G54 work coordinate - best practice

[a.sooriasegaram]

Hi,

I've come across a few video tutorials now where the recommendation is to edit the NC file and remove G54 coordination system from the G code - instead inserting G,0 Z,10 for example to guarantee the cutter raises up high enough to clear stock before traversing in the x & y planes. I'm not familiar with G55 coordination but I usually always start from bottom left corner of the stock at the stock's top height.  Only once have I encountered the tooling not elevating to the correct clearance before traversing and scratching the surface.

Would appreciate your suggestions on this.

Thank you

G54, G55 are what's called "work offsets". They tell the controller where your part is located on your table and allow for multiple jobs or Setups to be run consecutively. Some controllers (the lower end hobby grade) don't have functionality that allows for this.

What machine and controller do you have?

If you home the machine properly this isn't needed...never heard of this in over 10 years

Hi Seth,

Thanks for your help. At work we're using a Colchester Clausing 4VSQ MillPWR G2 with the accurite millPWR G2 Console.

It's a bit intimidating to be honest! My own hobbyist machine is a Shapeoko XL with software from Carbide 3D.

@seth.madore This is a funky control from the looks of the Manual.

After looking at the manual for this control, I understand what you were saying in your initial comment.  It appears the control does not recognize G54 (or any traditional WCS command).
