I think he’s asking for you to enter $$ in the ‘console’ and it should print the configuration settings to the console.
You can scroll the console and ‘copy’ the text, mark the text and use ^c (hold the control key and press ‘c’) to copy the marked area.
Use any text editor and open a new file called config.txt and ‘paste’ (^v) the information there. Save and close the editor and drop the config.txt file on the reply window.

what am i doing wrong ??
I have made a Lib. item for low power etc to print onto paper…
Now by shifting the start position i was able to print the following:-
The Frame position does not match the actual lines position, that’s why the above pic shows the lines off the work area, if i shift the start position to home ie Top LH goes straight into belt slippage…

I can not measure the distances between the short lines. It is possible that the y-axis acceleration is set too high for the mass of the machine causing the lost motion. If the vertical lines are engraved consecutively and are generated at the wrong distance apart then we have a piece of evidence to point toward an acceleration based symptom.
On smoothie, it’s different - there’s a config.txt file on the SD card that ships with the device. FluidNC and some of the newer G-code (but non GRBL controllers) use a file and the ‘$$’ command doesn’t work. I poured over the smoothie docs and didn’t see a console command to pull all the settings. There is a ‘config dump to console’ command in Fluid NC.

I Just noticed your optical laser for framing in the corner of the picture you posted.
On occasion, I have seen this type of accessory reduce the available Y-axis travel. If the work area is not reduced in the settings (to match) it will crash into the rail closest to you and furthest from the limit switch causing the controller to lose position.
With the K40 powered down and the computer disconnected (wait a few minutes) then slowly move the engrave head the full distance of the Y-axis to confirm the physical travel distance available. Please measure this - a tape measure should be adequate.
We can then confirm that the axis length matches the Machine Settings.
In LightBurn, click Edit then click Machine Settings - then click the small > to reach the Output Settings. Please screen capture everything in this window.
Adding mass (weight / heft) to the engrave head can require lower acceleration values to prevent belt slip - So, I’m still not certain what’s happening.
After we get this sorted, the Pointer Offset setting appears in the Device Settings window. We may have to adjust this if there are inaccuracies between framing and work location.
The measured Y travel is 230mm
The Device Settings are Width=250 and Height=200mm
I have disconnected the cable tray and measured Y travel is 235mm
From home pos, on f2 iget:-
Looks like the cable tray was restricting travel, need to test other former’s, but looking good.
If this is the solution, have to work out how to get Air and Volts to the diodes.

Another test on f8, still producing layer displacement,
Start from current pos. ie Home. no chatter…
John You say:-
In LightBurn, click Edit then click Machine Settings - then click the small > to reach the Output Settings. Please screen capture everything in this window.
Have 2 choices Settings and Device Settings, Which one?
Can’t see “then click the small > to reach the Output Settings” in either window… Trevor
If the option to access the Machine Settings isn’t shown, it’s entirely likely that it’s only available and accessible in the Config File on the SD card. Smoothie is a new process for me and I’ll be ordering a C3D board right away.
I hope Lightburn is buying that for you… 
I just got a Makerbase MKS DLC32 … looked at it, but haven’t powered it up.
Hi John J
how is the acquisition of the new board progressing.

Hi John John “You said Smoothie is a new process for me and I’ll be ordering a C3D board right away”
Have you received the this board, and if so will u be posting, regarding the non alignment of cutting layers.
Regards Trevor Boundy
The board is here and I pulled the config.txt file off the card.
The most glaring thing for me is a distinction between the Endstop switches which are enabled and the limit switches are not active by default.
I have to grab a couple of things for a project / testing but i’ll hook the board up and attempt to talk to it tonight.
Tar. John
Just as a check for u, here is my config.txt file from my usb card

Hi John Johnson
Are still available to help me with my Cohesion3D displaced images problems ?
Happy New Year. John

This one got past me. My apologies for the delay.
If you select the reply button near my posts I will receive a notification when you respond.
This still appears to be a lost motion behavior where the head hits the limit and the motion steps are counted and the head can’t move. When the head comes off the limit, the real location and the ‘believed’ location are different.
I looked in the Config file and didn’t see axis length settings. It may be gathering this information from the switches. Have you installed all 6 switches?
I just found a resource that mentions that on some units the Y axis can hit the exhaust vent inside the K40. When the exhaust vent is removed the full length of the Y axis is available. With the exhaust vent installed inside the machine the Maximum travel is closer to 150mm.
If the gantry is colliding with the exhaust vent and preventing the limit switch from tripping that could be all there is to it.
With the power off, please confirm that the gantry (Y-axis) can move freely to both ends of the 200mm limit. You may want to reduce the Y-axis value of the work area to 180mm or less depending on what is available when the limit or end stop switches release.
Thanks John,
6 switches ?
Y axis one limit sw, supported by ribbon cable to Cohesion3D
X axis one limit SW, supported by wired cable to Cohesion3D
I chopped the exhaust vent on first receiving the M/C.
With power off he physical Y travel measures 230mm.
Powered up, using Lightburn Home to Origin Y travel measures 200mm

Hi Tim (MrMag)
I still have no reply from John John.
Do u think i should mark him as resolved, and re-start the topic again?
How do i get a general blog response?
I’m at a bit of a loss as to what to do Next.
Your advice appreciated Trevor
Please select the reply button next to my response so I receive a notification.
Even bettter, please use @JohnJohn so I don’t miss another response.
Good stuff!
With the project loaded up select Ctrl-shift-A
Then capture the screen in the same way you did above.
then Ctrl-shift-0 (control shift zero)
Then capture again.
I would like to see the workspace settings and if LightBurn is attempting to engrave outside or work outside what is allowed for your engraver.
LightBurn Home? This may be a user origin that you have set. Please capture the screen with the Laser window visible so we can compare.
I downloaded your config file and I see 200 x 200 as your work area.
Adjusting your x-axis in the config file to 250mm and turning off the absent endstop switches may be all that’s missing.
X is alpha, it’s homing to minimum so the switch is at x=0.
alpha_max_endstop should be set to nc instead of 1.25^
alpha_max will be set to 200 (again, suggesting 250 or more)
Y is beta, it’s homing to maximum so the switch is at y=200
beta_min_endstop should be set to nc instead of 1.26^
beta_min will be set to 0 (zero)
x_min (0) and y_max (200mm)are the correct placement for the switches:
We’re expecting the engraver home toward both switches in the back Left hand corner on start-up.
If the switches trip before the physical limit of the engraver the X will be set for 0 (Zero) and Y will be set for 200mm. If the Y max switch trips at 180 the engraver will attempt to go to -20 instead of zero. If the Y max switch trips at 220mm, Y will stop won’t go below 20mm.
Do you have a z-axis motor?
The alpha_max_travel, beta_max_travel and gamma_max_travel at the bottom of the capture should be left at 500mm That’s how far the engraver would be willing to go to get to the switch. These are ok.
