General Mach Discussion / Re: Work Offset Parameter Values?
« on: September 05, 2010, 09:49:09 PM »
It is a error in the book . If you notice where the descriptor "Workoffset values" is it spills over to the next line and it OFFSET the numbers by one line. It was never corrected.
I have a list somewhere BUT it is a VERY VERY long list.

I don't think you will see a difference UNTIL you run code. That is when it should blend the feedrates.

Just a thought, (;-) TP

General Mach Discussion / Re: Zeroing machine coordinates
« on: August 23, 2010, 01:27:31 PM »
The way I do with manual tool changes is touch off to the TOM(top of material) then set z zero. Now touch off on another spot on either the actual fixture if used OR the table top or some other permant spot. Then write down the number.

Then at next tool change change tool and touch off on the reference point and set the Z to the saved number.

BUT to each his own(;-) what ever works for you.

The machine coords are just that coords for the machine to use to keep track of where it is at in 3d space. They are not there for you to use on a daily basis. and that is WHY you cannot zero them as you think you should(;-)

The user coorrds are what you use to do work.  Set up your machine and touch off Z zero it.   Then whatever you do after that tool wise that you simply change tool ,touch off rezero the z and you are done machine away.

You don't base tool height offsets from Machine coords Z0.000 you use the Coords base you are in at the time for example G54 or G56 or G55.

YOu might want to consider getting a good primer on cnc and gcode to get a good understanding about offsets and how they are used in CNC. It will save you a lot of hair pulling

Just a thought, (;-) TP

You should be working in user coordinates not machine coordinates. Sounds like you are in machine coordinates if the zero axis button does not work.

Just a thought,(;-)

CLOSE enough(;-)



 It is probably best to just leave it at a custom thing and not a general Mcode function unless Brian can add it to all the drill cycles

HIYA Scott, If you have not figured it out yet we are CLAMPING the gantry to the bed from  INSIDE of a canned drill cycle(;-) so obviously it cannot clamp while XY are moving.

 From my perspective it would need to clamp as soon as the Z started to move down to secure the gantry before the bit gets to 0.000. or else the gantry can jitter if the bit gets to the material before the gantry gets clamped tight

On the Z up stroke it needs to wait until after 0.00 is reached before it unclamps to insure the bit does not wobble in the hole AND give the unclamp cycle time to unclamp before the z reaches the Rlevel and the xy starts to move to the next hole. If the clamp does not unclamp fast enough OR you do not allow enough time based on teh retract level the xy drives may fault or steppers loose steps.

My thoughts are instead of a preset height "trigger" the clamping would begin on the start of the downstroke and end after it clears 0.00 on the way up. That way the operator/programmer can adjust the clearance height needed to allow cycle time for the clamp to work via the retract level of the Drill cycle and could be set from the Cam post.

Also remember some drill cycles are not like the G81 where you have a straight move to the bottom and a straight move to the top again. The g83 is a peck cycle and there are dwell drill cycles as well so if that can be worked in it would be great

This could be a very handy MACH  Mcode utility.

Just a thought

The autosaved versions are only reloadable from inside of mach. They have a differrent extension.  The original backup will be named exactly like the one being used only stored in a different directory.

AS a rule you should keep a backup copy of the XML stored away somewhere safe (off of the computer) just in case you need it

So far about 99% of the time I see strange things showing up in the dros it points back to a corrupt XML. Not saying that is YOUR problem but I would check it to be sure.

Just a thought, (;-)

Hiya Scott, I think the idea was to have the clamp set as the z starts to move down(before0.000) and release after the z clears 0.000 going up to the top again. I was working on a brain to sense Zdirection but could not get it perfected, close but not perfect.

IF you want to try something try reloading a backup XML, not the autosave version but an original copy.
