Hi Jammer,

I think one of the the commercially available 'home energy monitors' would probably be a more suitable device for your particular application. (typically, something like this perhaps  http://www.amazon.com/Weanas-Energy-Voltage-Electricity-Monitor/dp/B00DTMQ1S6/ref=sr_1_1?ie=UTF8&qid=1387628051&sr=8-1&keywords=watt+amp+meter ).

General Mach Discussion / Re: Mach3 and second parallel port card

« on: December 27, 2013, 03:04:48 AM »

When I entered the first address clicked apply Mach3 did not communicate with the card.  I then tried the second I/O address and clicked apply and this did not work either.  I then went back and input the first I/O address click apply and magically it worked.  At least until I restarted my PC and then it did not work.

Jude,

This has come up before but I cannot remember if a solution was ever found - I will do a bit of searching and see if I can find the post.

Found the post I was remembering but it's not much help - http://www.machsupport.com/forum/index.php/topic,25612.0.html

Do you mybee know how to kontrol spindle in PWM mode. if I have on PWM mode it runs on full speed. komand M5 doesentz help.

Hi Gregor,

If you return to the main page and enter    pwm spindle control    in the search box it will throw up lots of information on how it has been done.

Is it sound practice to install version Mach3 R3.043.066?

Hi Peter,

In my opinion it is best to stick with the version you are using which works unless you have some particular reason to change to a later version.

"Mach3 CNC Application has stopped working. A problem caused the program to stop working correctly. Windows will close the program and notify you if a solution is available."

This sounds very much to me as though it is a Windows / PC problem rather than a Mach3 problem. Have you made any changes to your PC setup or added / enabled any new software / hardware etc. ?

Knowing how we all like gadgets I thought you may be interested in this little device I put together last week. It is essentially a basic (and more robust) version of the commercially available ‘home energy monitor’ but it’s my hobby to always build as much of my own stuff as I can so thought I would share the experience.

Simple and quick to construct using a combined voltage / current meter display (bought via the bay from China at about £7 inc. postage) 13 Amp plug, socket and cable plus a project box enclosure.

Its purpose is just to get an idea of the combined electricity running cost of the laser, air supply, cooler, extractor etc. under average / normal operational conditions for different types of job.

The first picture shows the readings I get with my Koi air pump, cooling system and laser running at low power during an engraving job. My compressor (only used for cutting thick stuff) and ducted fume extraction system were each measured separately.

As Watts = Volts x Amps my machine, during the average engraving job, uses (237 x 1.7) 402.9 Watts which is 0.4029 kW per hour of job time. Adding to this the figures obtained from the fume extraction system and using the price per kW hour from my energy provider I can get a pretty good idea of the machine running cost (at least as far as the electricity usage is concerned).

I don’t intend for the gadget to be permanently left in circuit, although it may be handy to monitor any possible voltage drop on my supply at peak usage times, it is just used to establish the average electricity usage for different types of jobs.

The second picture shows the readings I get when cutting thin acrylic.

hi there im new to this hobby im using mach3 cnc milling and would like to cut a worm gear using 4th axis how do i go about setting this or the codes please help
Thankx

Hi Khaled,

Welcome to the forum.

Whilst machining a worm gear using a milling machine and 4th axis sounds like a simple enough task, as a beginner you may find it difficult to set up the necessary parameters within Mach3 (as explained by Al in the above post).

Not wishing to deter you from the exercise but I think that using a screw cutting lathe would be a whole lot easier.

nb. Please don't make multiple posts on the same subject, it is counter productive - thanks.

Is there a debounce timer in Mach for the inputs if it is a noise issue?

Config / Gen. Config - Input Signal Debouncing / Noise rejection.

If increasing this to say 2000 cures the problem then you may want to check your limit switches for quality / shielded wiring etc.
