Why is my build plate z level getting messed up

[wirlybird]

Do you suggest to set them both to 0?

220 and 80 as an temperature of the extruder and HBP?

I might research the settings a bit. It seems one may be telling it to start the supports a little to high for the first layer.

I run my bed at 65 for the first couple layers then to 60 and that is with a glass bed. As for extruding I run from 190 to 210 or so.

Going to try both values at 0 and a layer height of 0.1mm for the support structures to make it go a bit slower, might help. Will let you know how it goes.

As far as my temperatures, I have used 220C and 40C for the build plate and it has always gone fine.

Thanks for the help, will let you know how it turns out.

I definitely think it's more of a software issue than hardware maintenance now if you were able to print something without supports just fine without any filament issues.

Here are my settings from S3D which I've used for quite some time, maybe they will help:

I just tried it again with these settings:

But still failure, as soon as it reaches the supports the build plate and the extruder gradually get separated by a centimeter or so. I don't know what to do. So as soon as the print reaches the part where it will start the support structures: this part:

The extruder and build plate are not closely together (shown in the video)

Thanks for the information. It sounds like your software is generating G-Code that has some really weird settings for the support as I don't see anything in your config that would make me think your print would mess up like the video.

I've never really encountered anything like that in S3D and hope someone else more knowledgeable in that software may be able to assist.

If you haven't yet I might go post this out here.

This is a good area with a large volume of people with a wide variety of experiences and equipment.

One thing I haven't heard anyone bringing up is a possible issue with retraction settings. If you're printing with retraction, try turning it off for a test print. It could be that adding the support structures adds that many more retractions to the print, increasing the chance of extrusion failure. No QIDI printer here, but I thought I'd throw that into the mix of possibilities.

Halfway through the print, a gap of air between the extruder and the actual print is present. I don't know why:

My settings are:Filament: PLA
Extruding temp: 220C
Build Plate temp: 40C
Layer height: 0.2mm
Shells: 2
Extruding speed: 40
Speed while extruding: 40mm/s
Speed while moving: 60mm/s

I use Makerware as my slicer

Also, in this picture there are empty spots in the first layer? Could that be an issue?

the empty spots are because at that point the extruder is too close to the build plate to extrude. ie, the build plate is not level.
Now this will cause a build up of molten filament in the extruder the will change how it prints the next bit of the layer.
In other words just having the bit of the bed not level could well effect the entire print.

Apart from your print temp being a little high for pla (try 210), settings are fine.

But your build plate is definitely not level.
