Hi There
I have a Redsail 5030 which I have replaced the board for a 3d cohession one
I have found that the laser has only a very weak beam ,not enough to cut paper
After changing the tube and replacing the power unit with a cloudray 50w one,
nothing has changed
Next I have tried to access the console settings ,but get denied when typing $$ with
error:Invalid statement
the old K40 software was deleted after the new one was installed, weather this is the problem I do not know

The Cohesion3D board is SmoothieWare, not direct GRBL. However, LB makes it relatively easy to modify your setting by using Edit->Machine Settings to check any relevant settings.

[jkwilborn (Jack Wilborn)]

Just curious, why did you change out the controller? Didn’t it come with a Ruida of some type?

[lofty (Dave Soppitt)]

Thanks for replying
The machine is running Smoothieware ,I did try GRBL at one stage
I have looked through the settings but can not find anything that helps
I have watched a video on changing laser value settings in the console box,
but then I try to access the console settings
the error comes up,and I can not check the 2 laser setting values

@TomWS

Edit->Machine Settings

Did you go there?

Sounds like you’re in the console, right idea wrong path…

Hi the machine is a Redsail m3050 with a m2 nano board
sorry about the typo did it on the fly

Hi
Edit settings above device settings is where I looked

The first and best place to troubleshoot this configuration issue will be the support forum provided by the nice folks at Cohesion3D. Getting Started - Cohesion3D [←click]. They offer a ton of very helpful information on how to get setup and configured properly.

[lofty (Dave Soppitt)]

Thank you all for the help
I will try Cohesion3D

My bad for making the suggestion I made. Shows how long ago I changed the settings on that type of system.

With SmoothieWare, the configuration settings are fixed (the kind you’re looking for, I think) and contained in a txt file called “config.txt” and to change them you need to manually edit the file. The file is on the SD card plugged into the C3D board. The docs on the C3D site will tell you what the settings mean and how to adjust them. For a more comprehensive explanation of the settings, check out
http://smoothieware.org/
Sorry about the misdirection.

I really am grateful for your time and help I am really out of my depth and taking a crash course
cheers Dave

I have compared the config files and there are differences between mine and the latest smoothieware files
the laser module max power 1.0 max duty cycle
laser module min 0.0
default setting is 0.8 these settings are the same in old and new programs
can I change these settings while operating the machine ,or do I auto eject the card and flash the program
When I had the machine going on the old card I was running it under 10 ma as a max power
with no problems

I’m sorry, but I’m missing what the difference is between ‘mine’ and ‘the lastest’. You only gave one data point. And, in fact, max 1.0 duty cycle and min. 0.0 are the correct values when running on LightBurn. LB will scale a cut power setting of, say 75% to 0.75.

can I change these settings while operating the machine

No, you need to power off the laser, remove the SD card, edit the file, re-install the SD card, and repower your laser.

Hi
I have been looking through the configuration options in smoothiewares site
laser module proportional power true
on my machine I have, switch laser fire enable false
are these the same thing as they are both in the same place, bottom of laser options

[TomWS]

I don’t think so, but I’ll look at my saved config.txt file tomorrow and let you know what I have. It’s for a K40 run with a C3D board, but the LB Laser interface should be pretty much the same. I’ll snip the Laser section and post it here.

[TomWS]

As promised, here are the laser related settings in my K40/C3D config.txt file:

Note that only PWM output is used, the Laser Enable is disabled. (hardwired on)

Thanks for the settings
they all match mine
