Odd pause in motion...
Been cutting a bit today and some of the parts had many 12mm holes in them, I always try and keep the lead-in to the centre so had a 6mm perpendicular one programmed.
When the cut starts, the IHS is done ok then the torch drops to cut height and runs the lead-in but when it reaches the perimeter there is a clear and definite pause in motion, not seconds but very noticeable.
G-code shows a G03 in use here.
On a shape cut, i still use a 5-6mm perpendicular lead-in but the is no delay at all - it just runs from lead-in to cut as expected.
G-coed shows G01 in use.
Is there a reason for this or something i can check as its not doing my divots any good at all

Re: Odd pause in motion...
Have you tried using an "arc" lead in, instead of perpendicular? May give you a smoother transition.

Re: Odd pause in motion...
Not specifically, only noticed this yesterday, only does it with circles not lines and shapes??

Re: Odd pause in motion...
Are you using any sheetcam rules?
I can get that pause but not on inside circles it's usually on a outside cut if I use perpendicular lead in.

Re: Odd pause in motion...
Hi
yes there would have been a 60% reduction in speed in force but thats all really.
I use perpendicular on all jobs but it only does the delay on holes??

Does it disappear if you turn off thc?
This is what I use on holes less than 35mm dia

Re: Odd pause in motion...
Thats pretty much identical to my setting, thanks
I will have a go with THC off next time i'm running.

Re: Odd pause in motion...
That causes a pause in mine.. I kind of thought it might be a SheetCam issue? I just stopped using it, and just use the other two lead-in styles..(for now anyway)tnbndr wrote:Have you tried using an "arc" lead in, instead of perpendicular? May give you a smoother transition.
Mine is the 3100 series THC..

Re: Odd pause in motion...
Cant see how it can be sheetcam, my money is on Mach3 or THC possibly. The G-code created by sheet cam looks ok.

Re: Odd pause in motion...
I had a similar issue when I uploaded the tool files from CandCNC, turned out to be the THC ON/OFF command in the g-code was pausing my machine.

Re: Odd pause in motion...
Yes
I have Les over at Sheetcam looking at that now, I have a double S10 code entry where it should not be, that is the suspect at present.
I have narrowed it down to where sheetcam auto detects outside or inside cuts -
Job has outside cut only = code ok
Job has inside cut only = job ok
Job has outer and inner cuts, sheetcam set for outside and auto detects the inside = duplicate entries.

I have had SheetCam for about 12 years, and always check with Les on funny things happening like that.. You tend to get it resolved one way or another..davek0974 wrote:Cant see how it can be sheetcam, my money is on Mach3 or THC possibly. The G-code created by sheet cam looks ok.
