Pinda temp calibration
I launched temp calibration of my pinda sensor. It last forever on step 6/6 (several hours). What can I do ?
Re: Pinda temp calibration
I resolved the issue by putting an isotherm hood on my printer. The extruder temperature didnt managed to achieve 55c without that.

What is an "isotherm hood'?

Cover it with a box.
Put it in a cupboard.
Just find someway to stop cool, ambient air wandering through and preventing the Pinda getting warm (and stable) enough.

A fancy Styrofoam cooler. or a typo for a fleece hoody. 😀

Hmm, my prusa is an enclosure. No need for a hoodie.

Re: Pinda temp calibration
On a more serious note; you can also avoid some of the PINDA thermal errors by waiting for the PINDA to reach a minimum temperature before running the bed mesh. Add this somewhere in the Printer Custom Gcode.
M860 S35 ; wait for PINDA temp to stabilize
This makes most of your first layers very consistent. Here's what my Anti-Ooze startup code looks like:
M115 U3.4.0 ; tell printer latest fw version
M83 ; extruder relative mode
; Warm up bed, nozzle, and PINDA
G28 W ; home all without mesh bed level (cold zero to get PINDA near bed)
M104 S185 ; set extruder partial temp
M190 S[first_layer_bed_temperature] ; wait for bed temp
M109 S185 ; wait for extruder temp
M860 S35 ; wait for PINDA temp
G28 W ; home all without mesh bed level (hot)
G80 N7 ; mesh bed leveling (N7 = 7x7 on non-Prusa FW, ignored on Prusa FW)
; get nozzle away from PEI for last bit of heatup
G91 ; move relative
G1 Z10
M109 S[first_layer_temperature] ; wait for extruder print temp
G1 Z-10
G90
; Purge line
G1 Y-3.0 F1000.0 ; go outside print area
G92 E0.0
G1 X60.0 E9.0 F1000.0 ; intro line
G1 X100.0 E12.5 F1000.0 ; intro line
G92 E0.0
M221 S{if layer_height==0.05}100{else}95{endif}
