@dc42 I'm trying to have my prints auto eject, 30C seems reasonable especially with a fan blowing over the bed. Is there any other command that will allow me to run my eject script at a specified temperature?
I'm using a sheet of FR-4 as a build surface which releases quite nicely at room temperature, more experimentation is need before I can find the max release temperature. Quinly is using 27C
@phaedrux Just updated to 3.3 rc2 no change
Hi everyone, I recently converted my Voxelab Aquila (ender 3 v2 clone) to a duet 3 mini 5+ using the ender 3 guide and now
my motors a making a very strange sound. They aren't loud like the A4988, they are loud in the sense that they sound wrong. They sound like air leaking from a tank, but with a shallow high frequency beat. Its way louder than my other boards and sounds very wrong like something is not the way it should be.
The sound is only there during movement, the motors are dead silent during idle. Iv'e tried different modes with similar results e.g. M569 D0-3 ; M350 I0 and I1; and different micro step configurations
I did have issues with the 5v rail because Creality decided to mess with all wire colors on their version of the bl-touch but once I sorted it the board worked fine. I doubt I caused any damage but worth mentioning.

@phaedrux
Just found this under the 1.21.1 release notes
"If G30 was used to set an accurate Z height after mesh bed probing or loading a height map, if bed compensation was then cancelled then any Z offset from the height map remained. One consequence of this was that if bed probing was run again, the original height map Z offset was carried through to the new one, but the sign of the offset was reversed."
I'll try to update when I get home tonight
@phaedrux said in Z-offset increasing after a print:
e baby stepping constant
It's a d-bot 300x300 using this z setup (motors on the side) and an 8mm inductive probe on an aluminum bed covered with one of these build surfaces.
bondtech BMG Bowden with about 660mm PTFE tube
I don't know if mesh grid compensation is working or not, I have it configured in my config g and the bed probes. And I have G29 S1 in the config as well, so I think that's it right?
@phaedrux
My firmware version is 1.21 (2018-03-21) Yes, I have my z axis minima at -2 so that I can baby step and get around with my leveling issues.
Hi, my leveling isn't so in tune so when I start a print I like to use baby stepping, pausing and restarting and such to the the first layer right. but when I home Z after canceling a print the z offset increases by a millimeter or so. For example say my Z offset was Z-1 and my H parameter in M558 was 3, after homing I should see Z at position 4 in the machine status box. I do see this after a reboot/reset, but if I home after canceling a print that number increases to something like 5 or 6. the only way to get it bak to normal is to restart the board. If I try printing with this new offset the head crashes into the bed. also if I run mesh leveling in this state it will show the bed that much lower even though its homed first in the center of the bed.
Side note may be related, I can't seem to get mesh leveling to work. Its either over compensating, making some points higher or not working at all and its just my bed.
