Mach4 General Discussion / Re: Adding external push buttons

« on: January 23, 2016, 10:21:40 AM »

I added a manual pause button and go button to mine. There was a good post on this issue. You should be able to find it with a little looking on this forum.

That was before they got the shuttlePro plug in working. Now life is nirvana for me! Just remember the wheeles in the middle of the shuttle pro use the current jog increment as a basis for their movement. You also may have to play with the jog rate and Jog rate % to get it really working.

It was worth every penny!

See this thread for help http://www.machsupport.com/forum/index.php/topic,31367.30.html

There is also another one called "Auto Tool Zero" that might help. It talks about screensets to use as the basis.

If you mean the toolpaths. That is a problem this version has been having on my machine.

I can recommend purchasing from Bob at PMDX. They have been TERRIFIC on after purchase support.

Pedio

Note - I am not affiliated with PMDX. I just know good service when I see it!

I like Steve's suggestion if you want keyboard control. I have the Shuttle Pro as a pendant. It works GREAT!!!!!

My version remembers this setting. I have disabled it.

Mine motors over to the home switches.

Have you looked at the machine diagnostics tab to make sure that your home switches are not active; e.g., LEDs are lit.

You also have to identify what inputs your home switches are connected to in the input setup tab. I am not sure but suspect if you have not identified the input for the home switch then MACH 4 probably thinks you don't have a home switch on your system and does not move at all.

Let us know if you solve this problem.

Thanks - I have had ground problems before and I have figured out it is not an easy problem.

I will let you know how the L-Cheapo works.

Perhaps this is too much 'inside baseball' for this forum; however, I have to ask because I have #$%#@@% stuff up with bad grounds. To my defense who knew that electricity flows from the negative to the positive! They should put this in a book somewhere...     

Ok - Can I connect the grounds for my PMDX-410 together with my power supply that drives a lot of ancillary items? I have a power supply that was scavenged out of an old PC that drives fans, digital thermometer, LED light on the router, etc. It has 12V running to the router to drive the LED that illuminates the area under the router. The LED is puugged into a nice DC connector on the head. It would be easy to take the 12V connector out and plug in a connector for the laser. I could then strap the grounds of the PMDX 132 and the scavenged power supply together. This would give me my ground for the PWM connection.

If I have offended the spirits of Watt and Volt please let me know...

One day I am going to understand this enough to be able to work on an old MG.

Steve - the write up stated "Both the Mark 2 and the Mark 3 are now available with an optional PWM connector that lets you control the output via any logic-level pin, from 15% to 100% (if for some reason, such as engraving grasycale images, you need less laser power)."

Would that work with the PMDX-407 on a PMDX-410 board?

Not sure how I would get this to work with V-carve Pro yet without having to manually edit the Gcode. I did notice they have a couple of laser post processors. Perhaps one of these will work.
