Mach4 General Discussion / Re: Tool change Problem.

Hi Steve.

If I use the "T on M6 line is tool to use"my tool length keeps  changing as shown. Have you any idea why this is happening.

I think I may have discovered that the problem is not in the M6 macro at all but in settings somewhere

With Controller configured "T on M6 line is tool to use" I get the following results

If I take a single tool T5 and set the tool length by offset manually the offset is -14.9950 which is correct.
 
I then take the same tool and run:
T6 M6 G43 H6     The offset is -7.0150.   I then repeat the process incrementing the tool number and offset  with the following results.
T7 M6 G43 H7     The offset is -0.0080
T8 M6 G43 H8     The offset is -7.0150
T9 M6 G43 H9     The offset is -0.0080
And it continues the same

And it repeats. The small difference are probably  due to the touch plate not being fixed down yet.

Change to Controller config to "T on M6 line is next tool"

T13 M6 G43 H13   The offset is -7.0390
T14 M6 G43 H14    The offset is -7.0390


The difference from the manually set offset is 7.956  THE THICKNESS OF MY TOUCH PLATE is 8mm

I have the thickness of the touch plate is set in Probing Calibration and Touch. Have I forgot to set it elsewhere?

Thanks in advance

Thanks for replying but I had already tried that.  I had noticed a few replies on the forum saying that.
I updated mach 4 to V 2.0.4470 last night but no change.
It seems as if it is adding the previous offset to the probed tool length.
I am very new to this type of programming  (I was more of a hardware guy before retiring so having a hard time identifying the problem.

I have tried DAZ's m6 as shown on his video but it locks up on the first M6 command. This may be due to changes in the firmware since he wrote it.

Mach4 General Discussion / Tool change Problem.

« on: May 11, 2020, 11:27:10 AM »

I am having trouble with tool changes and offsets.
After finally making progress yesterday and being able to run a simple job on my new router I thought I had cracked it.

This morning I tried to run the same job and the dreaded tool problem started again.

The program calls the first tool m6 T10 followed by G43 H10, the spindle moves to tool change position and tool is measured and job starts. The measured offset is loaded into tool 15 of the tool table and the on screen the tool information shows T10 but offset 15. (the tool was cutting fresh air as T15 is longer than T10)
Tool 15 is the second tool to be used and it was the last tool change yesterday.
I decided to clear the tool table and start again.
This time the tool information showed T10 offset. although the table was cleared it had used the old T15 offset so it was cutting fresh air again.
I let it run until the next tool change m6 T15 again followed by G43 H15. The spindle moved to the tool change position but it did not stop to measure the tool but headed start back to start cutting. This time the tool info showed T10 offset 15.

I am using Mach4 Hobby  V4.2.0 4430.  should I update to a later version?
The M6 Macro is attached but it is the one from the NFS video altered to suit my machine.
The confusing thing is it worked yesterday.

Thanks in advance

Okay ignore the above post as I have just discovered if I put a pause in the line after the variables it is picking up the tool numbers.
Tool change now working but I have no idea what has changed from yesterday.

It is still not running the M6 macro but now I may be able to figure it out in debug.

Mach4 General Discussion / M6 Macro is being ignored

« on: May 06, 2020, 02:30:52 AM »

Hi everyone,

I have now completed my router and now about to start using it but  have discovered that it is ignoring the M6 macro  and the tool change is missed.
I have followed Daz's and artsoft videos on youtube etc but can not find the answer.  I have re-installed mach4 and tried everything I have found in the forum but no joy.
When I debug in zero brane the variables all show nill. It is not picking up the current or selected tool numbers.
Working with macros is new to me and I am more than likely doing something wrong.
Anyone have any idea what I am missing?

Okay nearly there.

I have reinstalled mach4 and ess using the SCU Application tool on the Warp 9 website with the latest versions of Mach4 and ESS plug in. All motors are now behaving perfectly up to 2000mm / min on 24v.  (I may increase the driver voltage to 48v later)

The only problem remaining is the feed dro is showing random numbers but on mach3 it is steady.

Hi Steve

The machine on mach3 can now feed up to 8000mm per min now.

My mach 4 machine only has a single ethernet port and no internet access in the workshop. I will drop him an email

I could not figure out what was happening so I decided to hook up the router to the pc driving my mill on mach 3 which has been running well for over 10 years on xp.

After configuring and setting up only 1 axis  on mach3 to test I can push the motor to just under 2000mm/min on 24 v and 3700mm/min on 40v. Feed dro quite stable.

It would appear that it is  mach 4 problem as this was with the ESS. Only other difference is mach4 is running in Windows 10.

Any idea where I could be going wrong?
