G-Code, CAD, and CAM discussions / Homemade table with Mach 3 torch not coming on

« on: December 17, 2020, 08:26:12 PM »

I finally got my table running.
Inkscape
Sheetcam Mach3 post processor
Hypertherm 45xp
Home made table
Mach 3 software.
Yesterday I made my first real cut but I had to start the torch manually. It will not come on automatically as it should.
It does shut itself off at the end of the run.
I do not see a M3 code at the beginning of the program as someone on plasmaspider forum suggested.

General Mach Discussion / demo version

I am having issues with my software.
At the top of the screen it says demo issue. Is that because I have not licensed it yet?

General Mach Discussion / Table size

« on: June 06, 2016, 11:50:58 AM »

I am having a beast of a time setting my table size and getting my machine coordinates to do anything. I can get the dros to zero in the work coordinates but not in the machine coordinates.
Am I right in that the machine coordinates button is showing the machine coordinates when the red led is lit around the button?
Below is my homing/limits settings.

General Mach Discussion / Plasma water table

« on: May 24, 2016, 08:15:09 PM »

I am past my electronic problems so I am starting another thread.
My plasma table is going to have a water pan and I am at the point in the build where I need to build the pan. The dimensions are roughly 5 feet by 4 foot 4 and three inches deep. I am looking for suggestions on how thick of metal to use for the pan.
forty gallon of water will be the weight.
Thanks

General Mach Discussion / homemade cnc plasma not right

« on: April 25, 2016, 09:19:17 PM »

First off this is my first build and things were going good until I tried to get the motors to turn.
Specs
Dell OptiPlex 755 computer
Longs motor kit and drivers
Mach3 downloaded
Only thing on the computer is windows7 and mach 3
I have triple checked my wiring and everything is hooked up like it should be but this is what happens when buttons are pushed.
Buttons pushed             What happens
Y+                              Y+ turns
Y-                               Y- turns
x+                             z+
X-                              z-
Z+ or-        Nothing happens
4+                      X+
4-                       X-

I have tried all kinds of pin settings and nothing changes, I have even set all pins to 0 and still get the same results.
I know it sounds crazy but that's what I have to deal with.
If anyone has had similar results PLEASE reply to this so I can get it figured out.
 Thank you very much.
