New start

My bad but how do I fix it? ;)

Ok well if changing the settings isn't working then I'd suggest you re-install UCCNC. Maybe got a corrupted file or plug-in.?

Good morning!

Lovely day today, gonna tidy up some wires and see if I get better results :D

Any feeds and speeds tip for surfacing plywood with a 12mm 4 flute endmill hss.

Not really a suitable tool but the biggest I got right now :)
Have figured out that 1 or 2 flute would be better!

4500rpm, 4000mm/min 2mm DOC, full width.

Definitely not the ideal tool :)

Do not hurry now,try to get a bigger one,a bit with a cutting surface about 20 or more mm will save you much working time from the machine an d a better result.

Ofcourse ;)
That would be the smart thing!

I just want to flatten maybe 400x400mm and try to tram the spindle.
Will try to get better material than ply for my "real" spoilboard :)

I bought a 12.7mm 2 flute trend straight router cutter for wood and found it has a far better finish than the 2 flute carbide endmills I bought from China. The 2 flute carbide endmills leave an excellent finish with aluminium.

I used 18mm MDF which in the UK is the same price as ply but machines better and is flatter but you loose the ability to mist with oil for aluminium cutting.

Hmm dont think my spindle can handle 4500rpm. Standard Chinese 2.2kw thingy.. Will try 6000rpm ;)

Thanks :D

Ok, yes it will certainly not go that low - i have the same spindle and its useless below 8000, this is the issue with HSS - it needs low speeds or it burns up. Try and find a wood router bit - usually carbide tipped etc.

Bits for woods are better for this job,I found bits for metal at a very good price on flee market some months agoade in Germany and make some tests on several scrap woods, the results are not as good as the one I have with wood bit.
If you can find a bit at a good price with bearing at the end,take it remove the bearing and trim the insert point flat with a Dremel or a similar tool....

How are folks using these spindles for Aluminum (or are they)? I would think that even with solid carbide 3-flute endmills, 8K would too fast.
