General Mach Discussion / Re: Mach3 Torch Height Control

« Last post by gordond on May 25, 2024, 11:29:27 AM »

Yes, my Mach3 is licensed. But you didn't address my question:
Would the hardwired THC On signal being asserted before the Torch On signal is produced for piercing be preventing the THC from working?

Make sure that Mach3 is properly licensed and that THC is enabled.  You should be able to see THC action in test mode.

Modbus / Sound Logic Spindle Speed Controller

« Last post by Scott on May 25, 2024, 02:12:54 AM »

Hello,

It's been ages since I've been in this neck of the interweb!    I'm looking for any possible information on a SoundLogic S-Spindle Speed-R3 Rev4 board.  I'm pretty sure it's a James Cullins design.  I've never had the pleasure of messing with what I'm assuming is a Modbus/serial setup, so any info would be helpful and appreciated. 

Thanks,
Scott

General Mach Discussion / help woth converting mach4 macro to mach3

« Last post by bogaskilop on May 24, 2024, 05:51:27 PM »

Hi all

I really need help with converting one macro from mach4 to mach3 for my machine as the manufacturer of my CNC  doesn't provide same macro for mach3 , ArtSoft also doesnt want to help, witch is a bit strange as they still selling mach3  .

it's a macro to set B/C head and measure tool length from tip of the tool to specific place on B/C head and that is a tool length for Fusion360 postprocessor also.

Is there any one with knowledge  of VB mach3  and Luna mach4  and can help me with that.

thx for any help.

General Mach Discussion / Mach3 Torch Height Control

« Last post by gordond on May 24, 2024, 12:08:23 PM »

I have Mach3 running a plasma table with a floating head mounted torch. The system works fine.
   I am in the process of adding a DIY THC and doing some testing. Since I'm doing the testing with the torch off, an external supply is providing the torch voltage signal to my THC unit. My THC has been bench tested and appears to be correctly wired into Mach 3 and working in that I can see the Torch UP and Torch DOWN leds operate on the diagnostics screen as the simulated plasma voltage changes. Since the torch is off for testing, the THC On signal is hardwired to ground (active low) and the led for THC On lights in the diagnostic screen. I've examined various videos re getting Mach3 set up for THC and I think I've done what's required. However when I run a simple tool path, even though the UP/DOWN leds change as the simulated plasma voltage changes, I get no response on the Z axis.
   Would the hardwired THC On signal being asserted before the Torch On signal is produced for piercing be preventing the THC from working?

General Mach Discussion / Re: windows 10 running Mach3

« Last post by arturod on May 24, 2024, 07:14:23 AM »

Most of the cheap USB motion controllers do not handle discrete signals in real time, so features that need this, like homing, probing, THC, never really work well.  The ESS and CNC Drive stuff is good, but CNC Drive has not been updating the Plugins, so you may need to run older versions of Mach4.

G-Code, CAD, and CAM discussions / Re: Mach3 Minimum Step Length?

« Last post by Graham Waterworth on May 24, 2024, 06:13:11 AM »

Mach3 works to 8 decimal places, most code only works to 4.

I ran your code in fresh air and it worked fine on my machine.

In my opinion Mach4 would be a better option and yes, you will need an EMC. There are many different EMC's available and it is best to choose one of EU or USA manufacture as these work correctly and have manufacturers support (unlike those cheap versions from China).
My preference for EMC is either the Warp9TD ESS or the CncDrive AXBBE (I use both, on different machines).

morning to you gentle men who answered my post.
Apparently, windows ten doesn't use a parrel port or so I see on many utube programs.
Tweakie, I have no clue if it's a @bitsensor@ board but it does connect by usb.
JohnHaine, I'm looking into suitable EMT
Thank muchly u guys.
Another question would mach 4 be a better option and does it need a EMT and of what sort

cheers Rossco

G-Code, CAD, and CAM discussions / Mach3 Minimum Step Length?

« Last post by Holzwurm56 on May 23, 2024, 07:48:21 AM »

Hello,
could it be that Mach3 doesn't execute steps below a minimum length? I have a file here where the lathe stops at line 154. Can this minimum length be set somewhere?
Thanks
Hans
