Wasn't exactly sure where to put this question. But this is like the third time it happened to me. Upon the initial startup I'll home out the axis, go to MEM, select a g-code file, then I hit start. And it'll race through the g code like the entire program was full of G0 commands. If I had a part in the machine it would have crashed.  It's like it ignored every G1 command. Once the cycle is done, If I hit start cycle again, it'll go through like it's supposed to. The strange part is, it does not do it every time. Is this a configuration issue or a G-Code issue or a Linux issue? 

It's also known as chip breaking in mill G-Code. G83 and G73
The cycle sets final depth (X), retract position (R), peck depth (Q), and feed rate (F) normally used for drilling process. It's also handy for breaking stainless steel instead of getting birds nests or for live lathe tooling. Since my setup utilizes a grinder, without a pecking cycle it can stall the grinder out.
Right now I have to program a "peck" cycle manually. An example of this is:
G1 X2.02 F1
G0 X2.01
G1 X2.03 F1
G0 X2.02
G1 X2.04 F1
G0 X2.03

More pictures.

I have a simmilar 15k rpm Kessler spindle on a DMC 100 V.

I have attached the datasheet pictures.

Thanks for your quick reply.
Unfortunately the slots I need are open lines.
So no lead ins.
What I tried is using the puddle jump at Pearce hight. No pierce delay but a puddle delay. It seems to work well. But you don’t really have much control over plunge rate.
Is there a better way of doing this?

How do I fire the torch while the gantry is moving?

You need "lead in" for plasma cutting, you have that option in the included wizards for stuff you draw in LinuxCNC, and you will need a CAM software for other stuff to add those, probably SheetCAM.
BTW, you can start the torch while moving, but that will leave uncut sections on thin material and not cut at all on thicker material, but it will ruin the nozzle really quickly.

I must make changes to in jogscale..

I am experimenting with cutting straight lines for a screen.
Problem is this. On start and end of a line there is a hole that is bigger than the rest of the line. 
So I figured out how to edit a cut file by hand so it does stop the torch while the torch moves. So I get a perfect ending on the line I cut. 
Question is there a way I can get the torch to probe the metal, then accelerate to cutting speed for say 10 mm then turn the torch on at pierce height. 
And pierce while the torch is moving. Start point of cutting is not crucial but cut width at the beginning of the cut should be as close to the rest of the cut as possible.

Yes, Debian deserves some kind of prize for the dumbest login screen possible.

In addition to the jog enables, you need to do a similar change with the mpg count pins
that is, for example both joint.0.jog-counts axis.x.jog-counts must connect to the mpg count.

I made changes but still not working after homing.

Thank's for your replies. It's the login screen thats not clear!
As you say it wants the user name in the top of the two rows but there is no indication that that is what it needs.
All sorted now
Thanks again
John

Yes.

Just add the axes too

You need to "attach" the file with the "attachments" button then "include" it into the post.
