General Mach Discussion / Re: Dual head offsets.

NO you do not program G54/55 for EVERY hole you program it ONLY when you need to change heads(;-)

You would use G54 to do all the primary work required of that head THEN shift over to G55 (that shifts the 2nd head over to the work) then finish what work head#2 does.

Just a thought, (;-) TP

Well...my thinking is to make a hole and "call" the screw head, on every hole.....i mean, "hole, screw...hole, screw, hole, screw...and goes on.."....but maybe is more easy to make all the holes and after all the screws, but in my head this will make a longer machining time :/

That would work if each head had its own drive and mechanical assembly.  The call I am looking for is for both heads riding on the same axis.  That is, a Z axis with two heads.

I don't understand your case,  is not like mine?....my case is a router with spindle and on the same "plate" a pneumatic actuator, but this pneumatic assembly don't move on the Z axis with the spindle.

I don't know if it is proper to "ask in" on another's post.  If yes, then I apologize in advance. G54 accounts for X and Y.  How do you call, assuming both heads are riding the same Z. the extend and retract of each head?  That is one must get out of the way and the other must get to work.

To me there's no problem to make another question here, your question maybe help me too

In my case i'm using a "pneumatic extend" so i use a M8 comand (i know that's for coolant, but i'm using to active the solenoid for the actuator, but the answer posted by "Ya-nvr-no" make sense to me

Ok...i will try this 

I have to put this G-codes in every hole, rigth?....The code i posted here on my previous posts is not better?...I think with the another code i just have to put a tool change and the offset wil be automatically...

I have to program about 50 holes, so is a "pain in the a$$" to put this G54 and G55 on every hole  hehehe

Thanks!!!

Maybe this is the solution 

Another problem i was suffering is about "zero" the work offsets, is normal this dificulty to zero the work offset?.... I do it on the X and Y but on Z i can't zero, i try everything 

Thanks!!

PS: This machine is in another town, so i can't test this here, i have only a Mill with small travel course...

I read here this solution:

"tool = GetSelectedTool()
if tool=1 then
code"G52 x0 y0 z0"
end if
if tool=2 then
code"G52 x10 y0 z0"
end if"

Whit this code i don't need to repeat on every hole?

PS: I use Rhinocam to make the g-code, i'm newbee on G-code "by hand".

Hi!...My name is Glaucius, this is my first post, i'm from Brazil, so sorry my bad english 

My question is about programing dual head on mach3 mill, i will try to explain my case:

I build a head for a router, this head is for "screwing" a bolt on a wood and steel panel, is pneumatic and his base is bolted on the Z axis (on the plate of the Y axis), so they move only on the" Y" axis, they don't move on Z axis...

Well...i need to make a g-code to make a hole and after this the head put a screw on the hole, how a made the offsets on the more easy way?...I already made tool offsets on the Machturn and was "peace of cake", but in Mach Mill seens to be more complicated 

BTW, i need to make this process (hole and screw) about 50 times on every panel, so i don't wanna be putting a lot of "G52" on the code, there is a way to make this simple like in Mach Turn?

Thanks in advance!!!

Regards!
