Beside the known procedures to increase adhesion with perforate plate ,that are almost mandatory (Abs juice), I noticed that a simple procedure gives great help.
It is just a matter of putting in pause mode the printer a little later the raft has been complete and wait some minute to let Abs cool down a bit .
Then resume the print.
Here is a part prone to bend at edges and at green arrows
If I understand lucamac, place the pause somewhere near the start of the print, but not at the the very start... like 5-25% depending on height of part
I notice a strong improvement in printing parts that are subjected to warping.
As I wrote , the Abs sauce trick remains as mandatory.
About at what moment insert the pause I have no objective reasons just my intuition .
I’m pretty sure that using pauses at the right moment and in the right number might be a major improvement for warping issues but there are so many factors that affects the printing process that it will be difficult to establish a rule , the “magic touch” of the operator will probably do the difference :D
the "magic touch" of the operator will probably do the difference :D
That's the point of that voodoo trick IMHO. A well leveled bed (together with an ideal contact for auto Z-sensing at print start) and repeatable environment conditions and a well treated bed is all up to the operator...
