I have used while and do loops for years to wait on an input signal. I have never seen one programmed correctly that did not work in Mach3.

IF you have ever watched a real comercial plasma cutter OR laser cutting thin sheet goods  they are WICKEDLY fast on Accelleration. Most use an Scurve planner that makes it not only wickedly fast but very smooth . Almost ALL runs servos. There are also designed with very low inertia Drives and gantries and are very rigid as well.  

Now that said A well planned Mach3 CNC plasma is a GREAT machine for the money and the normal useage for the average users.

Looks good from here(;-) Good Job. One thing I do notice is it may be a problem with a heavily nested cut and using an offset probe as teh probe could easily end up in a hole from a previous cut. Maybe consider a compromise of your earlier design where teh Air cylinder was on a slight angle to help slide teh probe tip under teh Torch tip ???

Also keep teh sliding Z as a backup to the touch probe. Even though I have RARELY ever seen teh G28.1 fail to cycle. But a backup would be nice to have set  up as a safety.  IF you do not have a breakaway torch mount each time you crash the head and break the torch insulator sleeve it is a $100 bill.

BUT then you get to learn how to get GOOD at repairing those sleeves (;-).

YEP there is an ART to plasma cutting that most millers or routers do not understand. The real trick is to maintain Constant velocity for cutting. Slowing down for a corner does not make any sense for plasma cutting (;-)

THAT is another chapter in teh book(;-)

I do not think that is true "" mach does not read inputs within a while loop. ""  Can you give me an example of where you  that is true ???

IF you want a quicky test  Load your cut file then where 0,0 would normally be  set hit zero axis X zero axis Y  the do a regen to set teh toolpath exactly .

NOW simply move over to a new Origin Hit ZeroX then ZeroY  then look at teh toolpath it is basically the same with just teh cross hairs moved over to the new 0,0  . It will be that way UNLESS you make a move that is WAY off teh table size then it will show the far off offset.

I spent YEARS working with Mach3 plasma making all kinds of time saving gizmos for the shop here. They cut 5 dys a week 8 hrs a day most of teh time.  This like autorestart of a torch cutout. auto indexing right , auto indexing up , Preveiw cutting, G68 rotation to fit teh part to the material,etc,etc.  I was using teh Sword and T word long before it was popular to do so (;-). When CandCNC came along here I heaviely redid a lot of the functions like I used his Cut table and Mach3 tool# to autosetup cut files based on the tool#.

But like I said that is another story. I tried to get the Website to setup a specific plasma cutting section but that never happened so a lot of things over the years just all got blended into the mainstream Mach3 stuff. ANd  A lot never made it here. I have stacks of notebooks somewhere on teh plasma CNC process and Mach3.

By simply resetting 0,0 you will NOT change any thing in the toolpath other than where 0,0 actually is.  It will NOT effect teh cutting nor even change teh toolpath unelss you are 9 miles off teh tool table in relation to teh toolpath.

Test it you will see (;-) You do not need to regen to make it all work correctly. When you regen you are recycling ALL of teh G28.1 in the file THAT is what effects teh Z values. Same if you try to do a Run from here. The Z will end up WAY OFF position.

Now if you MUST have it then you need to program around teh problem. At the beginning of the script record teh actual Z value and save it to a variable then after teh Regen routine runs reapply teh Saved Z vale BACK to the  Z DRO value. I do the same trick for teh Run From Here routine so I do not have to worry about remembering to reset teh Z value back to position before it runs. BUT that is another chapeter in teh CNC plasma cutting book Making teh Run from here work properly so that you can restart Plasma cutting. AND YES teh RFH in Ver .067 is different than other versions (;-) It looks like Art tried to fix it for Plasma cutting but did not quiet get it right.

Comment out the last 4 lines of the button code  They are not needed.  

IF yo insist on using it then add in another line at teh end

Just so I do not have to do a search to figure it out is this a LPT ver or an ESS version ??

You can leave it that way IF you want OR you can change it back to use the initial move. Setup / portPins/Millsetup   THC settings , check teh box initial move for G28.1.

Personally I like the initial rapid move, but you have teh choice.
