My nozzle is touching the raft when printing


Hello everyone.
When I print the raft, my nozzle is constantly touching the areas already printed.
I have the tray well calibrated, the perforated platform is new just like the nozzle.

Hello PedroVieira,

Despite the fact that the platform is brand new, could you pass the calibration results? Also, have you tried increasing the platform-raft gap in Z-SUITE? This should resolve the problem. Let us know the result.


My M300 does this for most materials as well, just on raft layers 2 and 3.

For calibration, currently the rear two contact points and center are all at +0.1, and the front points are at 0.0.

It improved a little after taking apart the bed and cleaning out the plastic between the layers, but now I adjust the raft flow ratio to 85-90% and it usually doesn’t happen. I tried once at 80% but experienced under-extrusion and a failed raft.
