PoKeys / Re: M code Pauses Machine while running G-code

NOPE that wont work you only have 1 set of pins to trigger whatever you do. AS soon as you add in a macro code to detect or manipulate the signal you get ? YEP the delay.

What you need to work with is the brains they have a higher prioirty and better access to the internals of mach3. Now can you make them do what YOU need

Good Question, (;-0 TP

General Mach Discussion / Re: G52....

HIYA RAY, I looked further sense we last talked about it. As it seems in MACH the 52 and 92 share internal mechanisms AND the G52 command shows up in the diagnostics as a G92 offsets SO I would guess in MACH3 they are bascially ONE in the same. I am GUESSING HERE so it is NOT the gospel.

I do know the the G52 causes the SAME Problems with subs and toolcomp as the G92 does so

Let us know what you find(;-) TP

I would venture a GUESS that somewhere the PC  or MACH3 is throwing an error ( THE BEEP) and is causing a problem for mach3 after that.

when it happens LOOK for an error message, Even window DOWN mach3 and see IF there is one behind the Machscreen.

THE BEEP is a clue.

Sounds like you have metric and imperial modes mixed up somewhere.

And you are not making it any better for yourself are you??

Welcome aboard Formtool. I see you have the link to the Manual. You have to remember this a "backpage" that is seldom travelled and it may take a while before anyone notices you.

IF you have an important question and NEED a fast responce start at the MAIN page. IF it ends up being minor they can move in BACK to here BUT you will be seen (;-) and responded too.

SOme people just heap coals on their head and can't figure out WHY it keeps burning their head.

(;-) Now you have entered the CATCH22 zone. Big motors ,Big Hurry , BIG drives  BIGGER price tag.

yOu can LOOK aroound BUT you have to be REAL carefully of what you buy for the older DC motors. You may require step/dir control and most older drives for the BIG motors were analog. AND you never know how old or used the used ones can be.

The ac drives (step/Direction)I use here NEW are about $800 each. The Mazaks here are $1800 ea refurbished.

AN option may be to replace the "motors" with something MORE compatible to the lower end drives you have.  That and a little gearing MAY solve your problem and allow you a lower cost replacement IF you loose a drive along the way.

Just a thought, (;-) TP

General Mach Discussion / Re: Using rg-59 TV cable for home and limit switch(s)

« on: October 11, 2011, 03:47:33 PM »

YOU end up with a LOT of rigid cable hanging around your machine. For each switch you still have to have wires going to the switch and away from switch. IF you daisey chain them it makes it worse sometimes. AND the wire is normally rigid core easier to have break due to vibration and flexing.

BUT if that is all you have access to better than nothing(;-)

General Mach Discussion / Re: homed axis (XYZ) DRO does not read zero

« on: October 11, 2011, 02:41:02 PM »

DO you have the auto zero checked for homing or are you using a home offset value OR are you using the set values for G28?

If you look in the Mach3screen reference manual on page 23 it shows the options you can choose to use to setup the home positions. There are many(;-)

Just a thought,(;-) TP

DOn't let them fool you yes ballscrews can be rebuilt/refitted with oversize balls. Chances are someone loaded up the nut with an ODD combination of ball diameters and it bound up the screw. DO a little research. You just have to be patience and measure ALL the balls and then ADD and subtract as needed .
