@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

Phaedrux

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)

Phaedrux

Is this an e3d thermistor?do you know the values to use for it?

magdi

@phaedrux yes used the ones as advised on the wiki

Veti

no you connected a pt100 and configure a ATC Semitec 104GT-2. that does not work.

you need to get a ATC Semitec 104GT-2 or get the pt100 daugther board

@Veti it has been done before

so im confused now haha!
the dude got it to work with
;*** If you have a Duet board with 1K thermistor series resistors, change R4700 to R1000 to the following M305 commands
M305 P0 T100000 B4388 R4700 H30 L0 ; Put your own H and/or L values here to set the bed thermistor ADC correction
M305 P1 T100000 B4388 R4700 H30 L0 ; Put your own H and/or L values here to set the first nozzle thermistor ADC correction
M305 P2 R4700 H0 L0 ; Put your own H and/or L values here to set the second nozzle thermistor ADC correction
M301 H1 P10 I0.10 D100 T0.50 S1.0 ; PID settings for extruder 0
M301 H2 P10 I0.10 D100 T0.50 S1.0 ; PID settings for extruder 1
M570 S120 ; Increase to allow extra heating time if needed
M106 F10 ; Fix for Bigbox Blower

Veti

you just bought the wrong thermistor.
that config is not for a pt100 sensor that you bought

you got this.

you needed to buy this.

@veti im with you now!
thanks so much
will feedback once i get the new thermistors

ok whilst im waiting for the thermistors ive hit a new problemo, the z axis motors are not working.

currently i have two z axis motors and they're in parallel so two wires are connected to make one pin point (have tried singular connections too) .
have had them in driver 0 but they're not working.
have then re-pinned it to the E1 driver and managed to get the z to work so now i have all of the axis working yay. BUT driver 0 is still playing up. currently i have my other extruder there but its also not working. i keep getting a phase error as before for the Y driver. so the error, and no movement but every other driver works fine,

have done everything as advised earlier in the thread so im no sure what else to do in relation to this driver.

Phaedrux

For the Z axis motors you may want to return the wiring to be straight through for each motor and then connect to the Za and Zb motor connectors, which are internally wired in serial.

magdi

@phaedrux have tried that too but there was the same phasing error

Phaedrux

Are you sure you got the phase wire pairs matched correctly?

Yes they are correctly working in another driver currently in E1 abd working fine
