General Mach Discussion / Rapid Speed Screenset

« on: July 14, 2016, 06:17:33 AM »

We have a new screenset with Mach3 and now the SHIFT key on the keyboard is not allowing rapid speeds. If I press SHIFT and arrow the machine doesn't move at all, and when only arrow key, the machine moves at slow speed...

Anyone knows what that could be?

General Mach Discussion / Insert a sequence anywhere on toolpath?

« on: July 16, 2013, 06:06:51 AM »

Hi,

Is it possible to insert a certain sequence (like our machine's plate sensing sequence - consist of 5 lines) anywhere on the toolpath?

The reason is sometimes you get a problem and plasma stops in the middle of a cut - BUT the current height is lower/higher than the start point. No you have to go back and start the last cut sequence again and let the torch run to the point where it stopped... And then the height is different and that causes errors!

I just thought it would be nice if you could start the machine right where it is with the click of a button that inserts a few lines (Plate sensing Sequence) and then continue on the path as before...

Anybody any ideas?

General Mach Discussion / Block certain lines in G-Code?

« on: July 16, 2013, 05:49:11 AM »

HI All,

Does anyone knows if it is possible to add a button on the screen that will "block out" certain lines in the currently loaded G-Code?

I want to create a button that will block certain lines that is pre-defined in a screen editor. It would be nice to have a function where I can choose a certain few lines NOT to execute when I choose.

General Mach Discussion / Z Value increases on its own - Problem

« on: March 20, 2013, 06:00:34 AM »

Hi All,

We have a problem where the Z Value (Only the DRO) suddenly moves up to the THC MAX Level - For no apparent reason...

We manufacture CNC Plasma Machines and the problem only happens now and then... We use same PC's and same software version (Version R3.043.022).

Example: Cutting a square plate 500mm x500mm
- Start to cut - no problem (THC is active)
- THC is working - manually adjust the height with our own THC module
- THC Up/DOWN lights flicker - communication is good with THC controller
- Suddenly the ZValue DRO (not the torch itself) will move up (and quick - within 1s) to Z50 (same as our THC max value) (no THC UP signal recieved...)
- Plate is deforming and torch tip comes closer to material
- Because MACH3 thinks it is already at the THC MAX value it does not move torch up and torch touches plate and Collision switch activates
 or
- if the cut is completed without crashing the torch half way, at the end of the cut the Torch crashes into the plate trying to move to [G00 Z30]... It thinks it's at 50mm above material...

Anybody have any idea about this?

General Mach Discussion / THC UP() Button?

« on: November 29, 2012, 02:18:59 AM »

Hi,

Is it possible to assign buttons on the Home Screen to move Z up/Down while cutting?

I have OxyFuel Cutter. In P&P I have activated the [Allow THC up/Down while not in THC Mode]. Then I have Assigned hotkeys for THC UP/Down under Inputs to move keys with keyboard. All of that works perfectly...

I just can't seem to get the buttons on the main screen to work. Is it possible to have hotkeys and buttons for the same function?

General Mach Discussion / Pause Mach3 with miss fire?

« on: April 24, 2012, 03:11:57 PM »

Hi,

would it be possible to pause mach3 when the plasma had a misfire? We sometimes cut a lot of holes and afterwards we would see there is a few holes missed because of misfire issues...

Any Ideas? Or is there already something like that in place?

Thanx!

General Mach Discussion / Cycle Start with an Input?

« on: November 22, 2011, 10:46:30 AM »

Hi all,

I need to start a CNC Plasma machine with an input signal...

I have to work with a contact. When the contact close it should start the cycle. Any idea how to do this easy and quick? I don't know how to use the signal on the B.o.B to actually start the program to run.

Any help would be appreciated!

Works in progress / Screenset and XML File

« on: August 26, 2011, 07:10:01 AM »

Is there anyway to change an XML file within Mach3?
I have 2 screensets - Plasma & Oxy - that works on one machine - 2 heads. I want to setup my Machine with Auto Mach3 Start up. I don't want the operator to have to exit mach3 for any reason. This means I want to start the machine and the operator only log in and Mach3 comes up. I have done everything (and its working) to change the screensets. Now...is it possible to change the XML file with screenset? Any way at all? Or otherway around - change XML file within Mach3 that automatically change the screenset?

Any help would be usefull!

General Mach Discussion / G68 and Plasma cutting - help!

« on: July 13, 2011, 05:03:05 PM »

Hi all,

I can't seem to find anything on XY rotation for a CNC Plasma Cutter.

I know other controller software can do it, so MACH3 should also be able to do it! When we load a plate on our bed it is not always 100% parallel to the X or Y axis. I want to use a laser (with an offset to the torch tip) to calculate the amount of degrees that the plate is rotated. I figured it to be something like this:
1. Move torch to corner of plate (which should become X0, Y0)
2. Laser shines on the corner and operator press button to say this is the 0,0 coordinate
3. Operator moves torch along the X axis towards the next corner (which might be at an angle of say 5°)
4. Bring laser to exact corner and operator press the button again to tel the machine the current coordinate. (ex X1000, Y20)
5. Now (somehow??) it should know the plate is not parallel to the side and rotate the XY plane by 5°

After the job is cut it should take the XY axis back to normal state.

My research only told me that it might be the G68 code, but I have no idea how to use it! This would save a lot of time in CNC Plasma Cutting!

Any help would be appreciated!

VB and the development of wizards / Oxy Fuel Safety timer

« on: June 30, 2011, 02:09:46 AM »

Hi all,
I am setting up Mach3 to run with a Oxy Fuel process. I have searched everywhere but can't seem to find any info.

I want to put a simple safety feature in place that cuts off the gas supply if auto ignition haven't been confirmed by the operator within a certain time frame. Since I don't know too much about VB it is a bit difficult... I have read through a lot of posts but I still can't get something. The basic process would be something like this:

Timer countdown 25s (a visible counter would be best)
If "operator have confirmed ignition before " then "resume cycle"
else
STOP

or maybe on different approach:

Timer countdown 25s (a visible counter would be best)
if counter = 0 and confirm = 0 then stop

if counter >= 0 and confirm = 1 then Resume

Any help would be much appreciated.... I've spend many hours trying to work it out but to no avail.
