Update and level X4pro & X4 plus.

There's one thing to be aware of with the Artilery X4 Plus, though. Unlike the X4 Pro, the latter has a manually adjustable platter with six screws and springs, three on each side of the platter, but it also has two aluminum spacers in the center. In my case, the spacers posed a problem that I'll discuss here.

As I show in these photos, I decided to remove the aluminum spacers in the center of the chainring because with these, the chainring ends up strongly bulging in its center or we will have to loosen the manual adjustment screws of the chainring so much that the latter will no longer have any support.

Before removing the two spacers, it was quite complicated to obtain a quality manual adjustment but once the spacers were removed, I managed to obtain a very satisfactory adjustment with a maximum difference between the highest and lowest value of 0.1588 compared to 0.285 previously.

You can then either manual level or use a software tool like Bed leveler 5000.

Using manual level first loosen the bed completely, heat bed to 65c.

Set Z offset using paper






















Then start winding the bed down slowly and evenly, 3 half turns front knobs then 3 half turn back knobs. until you have about 15 - 20 turns (you may need more)
Then redo the Z offset again. Run manual level, using paper on the 4 corners, remember wind slow and even. Run the auto level to see how the bed is on fluidd. if it is reasonable then start fine tuning the manual leveling again. Once happy remember to set Z offset before and after doing the Auto level.
