General Mach Discussion / Re: Mach did again!

« on: September 30, 2010, 10:23:09 AM »

1 question,  When this last happened and MACH wondered off, did you see the wandering off in the toolpath display as well? AND did the dros show that it had wondered off the programed toolpath?

Have you tired to reload a known good backup of the XML?

IF you do not have one build a brand new XML from scratch using all the setup info that you have in your old one.

IF that does not work then do a completed reload of mach.  BUT FIRST document precisely how it happens NEXT TIME it does it

IT is important when testing that you do not jump around doing a lot of different things at the same time. ONLY a methodical test approach will find your problem. NOTES as Hood said LOTS of noted describing each step you take. AND do them them one step at a time.

You explanation is somewhat all over the place as Hood said.  Settle down and we can get to the bottom of the problem.

YOu could make a brain that monitors and compares the Y position then alters the Feedrate Override based on the % of change of the Yposition.

BUT remember it will alter the feedrate on ALL axis not just X.

Just a thought, (;-) TP

I think you should be able to just map the 2 signals as inputs directly to the thcup  and thcdown functions in config. Maybe NO code needed

General Mach Discussion / Re: G41, Strange movement, I can't figure out what dumb mistake I'm making!

YOU have alot of things going on at once(;-). YOu may want to move the G41 inside of the SUB. AS is you have the G41 in effect in G90 mode then switch to G91 mode probably confused MACH.

Notice that the the Next G1 move after your G41 is the same line you have taper. Mach needs to have a move to comp the toolpath BEFORE it gets to the start point of the offset and it needs to be at least the same length as the radius you are comping(depending on version) SO it looks like MACH is using the move to comp itself ending up as a taper???



Just some thoughts, (;-) TP

You might want to look at the  Mach  THC plugin.

IF I had a full function Machine center with toolchanger running I would look into the servo problem first. It may be a simple loose wire or bad encoder.

ITS NOT TO RUN ANY CODE IS JUST TO CONVERT A PC ON A HIGH SPEED (45KHZ) STEP GENERATOR FOR A CUSTOM MACHINE WICH USES AN STEPPER MOTOR TO MAKE ITS WORK,

** OK


ALSO IS IT POSSIBLE TO JOG ALL X,Y,Z,A,B,C AND HAVE INDEPENDENT FEED CONTROL ON EACH

** NO


 OR JUST A GENERAL FEED CONTROL FOR ALL OR THE ONES THAT YOU ACTIVATED TOGETHER FROM 1 TO 6?

** SORTA

General Mach Discussion / Re: feed hold button

« on: September 26, 2010, 12:27:42 AM »

It is NORMAL for any buffered system. Mach has to plot a solution to create an end point then safely bring the system to a halt inside of the axis tuning parameters so you do not loose position, no lost steps.

So depending on your lookahead settings it may take mach a few moves to come to a safe stop.

It is NOT a safety concern. IF you need to STOP immediately then STOP or Estop  not feedhold (;-)
