Hi,
I have a very weird problem and I broke too many end mills in one week. Here's the problem:
- I start a program.
- Mach4 pauses on tool change.
- I manually change the tool, move Z axis to position then click I click "ZERO Z" button.
- Then I click cycle start to continue the program.
- Program continues and the Z axis dives into the part and crashes.
I tried the same code on my cnc router with Mach3 but it works good.
The tool change line in the code is:
N115 T2 M6 D2 H2
Note: The M6.mcs is attached
What could cause this?
Thanks in advance,
Suat

Forum wont let me attach the M6.mcs file somehow. But here it is:
function m6()
local inst = mc.mcGetInstance()
local selectedTool = mc.mcToolGetSelected(inst)
selectedTool = math.tointeger(selectedTool)
local currentTool = mc.mcToolGetCurrent(inst)
currentTool = math.tointeger(currentTool)
if selectedTool == currentTool then
mc.mcCntlSetLastError(inst, "Current tool == Selected tool so there is nothing to do")
else
mc.mcSpindleSetDirection(inst, 0)
--Remove this line if you would not like the Z axis to move
--mc.mcCntlGcodeExecute(inst, "G90 G53 G0 Z0.0");--Move the Z axis all the way up
mc.mcCntlSetLastError(inst, "Change to tool " .. tostring(selectedTool) .. " and press start to continue") --Message at beginning of tool change
mc.mcCntlToolChangeManual(inst, true) --This will pause the tool change here and wait for a press of cycle start to continue
mc.mcCntlSetLastError(inst, "Current tool == " .. tostring(selectedTool) .. " Previous Tool == " .. tostring(currentTool)) --Message that shows after Cycle Start
mc.mcToolSetCurrent(inst, selectedTool)
end
end
if (mc.mcInEditor() == 1) then
m6()
end

OK I added a quick video.
In the video I used a simplified g-code. It starts with a drill operation. After drilling is complete (at second 0:42) Mach4 pauses and waits for me to change the tool. Once I change the tool I move the Z Axis to the location then I hit Zero Z. Now I hit Cycle Start to continue then I expect the Z axis to go and stop at -1 but it actually goes to -33 (and crashes).
It is really annoying and I need to know why Mach4 does this.

Hi,
my only guess is that you have tool length offset active.
I notice that while you change to tool number two, the tool length stays the same as tool one.
Try putting a g44 at the top of the code and try again.

Hi,
just had a much closer look at your video and you have a line:
N50 H43 H1 Z2
That's where your tool length offset is being applied. Tool length offsets work really well PROVIDED you keep clear in your mind what offset is being
applied at any given time. If you don't keep a track of it the DON'T use them.

Hi,
I can see two lines, N50 and N140, they both have a g43 in them. Do you really intend to use tool length offsets?
Your zeroing procedure is like my own, because I have a manual change mill I have touch off each and every tool,
and I zero the z axis but specifically DO NOT USE tool length offsets.
With an ATC mill each tool is measured and ascribed a tool length offset from the master tool and stored in the tool table.
Each time that tool is called and fitted into the machine you use a g43 hnnn, where nnn is the new tool number, and that tool length offset
is applied such that the tip of the tool is exactly where the tip of the master tool would be. Is that want you want
to do?. If not then get rid of any and all g43's....they will cause crashes UNLESS you specifically require them and use them as intended.

Hi Craig,
Removing G43 from the code didn't help. Then I've removed whole N50 and N140 but didn't help too.
-
Very interesting. I did a fresh install on another PC and it does the same. I removed G43 and also tried to add G49 but it just behaves the same.
-
Hi,
Try editing this line:
N115 T2 M6 D2 H2
Remove the D2 and H2, they apply the tool length and tool diameter offsets.
Craig
-
Hi,
Still the same.
Are you able to do a test for me? I just wonder if it works for you.
Run the code,
on M6 jog the Z axis down then ZERO Z.
Hit cycle start and see if Z axis goes and stops at -1.
Thanks in advance,
Suat

Hi,
look at the diagnostics page. If a tool length offset is applied it will be listed.
Clearly you have a problem with offsets.

Hi,
No offset output in the log:

OK guess what! I downloaded an earlier version from here https://www.machsupport.com/ftp/Mach4/DevlopmentVersions/Mach4Hobby_Installer-4.2.0.4385.exe
And it works as it should. So is this a bug in newer versions?
-
I uploaded a new video. Mach4 version in the video is 4.2.0.4385 and it works perfect.
So my new question is what is the different between the latest Mach4 and 4.2.0.4385 that causes this problem? Is there a workaround I can apply to the latest version I have in my machine? I need to use the latest because I have lots of custom things in it. I mean I can't simply give up the latest and use 4.2.0.4385.

I tried all these builds. I can confirm that the build 4582 and previous versions are good. I mean removing G43 works on these builds however the problem starts on build 4584 and remains. The latest build is also buggy.
4385 good
4524 good
4543 good
4559 good
4566 good
4563 good
4580 good
4582 good
4584 bad
4596 bad
4682 bad
4744 bad
.....
4824 bad (latest build)

Please open the docs folder within Mach4. Read the document called "Tool Offsets Mach4 Mill"
This goes into extreme detail on setting up single and multiple tool for use while running G code files.

Hi,
The doc says:
"Once the tool change is complete in the MDI tab, enter G43 H1, and hit Cycle Start. This will activate the tool offset for tool 1. These
commands can also be on the same line."
I do the tool changing manually so I don't use G43 but Mach4 keeps behaving there is G43 in the code. When there is no G43 in the code Mach4 moves the Z axis down and crashes.
Have you watched the two videos I posted?

Am I the only one having this problem?

This M6 function seems to be working fine. I found this code from this video: https://www.youtube.com/watch?v=tCU1bzuDNvI (https://www.youtube.com/watch?v=tCU1bzuDNvI). I simplified and removed some unnecessary (for me) code.
function m6()
local inst = mc.mcGetInstance() ;
local currentTool = mc.mcToolGetCurrent(inst)
local selectedTool = mc.mcToolGetSelected(inst)
local posmode = mc.mcCntlGetPoundVar(inst, mc.SV_MOD_GROUP_3) --get the current mode so we can return to it when macro ends
--Get positions before moving to do tool change
local valX, rc = mc.mcAxisGetMachinePos(inst, mc.X_AXIS) --Get the position of the X axis in Machine Position
local valY, rc = mc.mcAxisGetMachinePos(inst, mc.Y_AXIS) --Get the position of the Y axis in Machine Position
local valZ, rc = mc.mcAxisGetMachinePos(inst, mc.Z_AXIS) --Get the position of the Z axis in Machine Position
if selectedTool == currentTool then
return
mc.mcCntlSetLastError(inst, "Current tool == Selected tool so there is nothing to do")
else
mc.mcCntlSetLastError(inst, "Change to tool " .. tostring(selectedTool) .. " and press start to continue") --Message at beginning of tool change
mc.mcCntlToolChangeManual(inst, true) --This will pause the tool change here and wait for a press of cycle start to continue
mc.mcCntlSetLastError(inst, "Current tool == " .. tostring(selectedTool) .. " Previous Tool == " .. tostring(currentTool)) --Message that shows after Cycle Start
mc.mcToolSetCurrent(inst, selectedTool) --sets the current tool displayed in mach to the selected tool
local probedz = mc.mcCntlGetPoundVar(inst, 5073) --this retreives the Saved varible of the z position (#5073) in machine coordinates and assigns it to the name probedz
local ToolLength = math.abs(9.5238 + probedz) -- this calculates the value of the tool lenght by using a gage line off of my spindle to the tool setter. uses the absolute value fuction
mc.mcToolSetData(inst, mc.MTOOL_MILL_HEIGHT, selectedTool, ToolLength) --- this sets the tool length value into the tool table into the selected tool position number, Note - i havent reassigned current tool varible so i have to use the "selectedTool" name
mc.mcCntlGcodeExecute(inst, string.format('G ' .. posmode))--return to pre macro mode G90, or G91
end
end
if (mc.mcInEditor() == 1) then
m6()

In the meantime Rob send me an email with an M6 function. I tested it and it worked fine too. Only difference from the stock M6 is it has an extra line which is:
mc.mcMotionSync(inst)
Since it is official I prefer this one.
Thanks Rob
function m6()
local inst = mc.mcGetInstance()
local selectedTool = mc.mcToolGetSelected(inst)
selectedTool = math.tointeger(selectedTool)
local currentTool = mc.mcToolGetCurrent(inst)
currentTool = math.tointeger(currentTool)
if selectedTool == currentTool then
mc.mcCntlSetLastError(inst, "Current tool == Selected tool so there is nothing to do")
else
--Remove this line if you would not like the Z axis to move
--mc.mcCntlGcodeExecute(inst, "G90 G53 G0 Z0.0");--Move the Z axis all the way up
mc.mcCntlSetLastError(inst, "Change to tool " .. tostring(selectedTool) .. " and press start to continue") --Message at beginning of tool change
mc.mcCntlToolChangeManual(inst, true) --This will pause the tool change here and wait for a press of cycle start to continue
mc.mcCntlSetLastError(inst, "Current tool == " .. tostring(selectedTool) .. " Previous Tool == " .. tostring(currentTool)) --Message that shows after Cycle Start
mc.mcToolSetCurrent(inst, selectedTool)
mc.mcMotionSync(inst)
