Print bed leveling problem ?

[MontyFlange]

Ran through all the guides I could find.

It's level now, well small prints in the centre seem to work great but the adjust screws are right on the limit for bringing the plate down. The extruder nozzles are still touching at the front centre.

I have seen mention of 'shimming' Would this be to raise the extruders a bit I can undo the 2 screws holding them to the moving part and put 2 shims in there between the plate and the extruders. probably raid it .5mm

Would this then give me better control of the print bed ?

OK another 101 question. Printed out a few things now, mostly flatish things, Star Trek badhe, snowflake etc,using Makerbot desktop, All the prints are coming out very well. For me . So this time I try changing the settings a bit from the default. I upped the quality from medium to High then make the layer .10 and fill of 15%, there really wasn't much to fill. Anyway the raft is now imposable to remove. Would that be because of the quality setting and is there a way of adjusting that to suit ? Thanks

Not sure about your other question, but sometime's I get pretty stuck-on print's afterwords. I got a little plastic spatula that I use to help, if I really can't get it I use a butter knife to help pry it up CAREFULLY, but I can't say if that is a good thing to use or not -also I don't have a huge selection of tools yet- . Basically don't give up, just keep prying ;P

I let my bed cool first...and if it's really stuck give it a shot from a can of compressed air, hold it sideways so it shoots out some frozen vapour then the parts will pop right off

I'm a fan of the Fonzi method .. ie "Whack!!"

This is nothing about prints sticking it's about the bed not being adjustable. No idea where the sticking problem came from

[mikenmel08]

Because they thought where you said you could not remove the RAFTING that is stuck to your PART you were talking about your part bring stuck to your print bed......Selective Comprehension. .....I do not use rafting so the only help I can give is pointing the other people in the correct direction. .....
