Topic: misc parts lifting same corner of bed

having problem with one spot on bed.   Using glass bed with aquanet hair spray, temps are set to 215 and 105 and abs filament.   problem is the items(different 3d parts) are warping on same spot on bed.  Have sprayed the glass with ton of spray but that corner is still coming up my prints. have calibrated to the best of my knowledge.    Any help would be appreciated

Re: misc parts lifting same corner of bed

A ton of spray can be problematic. 
Try flipping your glass over to rule out the glass as the cause.
Verify that there isn't a clod spot on the bed and that there isn't a draft in that area of the platform.
Also it always helps to squish the first layer as much as possible.
The problem may not be related to the bed at all and could be the result of a bent rod or something else that is out of calibration.  If you set the nozzle so it just touches the glass on one side it should be that way everywhere on the glass.  If it's not you have a bent rod.

Also check the Z-offset in slic3r profile.

I adjusted the screw when I put glass on and  change the offset in slicer also offset is set at .15

Re: misc parts lifting same corner of bed

is there a good video on how to adjust screw with the glass on.  Right now I set by just guessing on the turn

Re: misc parts lifting same corner of bed

Set that offset to zero then start a simple print job with a good skirt or brim.  I use a circle and a single skirt line and start and kill the print during the skirt.  Each time I adjust the screw until I get a nice flat line on the glass.  This will also tell you if the bed is level in relation to the nozzle movement.  I also decrease the flow of that first layer so it doesn't curl (get wavy) on a single line.  What you want is a line that is about 2 times your nozzle diameter on that first layer.  I find that decreasing the flow of that first layer allows for amazing adhesion to the glass without over extrusion that can mess up the second layer.

Re: misc parts lifting same corner of bed

I put Z offset to 0 and added brim, so far so good.  I appreciate the help!

No problem glad it is working.  If you get everything right you will have to pry your part off the glass unless you let it cool first.
