@veti Good spot, thanks
I have altered my thermistor to suit what I am using.

What does the T0; Select first tool do?

Hi all.

Please can someone run through my code. I have a duet ethernet and a duex 5. Printer is cartesian style with
1 X motor
2 Y motors
2 Z motors
BL Touch and a Titan areo extruder.

I was thinking of using motor stall as end stops but decided against it for now. I would like to have limit switches for both x and y axis at both ends. I have added an 'E-Stop' section for the max limit switches as software should stop the printer going past the designated area.

Here's my code and thanks in advance

Had a good read and think I know have the right motors on the way.

Any recommendations on best methods for extending cables for

Steppers
Heaters
fans
thermistors

etc

@dc42

Thats brilliant thank you.

THank you for the rapid response

I think ill go for the both then, for redundancy and more control.

Any recommendations on stepper motors

Currently thinking 0.9 degree, using nema 23 for the y axis and possibly z and then nema 17 for everything else

Hi,

Looking at replacing my ramps. Its a large format printer with build of roughly 800 by 800. I have a titan areo extuder with a volcano nozzle. I am struggling with heating enough filament so want to use a 24v system. ALso want the benefits of wireless printing and a more reliable board

I want to drive

1 - X motor
2 -Y motors
2 - Z motors
2 - Extruder motors

Is the best way to run the dual motors in serial from one port? Or can I drive them all individually using the expansion duex board? If so How do I do this. I checked the configuration tool and I can add extruder motors but not axis. Although adding an extruder I can change the end value to be an axis (I think)

Thanks in advance
