Dave, did you have a look at the PDF I posted a forum page or two before?

(I'm out of ideas)

HIYA RObert , the problem with a lot of those articale is they were developed using a very high end plasma NOT you basic DIY with a low end air plasma unit. 

Your best friend at this end is TEST AND TUNE and keep good records.

Yes, thanks, i have seen that before but as TP says, its high-end stuff but i guess some of the info will down-scale to our size equipment.

what would be really useful is a standard test piece  that could be passed around forums so results could be compared - it may be that 90% of what we all seek is not possible and if everyone got the same results on the same part it would prove it.

just a thought.

Well I'm sure we all have one, I'll post mine later, a 2" square with two radiused corners at opposite ends of different radius with a large hole in the centre and a smaller hole off to one side with a rectangular tooth shape cutout....

It's what I always start off with, with new plate or setup to test.

It tests everything shapewise I will throw at my machine except long cuts, or really thick cuts.

Bread and butter for me is 1.5mm to 4mm, occasional 6mm but I'm not into armour plating my real hobby (landrover)

Keep working toward turning hobby into business...  paycut from dayjob... But may be more enjoyable.... Retirement business maybe in future.

Already trying that idea

Care to post up your file?

Here is my submission for the Test piece.

Hmm, odd, do you scale that when importing ??

Tried it here and sheet cam says it 6mm wide by 5mm tall, might need surgical laser to cut that one

6" x 5"?

My offering here... (in mm)

Yep good old inches, D'oh!

Got both files cammed up and will be testing them saturday.

Post results pictures here or elsewhere?

Thanks

Ohhh... I never cut the small hole.... It was on there to sort of see how small a hole you can make... Give it a go if you wish though
