I don’t know Replicator 5th generation BUT it is definitively a first layer adhesion problem. As it has been said: the only bluetape which will work is the 3M 2090 (any size). Do not use other blue tapes like Tesa. It is too smooth to handle prints.

I remain at your disposal for more information.

try the BuildTak bedding: www.buildtak.com 42. We have no issues at all with sticking and you don’t necessarily need heated bedding. The only moments we have issues, is when we have to print flat items (approx 3-5mm thick), then there is the curling of corners happening, for which I still am looking for a solution

Buildtak, bigger raft (try 8 or 10 mm) and Z-axis manual offset - take the build plate closer! Printing without raft is always troublesome. Printing on blue tape should not be a problem at all unless you are printing things that are as big as build plate.

No need to ramp up the temp at all. It wont help in this case. Is this a rep5, mini or Z18? It looks like the extruder homed a little too far from the build plate. If so, it can be adjusted in MakerBot desktop. You need a nice squish on the first layer. Just to note…each extruder may home to a slightly different height. If you are swapping extruders youll have to do a test print to be sure your z-offset is correct if your want to print raftless.

Adjust the Z-probe offset. Or do this.This is what I do. It was from another post, intended for another person. But it is a quick and dirty way to fix your issue.

Don’t ramp up the extruder temp!!!

You’ll destroy your extruder… if temp goes over 245° you risk to damage the PTFE Tube inside…

I had this issue on my flash forge dreamer. It turns out there was a SLIGHT blockage (Contaminate) in the feeder tube inside the heater block. I was able to pull this apart and remove the contaminant and it worked beautifully.
