I agree with Rich and I think he sums it up well - the whole range of Chinese TB**** controllers really are nothing but trouble.

Feature Requests / Re: Laser Cutter and PPI

« on: October 13, 2017, 02:30:41 AM »

Please check out the M11P1/M10P1 commands for turning a laser ON/OFF and as Gary has mentioned the spindle 0% to 100% PWM signal can be used for controlling laser output power. M11P1/M10P1 and  PWM

Mach3 was never really designed to operate a laser so there is no actual provision to synchronize an adjustable digital output to axis velocity therefore d.p.i and p.p.i are not implemented.

However, the Mach3 Impact / Laser engraving plugin does a pretty good job of overcoming this limitation. It’s operation is considerably different to DSP systems and it takes a bit of practice to get its operation just right but, in my opinion, it is well worth the effort. Engraving.pdf    

If you skip through this thread you may find some items of interest. http://www.machsupport.com/forum/index.php/topic,12444.0.html

Hope this helps.

General Mach Discussion / Re: problems with machining holes and Z axis

Hi zxrjohn14,

Can you please attach your <profile> .xml file (the one from your Mach3 folder) then we can check all your Mach3 settings. Copy and rename the file to zxrjohn.xml before attaching using the Additional Options tab. Your profile is shown bottom right of the main Mach3 screen.

Assuming you are now using Mach3 version .062 (as suggested) then I suspect the problem is not Mach3 related but all down to your machine mechanicals, however, checking your set-up is prudent as the first step.

No problems.
My suggestion is that you download and install Mach3 version .062  ftp://anonymous:guest@ftp.machsupport.com/Mach3/Mach3Version3.043.062.exe
then we can proceed from there.

Hi zxrjohn14,

From the link you have supplied here is a quote from the machine suppliers instructions…

Friendly reminder:
The engraver will come with MACH3 software（Free Version
If you followed the intsalation tips offered by us, it works like full version.）
intsalation tips：
The software perferm better on the 32bites system computer.
Please close the firewall and antivirus software on the computer before DOWNLOAD AND install the software.(This is very important)
Otherwise, the antivirus will regards the cnc software is virus and stop the installation.
PS:Please don't update the software when installed, then it will not need the license Numbers.

If you are using your suppliers ‘hacked’ version of Mach3 then you are on your own and there is little we can do to help you on this forum.

Hi Dwa60,

That particular board is a Chinese 'knock-off' from the Planet CNC Mk1 board. Although it may work with Mach3 it was, I think, intended for use with the USBCNC software and Planet CNC claim this is not legal and condemn the use of the board.

As Craig has suggested, an ESS Smooth Stepper (or other, similar motion controller) is probably your best way forward. That way you will have a working set-up with full back-up and support.

My question is simply how: how can I do the equivalent of pressing the ZERO button with G-code?

Thought I already covered that

General Mach Discussion / Re: First startup motors not running

Hi John,

Just checked your .xml and cannot find anything really bad. Just a couple of suggestions...

Uncheck A Axis is Angular (General Config).
In Motor Tuning set Step Pulse to 2 minimum & save change.
Try changing Step Pulse to Active Low in Motor Outputs.
Try changing Enable1 to Active High in Output Signals.

Change just one item at a time and try it before changing another item - you know the fault-finding drill.

(Your Velocity and Accelerations are low but that’s OK at this stage, they can be increased later).

I am sure you are aware of this but if you are using an OS later than Win7 or 64 bit then it will never work with the LPT parallel port – you will need an external motion controller.
