General Mach Discussion / Re: CNC MISSING THE ODD STEP

« on: August 05, 2011, 02:37:41 AM »

Hi Jim,

Two things you could try;

Try selecting 'Sherline 1/2 Pulse Mode' in Config / Ports and Pins.
Try increasing the Debounce Interval in Config / General Config.

Your Kernel Speed should really be set to 25000Hz or 35000Hz.
The TB6560 is a good chip (assuming it is a genuine Toshiba and not a clone) so that Chinese board should be OK.

General Mach Discussion / Re: mach3 estop external switch issue

Going off topic and reverting to the fingers issue;

I have friends in the woodworking industry who have missing parts of fingers. It is perhaps surprising but they were not lost through lack of experience (one had 40 years in the trade) they were lost through complacency and familiarity with the machines they used and they will all say that they have no one to blame except themselves.

Take care Guys - It is not luck that keeps fingers it is vigilance.

General Mach Discussion / Re: Caps on inputs

« on: August 04, 2011, 12:52:40 PM »

Well, we switched the caps to go from the input pins to ground and the test pattern worked perfect!! but...then a longer pattern flipped out. We definitely have interference issues. Gonna rewire with shielded cable - is this stuff any good or is there some that would be better? http://homeavcables.com/22108.html

You would be better using a cable which has a braided shield (more surface area) the foil stuff is OK but far from Ideal.

Tangent Corner / Interesting 2 ?

This looks like an easy way to interface an "add-on, high speed engraving spindle". (as featured in Digital Machinist)  http://www.logicnc.com/rcnc.html

Hi Jas,

I understand what you are trying to achieve but safety must always take priority and as Terry has already said this is a dangerous way to go.

Far greater minds than ours have decided this is the way it will be and for good reason and what you are attempting could perhaps be considered as the equivalent to defeating a safety switch or machine interlock.

We must all pay strict attention to safety if we are to "live to machine another day"

I wish if a day was mach's day in a year, when all the cnc jerks could enjoy some beer together somewhere (some could have scotch also)

The Beer would suit me just fine
