Just put my new sculpfun 9 together
Got it moving and all that stuff
Using light burn program
There’s power to the top of the doide
But the green light for the doide is not flashing
Took it apart at that motherboard and when I run program the light for firing doide is working on the motherboard
Thinking its the cable but not shore
Any help would be great
Before I send it back
I believe the issue you have is, as you enabled Z motor, when you try to engrave it immediately Alarm 2
What errors you have in console? if any
Does machine home correctly?
Also, inchs a min, thats very fast speeds you have set
@misken might also be able to help
Don’t have any errors gone up
Everything works
Just not burning
I know it’s set fast
I change that after photo
Speed shouldn’t stop it from firing
It’s just not getting signal to doide laser for it to burn
Also it don’t home
Ok so we got some progress
Homing ok, no errors
When you trigger the laser by engrave or fire button
Only some LEDs and fans come on correct?
@misken has this guide that makes sense to checK
5V test middle of page
Check if you can replicate
Only one led light comes on the head of the doide board
Try the 5v think
Still the same
Did the fire button
And the led light on the motherboard for the laser comes on and stays on until I push the fire button off again
It’s the same both ways if I plug into where it belongs and if I move to 5v plug
I am really thinking it’s the harness that came with the machine
I think I got all settings right in my machine
Just not getting the doide to fire on or burn
Definitly time to get in touch with manufacturer to get them to really help you diagnose.
Could also be that you got a bad diode - does happen - but still would require diagnosics
On the other hand, if you put all back togueher, and you do have a multimeter
You can test - on the cable end - just before it connects to laser head - for 24v and PWM signal. Should be easy to do too
Unplug that, and test by the labels on the module
Usually the PCb has margkings
PWM GDN and 12v or 24v so you can follow those

I think Gil already covered everything that’s available to check. If you can confirm that the cable works, then it’s definitely the laser head that’s broken. If you can send a video and report to Sculpfun support, they usually replace the head without any problem.
A side note: I recommend changing the speed settings to mm/min. I guess you are more used to inches, but just take this as a general speed metric. Otherwise, you need to recalculate 99% of all values you read in the diode laser world to your units.

Speed will stop it from firing or even running.You are right at the limit for an S-9. It’s top speed is 6000 mm/min. You are right there. The S-9 is s 5.5 watt output diode. There is no way you will even achieve a mark at that speed even at 100% power. I know, it was my 1st laser and I made the mistake of running it at or above max speed. There may or may not be, not a warning, but the reason as to why it failed to fire is under the Console tab in Lightburn. I am not a GRBL expert, but I am sure it is the speed setting.
Try to use mm/min. There is 24.5 mm/inch. The Sculpfun is a good machine imo, but slow. Great for fine engraving…just slow, which is normal. I upgraded to a S-10 module eventually, but the stepper motors are still limited at max 6000 mm/min.
Here is an example with the 10 watt…and I lowered the max output to 90% in settings (not good to always run at 100% full bore). Just a painted tile at 1300 mm/min at 13% power. Almost 1 1/2 hours.
