[Cura 3.2 Won't drop nozzle to Z offset]

Out of sheer frustration, I sliced the part again in Cura and S3D and ran the start up of each one on my machine.  BOTH worked normally!  I apologize for taking up your time.  I have no earthly idea why I had bad results on the previous compilation.  I need a good bottle of cabernet!!!

 

Thanks again.

Oh, I had no Idea that's what you wanted!!!  No problem.  I'll put them in WordPad and send them to you shortly!  

 

Thanks

I don't use the G92 command in the starting GCode.  I was using Simplfy3D before seeing all that the new Cura has to offer and I thought I would give it a chance.  As for the Marlin I use, it is 1.1.0 RC3.  That's not the latest version but it's working so..................    With S3D, an old version of Cura from 2 years ago and Repetier Host, I never did anything to have the nozzles drop down to the offset amount set in the firmware on EEPROM.  This 3.2 version seems to somehow remove that command or ignore it.

I posted this in the wrong place.  I think it should be in the Ultimaker Software section.  Do I cross post it or can you move it?  I don't see where I can do it.

 

Thanks!

Yes, something is definitely in there telling it to ignore offset command.  It homes G28 fine.  Under Preference/Printers/Machine Settings that is a topic "Gantry Height".  This one is a mystery but, perhaps, you have the option there to set an offset???

[Cura 3.2 Won't drop nozzle to Z offset]

I have just installed the new Cura 3.2 and tried it, after selecting the staggering amount of options!  I copied and pasted my starting and ending GCodes that have been working fine for two years.  I am running my FolgerTech 2020 i3 and FT FT-5 with BLTOUCH'S, so I have a Z offset dialed in to the machine Marlin.  Normally after the G29 command completes, the nozzle with drop to the zero position, hesitate and then go down the Z offset distance.  Now with Cura, it drops to Z=0 but never drops the offset amount before starting to print.  

 

Is there a setting deep within the Cura preferences and disables the Z offset?  I would think that since it's in the Marlin firmware, that Cura would have no control over that, yet if I go back to an older S3D print, everything is fine.  

 

What am I missing, please?  This is my starting GCode>
