General Mach Discussion / Re: Work offsets

« on: September 17, 2011, 08:50:21 PM »

HIYA Riley, I think I can save you some more time (;-). I came up with a workaround that will allow you to do as you wish roam in the Workoffsets as you please.

DO NOT USE G54 as your base offset.      Use G55 and above as your base offset X0Y0 THEN you can program as you wish it will work 24/7. JUST DO NOT USE G54 anywhere(;-)

I think I have the BUG narrowed down to just a small window of possiblities now.

Give it a try, Let me know IF it works for you. (;-) TP

RAY, the darkside cured it.  Sorry I can't be of more help on that one. I gave up long ago on getting it fixed.

RIley I have developed a WORKAROUND for you that makes sense. We have to get creative and shift the Fixture offset BEFORE you leave the sub. Then it will work every time. The only limit IS you have to make sure all the fixture calls are in the same order of progression as the #var formula to index up the number. NOte that it starts with G54 then each loop indexes the G54 UP 1 number G54,G55,G56,etc. IT will not allow you to randomly switch Fixtures but at least it does give you an Option with TC and fixtures.

I have narrowed this problem down to a very specific area in MACH3 that should not be hard to find(;-).

There IS one other way that is not as messy. It keeps the Mach coord base intact so you at least know where you are(maybe). It also works EVERY time. IF you set the Work 0,0 as refhome(machine 0,0) then it it is fairly simple.

G54
M98 P1 L1
G0 X6.000
M80  ( zeroX, zeroY  )
M98 P2 L1
G0 X6.000
M80
M98 P3 L1
G53 X0.000
M80
M30

HOPE it helps,(;-) TP

NOPE it does not work here, same thing.

I can do what you wanted but it is not a pretty thing to do. Instead of using a Fixture offset, G92 or G52 You can use a G53 move in machine coords then use a macro to reset machine Zero. That process works EVERY time correctly. Trouble is YOU Have to keep track of where you are instead of MACH doing the hard work(;-)

I have found it broken on W2k XP and Vista so far. Have not tried it on Win7 yet.

Please list the code you were using.  Also include what the modal calls were in the mode list.

yep you are correct. I was remembering that Art had said there was a situation that caused Mach to exceed the max vel on a combined move. I'll have to do some rerearch now(;-)

You have the velocity set too high for the motors/drives you are running.  When the machine makes a diagonal move the actual motor speed has to be a lot higher than the commanded rate to create the  commanded feedrate.

As a test lower your motor vel setting in config by half then retest. If that works keep bumping UP the vel until you find the sweetspot.

Just a thought, (;-)TP
