General Mach Discussion / Re: CNC router shudder and jerky / jitter doing 3D toolpaths

« on: February 06, 2016, 04:50:52 PM »

In this case teh User was using a Fanuc post cause Fanuc uses teh G8 P0 and P1 to turn off/on exact stop.

And someone is getting very Quick with Mach3 searches (;-) Old QuickSearch McGraw

I also have a copy of ALL teh old Yahoo Messages even from teh Master5 days. There are MANYMANY thousands of pages of messages from that era of Mach3  Art did a LOT of explaining back then and it is ALL in teh archives.  Another late night best reader (;-).  Art is quite teh story teller (;-)

I would do the same for this site but don't have a clue as to how to get them all.

One day they are going to disappear and it would be a shame NOT to have a copy.  

NOW you know, (;-) TP

Repeats (;-) and YES it all works HERE including the M901 Mcode.

G0 G17 G40 G49 G80 G90
G91 (Set Inc Mode)
G0 X0 Y0
F600
M98 P001 L22 (Loop 22 times)
G0 X0 Y0
G90  ( Reset Abs Mode)
M30

AH GEE Do I gotta give up teh magic monkey dust again 

In mach3 G8 and G9 are the same as G61 G64.

In Mach4 G9 changes to a one time Exact stop move and I hope that G8 is not there any more.

now for the next lesson when it is late at night and you can't sleep simply bring up teh MDI line and start from G0 and keep going up till you reach G1000. IF you see it does not error (;-) then it must do something, THEN you figure out exactly what it does do (;-) You MAY find some things that carried over from teh original EMC code.

Same with #vars (;-)  I created a serach program in CB that prowled all teh Variables up to 30,000 to see what might show up. Then compared the OLD EMC code with Mach3s code references to see what might be lurking there.

Same with Mach3's CB editor. You would be surprised what works based on Visal Basic calls  and is NOT in teh Mach3 CB manual.

Repeats are easy BUT teh Mcode has to work correctly first (;-)

Motion error would be a possible setup problem with your steps per. Either they are not correct OR leaves the step motion so course as it cannot make the correct motion based on full steps. 

For example IF your setting gives you a Min move per step as say .003 and you tried to move .008 as an inc move then it will stop short at .006 rather than overrun to .009.

Are your DROs displaying the correct values for each move ??

Spaces have nothing to do with anything in Mach3 Scripting.

If that does not work then it is 1 of 2 things Your signal is not being seen OR the logic expression for the signal is wrong.  

Do you see the Input1 signal activate on the diagnostic screen when teh driller is done ??

IF you noticed on the first line it did include teh G64 (CVmode) BUT it then turned it off with G8 (exact Stop)

BPs makes ok conversions if you already have one,  There are good Zquil designed drives  OR just lift the Knee instead of the Quill. 

Just a thought, (;-) TP
