Keep getting this strange behaviour from the machine.
Just keeps stuttering, even when just going along a straight path on 1 axis it will judder a lot.
Does it every so often and most of the time I have to turn it off and on again.
Any ideas?Derby MakerSpace coming soon! >> https://derbymaker.space/

Sounds like chatter to me..
Avoiding the rubbish customer service from AluminiumWarehouse since July '13.

Correct it is resonance. Either lower your rpm or up your feedrate.....a lot. This is where having a machine with no rigidity and physical weight plays a big part and restricts what you can do, there is only so far you can push a machine like that.

Just noticed my RPM was 12k not 6k xD

Not sure what I am doing wrong here.
It worked before but for some reason is not now...
I am cutting out some holes for some components in the rear of my case.
I am using a 4mm roughing bit to do this (the rough edges help in this case).
I have my part upright in the vice and around 1015mm clearance luckily.
Here is what it is showing in F360.
Here is the Gcode;

The tool Z height is set to the top of the part, and Mach3 confirms this. But Mach3 plunges the bit into the part.

Seems strange that you have a Z5 then a Z4.6 (I would expect this to be ve value) I see you have tool length comp on with the G43 Z15. H2 is this correct in your tool table..Clive
