CS-Lab / Re: incremental encoder 10.000 RPM
« on: January 08, 2015, 07:14:05 PM »
Could you gear down the encoder /2 to make it work ??

Just a thought, (;-) TP

You would have to create a new PLugin to do it this way as there are NO current plugins to do this.

(;-) TP

That is basically HOW Torchmate operates. In G0 mode it is torch OFF and everything else is Torch ON.  No real advantage over doing it with M3/5 through the CAM. Does make it harder to read the code from the operators perspective.

What you are looking to do would HAVE to be done through a plugin or internal to Mach3.

To do it from CAM . ALL cams tend to operate that way. 

1684
Brian you really should start a NEW subject as to avoid confusing answers. I am with Striling I have used the THC for years with Mach3. I suspect you have other problems.  What controller are you using Mach3 LPT or other ??

Within the resolution of the Move value, yes.

Use the standard RefHome feature to find the switch then use a MACRO to inch the drive in the direction of the index mark Use a Do While LOOP to inch the drive untill it sees the index signal.

While Index SIGNAL <> 1
Code"G91"
Code"X.001"
Loop
End

General Mach Discussion / Re: Laser position sensor and mach 3
« on: January 07, 2015, 11:21:26 AM »
OK does the Controller plugin bring back the analog  value to a mach3 DRO ?

IF so then it is very simple. Create a Gcode program to do the XY motion across the part to be scanned then at each junction of XY read the XYZ values to a save file.

Just a thought, (;-) TP

General Mach Discussion / Re: Subroutines and passing parameters
« on: January 06, 2015, 09:29:26 PM »
Gcode is a motion control language in it basci form it doe NOT have logic. It is simple instructural code design to move a machine. It has evolve in some respects as to conditional Gcode . That has a basic logic incorporated.  It has not "EVOLVED" because it does not need to.

Yes Mach3 does subs to a limit. It does have some flaws to it.

IF you will post the working code we can review it and see what you have working.

G-Code, CAD, and CAM discussions / Re: G81 problems
« on: January 06, 2015, 06:47:57 PM »
I have seen somrthing similar to this before and it was a bug in the plugin for the DEVICE (software) Does it do the same thing with a G83 cycle or is it JUST the G81 call?  IF it is JUST the G81 call that causes the problem just don't use the G81 cycle (;-)

Ask the manf to correct the BUG in the plugin software.

Or just convert the machine to a ESS and be done with it. (;-)

Jkovar unless your controller board has an analog input and does A/D conversions you cannot read that type of signal directly in Mach3.

Now if your measure device has a serial output Rs232 or Modbus then you can get the result directly through Rs232 or modbus. Mach3 supports both of those funtions.

You could also use a MODIO to process the Analog signal and talk to Mach3 through modbus . 

Years ago we did a project with a laser range finder and MACH3 we use a MODIO to do the A/D conversion and talk to Mach3. Back then the resolution of the laser device we used was not good enough for fine detail work such as non contact probing .

Just a thought, (;-) TP
