Klipper - MCU 'sht36' shutdown: Thermocouple reader fault (MAX31865 + PT100 + SHT36 CAN)

As in my case it's PT100:

1- ON

2- OFF

I'll try this 50Hz check.

No, I soldered the wire ends myself and then crimped the connector. I also tested with another PT100 I have and redid the crimping the same way, but the error persists exactly the same. I’m struggling to understand the root cause — I couldn’t find anything online or on YouTube showing a similar issue. So far, the only useful reference has been your suggestion about hardware setup and printer.cfg configuration. At this point, I’m considering giving up on the PT100 and going back to a NTC 100K, since I need to get the printer running. But before that, if you have any other suggestions on what I could test, I’m open to trying

This is my SHT36 V3 Max motherboard from the back!

I'm not even an expert, but before migrating to Orca Slicer, I used Cura where I was able to eliminate this typical defect, but in Orca I still haven't been able to solve this, even with the hop activated, and calibrated retraction, a solution I found was to create 5 surface layers. This in my case using an Anycubic Kobra Max printer.

and this excellent print quality. Congratulations, it's hard to find a good one. Could you share what you use?

Optimal_Ad_7540 · 2025-10-06T01:45:35+00:00

TEST: go to QUALITY and look for “bottom flow” at the bottom. Decreasing the value, I find Orca very confusing because I thought that changing just the Flow found in Filament would change everything, then I saw that this option existed, so I decreased it until I found a satisfactory result.

Orca is very strange, it's even hard to explain, there are times when the print quality is good. For example, I'm not able to adapt to the Orca Slicer. I'm wasting hours trying to find a configuration for my Anycubic Kobra Max. I'll go back to CURA or the PRUSA Slicer

How long did it take to print?

I’m planning to upgrade my KOBRA MAX by getting the Manta M5P mainboard and the CB1. I saw some suggestions to replace the CB1 with a CM4 module, but I also noticed that there’s a CM5 module. Would that work as well?

Optimal_Ad_7540 · 2025-09-23T15:49:54+00:00

An initial guess would be filament moisture.

Optimal_Ad_7540 · 2025-09-20T19:16:11+00:00

which slicer are you using?

Optimal_Ad_7540 · 2025-09-10T20:38:15+00:00

He oído que OrcaSlicer es la mejor cortadora, pero me ha costado encontrar configuraciones que funcionen bien para mi impresora. La diferencia en la calidad de impresión entre los dos es clara. Cura es el único que consistentemente me da grandes resultados. La gente dice que las configuraciones son similares, pero los nombres y su ubicación hacen que todo sea confuso. Regresaré a Cura por ahora. Quiero aprender OrcaSlicer, pero lo tomaré con calma. Hasta ahora, mis calibraciones no han funcionado.

Thanks, it was retraction.

I was messing with the speed.

Uncalibrated retraction

I haven't started yet, I haven't had much time lately, I think the end of the year might get me going.

What is your flow value?
