Plasma Torch Off while moving

Post by xrxlee »

Hello,

I am looking to convert my machine from Mach3/ESS with external torch height controller(Neuron CNC) to Acorn.
The plasma power supply I am using is a HPR130.

Currently, I have Sheetcam output the torch off command 0.02" before the end of cut, while keeping the XY motion toward the lead out.

This allows the torch to ramp down the cut to prevent blowing a hole at the point which the torch intersects the lead-in path.

Will Acorn be able to continue the XY movement as the M62 command is called out?

Thanks
cnckeith

thanks for the post, with lead in and lead out moves turning the torch off before the end of the final xy move is not necessary?
can you help me understand the requirement for this feature what case requires this? thanks!
we have a nice list of "icing on the cake" features that we are prioritizing to begin work on for the next release of Acorn CNC12 Plasma Software so let me know and we'll get it on the list. (Note: future updates are free of charge for at least two years and after that will be very reasonably priced.)

xrxlee,

Can you post a snippet of code that you are currently running?

If you are making a 4" cut then I'm assuming you have something like this?

G01 X3.98
M5 or . . . (torch off)
G01 X4.00

I also am currently using Mach (waiting on building space to put my new plasma with Acorn together) and I stop my contours .02 short as well. I do not continue the motion, just retract from there. Maybe I'll look into this method of continuing past with torch off.

Acorn does not have a setting to keep x y motion before turn off the torch at end of the cut . acorn does support sheet cam settings
could you post the macro your using in sheet cam that does that feature . The setting in your code snippet i like to try the code on my acorn

Keith i discussed this with you before . this is needed at the end of a cut . once all motion is stopped it take Hypertherm about 300 mili sec to turn off the torch . so a dink will be made in the cut . And no we don't use lead outs not every cut can have a lead out . i discussed this with joey to. same thing as needed second cut speed setting for holes
