Larger build size of 300*300*400mm plus the reinforced design of diagonal rods form a stable triangular structure, which can effectively reduce vibration and achieve more stable printing.

I can't understand why they moved up to a pro edition is it because " PRO" is more tempting than LK5 or is it a marketing strategy. Upgraded Dual Blower Kit】LONGER LK5 Pro Upgraded 3D Printer uses the newly upgraded cooling fans, dual blower kit which can promote rapid cooling of the extruded filament, powerful cooling nozzles can make the model surface better and smoother. This is the first 3D printer I have used that has a triangle structure Z brace and a high-temperature resistant Teflon Bowden tube. If the item comes direct from a manufacturer, it may be delivered in non-retail packaging, such as a plain or unprinted box or plastic bag. The open-source motherboard is equipped with three sets of TMC2208 ultra-silent chipsets for quieter printing.Or you can use adhesion promotors, like hairspray, Elmers glue or any other additives but not SUPER GLUE!

I suggest printing at 200 degrees or perhaps 210 degrees and then moving forwards from those results.How cool is it to print a model that once it’s finished, it moves around from its articulated joints. The Longer LK5 PRO is packaged well with thick pink foam and has been cut to ensure minimal movement. LONGER LK5 Pro uses dual inclined rods to hold the z-axis as a steady triangular structure for a better quality of 3D printing.
