Hi there!!! the setup is complete!! hopefully everything goes fine with this configuration, i just moved the 4th axis putting the conector in the extruder´s driver and works fine so far. i put the pictures here to see the mechanical configuration, and if you have any questions for the development of the firmware just let me know.!

Hi, i just checked it and it was this, thanks for the help,you guys are giving a really nice support

Hi there!!!
a bit late but here goes my setup:

Hi there everyone!
I´ve been using duet boards for some years now(i already have 3 of them on 3 custom printers).
and i was wondering that technically this machines can be used as a measuring tool.
One of my printers is retired now but, if anyone could give me a hand with the development of the firmware, i could modify it to use it a n automatic three coordinate measuring tool.
What are your thoughts about the idea?

@o_lampe
I was referrig to a pretty expensive machine that exist already, they use it to measure acurately. it has a sensor where the extruder would go, and touches the part, for measuring.

@CVMichael i can´t see the video

@droftarts
Can anyone help me? it is still giving me the same error.
i run m303 several times, then m500 and still same error when powering on the printer.
Thanks

@droftarts
You are rigth, all the problems started when i upgraded the firmware.
It was giving me errors when heating up the bed. i runned m303 several times, try to do some changes and didn´t work and i changed the heating element for a more powerfull 220v silicon one. the bed itself is 460 in diameter, and yes, it takes a while to heat up.
i run m303 back again to show the results, and see if we can get someting out of it.

Hi there!
Every time i power on my delta printer puts "bad model parameters" on the screen.
And a warning that says heater 1 predicted maximun temperature at full power is 660C.
This is my output of m115 :
m115

And this is my config.g
config(1).g
Can someone please give me a hand?

@deckingman I just changed the "T" parameter and looks like it is working fine no. thanks so much

By the way, every time i power the duet it says "bad model parameters".

@droftarts there you have it :
