General Mach Discussion / Is this possible?
« on: February 28, 2016, 08:04:24 PM »
I am trying to convert an old Amada NC ironworker over to newer controls.   My old controller died a few years ago, but I was able to get it repaired.   It died again, and the company that repaired it has gone out of business.

For the most part the controller is simple.   The hydraulic pump, and a cylinder that goes up and down, a turntable, and the NC locator that moves back and forth.

Is it possible to have a Mach screen that I can enter a length--- say 4 inches, then have the locator move 4 inches, the ironworker punches, then repeat ********* number of times?

What type of controller do I need?   


Thanks

General Mach Discussion / Mach 3 starts on its own
« on: June 29, 2015, 01:42:30 PM »
I turned on my flame table today, powered everything up, and pressed the red RESET button and the Y axis started to move on its own.   I have not made any changes, or added any updates.

I am using Toms CandCNC BOB, and it has a LED for each axis and it flashes when Mach3 tells the axis to move.   This LED for the Y axis is flashing, so Mach is telling the axis to move.


any idea where to start?

General Mach Discussion / New lathe idea.
« on: April 02, 2014, 04:54:37 PM »
Hi all

I bought a non working Mazak qt 15 lathe.   I was told it is a minor problem, but so far it is still broke.

I know it should be fairly easy (not cheap) to switch it over to Mach.   I have a Mach flame and plasma now, working on a mill also.

So here is my question-

Do you think it is possible to add "live tooling "to the lathe if I convert it to  Mach

General Mach Discussion / Problem with Mach3
« on: October 07, 2013, 07:50:04 PM »
I have been having problems with my set up for several months. 

When I open Mach and start the program, I have to go into the ports and pins configuration page and change the address for the second LPT port.

I just change the last number to anything.  Then save the settings.   Close the page.   Reopen the page.  Change the address back to the original address.  Save it again

and guess what everything works!!.   If I don't do the above steps, everything connected to the port 2 does not work.

I usually just leave the computer running, but sometimes it gets powered off.

I upgraded to the latest release.   Did not help.


any ideas where to start?

dspMC/IP Motion Controller / Can the DSPMC/ip do what I need?
« on: October 05, 2013, 06:27:07 PM »
I posted a question similar to this one on the general tab, but so far no responses.


Here it goes

I have an Amada NC iron worker.   It has a six station turret that rotates.   I can punch, shear, notch and bend. It also has a x axis positioner.   This is a very handy machine, and the CPU has died.

Since it is twenty years old, and a Japan only machine- Amada is really no help.   I removed the CPU and shipped it to NC last week to a place that said they should be able to fix it.  I am not counting on it.


So I am planning on the worst.   If it comes down to it, I need to have a list of parts that I can order, and install  as soon as possible.


From what I can tell, I need a simple way to input the length for the positioner to move, and how many times to repeat.

It also has several limit switches and a few buttons.   

The turret only uses a motor contacter to turn the table.

The only thing I am not sure of is how the pressure is controlled for the bend function.   There is a large know that I turn to adjust the amount of force.  Not to sure if it is strictly hydraulic, or electrical and hydraulic.

so I am planning on it being electrical controlling the hydraulic.   It should be 0-10 vdc for the input and 0-10 vdc for the pressure valve.   


any ideas?


I will add a picture of the user interface in a few minutes.


thanks

General Mach Discussion / Need help--or ideas
« on: October 04, 2013, 02:03:44 PM »
Hi all-

I have a nc Amada iron worker that looks like the CPU is bad.    I shipped the CPU to a circuit board repair company in Charlotte NC earlier today.

Now I am looking for options incase the CPU is not fixable.

The iron worker is a simple design.   It has a hydraulic pump and cylinder, several switches, and a x axis stepper motor, and gear rack.


All I have to do is to set the required length, the pitch (number of offsets) and then press the run button.
Once the run button is pressed, the x axis backstop moves to the correct position, I press a foot pedal and the ram presses, then the x axis moves to the next position.   Then everything repeats.


There is also a turntable that rotates to different dies.   But this is a simple motor contactor.

Any ideas on where to start?

I have built a CNC flame cutter, so I am not new to this.   Just need advice.    I need this for my business.

General Mach Discussion / Flame cutter won't jog.
« on: May 19, 2013, 04:27:02 PM »
My flame cutter has been working great for the last year.   I have not done anything to it besides use it.   It is not connected to the Internet, and I have not upgraded either Mach or sheetcam in a year or so.

Yesterday I powered everything up, and tried to jog the cutter.   It will not move in high speed.

I reset the DROs and moved the head.  According a tape measure it is moving the correct distance.

Where should I start looking?


Thanks

General Mach Discussion / Linking three programs
« on: February 08, 2013, 11:32:20 PM »
I am needing help figuring something out.   I have several thousand pieces of 4 x 4 x 1/4 square tube that I need to notch on three sides.

How can I right / link three separate programs together so that the first program runs completely, then stops at a wait point.   I then manually rotate the tub in a jig.   Press an aux. start button and program #2 runs.   Then #3.

After the third program runs the flame cutter goes home and starts over with program #1 on the next start button push.



Thanks

General Mach Discussion / External start button
« on: July 06, 2012, 08:42:37 PM »
I finally have my flame table running halfway decent, so it is time to start monkeying with it.   I am trying to add an external start button.   I have a switch wired up already, and it works.   I have it assigned to turn on an input #1 so I can watch the led turn on and off.

The problem is when I try to enter a number "1000" in the ports and pins for OEM trigger #1 .   I can't enter a number, it will only allow me to press a key and then the number is automatically entered.

What am I doing wrong?


Thanks for the help

General Mach Discussion / 4 to 20 ma
« on: June 03, 2012, 05:13:59 PM »
I am working on a idea that I need help with.   I tried the search, but nothing showed up.

Is there any way to get mach to output between 4 and 20 ma that I can control?
