@dc42 so new board, new problems.
I cant seem to get the end stops to now work.
motors are moving fine but the end stops aren't doing their bit.have a 2 wire endstop so ive wired them on both ends of the endstop. (light starts off as red and then when the stops are engaged turns off) . have tried both X1 Y1 and X0 Y0 and the current code also on my endstop in config.g
M574 X2 Y2 S1 ; Set active high endstops
also i have an E3d hot end and am a bit confused about using the pt1000 amps? ive connected them currently straight to the duet but temps are like 2000c.
-
@magdi right i have made stuff do things.
problem now is when i press to 'home y' it homes y a little and also homes x.
so both axis move not just one. But then they also dont move all of the way to homing. hopefully that makes sense. -

do you mean pt100?
did you configure the m305 correctly?
-
@veti yes pt100 i think.
heres what i have atm but in all honesty im not sure what to configure here.M305 P0 T100000 B4138 R4700 ; Set thermistor + ADC parameters for heater 0
M143 H0 S120 ; Set temperature limit for heater 0 to 120C
M305 P1 T100000 B4138 R4700 ; Set thermistor + ADC parameters for heater 1
M143 H1 S280 ; Set temperature limit for heater 1 to 280C
M305 P2 T100000 B4138 R4700 ; Set thermistor + ADC parameters for heater 2
M143 H2 S280 ; Set temperature limit for heater 2 to 280C -
none of those are for pt100 or pt1000 thermistors
check the configurator for the sensor channel to set it correctly

@veti cheers for the help, i have changed to the pt100, but still have the same issue. where should i then pin the two wires into the board,
-
to the external RTD interface board

@veti i have tried it and still cant connect the bloody thing. so ive found the daugherboard connection point on the duet. that has 10 pins. i only have 4 wires (dual extruders' with two sets of black and red wires connected together) I just dont know where to put the bloody things. the images on the page you supplied are not very helpful and i cant crack the schematic. i think im just being stupid.
-
@magdi Do you have a PT100 daughterboard?
-
@phaedrux i have a pt100 board but it came with my e3d v6 not the same as the duet one.
-
@magdi So you got this? https://e3d-online.com/pt100-amplifier-board
-
@phaedrux yep two of those badboys,
-
Alright, sorry to say, but I don't think that will work. You'll need the daughterboard.

@phaedrux right is there not way just just bypass the pt100 and just connect the thermistor to the duet board?
-
Well if the sensor is a PT100 sensor, then no, it needs the daughterboard to interface with the duet. If you have a seperate regular thermistor, then yes, it could be connected to the thermistor input.
-
@phaedrux i have a separate thermistor sorry i should of said that, the thermistor fist into the pt100 but i dont understand why i cant just put it in the motherboard. temps are still wrong when i do that
-
Here's how you connect a regular thermistor.

@phaedrux thanks for the help as always. have just done it. temps are now ~280 so we we need another 90%hit! print head is stone cold.
M305 P0 R4700 T100000 B3950 (for the bed WORKS!)
M305 P1 R4700 T100000 B4725 C0.0000000706 (HOT END NOT WORKS) -
Is this an e3d thermistor?do you know the values to use for it?
