"run from here"
« on: January 22, 2011, 10:16:16 AM »
hey gang
Need some help.........
I have this program, an airfoil outline with some spar cut-outs.
It runs very smooth along the arc until I use the "run from here" option.
After that.........the arc is cut in jerky small steps. Nothing I can do changes this. Even ending out of Mach3 and reloading the G code , nothing helps. Its jerky steps from then on.
Someone help me here!!!

Why are you using run from here?  Are you having to stop the program for some reason and restart it in the middle of a run?

Sometimes I get a similar problem.

Mach drops out of CV (G64) and into exact stop.
Make sure you have  G64 at the start of your gcode to tell mach you want to run in Constant Velocity.

Might be totally unrelated but maybe worth a go ?

Some of the "pros" now tell me to NOT run from the USB stick.
Random ********* will happen............so they say.
All good advise................thanks for answering

The problem is the drill cycles SOME  drop OUT of CV to do the cycle and does not reinstate it when done, Especially when using the RFH.  I notice that you dont have a preamble to set all the gobal values (;-) such as G64,etc.

Also a good idea to set them after any canned cycle.

Ah OK running from network or USB is not a good idea, if you had said that it would have been the first response from most here ;) It is always best to have the file you are running on the hard drive of the computer you are using.

Regards the xml, it is the configuration settings you have done in Mach and there will be one for each profile on the computer and they will have the name of these profiles.

I know that G83 for sure changes to G61.

I am retired now........used to have a young "whipper snapper" doing all these details for me :P
Its a lonely world now............have to look at the end of my own arm for a hand.
Thanks to all who answered my SOS ::)
