Model not "Sticking" to the plate

I have been printing for another 20 hours with the blue tape so far and had the tape lift once but the prints need a scraper to lift them. I get 3-4 prints out of a layer of tape before it's trashed by the scraper.

I had issues initially with the first few layers not adhering to the bed. Tried Pritt stick but that just got scoured by and then clogged the nozzle.

A better solution I found was to mist a light coat of spraymount onto the bed (with the hot end cold and/or remove the flexplate and spray it away from any heat source... spraymount is flammable!)

No problems now, everything I've printed (c50 assorted prints) since has been fine.

I put some Scotch Blue painters tape down and it stuck really well. I use it for little things but my larger items I watch the first few layers and use a little tape on the skirt if it lifts

Also try printing slower. Without my heated-bed I had to slow it down to 25mm/s. Once you start figuring out all the right adjustments, you'll be able to speed it up a bit.

Print my Beta Z

Hi, thx for the replies :)

I have found out the reason , the base layer is sticking to the plate (with PritStick)

The actual issue is the Z axis movement , it is not moving up in small movements , but will with large movements so the print head is crashing into the model. Ill look at the forum for Ideas as its the old alignment issue .... erghh

It's very likely that the first layer isn't low enough. On the first layer the nozzle should be squishing the filament down onto the platform. I recommend lowering the offset by 0.1mm increments and see if that improves things.

Do you have the heated bed? Start with 50-60c on the bed. If you don't have a heated bed and you've tried PritStick then I'm kinda out of my element.
