General Mach Discussion / Re: Parallel cable question?

« on: September 17, 2013, 08:25:09 AM »

can anyone tell me the pinouts for the cable...the one I have is wired one to one, two to two, etc. is this right?

Gerry,

You are correct it is 1-1, 2-2 etc but check them all, just in case some are crossed or missing.

Hi Brian,

As the details on this breakout board are pretty poor (with errors) my best suggestion…

Check that your parallel cable is indeed wired Pin1 to Pin 1, Pin2 to Pin2 etc.
Check that your USB cable is providing the necessary 5 volts to the breakout board.

In Mach3 configuration (change just one thing at a time and observe the results)…
Try changing the Active Hi / Low state of the Enable signal  LPT Pin 1 (you really only need one enable signal but as you may have them all enabled then the active state of them all needs to be identical).
Try changing the Active state of the other axes (just the step pins).

That’s all I can think of trying just at the moment.

General Mach Discussion / Re: Limit switch triggered. Which axis???

« on: September 16, 2013, 02:12:28 AM »

Hi Riphet,

My view is that if it is not obvious which axis has triggered the limit switch then it could just be a false trigger. This can occur if the WatchDogs are enabled (Config / Gen Config) or if electrical noise is an issue - also mechanical vibration can activate some switches

Could you provide more details of when the limit switch triggered event occurs ?

Hi Exhausted,

Welcome to the forum.

Perhaps if you give us some details of the actual breakout board / stepper driver you are using we may be able to help you to get it sorted.

Excellent write-up and excellent work Pasquale, a feed-rate of 3500mm/min + is a great achievement indeed.

Hi Nick,

I had to chuckle at Russ's comment of robust intestinal fortitude required and he is, of course, quite right but if you want to learn LazyCam;  the manual and various tutorials are here, thanks to Rich.  http://www.machsupport.com/forum/index.php/topic,12078.0.html

I still use LazyCam on occasion, for certain types of work, and it is brilliant at what it does but it is an un-supported product and there are much better products on the market which have much superior functions. Perhaps like all things, you get what you pay for.

General Mach Discussion / Re: Does Mach 3 need dedicated PC ?

« on: September 13, 2013, 06:05:47 AM »

I agree 100% with Hood.

My view is one PC for the CAD/CAM work, internet connection etc. and another PC just for the machine.

Hi Cousinit75,

If it's any help...

Before purchasing the Vectric VCarvePro software I was getting very successful results using the free software F-Engrave http://www.scorchworks.com/Fengrave/fengrave.html - It is quite simple to use and allows allows almost all the Windows fonts to be loaded.
Final scaling adjustments of the work size can be done within Mach3 by using the Scale DRO's although some loss of character resolution may occur if the size is enlarged too much.
