PINDA problem don't stay in a vertical position horizontal to the bed
Hello,
I'm having problem with PINDA probe, no matter what i do the sensor doesn't stay vertical (horizontal to bed), the plastic support have a slight angle.
Screw or unscrew the PINDA angle is the same.
I'm felling this is affecting the probing because i can't get a perfect first layer no matter what live Z i use, if i print a 60x60 square the left side and bottom side come with the little needle holes near perimeter, other sides come good but surface is not even on the printed object. If i lower live Z to fix one side, other will be too low.
This happen with a bigger object too at same sides
All images was print at same start PINDA temp 35ºc, to discard temp variation
Can that pinda angle causing the problem?
Note: I print lot of ABS and some times pinda goes up to 90ºc and PETG can soft and drop, so not sure

It should be parallel to the bed. The fact that is at an angle is highly concerning. I would look at the probe holder to see what is going on. I guess that a replacement will be needed. Contact chat support for this unless you have another printer or a friend is close that can print the part for you.

My MK3 is not new, i have some good print hours with that. But now this is happening.
I'm able to print, is not invalid, just hard to get a perfect layer.
I may reprint the body but in ABS this time.
The plastic holder looks good from eye prespective but i can notice a angle, still is not melted or something like that

Oi Tiago,
Our warranty is good for 1 year so this might be covered by the warranty. Material fatigue? Dunno what happened but I'd check with chat support and they might be able to help. But if you prefer the ABS route then go for it. :ugeek:

Does warranty cover plastic parts after usage? My pinda probe have broken on a wire after some usage, i contact support and they send me a link to buy a new one, they told me thats only covered when you buy the assembled version, so i guess for the kit we are a little by our own
As i told i print ABS often, pinda reach more than 90ºc, that can be the cause. That temperature + m3 screw tension + pinda weight may deform the PETG holder
Example of temperatures After 12m: Recv: ok T:240.0 /240.0 B:120.1 /120.0 T0:240.0 /240.0 @:35 B@:59 P:90.8 A:48.6

Hello,
i have exactly the same problem ... what could be the solution ? zero problem with mk3 but now with mk3s i have lot of problem with ABS prints particulary with "wall" and "last layer" and switching from ABS to PLA for self tests and z-layer calibration is annoying 🙁

Sure sounds like minor melting of the Pinda holder. ABS will fix that, if you can print it.

That is sagging due to the PETG extruder body being exposed to high temps. Happens if you print a lot of PETG at high temps or even more likely with PC prints. Happens more if you tend to print a lot of fairly flat objects where the print head stays near the print bed for a long time on the lower layers. Reflected heat softens the PETG PINDA bracket and it sags sideways like that. Only solution is to reprint/replace the extruder body part. Prusa has a R5 version of that part (and the extruder cover) with somewhat beefed up support which is supposed to last longer. What I did though was to reprint the parts in PC which has a higher temperature tolerance. I'm hoping that makes it last. An alternative is a version of those parts done by Bunny Science. His version also has made the lower part of the body removeable so only it can be replaced should it melt. By the way, this issue seems primarily to happen on 3S machines which have closer tolerances for the part. You'll probably also want to print extra fan shrouds as they also suffer sag issues.
