General Mach Discussion / Re: Macro for measure all Tool in toolrack Issue/Problem.

Today with more calm (this problems make me nervous  )...

I think when i have a crash/problem i have some M.C. incorrect, Tool offsets activated or deactivated (and other ones maybe).

First of all i need to start to watch the Modes in mach3, my screenset have a good info screen for see it and after every problem read the modes (i never have problems and i never started to understand/know all G codes, only the basic ones).

One easy solution (i think), in all my macros in the first lines add all G's "standard" for avoid problems (and maybe put a button in screen-set for set to default all for make it easier).

I go to make a list of the "correct  standard Gcodes for my machine" for use with ATC fully auto and use it sometimes "manually" (i go to try to put a button in my screen set for activate and deactivate the tool length offset's for the days i want make it all manually).


List of G-Codes i think are basics for my normal operation at startup, after something go wrong and maybe the G modes are incorrect:

G01/G90/G97/G54/G21/G15/G40/G17/G80/G49/G94/

G01 for avoid having rapid movements activated.
G90 absolute coordinate, i think i never need G91/91.1/90.1. In normal mode and in macros i can't find any different G9X (better to add it for avoid problems, the macros in theory have all necessary G's for change it if it's necessary).
G97 constant rpm mode (i think this is the S********* for control spindle speed)
G54 it's my normal WC, but the tool setter use another one for tool measurements (better if i add this standard work coords for avoid problems.).
G21 (metric units)
G15 (Carterian coords i think i never use a polar coords.)
G40 Cancel nose radius compensation (with my cnc/atc/toolsetter i only use tool lenght compensation, for safety cancel all other compensations).
G17 XY plane select (i don't know for what reason but in my mach3 mode i have this G17 now and i search info and i see G17 it's the standard i use).
G80 (cancel canned cycles, i never use it, but for safety...)
G49 (cancel all tool offsets compensations, the macros for measure, touch, post processors have G43HXX for activate it and for avoid crashes after bad tool measurement or anything else maybe it's better if i activate it with the macros/gcodes).
G94 Feed per minute mode (i think i never go to use G95/96/97, but safety first...).

Optional ones??:
G64 continuous mode (constant velocity mode)
G50 reset all scale factors to 1.0 (i don't know if this is necessary or its good for safety)
G99 R-Level return after canned cycle (i have this G99 activated in my cnc in this moment i don't know if its normal because i dont undertand what make this Gcode)



Anyone know more "safety" codes for my case or see this lines correct?

All help/comments are appreciated.


Thanks to @ll

I post here my two macros actually working when i used alone.

(i changed the names because i can't post files with same name).

Today i have some time and i tried to see how it works the "ATC with tool offsets" i made a zero in a bed table and do a tool change to another one and with my pendant see if the bed table have the same 0 (for see if the tool offset works).

When i tried i see doesn't work (i don't crashed nothing, because i do it manually).

After this i tried to start the tool setter macro another time, after the first tool measuring the tool goes directly to the to of Z+ and the machine stops (alarm of the closed loop steppers).

After the crash to Z+ i closed mach3 and started another time and i referenced all home axes.

And i click to the tool setting macro another time for measure all tools. After this, disaster the spindle go down full and another time alarm.


I see I'm very lost with the G options settings and i think i have a lot of things wrong with my mach3 settings and macro's maybe.

After the last crash my G settings actives are:

G15 G0 G10 G17 G40 G21 G90 G94 G54 G49 G99 G64 G97 (i don't know before this what G's are actives).

I started to read this gcodes and i see i need to activate G40 (this one i think it's obligatory for me, because i don't want tool compensation diameter) and i need to start to use the G43/G49 for the tool offsets (maybe if i used this the first try this doesn't happens but maybe it's good for learn how to solve this problems and have a good config).


If anyone have time to help me to put the correct settings in the mach3 setup, or see if my two macros have issues with G's and this make weird things i'm be really appreciate.

I start to share in this post and next one the screen shots and macros.

Thanks to all for your help i really appreciate your effort.

I made some changes in the code because toolrack doesnt close (i copied the variables of pin11 and 12 in the start of the program) and all works.

I made 6-7 repetitions with two tools (tool 8 and 9, the closest tools to the tool setter) and i think it's good.

In the logs i see deviation of 0.025mm maximum in various repetitions, for a non industrial CNC it's a good probing or maybe need to try to improve? (i don't know the real precision of the cnc's).

OMG it's this GetVar2002 have problems with my controller or mach3 version (i don't know) but i changed it and teorically all work good.

I go to test more times in the air and try it with calm when i finish i go to share the code (nots my code its from Bo Andersen).

i think your machine was in incremental distance mode (G91) and not in absolute distance mode (G90)
when you run the macro.

I tried to see what happens,with g90 (the error i reported in first message it's because the first time after trigger soft limit all mach G's are crazy after restart mach3 3 all worked, not worked but no g53 errors).

When i start the macro with tool 3 inside and say to the prompt what tools i want to measure i say tool 3 and 4 (for make it quick without need a tool change or anything).


The machine go to probe position, i set a random position near me for control better all and trigger the probe by hand (i don't use ISO holder and tools, i don't want to break tools).

When start probing and go down (with low speed, 50mm/min - 25 mm/min) and i trigger the probe the machine go to rapid movement and crash in Z+ (go up and crash).

In the log i see the Getvar 2002 = say 200.31875 and i observed all times i tried this getvar are the same. I think this is incorrect because for what i read getvar 2000-2002 are for read x y z positions.


In my z touch plate macro for set 0 in top of my workpieces (wood) i see the ZProbePos are GetOEMDRO(802)

In my ztouch plate macro have an update in the macro info and say this:

REM (5 August 2021) Custom Version GetVar(2002) replaced With GetOEMDRO(802) As GetVar appears To be unsupported In some hardware.


I go to try to modify this getvar in the code and try to identify all places with this getvar for change it.

I paste my z touch plate working code if anyone need one (one day i need to make a post only with working macros, but first i need to see it's working perfectly).

General Mach Discussion / Re: Macro for measure all Tool in toolrack Issue/Problem.

« on: May 29, 2023, 10:25:08 AM »

i think your machine was in incremental distance mode (G91) and not in absolute distance mode (G90)
when you run the macro.

Thanks, i go to investigate more and try to change it i know g90 g91 but i don't understand correctly how it works/affect .

Hi to @ll, and first thanks for your help.


I tried to use this macro i found in youtube.

Explanation of the code:
https://www.youtube.com/watch?v=duULYFBjDnk

Showing how it works in real life:
https://www.youtube.com/watch?v=SLq_s0FQ-SA


When i use this macro i have one problem with G53, i think i don't have a mistake in the code (i copied all the code and see if it's correct 2 times coping the video).

The Log say this:

Code: [Select]

Sun - 19:53:46 ---Cannot use g53 incremental , Block = G53 Z-6.5
Sun - 19:53:46 ---Cannot use g53 incremental , Block = G53 Y900
Sun - 19:53:47 ---Cannot use g53 incremental , Block = G53 Z-10
Sun - 19:53:47 ---Cannot use g53 incremental , Block = G53 Z-5
Sun - 19:53:48 ---Cannot use g53 incremental , Block = G53 G00 Z0.0
Sun - 19:53:48 ---Cannot use g53 incremental , Block = G53 G00 X780.61Y1103.32
I don't know if its something relative with the settings in mach3 maybe i go to share my settings.

Anyone can help me to make it work, if you need more captures of my settings or something for see if my settings are correct tell me and i make it fast.

Thanks for your help.

General Mach Discussion / Re: Return tool to tool holder when finish working.

« on: May 28, 2023, 04:41:39 PM »

I post the current working ATC macro with Pneumatic Tool Rack.

This ATC macro for the moment uses only 2 output pins and if you put in mach3 "M6 T0" (call tool 0)  the tool return to the tool holder, i want to put the tool holder in place every time i finish working (works with the current tool, if you have the tool num 2 the tool2 return to tool 2 position in tool rack).

Output 11 for Open collet and blow air at same time for clean the cone and the tool holder (my CSMIO controller is limited and i don't want to use two separated outputs for Opening the tool clamp and blow air)
Output 12 for Pneumatic tool holder

For the moment i don't go to use the Tool sensors, i have some problems with one of the sensors and i want to see with more time if the other sensor works correctly all times.

I tried to comment all lines in the code for help to understand how it work.



For the moment works perfectly without issues. 

This code are possible with the help of TPS and Graham.

Thank for your help i really appreciate your efforts.

General Mach Discussion / ATC spindle problem with sensor (manufacturing problem)

« on: May 10, 2023, 05:04:06 PM »

I upload this video of my new 1.8Kw ATC spindle with issues in one of the tool sensors, only work the sensor when the clamp are opened but the sensor for see if the tool is inside fail (see the video).

This motor is from Rattm motor / Powace (it's the same company), when you buy a spindle in Aliexpress china if one of this issues happen you are done and need to learn how to repair yourself.

The assistance is non-existent with excuses like "ISO20 you need to use another tool holder with different stud".
I send this video and say to him, this issue is without a tool inside and the reply is "if there is no signal without the tool holder that is normal, as we only have two signal Hanging and putting knives, so don't worry."

The seller doesn't really talked with the technicians and doesn't understand nothing about this spindles.

After this no more responses from the seller.

For the moment i don't go to repair this because i don't want to disassemble the spindle without a manual (o see video of another ppl disassembling the same spindle).

I go to make the macro for ATC only with clamp open sensor in the checks of the macro.

With time you can see how evolve this spindle in my videos and if i have luck and i don't have more issues (the spindle feels good except for this problem).

Here i post a video for see this issue (short video).

https://www.youtube.com/watch?v=MDXX0MyDeL8

I think i right to think this isn't good no?

Tomorrow maybe arrive the rails (12mm non hiwin rails) and start to try the macro.

Thanks another time for your time.

Have good time and give me some luck with this ATC
