General Mach Discussion / Re: The solutions to my false limit switch triggering issues

« on: April 19, 2019, 01:37:06 AM »

Hi Truckeic,

Because there are so many variables, unfortunately, there is no one solution that suits every situation.

Initially check that you have set a Debounce Interval (config. – General Config.) of at least 100 (up to 500 max.).
For your inputs (limit,home,estop,etc) they should be wired using good quality twin core shielded cable with the shield connected to a single point Earth connection at the controller end only (not chassis). Also check that you do not have any Earth loops within your machine wiring layout. If problems persist then fit 0.1uF caps. connected between each used input and GND.

Hope this helps.

Post Processors / Re: Vectric post processor for Mach 4 laser operation.

Hi Sybie,

I was using a CO2 laser for most of the tests and an impact electromagnet for some other tests.

Post Processors / Re: Vectric post processor for Mach 4 laser operation.

Hi Tweakie,

Thank you, is Auggie difficult to configure and is it compatible with diode lasers? I am using this laser from Opt Lasers https://optlasers.com/kits-and-adapters/plh3d-6w-xf-universal-kit-for-cnc-machines   

You have chosen a very nice laser with excellent documentation.

Auggie is suitable for diode laser operation but you would have to take a look and judge for yourself.
Initially, understanding something new is difficult for me but once mastered, when looking back, it all seems so simple.
If it's any help, my initial adventures with Auggie are here;  http://gearotic.com/ESW/FavIcons/index.php?topic=1785.0

Good day,

Pokeys57CNC does not support M62/M63 commands. Any idea what can be done to get the laser set-up and post processor working in Mach 4.

Perhaps contact PoLabs direct and ask them when the M62/M63 command set will be incorporated into their Mach4 plugin.

Alternately, you could do as I do and use the free software Auggie which has been specifically designed for laser use with the 57CNC. https://blog.poscope.com/auggie-cnc-machine-controller-for-pokeys/

FAQs / Re: Getting Started With Mach 3

« on: April 10, 2019, 01:49:51 AM »

Hi John,

Welcome.

There are plenty of books and manuals but a practical approach may be the best way.

Perhaps try running one or two of the sample Gcode programs from this .zip file;

https://www.machsupport.com/forum/index.php?action=dlattach;topic=18345.0;attach=47494

then step through the Gcode file (one line at a time) and observe what is happening in the display (and with the machine) and you should get a feel for what each line of Gcode actually does.

Hope this helps,

Tweakie.

Post Processors / Re: Vectric post processor for Mach 4 laser operation.

Good evening,

How do I go about using this post processor? Do I have to do any additional setting in Mach 4 or can I just install in Vectric all good to go? Please advise. Best regards.

Just copy the pp to your Vectric PostP folder then it can be selected within Vectric when creating your Gcode file.
 
This pp has been written to switch Output#1 in accordance with the M62/M63 commands – if you need to be using a different Output# then the pp can be modified by changing all M62P1 and M63P1 commands to M62Px and M63Px where x = the Output# of your choice.

Hi Wangine,

Also i will dont use DB25. TCP or USB probably. I allways hate db25 for alot of reason

I was referring to the DB25 output socket from the 57CNC v1.2.

(The output from your PC to the input to the 57CNC can be USB or Ethernet).

Why not a external PWM base timing. Exist a lot of controllers can easy pragramed with only some lines of code

It is not necessary to use a PWM controller chip, the 57CNC outputs the PWM perfectly.

Hi Wangine,

If your objective is to laser reproduce photographic images then, currently, the 57CNC and Auggie would be your best choice. As Art has said, you need to join the Gearheads forum and read all the 57CNC and Auggie set-up instructions but it is not too complicated to get everything up and working.
I used the DB25 connector from my 57CNC v1.2 and all signals are at the 5 Volt TTL level making it very simple to connect to my existing (LPT parallel port) stepper driver circuitry. As mentioned elsewhere in this thread, I manually control my maximum laser output power level and then let the software PWM vary the actual output between 0 and 100% of the level I have set. This system works well for me but experimentation is encouraged because there will always be alternative and better ways to achieve more superior results.
