I think all purchases of considerable size need sufficient due diligence, even from the UK.

Hi Martin,

You say your machine is low end, are you sure its capable of machining alum? You may find at 2mm depth of cut it may struggle. However assuming it can cope I would advise to stay with...

I think the point ger21 is trying to make is, is the quality of the cad data into the cam software good? If your putting faceted circular lines for example into c-carve then that's what you will...

I'm not entirely sure what you mean, but if your asking if do you need to be able to vary your spindle speed between cutters then yes absolutely..
Different diameters will require different rpms...

Super idea....

Hi Danny - I bought a 6090b from jcut a couple of years back, other than initial difficulty setting up the spindle in Mach properly (& some minor rewiring ) it's ran with zero issues ever since..!

Hi Walt,
I had a spindle control issue with my Chinese 6090, in my case I could not control the spindle speed with an m03, it would just ramp straight upto max. My fix was a rewire between the...

On my Chinese 2.2kw I use 15000rpm and 7000mm/min , 10mm carbide, 5mm doc. I started at 2000mm/min but found it was taking the edge of the cutters to quick as it was feeding too slow...

I think it's simply the fractional dwell that the tool takes when changing direction for those tabs, which is why I suggest to radial off slightly if you can.


Sent from my iPhone using Tapatalk

Look like dwell marks, I assume your running in auto and not single blocking?
If so try adding a radial in/out at these profile points , this will stop the minute dwell the cutter has on the profile...

Dave - does your "spindle setup" page look like matthews below?

Do you hear any relays click in when you command an m03 in mdi ?
