General Mach Discussion / Adding A Tool Length Sensor

« on: March 22, 2016, 04:55:41 AM »

Hi everyone,

What configuration do I need to get this tool length sensor to work correctly in Mach3?
http://cnc-step.de/en/products/accessories/1156-zero-point-switches-tool-length

I have already entered the pin information under the Ports and Pins page and Mach3 sucessfully detected the sensor.

Does the sensor require a script to run?
If yes, do I need to enter the dimension of the sensor in the script? The touch plate on the sensor in is attached to a spring that will depress when the tool touches it. Do I need to find out the travel depth when the plate is depressed and enter that value into the script?

Thank you?

General Mach Discussion / Mach3 Limit switch triggered and ignored

« on: February 03, 2016, 06:14:09 AM »

Hello!

Need some help here.

Recently, Mach3 would ignored all my limit switches and my machine would crash when it try to run past the axis limit.
The machine would run fine on some days, but on other days the problem would happen after a few hours after the machine is running.

Either one or all the M1 to M3 limit led would light up under Diagnostics screen when the problem occur.

I'm using Windows XP (SP3), Mach3 R3 043062 with Ethernet Smoothstepper.

Attached is the xml of my setup.

General Mach Discussion / Abnormal Condition, limits switches not working after trying to set Soft limits

« on: June 02, 2015, 12:00:27 PM »

Hi all,

My machine is now jogging slowly and the limit switches do not work anymore after I tried to set soft limits for it in Mach3.

This is the article I was following for setting the soft limits,http://www.instructables.com/id/Setting-Soft-Limits-for-your-Industrial-CNC-Router/.
By the way, I did not manage to set the soft limits successfully.

Also, Mach3 is now showing the Abnormal Condition message and the following is in the list of abnormalities,
-One or more axis enabled or disabled
-Exact Stop vs CV mode
-Axis are not refed to normal condition

There is 1 Meder limit switch(magnetic/electronic) on each axis of my machine.
2 stepper motors on X axis, 1 on Y and Z axis.

I have reinstalled Mach3 many times but the problem just won't go away.

I'm very new to CNC milling I would really appreciate any help to resolve this issue. Thank you in advance!!
