Hello,

is it possible to home the E axis with a microswitch endstop? This is part of my config.

; Axis and motor configuration
M569 P0 S1									;Drive 0  (Eaxis)										
M569 P1 S1									;Drive 1
M569 P2 S0									;Drive 2

I want to add an endstop to de 0 and 5 drivers but both of them are tools and i'm having lots of problems.

Thank you

@cosmowave @cosmowave I will study this option.

But what worries me the most is that i want to implement this safety system because once i send this m106 p0 s255 gcode to power the leds. If the software that i use to print or my board bugs i can't manage to send the power off gcode on time. Thats why i wanted to control the temperature the led reaches once i turn them on. In that moment is when i want to control that and when it reaches hight temperature (because something on the software/board went wrong) i can turn them of without damaging anything.

@cosmowave I'm using RepRapFirmware for Duet 2 WiFi/Ethernet 3.2.2 (2021-02-11).

The fact is that i want to use this as a safety disconection system.

I want to do something like this:

M106 P0 H0 T70; Send this gcode to power up the LEDs but when the sensor measures 70º to force it to stop working.

In case that the system is working properly i will use the M106 P0 S0 command to turn of the relay.

Hello,

I need help for a project that I am carrying out.

I am using the output of a fan to drive a solid state relay. This relay activates or turns off some LEDs that do not have to be on all the time. That's why I need to have control over its on and off.

If the leds get too hot they can cause an emergency.

I have chosen to use the thermostatically controlled fans. I bought the board to be able to use a thermocouple. I have managed (using a fan to see it graphically) that it turns on from a specific temperature. But I would like it to work the other way around: that when the sensor measures a temperature higher than a limit value, the FAN OUTPUT TURNS OFF.

Could that be possible? Thank you

@dc42 Thank you for your response. I've found that my problem was related to my fw version so it does'nt work properly. Now i read my position without any problem, but i would like to know if it is possible to read the position from one axis neither than from all the axis as the M114 does. Thank you!

Hello everyone, I'm using the sensorless homing for the X axis.
On my GCode routine, once I've done the homing process and the position is stored to 0 (forced by the G92 X0 code) I would like to move that axis till the opposite and with the G1 H3 parameter stop the movement and store my new position.
Once I use this H3 gcode parameter, my Duet 2 allows me to move along the axis but ignores the real position of the machine, but it never stores to the new position o in the case I home the axis again it never turns back to 0. Can someone help me?
Thanks in advance
