Troubleshooting Machine Freezing at a job start

I found similar issue here > original thread:

How to debug?

Same questions does it occur with the laser power disabled? It can be a sign of a faulty PSU, in your case the strange part is we had now issues with this device and it was an ex demo crafty with a fair few hours. Try pulsing the laser before running the job. Try restarting the machine. Try disabling the laser, run the job and then turn on the laser. (Keyswitch) How many devices do you have pluged into the same power circuit, while the lasers dont use alot of power on average they do peak. T…

Laser plugged to a socket with just a smartphone charger. Other devices in the heavy-duty extension cord. pulsing before the job HELPS restarting does not help with keyswitch ON > you need to pulse before job | with keyswitch OFF > works Conclusion: In order to make it work PULSE before job, but that is not a solution. Any other ideas? Thank you

Hi there again,

Update:

• chiller + filtration has its own electricity connection
• LASER is connected to heavy duty extension cord directly to the socket

Not even a PULSE before the job helps.
New workaround is to start with engraving (low powers) then cutting and after a while it works just fine. Seems like the machine needs some time to warm up a bit and then it works. Let me know your thoughts.

thank you,
Martin

@_agoodguy I think we will need to arrange a new power supply, I am just confused to why it just suddenly happened as it was working so reliably before we sent it to you.

@FabCreator Could it be anything with the connection inside of the machine that changed during transport? (weak connectors, pcb supports,…) As I mentioned problem occurs at the beginning after some pause but I am hesitant to open it up just like that.

If you think that would solve the problem, let’s arrange it via email.

Thank you for the support!
