3d solex matchless upgrade for ultimaker 2

Recommended Posts

I have bought the 3d Solex olssen block upgrade for my Ultimaker 2. It comes with 0.4 stainless steel nozzle.

Have problem with printing PLA at 220 deg C. Temperature have to set at 235 for filament to flow.

Also infill was not printing correctly. Previous original ULtimaker 2 nozzle and filament was ok.

Anyone have any idea that the heater must be upgraded to a higher power?

Do you have the Olsson block or the Matchless V3 like your title shows?

Also why are you using a stainless steel nozzle for PLA? Stainless steel nozzles have bad heat transfer and are not suited for PLA.

They are not even good for abrasive materials. E3D Hardened nozzle and the Ruby nozzle are a lot better.

If you have a UM2 then I would recommend upgrading the heater. The UM2 has a 25w heater and UM2+ has a 35w heater.

If you want to print with the big nozzles like 2mm then I would get the 40w.
