open builds cam/controll for plasma

Post the files please

Sounds more like your plasma setup is not done correctly though. Or EMI messing with things (hopefully you don't have a HF Start plasma) Did you watch the Dr D Flo plasma Videos?

 

It should, and does. Check the gcode you'll see the M5 (tool off) at the end of the vector.

Without more details best we can offer is guesswork

Gcode, workspace export (OBC file) screenshot of CAM > Settings tab > Settings button page to see what you maybe changed from defaults, or forgot to set up, and a Grbl settings backup at least

 

We don't need a video. Didn't ask for video either. We need the files mentioned above to take a look for you

and

Refers from earlier replies. As soon as you add the info we need we can move forward, constructively

 

Watch the Dr D Flo video around 33min20 second in he cover CAM. Note video is older, things he complains about has been fixed/improved since

 

• Post the Lightburn Gcode too (do they even have proper Plasma support? Its not a laser after all - Lightburn is a Laser CAM. Plasmas need extra Z moves, Material touch off, Pierce delays, Pierce vs Cut heights etc) - if it works for you in Lightburn its probably that you have your machine configured more as a laser than a Plasma - and thus fundamentally wrong.
• Post the Grbl settings backup (CONTROL > Grbl settings tab > Backup Grbl Settings button on the top toolbar) i am expecting your $3x parameters to be incorrect (we use Grbl defaults of $30=1000, $31=0 and $32=0 to turn the relay on)
• confirm, you are triggering the Plasma off the spindle output, using a relay.
• You are running stock standard Grbl 1.1 as expected? Not some 3rd party version of Grbl?

The gcode out of CAM looks good. Open it in a text editor and read it (would benefit you a lot to read basic gcode and understand the commands)

Get a BlackBox (; it makes it all easier

 

Awaiting

And

In regards to:

Doesn't sound familiar, take a screenshot of what you are referring to

Ps: i cant see a probe switch in your video, yet you have Touch Off commands in one of your GCODE uploads. Stay aware of that and either dont enable Touch Off, or fit a switch and floating head so you can enable it

 

No you need the tool in settings. Touch off is under the toolpath parameters.

Ours is standard, lightburn is for lasers, not plasmas

 

For two days now, i keep asking you:

I cannot offer any more assistance until you add the information I ask for, and also answer all the questions (you answer sporadically, short, and without details, it feels like you post random files, i ask for Grbl settings backup files, you paste from serial console of a different host - very hard to assist you if we cannot work logically toward a point.

Now please post the Lightburn gcode so i can compare it for you.

 

The Lightburn Gcode includes M8/M9 (Coolant outputs) - are you sure you don't have your relay wired to the Coolant or Spindle Direction outputs instead of the Spindle PWM Outputs by mistake?
See gnea/grbl

Grbl Settings tab along the top, button is right on the toolbar


For us working the support side of things, this format is much easier to read than having to lookup parameter numbers.

The file you provided as "grbl settings" didn't come from the button above, and thus was harder to work with for us (seems you copy pasted it from the host application)

If you don't know what a Host is, see docs:software:overview [OpenBuilds Documentation]

The Host interacts with the Firmware to stream the Gcode created by a CAM. Explained in the link above

See the difference, the nice Backup out of CONTROL has the descriptions etc which makes checking the settings so much easier, yours was from somewhere else and missing this detail. Now the support guy (in this case me) has to go cross check some parameters against the Wiki to check the values, taking a long time extra.

CONTROL backup on the left, yours on the right... Not easy to check.

Each time you post things are a little different, so how can I continue down a troubleshooting path with you?

Yesterday in file "modern settings.txt" in post #15, you had $32=0 (as it should be)
Today, in file "grbl factory settings" you have $32=1 (which is wrong!)



So please set $32=0 (Disabled) - It's a plasma, not a laser, trying to use Laser Mode (and a laser CAM like Lighburn) is effectively incorrect


You can do so from the Grbl Settings tab:

 

We are past that point by now... Was just showing you where it is

I asked you to change Laser Mode to Disabled

and to recheck your wiring:

If you have a more electronics and computer inclined buddy to invite over for a beer, it would help too

 

Correct, your Grbl Settings now at least shows $32=0 - don't change it again (; - leave it!

Feedrate is set in CAM, if its slow, you typed a low number into Feedrate (I assume, you didn't attach the latest Gcode so I can check it for you)

Still waiting on you to check your wiring again, post some pics of how you have your relay wired (clear pics) so we can see if thats the issue: as per

 

Read up on gnea/grbl - reading all the pages is highly recommended
