Thank you.

Thanks for the replies, I will stop worrying. I see the daughter board is using a MAX31865 so I presume you use the spi connection to read temp. Several sources sell a MAX31865 based interface card so, just out of interest, could you connect using the expansion header ?.

I would like to convert all wiring on the x carriage to extra flex to remove the possibility of cable breakage. I want to use a pt100 temp sensor on the hotend. The pt100 output is tiny and subject to noise so to reduce the pt100 cable length I can easily mount a small signal conditioning chip to the x carriage and connect to the duet using extra flex. The output is an analogue voltage proportional to temperature. My problem is that a direct analogue input is not supported in the list of temperature sensors.

Is this possible ?

Many thanks, I have been wading through the duet documentation but not read that bit.

I believe that using a home command causes the axis to move to endstop, reverse for a set distance and then move to endstop again at a lower speed. If this is correct are there any parameters available to set reverse distance and speeds ?

I realise I can use a macro to detect the endstop and move accordingly but more elegant to use existing parameters if available.

Many thanks.

I am in the process of building a new machine but would like to test the hotend heater and fan(s) without having any other components (steppers, stops etc) connected. Will the board allow this or do I need everything installed ?.
