General Mach Discussion / Odd glitch in movement?

« on: April 24, 2014, 07:16:54 AM »

I drew up a part this morning and run it on my plasma table in thin sheet as a trial part.

It contains arcs and straight lines plus one circle, I have attached the dxf file plus a picture.

On the picture I have marked four points where the action goes from straight motion to an arc and there is a visible divot at each point.
However there is no divot at the exit from each arc - it transitions perfectly. The other bigger arrows indicate cut direction.

I can not see anything wrong in the dxf and likewise in sheetcam so it has me guessing now, any ideas???

ALL ISSUES FIXED!


For some reason there is a tick box in general config "Perform G92.1" for end of job options, this was ticked, unticking it solved the issue

Should be good to go now

Thanks all.

If you take the M30 line off the file it all runs perfectly, leaving the Z DRO at 5mm

Then Type in M30 in the MDI box and it puts the machine co-ord for Z into the work DRO


Why??

Ok, tested it and yes it all works ok on a cut, the only odd bit is at the end when it puts the machine coordinate reading into the work DRO??

However, since changing to G28.1 when the post code reaches a goto-rapid-clearance height, the Z motor emits a loud screech and does not move, I cant see a reason in the code attached, can anyone have a look, I'll also bounce this one over to the sheetcam forum.

You were right, sort of

As this was a repeat test block, I put an M30 rewind at the end so it just probes then rewinds.

The G28.1 block works perfectly, however when it hits the M30 it jumps back to the start and then copies the machine co-ord back into the Z DRO this is where it was getting its random number.

Is there a reason it would act like this, I thought M30 just looped back to the start of the G-code??

When it's run, z is at no known state as I have removed it from home all, it will only be homed once metal is on the table ready to cut. It homes downwards now.

In config, I have also ticked " g28 no intiial move" to stop the upwards motion first.

Single steps or entering it one line at a time in MDI works perfectly, I typed it into a .tap file and although it worked, it left the DRO at an odd value

Does the DRO track the correct position too??

Mine did not.
