Chinese 3040T Arrives

[JAZZCNC]

Second Cut On My CNC 3040, Using A 60deg V Bit.Drop Velocity to 1500 and Accel up to 600 and it cut the time from 1h 30m to 1h 15m and the motors seem to be ok.In the first cut video I used a 30deg v tool

Here's toolpaths suited to your cutters 30deg and 60deg but be aware they will cut much deeper has I limited the cut depth in the one you already cut.
These are full depth so you'll get more detail but will cut deeper and take longer so I suggest you have Mach3 do estimate run. I've put the depth in the name.

Hi
Thanks JAZZCNC I will give it a try

how to reverse the rotation of the spindle?

how to reverse the rotation of the spindle?

Why would you want that ?, the collet nut is designed to rotate forwards, i.e. it is trying to tighten all the time.

My is 3040T and the spindle is a ER-11

For my tools...

because the blades of the tool are down...

They cut in opposite side..

[EddyCurrent]

I've not seen those, all I've seen are 'up spiral' and 'down spiral' cutters but they all rotate in the forward direction.

Ok so lets first determine which way your spindle is actualy spinning.? It should be spinning in the clockwise direction does it.?

Can you show the cutters.?

[EddyCurrent]

Looking down on the machine all cutters should turn in the clockwise direction, same direction as a drill would. The up and down spirals are in opposite direction but they both cut in the clockwise direction.
Did you look at the link above to trend-uk.com ?
