FAQs / Re: +1mm -.99mm?

« on: March 15, 2017, 09:40:38 AM »

Hi Mick,

I can’t find anything in your .xml settings file to cause the problem.

Couple of things though…
In Config. / General Config.  -  set a debounce interval of 100 and uncheck Use Watchdogs.
In Config. / Motor Tuning – try setting Step Pulse and Dir Pulse to 2 and save the changes.

I am pleased to hear that you have got it sorted. 

Don't forget to post some pictires of the things that you make with your new CNC, we all love to see pictures.

Hi Mick,

There are some known problems with version .066 so it may be best if you installed version R3.043.062. Make a secure back-up copy of your existing Mach3 folder then install version .062 over the top of your existing installation. Version .062 can be downloaded from ftp://anonymous:guest@ftp.machsupport.com/Mach3/Mach3Version3.043.062.exe

In the meantime I will check out your .xml settings and see if I can spot any problems.

Yes sir, axis directions should be set-up first but remember it is the tool direction relative to the work that counts rather than the actual direction of axis movement. If that makes sense.

This right hand rule diagram shows the direction the cutting tool should move in relation to the work piece.

If your keyboard keys move an axis and the DRO's in the wrong direction then that can be changed in Config. / Ports & Pins / Motor Outputs by changing the Direction Low Active state.
If your keyboard keys move an axis in the wrong direction but the DRO's are correct then that can be changed in Config. / System Hotkeys.

Once you have that working correctly then set-up your limits and ref.

Hope this helps.

General Mach Discussion / Re: Mach3 on a laser cutter...

« on: March 14, 2017, 05:41:48 AM »

Looks like more fun then Dave. 

Is it fast enough?

Depends on the maximum axis speed of your laser cutter but I would say Yes Mach3 is fast enough.

Does it do PWM power control?

Yes, using the S### command

Is it better than the built-in controllers found on eBay laser cutters?

That is a matter of opinion - I would not say Mach3 is better but I think I have managed to do anything that the built-in controllers can do.

Anyone running a 50-60W laser on Mach3?

Unknown, my laser is only 40 Watts.

Hi Mick,

Which version of Mach3 are you using ?

Can you please attach your .xml file. The one from your Mach3 folder called <your profile>.xml
You need to copy it then rename the copy to mick1.xml then use the Reply tab and Additional Options to attach.

Hi Si,

Welcome to the forum.

In Config. / General Config. try entering a figure of 500 in Debounce Interval. It would also be good to uncheck 'Use WatchDogs'.

This should stop the unwanted Emergency Stop situation.

Hi Mick,

Welcome to the forum.

Could it be that you are loosing steps ?

Try reducing your Velocity and Acceleration settings (in Motor Tuning) by 50%, saving the changes, and see if the problem persists.

What happen if you cycle longer movements (say 100mm) ?

Check out F-Engrave. It is free and the video on inlay describes the type of engraving you are describing http://www.scorchworks.com/Fengrave/fengrave.html
