
min_temp: 0
max_temp: 350
pressure_advance: 0.03
Is it really Rapido Plus (i.e. with PT1000), not Rapido "nonPlus" (i.e. with Semitec 104NT-4-R025H42G)?
Nice pictures, what about hotend you really own?
(the one with PT1000 should have blue wires with label "PT1000")
That good enough for you?
perfect 🙂
(you wouldn't be first who got different model than ordered (especially on Amazon or Aliexpress), hence the question)
You don't have by any chance multimeter, do you?
I D
i do
can you measure resistance od PT1000 at the connector which is directly for EBB?
(it should have resistance about 1100ohm at room temperature)
yeah i'll need to find it
and if you measure anything out of range about 1040 - 1160 ohms (still at room temperature, this range is for temperatures between 10 - 40 °C), do the same at the (original) connector directly on blue wires
Just to be sure, in case it isn't obvious: The connector has to be disconnected from EBB for proper measurement (we don't want to measure parallel resistances and/or voltage from EBB)
so i think the thermostate is dead not getting any resistance
