Post Processor Issue

MikeJones86 · August 26, 2019, 10:52pm

I know most guys here might not use GRBL for controls on a CNC Plasma Tables, but any leads would be awesome. I’m going to go on Autodesk site and see if they have another Processor for GRBL.
But here is a picture of the error I’m getting when trying to post.

this post does not support your machine…

MikeJones86 · August 27, 2019, 6:39pm

Well I’m going to search for more seems like GRBL post haven’t been working from a little looking on Autodesk site

MikeJones86 · August 27, 2019, 7:35pm

Okay so when I got my machine he gave me this file to use for the Post Processor in another Program so couldn’t add this into my Fusion 360 post processor library to use.

Its also Java Script here it is below:

firstPierceTime = 0 --this is an extra delay added to the first pierce as needed by some machines

function OnAbout(event)
ctrl = event:GetTextCtrl()
ctrl:AppendText(“GRBL plasma post processor\n”)
ctrl:AppendText("\n")
ctrl:AppendText(“Generic plasma post for machines with or without THC\n”)
ctrl:AppendText("\n")
ctrl:AppendText(“Modal G-codes and coordinates\n”)
ctrl:AppendText(“No comments\n”)
ctrl:AppendText(“M03/M05 turn the torch on/off\n”)
ctrl:AppendText(“Incremental IJ\n”)
end

function OnInit()

post.SetCommentChars ("()", “[]”) --make sure ( and ) characters do not appear in system text
if(scale == metric) then
post.Text (" G21\n") --metric mode
else
post.Text (" G20\n") --inch mode
end
bigArcs = 1 --stitch arc segments together
minArcSize = 0.05 --arcs smaller than this are converted to moves
firstPierce = firstPierceTime
end

function OnFinish()
post.Text (" M05 M30\n")
end

function OnRapid()
post.ModalText (" G00")
post.ModalNumber (" X", endX * scale, “0.0000”)
post.ModalNumber (" Y", endY * scale, “0.0000”)
post.ModalNumber (" Z", endZ * scale, “0.0000”)
post.Eol()
end

function OnMove()
post.ModalText (" G01")
post.ModalNumber (" X", endX * scale, “0.0000”)
post.ModalNumber (" Y", endY * scale, “0.0000”)
post.ModalNumber (" Z", endZ * scale, “0.0000”)
post.ModalNumber (" F", feedRate * scale, “0.0###”)
post.Eol()
end

function OnArc()
if(arcAngle <0) then
post.ModalText (" G03")
else
post.ModalText (" G02")
end
post.NonModalNumber (" X", endX * scale, “0.0000”)
post.NonModalNumber (" Y", endY * scale, “0.0000”)
post.ModalNumber (" Z", endZ * scale, “0.0000”)
post.Text (" I")
post.Number ((arcCentreX - currentX) * scale, “0.0000”)
post.Text (" J")
post.Number ((arcCentreY - currentY) * scale, “0.0000”)
post.ModalNumber (" F", feedRate * scale, “0.0###”)
post.Eol()
end

function OnPenDown()
if (preheat > 0.001) then
post.ModalText (" G00")
post.ModalNumber (" Z", cutHeight * scale, “0.0000”)
post.Text ("\n G04 P")
post.Number (preheat,“0.###”)
post.Eol()
end
post.ModalText (" G00")
post.ModalNumber (" Z", pierceHeight * scale, “0.0000”)
post.Text ("\n M03\n")
if (pierceDelay + firstPierce > 0.001) then
post.Text (" G04 P")
post.Number (pierceDelay + firstPierce,“0.###”)
firstPierce = 0
post.Eol()
end
end

function OnPenUp()
post.Text (" M05\n")
if (endDelay > 0) then
post.Text (" G04 P")
post.Number (endDelay,“0.###”)
post.Eol()
end
end

function OnDrill()
OnRapid()
OnPenDown()
endZ = drillZ
OnMove()
OnPenUp()
endZ = safeZ
OnRapid()
end

under the dropbox labeled “any vendor”
then go to Grbl
There are two post for Grbl, one is for milling and the other is for laser, water jet and plasma.

so downloaded it and this was the outcome

So Then change it to Laser instead of Plasma and got this.

I could delete the S Values and give it a shot to see if it will work

ChuckCantieny · September 2, 2019, 3:08pm

Sorry it’s a little late for an answer.

Did you try changing any settings (values) in the Property window of the post processor dialog box prior to processing? I am using the Grbl mill post processor for an Arduino/Grbl mini mill. I had to set Output M6 and Output Tool Number to NO or the post would give errors. I don’t know what the laser/plasma post processor looks like. Also based on the errors being tied to “ProgramName” you could try playing with the “program name or number” in the post process dialog box.

Chuck

DanielLyall · September 14, 2019, 3:43am

Can you post that post

MikeJones86 · September 16, 2019, 12:47pm

Okay sorry been busy lately. So here is what a program looks like G-Code wise off the other CAM program.
So what I’m seeing is deleting the header from a Fusion post maybe it will work.
