Mistake True bed levelling G32

@sgk
I found the problem because of daylight, I don't know why with duet 2 it never does it to me and with duet 3 it does it to me. but even if I put a white sheet on the pei it does it do the same error.

@sgk IR probes aren't great with direct sunlight

@jay_s_uk
even with a white sheet. What can you advise me specifically?

jay_s_uk

@sgk i've never got on with them when i've tried them

A Former User

@jay_s_uk and what probe do you have?

jay_s_uk

@sgk on my machines now I use Euclid probes https://euclidprobe.github.io/ that can be picked up when used.
I have in the past used BFPtouches https://www.thingiverse.com/thing:2890290
I'm not a fan of normal bltouches as they seem to cause too many issues for people.
inductive can be good but you need to be able to adjust for temperature affecting the readings

A Former User

@jay_s_uk I agree with you the ones I had before I had bltouch and I also had only problems he only had the ir that it was fine but now that I am in duet 3 only problems too

A Former User

@jay_s_uk
this Euclid probes looks good to me but too complicated for me already that I have trouble with an ir probe or bltouch

jay_s_uk

@sgk you can also look at something like the klicky or unklicky

A Former User

@jay_s_uk
it's magnetized?

jay_s_uk

@sgk yes. klicky, unklicky and euclid all use magnets for attaching the bottom half of the probe

A Former User

@jay_s_uk it's too good this idea I imagine that it is necessary to program the printer and what to get the probe really quite complicated this part

jay_s_uk

@sgk the printer uses the probe as a standard switch.
there are example macros required for picking up and docking the probe so its fairly simple to implement

A Former User

@jay_s_uk ha but that's really what you're telling me, do you have any idea by chance where we could find it's macros?

jay_s_uk

@sgk the euclid ones are here https://euclidprobe.github.io/06_rrf3.html

A Former User

@jay_s_uk ok thanks

@sgk Here are my macro's for my Klicky probe it`s mounted on a Voron trident, but they are quite simple but will need to be adjusted to your printer but hopefully they help

@jumpedwithbothfeet
great thank you guys. it's possible that you make me a picture of your model to have an idea?

jumpedwithbothfeet

@sgk https://www.vorondesign.com/voron_trident my trident is no long standard it has 4 lead screws on the z axis even the klicky probe is not standard however the macro`s should give you an idea when you compare them to yours.

@jumpedwithbothfeet
OK great I see every time you feel the bed she will look for the probe that's it?
