Mach3 and returning to cut position
Hi guys
Hoping someone can point my in the right direction with this.
Is there a setting in mach3 that stops the z plunging back to cut depth before it gets back to x and y cords?
So I paused my machine because I wanted to clear a block on the dust shoe. Moved the spindle to the corner of the bed cleared the block then roughly returned it back to where I paused the cut. It then started to move and plunge resulting in a Grove cut towards the hole it was cutting. See pic
Hope that makes sense. https://uploads.tapatalk-cdn.com/201...21e23ec5c7.jpg

Works fine for me, what version are you running?
Re: Mach3 and returning to cut position
I think you have to reposition the Gcode so that the first move is to the safe height. Not being in front of my machine to check it out. If I am not far through a job and I have to stop it, I just rewind and start from the beginning, just cutting air until I catch up. I may even override the feed rate until I am near the cutting point. But that is just me taking the easy way out.
Re: Mach3 and returning to cut position
I've never had much luck with the "pause and resume" thing in Mach. It tends to do sporadic and sometimes unpredictable resumes. So now I no longer use it, and do the same as the guy above.
All the best,
Dan

What version are you using?
Version R3.043.062 is one of the last good, stable versions before The Incompetent New Guys started buggering about with Mach3, creating more problems than they solved in the process.
Re: Mach3 and returning to cut position
Shouldn't you be using Run From Here, to resume after jogging away from the pause point?
Pause and resume will do what it says. Resume motion from wherever you've jogged to, even if that means ploughing straight through the work piece to get to the next coordinate, whereas Run From Here should do an initial move then plunge to the resume point, which you should be asked the details of to confirm the initial move is suitable.

The man who conceived, created and maintained Mach3 sold the company to a bunch of utter Muppets, unless you need support for a plugin that's only in a later version the consensus from far more experienced users than I is don't touch them with a long stick.

I do exactly the same, been caught out with ruined work pieces too many times.
