Andre,
I am sorry you are still having problems.? It appears your issue is tied to tool height compensation.? I suggest you experiment with limited code until it is worked out.? When I was learning I used a cardboard box as my table height so I could change tools and have time to hit E-stop before I struck the bed if something was wrong.
I have observed in your discussions you include diameters.? I suggest until you work this out you forget diameters and only pay attention to lengths.? The easiest way to have the problem you are describing would be to be using the offsets screen incorrectly.? Are you using the offsets screen at any time?
I have an hour or so if you are available now.? Please describe how you have determined tool length, how you have set your lengths into the tool table, and how you have numbered your tools.
Charlie.

Hello,?

Do you have a limit/home switch on your Z axis and do you home the machine
here each time??

Do you have an ATC?
If not, how are you setting Z zero?
You can probably remove the G43 from your code and it should get rid of the problem.

The same code I tested 2x and worked fine. Then on tool change it start to hit the z-limit switch again
This is almost textbook for a system with Z axis trouble. When the axis drives into the material, it struggles and steps get lost, this causes a most annoying and confounding type of problem, in the air all is fine, in material you hit the Z upper limit switch over time. The test for this is simple, run a program that drives the Z up and down several times and moves in the X after each Z up and down. Run this in the air 10 times, then see if Z has lost anything. Then run it in material 10 times, where the Z has to cut the material on each downward plunge. How often out of 10 times is it out of position in the Z at end of program? If the AIR run is clean, and the material run is not.. you have a problem with your Z.. Sometimes its the speed is too high on the retract, meaning your Z tuning is set too high. ( Personally, when seeing this type of problem my first move is to lower the Z max tuning speed by 50% as a test. If that doesnt fix it I then turn down the Z plunge rate in the GCode by 50% to see if that fixes it.. I rarely get further than those two tests before the issue shows itself. If GCode runs properly in the air... and doesnt in material, the problem in 95% of cases is the machine, not the GCode or Mach3. Ive seen this error literally thousands of times over the years, the problem....and its ensuing frustration remains the same. :) , Mach3 still has many bugs, most known, but it runs the same from run to run in 99.999% of cases.. so in your case, Im betting on a mechanical / tuning issue...

HI Charlie / Guys ? Well let start by giving specifics of my setup and work process. Then I will show some of the code ? My CNC is using a new PC with 4GBRAM and windows XP – dedicated to Mach3 only. My bed size is x=3m long, Y=2m and Z have total travel of 170mm I use a manual tool change spindle. ? My limit switches in on all 3 axes. And also on the extreme to make sure I do not try to over run any axes. ? My Z-Axis I home on top so I move in negative values. ? I always start the machine firs by starting the PC and mach3, then start the CNC control board and reset. Then I Reff all and make sure all axis are then zero. ? I also made sure that my Tool table is blank. ? I lately tried to use the Calypso MachStdMill screen set because the tool change sequence is great. ? On my table I have a fixed location for tool change with a fixed plate. The fixed plate is on Z=-167.454 (Measured to the gauge line of my spindle) ? I have a specific start position for my work and use this position as my work coordinate offset X=80.4310 Y=0.0000 Z=-95.0716 ( This offset is measured using my Master tool) I have a master tool that I know the length and always inert this tool first, touch it off and make sure the length is know. This tool is tool nr 200. With the tool length then measured, I then go to the offset position, enter the offset values and make double sure the offset is perfect. Then I zero all the axes. ? I always zero on top of my spoilboard. ? Then I start loading my code. ? Now getting to the code: I did run this code 2x at the same x and y coordinates, the Z coordinate were higher to make sure I do not cut any material. And both times it worked fine. Then I reset my axes and start the code to cut. And it start hitting the z-limit ? This error I have now for 3 weeks Previously, I had the tool diameters in the tool table. But then when I executed the code, it keep on hitting the z-limit switch on top. This happened for example with tool 1. I then changed the code only to use tool 2 and not the tool table. So in the tool table the tool diameters were still there. Then rerun the code and it worked. The same happened with tool 2. When I start the program with tool 2, it gave the same problem and then when I edit the gocde and change the tool to tool 3 it worked again. Then I removed all the tool settings in the tool table and tried all the codes again and first time all of them worked. ? One thing that I did notice as that the rapid clearance of my machine when executing the code is always going to Z-Zero position. ? Here is a few lines of the code that is giving me the problem. ? % O0001 N10 (PROGRAM PRODUCED? - 13 FEB 15) N20 G21 G90 (UNITS METRIC) N30 G40 G91.1 N40 T05 M06 G43 H05 N50 S12000 M03 N60 G0 X1038.7 Y267.206 N70 G98 G81 X1038.7 Y267.206 Z4.

Agree 100% with Art.
I would also suggest, that it may very well be an acceleration issue rather than a top speed issue.
Especially with steppers.
The way machines must be tuned, is for the worst case, rather than the typical, or average, case.
This means that especially for stepper (direct) driven machines, you need to use lower acceleration values and lower top speed values.
Because in the case where you are entering (leaving) material, while moving, in some cases the load is larger than the current settings allow .. thus leading to lost steps.

?? Try one test.. lower Z accel to 10..
run your job. If it runs fine, ( I suspect it will), raise Z slowly till you see

From then on you should be gold.

Andre,
I am sorry you are still having problems. It
appears your issue is tied to
tool height compensation. I suggest you
experiment with limited code until
it is worked out. When I was learning I
used a cardboard box as my table
height so I could change tools and have
time to hit E-stop before I struck
the bed if something was
wrong.
I have observed in your discussions you include diameters. I
suggest until
you work this out you forget diameters and only pay
attention to lengths.
The easiest way to have the problem you are
describing would be to be using
the offsets screen incorrectly. Are you
using the offsets screen at any
time?
I have an hour or so if you
are available now. Please describe how you have
determined tool length,
how you have set your lengths into the tool table,
and how you have
numbered your tools.
Charlie.

This is almost textbook for a system with Z axis trouble. When the axis
drives into the material, it struggles and steps get lost, this causes a
most
annoying and confounding type of problem, in the air all is fine, in
material you hit the Z upper limit switch over time.
The test for this is simple, run a program that drives the Z up and down
several times and moves in the X after each Z up and down. Run this in the
air 10 times, then see if Z has lost anything. Then run it in material 10
times, where the Z has to cut the material on each downward plunge. How
often out of 10 times is it out of position in the Z at end of program?
If the AIR run is clean, and the material run is not.. you have a problem
with your Z.. Sometimes its the speed is too high on the retract, meaning
your Z tuning is set too high. ( Personally, when seeing this type of
problem my first move is to lower the Z max tuning speed by 50% as a test.
If that doesnt fix
it I then turn down the Z plunge rate in the GCode by 50% to see if that
fixes it.. I rarely get further than those two tests before the issue shows
itself.
If GCode runs properly in the air... and doesnt in material, the problem
in 95% of cases is the machine, not the GCode or Mach3. Ive seen this
error literally thousands of times over the years, the problem....and its
ensuing frustration remains the same. :) , Mach3 still has many bugs, most

I dont have a good recommendation, in numbers for You, at this time.
Please let us know what steppers/drivers/bob/motion control You use,
and we can look at similar machines.
But, and this is * very important*, it differs greatly, by 200-300%,
depending on;
- hardware pulses or not, such as a CSMIO or Pokeys hw output, vs PP
= Parallel Port
- volts used on steppers. Higher = more acceleration
- size and type of stepper. Bigger steppers = slower top speed,
slower acceleration (more impedance = slower)
- what driver You use. Good drivers can deliver 20-30% more results
in terms of acceleration and top speed
- what motion hardware is used. Linear guides, v-rails, gibs all
have different profiles
- direct coupled = (much) less acceleration
Inertia matching is very important.
For example, my mill table is very, very heavy, (200 kg table, upto
100 kg vices etc) compared to most built by the owners.
It makes no difference, to me, because I am using a 1:3 belt drive
(3x the torque), and a good hardware motion control, and linear
rails (THK and Hiwin), and ballscrews.
-48 V DC, nema 23 steppers, chinese 542 series drivers (after gecko
251s), Pokeys, 1:3 HTD 5 mm 15 mm wide belt drive
With the PP driver, I would expect less acceleration, lower top
speed. About 30% less.
With integrated low-voltage bob/drivers, say at 32V, I would expect
to have 1/2 the accceleration and top speed, or 100% difference to
current
With gibs, expect 30% less acceleration and top speed

This is a very good system.
( I would drive the z axis at 1:3, for more 300% torque =
acceleration.)
Try Arts test at the lower acceleration, and let us know.
It will likely make a difference, or lead to clues on where the
problem is.

I have starting to change the acceleration and started the test runs, will continue to run tomorrow as well to see if the acceleration caused the trigger of the limit switch. Could be. ? But one thing I noted even in the test runs – the Z-axis continue to go to Z-Zero position between cuts.

( I would drive the z axis at 1:3, for more 300% torque = acceleration.)
Try Arts test at the lower acceleration, and let us know.
It will likely make a difference, or lead to clues on where the problem is. On 17/02/2015 15:04, 'Andre Schoonbee' andresch@... [mach1mach2cnc] wrote: ?

Go back and see my post from earlier, and the one from Charles. I'm pretty sure the G43 is causing your issues.

I was reading your set up and one thing that caught my attention is you are zeroing your Z to the table, is Vectric material set up with Z- zero at the bottom of your material?
