I’m still fighting the problem of the machine stopping mid process. I’ve even adjusted the computer ports so they don’t “sleep” and swapped ports and cables. The problem persists. I’m thinking the motherboard may be faulty.
Could be power supply heating up. Try this…
Using the program that quits before finishing, set the laser power to 5% and run the program.
Same place in the program?
Same time from the program start?
I’ve tried low power (very low), the machine stops in random places. However, it does seem to go further in the process with very low power.
This is often reported when there is a bad or sub-standard USB cable. Further is a relative term, but it seems that overheating of the laser module or power supply is low on the suspect list.
Just out of interest, would the use of the SD card to run the job rule out the computer side of the problem.
How do I use a SD card? My laptop has no port for a card.
The process may run a few seconds or a minute before stopping.
Hi David
I am assuming the machine itself has a slot for SD card.
I thought most machines do. I got my snapmaker a few days ago and it has a card reader and SD card in the box.
No expert here David, but I think you can put the Gcode on the SD…Load that into the machine slot provided, and the machine works independently.
If I have that right & your machine has that function.
Ps: I have often heard it said that usb cables etc can be a bit untrustworthy and good quality ones should be used…they dont have to look bad to be less than required.
Best advice though…is go through what the people here advise cause they got knowlege and experience.
Of course, we can’t exclude the mainboard, but this is VERY unlikely. Those usually don’t cause any issues with connectivity.
Number one cause is the connection itself, bad USB cables (swap again with a really high-quality one), remove electrical disturbances, do not power any other device from the same power line, try a different control PC. Exchange the power supply, the delivered ones are often weak and susceptible to voltage drops.
If all of these fails, then you might try to swap the mainboard as well.
