It shouldn't matter, at least I don't think so for the more common bed leveling probes. The induction sensor and most mechanical bed leveling probes don't actuate based off of the tip touching some point, but rather the external probe sensor itself, so they won't be prone to error caused by the nozzle expanding.KC_703 wrote:Any concern about expanding hotend affecting the leveling?
I usually "time" the start of my print to ~10C before the hotend reaches the first layer temp. Its worked well so far, but this is a great addition to the start script.
I had a couple of concerns with the setting for my Ender 5 Pro.alien2108 wrote: ↑Thu Nov 06, 2014 5:21 pmHey thnx for great tip!
I actually did following now:
- Disabled the Wait for Temperatures to stabilise
- Startup script I changed as as following:
M140 S[bed1_temperature] ; Set bed temp and do not wait - preheat
M104 S150; Set extruder and do not wait - preheat
G21 ; Units to mm
G28 ; home all axes
G29; Detailed Z-Probe
M190 S[bed1_temperature] ; Set bed temp and wait to be reached
M109 S[extruder0_temperature] ; Set extruder temp and wait to be reached
G1 Z3 F1000 ; Slide the probe back in
G1 X10 Y10 F6000 ; Move to start of bed
So this means that in the process of auto bed level bed gets heated up and extruder preps to 150C. After auto bed level is complete (G29) everything is heated up to final temperatures.
Saves me A TON of time now!!!
