How do I correct this? Limit switches are not activated bed size is correct.
What is your distance set at in move window?
10mm
I have tried continous jog also
Questions to answer:
- Does the controller home correctly when turned on
- What does
Get Positionshow in the home position - Any CNC-style offsets in effect, like
G54 - Is LightBurn in

A list of the GRBL $# and $$ settings will be helpful.
Thank you for the replies so far.
I will get $$ values shortly…I am wondering if it could be a faulty control board.?
Honestly this is on my Sainsmart 3018, Has limit switches. I have used it before with a laser modul, then when Millmage was released I wanted to try Millmage.
I want to switch bach and use my UV moduls for marking small items…
It did work perfectly before.
Almost certainly not, because such problem are generally due to a misconfiguration.
And the GRBL settings have major problems:
$11should not be zero, as that allows no wiggle room while curve following.$20must not be zero, as that prevents the controller from detecting out-of-limit commands$24must not be zero, as the homing cycle will be unable to complete. Perhaps 100 mm/min will work better.$25seems very high. It exceeds the$110/111values and can never be reached$27must not be zero, as that prevents the homing cycle from pulling away from the switches$30is absurd. It should be 256 for the Arduino-class controllers typical for 3018 machines, with LightBurn’sS-value maxset to match$102cannot possibly be correct$120and$121seem very low, even for a leadscrew CNC machine, and$122being zero will prevent the Z axis from homing$130and$131do not match the physical size of a 3018 machine
Based on those values, I do not see how the machine could home correctly, which would explain problems with jogging or any motion at all.
So the first step is to correct those settings.
Then the $# values are likely incorrect for LightBurn, so check those, too.
You may be able to restore an automatic backup of the machine settings from before you installed MillMage or made any other changes:
However, you must verify those restored settings are correct for the machine, because they may have other problems.

Thank you, I was hopeing i could find someone with an actual working machine. I appreciate the reply and suggestions… I will correct the settings as above.
Switching between cnc to Lightburn can be a nightmare for those of us that are not software inclined.
I literally built a new machine so I didn’t have to spend hours trying to switch back and forth.
I started with the 3018 Pro. I swapped the spindle motor and laser module and only changed the Laser On/Off parameter once I got it set up.
So I corrected the $$ settings best to my knowledge. I do not get any errors, but machine will not jog.. The jog is enabled. I also notice that the laser will not fire. I have checked all wires to steppers, everything looks normal. Odd as I had this set up working before.

Give us another look at them, plus the output of $#.
Select + copy the lines from the Console, then paste them into your reply, rather than using an image or screenshot, so they’re easier for us to read.

So it still can’t home Z, which may be part of the problem.
Let’s find out what it does from a cold start:
- Turn it off
- Start LightBurn
- Turn it on
- Connect LightBurn to it
- Enter
$Hand Enter in the console to home it - Paste everything from the
Consolehere
The $H should cause the machine to home all three axes and stop 1 mm away from the switches. Is that what happens?
ok
XH

Then you must disable homing by setting $22=0 and home the machine manually:
Note that the two methods mentioned there are separate, but you must do one or the other every time you turn the machine on.
If you fail to manually home the machine, the controller has no way to know where the laser head is in relation to the axis limits, so motion commands (like jogging) will eventually fail.
Also, because homing is disabled, you can’t use the LightBurn Home button.
If you still get this particular error, especially right after you start everything up, see if the Speed in the Move window is set to zero.
When opening lightburn, The speed in the move window stays at what I had it set at. I am still on Version 1.7.08 of LB.
