Run GCode in mach3

[Plasron]

And the CNC machine torch doesn’t come down, But it runs the G Code, just not touching the metal and arching.
And help would be greatly appreciated
Ron

[Plasron]

The G Code is created on my home computer, I I backup the tap files to usb thumb drive, take it to my brothers and run them on the shop computer in mach3, I’m thinking this is where the problem is but I don’t have a clue how to fix the problem.

Have you defined the z axis in mach3... Ports and pins

Can you post a bit of the code

[acourtjester]

A little more info would help, like are you just starting out, first time cutting, did this just start happening.
What is the equipment you are using, what software are you using the the G-code generation.

[Plasron]

Thanks Robertspark
I will have to post from my desktop I’m on my iPad right now, but, I will post in a little while.
I will have to check the Z axis in mach3, it may be tomorrow since it’s on my brothers computer 15 miles away.
Thanks for helping me

We have been cutting tap files in mach3, but now something has gone haywire , that’s what I don’t understand why all of a sudden it’s not cutting
Thanks

Hey robertspark
how do I post a tap file here
thanks

You can copy and paste it within a code box

.  Insert gcode 

[djreiswig]

Are you using the correct sheetcam post processor?

I'm sorry for being so stupid but where do I get the code from.
Thanks

I using Mach3 plasma processor.

The gcodefile, if you open it with a text text editor (notepad) and then just copy it.

Then when you press reply to this post when the editor pops up you will see a button that looks like this "</>"

Press the button and paste your code between the "

Code: Select all

[\code]" that it inserts

I think you are using the wrong post processor.... That is a milling post processor for mach3.... It changes the z axis height as it steps through the code....

Thanks robertspark
I saw some where on the Sheetcam forum Les suggested to a user yo use Mach3 scribe without backlash.
I'll try that.
Your help is greatly appeached
Ron

[robertspark]

why not use the Mach3 plasma post?

Do you have a scribe?

{maybe you need to give us a full explanation of what you have on your plasma / what you intend to do with it
Are you running Mach3, Mach4, UCCNC, how are you touching off {G31 or G28.1}

How do you use the scribe (what M-code)

No to the scribe, all we are doing is plasma torch cutting, mach3, don’t know what G31or G28.1 it is rocket science to me.

I will try Mach3 plasma post and see what happens.

Thanks for your patience with me and thanks for the help.
Ron

[robertspark]

Option A, copy your profile, rename it to txt and upload it... Or open it with a text editor and paste it into that </> code button like you did previous

Option B, go into mach3, config, ports and pins and take screenshots of each of the "inputs" screens.... (You may need to scroll down)

How are you driving mach3, are you using a parallel port or smooth stepper or something else?

G31 is the gcode for probing.... It uses the probe input
G28.1 is the (mach3) gcode to reference an axis.... It uses the "axis home input"

https://machmotion.com/cnc-info/g-code.html

[robertspark]

Sorry, my mistake....

If you use the Mach3 THC with scriber, that one includes for a touch off routine (you were right.... {I've now looked at the post processors code}

You WILL need to edit the post processor to your settings.... it should be relatively straight forward / clear:

Note, sheetcam uses MILLIMETRES..... so you will need to convert all imperial units {inches} to mm (multiply be 25.4).... you then change the sheetcam settings to operate in inches if that is what you work in

Code: Select all

--************************************************
--*** Set these values up to suit your machine ***
--************************************************

--this is the distance between each torch reference in MILLIMETRES
refDistance = 250

--this is the reference feed rate in mm/min
refFeed = 500

--Put your switch offset value here in MILLIMETRES
--Put a sheet of metal on your machine and place a sheet of paper on top.
--Slowly jog the torch down onto the paper until the touch-off switch just operates.
--Zero the Z axis then pull gently on the paper and slowly jog up until the paper slides out.
--The Z axis position is your switch offset.
switchOffset = 1.5

--Scriber X,Y,Z offsets in MILLIMETRES. Do not use inches here even if you want inch code
--Use the special code 'nil' on the Z axis to disable it.
--In that case no Z values will be output at all while scribing.
--e.g scriberZ = nil
scriberX = 110
scriberY = 220
scriberZ = 0

--scriber axis. Leave this as nil if the scriber is fixed to the same axis as the torch

Sorry, my mistake....

If you use the Mach3 THC with scriber, that one includes for a touch off routine (you were right.... {I've now looked at the post processors code}

You WILL need to edit the post processor to your settings.... it should be relatively straight forward / clear:

Note, sheetcam uses MILLIMETRES..... so you will need to convert all imperial units {inches} to mm (multiply be 25.4).... you then change the sheetcam settings to operate in inches if that is what you work in

Code: Select all

--************************************************
--*** Set these values up to suit your machine ***
--************************************************

--this is the distance between each torch reference in MILLIMETRES
refDistance = 250

--this is the reference feed rate in mm/min
refFeed = 500

--Put your switch offset value here in MILLIMETRES
--Put a sheet of metal on your machine and place a sheet of paper on top.
--Slowly jog the torch down onto the paper until the touch-off switch just operates.
--Zero the Z axis then pull gently on the paper and slowly jog up until the paper slides out.
--The Z axis position is your switch offset.
switchOffset = 1.5

--Scriber X,Y,Z offsets in MILLIMETRES. Do not use inches here even if you want inch code
--Use the special code 'nil' on the Z axis to disable it.
--In that case no Z values will be output at all while scribing.
--e.g scriberZ = nil
scriberX = 110
scriberY = 220
scriberZ = 0

--scriber axis. Leave this as nil if the scriber is fixed to the same axis as the torch
--scriberAxis = "A"
scriberAxis = "K"

--The cutter will slow down for corners and turn off THC below this radius
slowRadius = 10

--Minimum slow down speed.
--This is a scale factor. For instance 0.5 = 50% of the current feed rate

Thanks
I am so overloaded I’m about to blow fuse, I know I need to take a break CNCing for a while, maybe take a break until after the Holidays.
Thanks for your help

I give up trying to process DXF files on my home computer and bring my brothers computer home and process them.
The man that my brother bought the machine from has the tool set, Mach3 flame with THC-g31 edited, my computer at home doesn't have the edited mach3 flame with THC -g31 edited.
Thanks to all of for your help

Copy the working post processor + toolset from the working machine to the unworking machine?

Thank you robertspark
I forgot to do that when I had my brothers computer, I will make a copy on a USB thumb drive when I go to his house today.
I really appreciate your help

Went in program files (x86) , Sheetcam TNG, Post, and the edited file is not there.
