3d solex matchless upgrade for ultimaker 2

Recommended Posts

Posted · 3d solex matchless upgrade for ultimaker 2

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.

Yes using the Matchless V3 , but did not change the 25W heater.

Should have try the 35W heater.

Currently can print but need 230 deg for PLA vs 220. and also slower print speed.

Tried both the 0.4 and 0.6mm nozzle - 0.6 mm perform better.

Will change the heater later

Are you sure you have inserted the temp sensor and heater cartridge as expected? Maybe check that.

Also, the Stainless steel nozzle is usually 0.5mm and not 0.4mm

There are now 0.4mm Stainless Steel Nozzles.

Are you sure they are Stainless Steel and not Chrome plated Brass Nozzles?

It may not be stainless steel after all.

I have changed to the 35W heater. same problem have to print at 235 to 238 for PLA

Have not upgraded the feeder though. It keep skipping during print.

The PTFE coupler is a new one.

I suspect it could be the new filament I purchase from 3DXTEXT.

Have been using this filament for almost 1 year without problem.

There are no stainless nozzles in that kit.

I would suspect that you damaged your temp sensor when replacing the block?

I have reverted back to the original nozzle .

Print temperature is still have to set at 235 to 238 deg C.

Infill speed have to be slow down.

Suspect it is the filament problem. Getting back to 3dxTech.

Thanks everyone for the info.
