Mach4 General Discussion / Re: X move starts before Z move finishs

« on: July 22, 2019, 09:31:56 PM »

I have tried the G61 and it cures one problem but  it is so jerky doing compound curves etc that I can't use it
Also doing hi speed cut outs with G64 it cuts external 90 degree corners fine but internal corners 90 degree corners it puts  a large radius instead of a sharp 90 degree corner and this radius is related to the speed of the feed  so to my mind is not following the tools path  and I think it is impractical to put a G61 before every internal corner and a g64 after and don't think the post processor could figure out to do that either 
So I am at a bit of a loss how to tackle the problem
I am using a router and feed of 120 inch per minute and need to get down to say 6 IPM to make is follow the desired tool path

I use mastercam  and I looked through and  it is putting a G64 at the start of the code
Thanks I will test a G61 out tomorrow  but am pretty sure you have the problem solved thank you very much
I think in the past in high feed  moves I was getting larger radius on internal radius machining but could never figure it out so I think that will be the same  problem   
Regards Ray and thank again

Mach4 General Discussion / X move starts before Z move finishs

« on: July 20, 2019, 08:17:00 PM »

Hi
I am having trouble a Z feed does not get to zero before the next command starts to move and  it seems to be feed dependant
G0 Z .25
G1 Z0  F55
X2.2 F100
this will start feeding the Z value until about .020" .030" before Z reaches zero then the X moves begins leaving a  .150  to .200 long ramp
If I slow the Z feed down to say just 4  it seems to feed all the way down  then do the X move
Do I have some thing set wrong some where
Regards Ray Hudson

You will be pleased to know I have renamed the STOP button the JESUS button so there will be no confusion
Lucky for me and other Mach4 users it is totally configurable  so this was easy to do   with Mach4  you can easily  get the machine to do what you want and how you want it done

Thats fine this is a thread about programming the stop button and that has is already completed and now every thing works as I want which is the only point to this thread
Mach4 does not need a M00 as the are at least a dozen ways to achieve that if that is what you want   to set up your machine

Hi
I think you are missing the point
I did not want to just turn of the coolant
I wanted to do a stop
  turn of the spindle
  Retract the tool to machine zero in Z axis
  turn of the coolant and the air to the mist
 and or the extraction system off
 return machine to X and Y machine zero
 then do a reset of the Gcode
in that order

Why any one would want to write Gcode in the controller is beyond me unless you are doing the simplest of parts or don't have access to a drawing program  and even then   you have the MDI for  set up moves and simple parts any complicated part will need to be done in some thing like Mastercam etc

  More than half the professional controllers out there still have to have a usb or serial communications   this way I have  wifi and instant communication

Having used many systems in the real world and had maybe 30 different cnc machines in the last 30 years in my own shop I think Mach4 is the best thing since sliced bread

I am new to Lau  and learning as I go still the time I spent was still maybe 6 hours in total but and I must stress this the help I have received has been fantastic and a reason in itself to  buy and use Mach4 

Well that is it  for this thread  the problem is solved to my satisfaction
Thanks again to all who helped me come to the solution that I wanted

Hi
The feed hold did not do what I wanted  though I could have configured that button to do what I want but I wanted the feed hold button to do what it does  as I do use it on occasion the stop button was the only logical choice to program up  though I did consider just adding a new button  this would have been in fact much easier to implement but not what I wanted
I have a few  cnc lathes etc with commercial controllers on them so have seen both sides I have  Mach4  on a commercial  router that I retro fitted   with a PC and tool changer   at least I can make the mach4 do what I want and need  I did look at buying a commercial Controller for the router  a GSK was going to be my choice as I have used these with great success  and like them but the mach4 leaves them in the dust

Hi
I wanted to do a  few more things including turning of the coolant   and from a stop I would never restart from that point but I am sure A lot of people in fact most people it works just fine for them as it is and would be the standard way most controllers in the commercial world work  But and a big BUT
Mach4 is really configurable and I think just fantastic and are sure you can make it do what ever you wish I just wanted some thing more than what most people would want am are still learning the Lua script  though I did write the script for  a 8 tool rotary tool changer and that works great but this I could not at first find where and how to edit what I wanted but Mach4 help is the best bar none

I have run the machine and low and behold it now works perfectly I have done a few moree modifications it now returns to home and resets the Gcode I had to run coroutine  a second time to allow the moves to finish 
I use M9 in the command instead of playing with turning off the output directly

I have to say a big THANK YOU  I do not think I could have figured it out by myself  and it for me just makes a already great machine just that bit better to use for what I am using it for
Thanks again I  never recommend Mach4 highly enough it is just fantastic and the help received invaluable

Thank you is now works in simulation mode 
I will try it on the machine tomorrow
I will let you know how it goes but it is looking good
Thanks
Regards Ray
