Why is my build plate z level getting messed up

[fontseeker]

I am printing with PLA, I tested it again with another print with supports and without supports. Every time I print with supports this problem appears, but without support it prints perfectly. Does anyone recommend any settings for Support structures on MarkerBot or does anyone know what I am doing wrong with supports?

Never used makerbot but my guess is maybe it just isn't good at supports? Might try a google on that one.

I have seen Makerbot printers work perfectly with supports but it is my first time using a QIDI, for some reason every time it gets to the support the printer starts printing midair, like it didn't place the supports but the building plate keeps going down:

In other words, the print goes flawlessly, but as soon as it reaches the support structures, the extrude slowly starts to print midair. No idea why

This are my support settings:

I can't figure out what it is that is messing my print when I use supports.

Some one can correct me but look a the support margin, support to model spacing and support to roof. Seems like the first or second one could be to big. In S3D the separation between the support and lower is 1 layer thickness and same for the top. Also 220 and 80 are on the upper end for PLA.

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.

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.
