The problem i have is, that it doesn save the $32=1 command. If i unplug the controller and connect it again, it shows 0 again. Limits or steps can be changed and it saves them. But $32 always goes back to 0.
Even if if stop or end one job, the value goes back to 0 that i have to manually set it with macro to 1 before every lasermove. Otherwise it moves very weird and does not start engraving.
I donāt remember where the 1264 stores these values. Seems to me they are in non volatile static memory area.
Did you check the grbl version?
I think you should be at 1.0.1 or something. It should display it at the boot.
Itās supposed to keep it, donāt know what to say except maybe hardwareā¦ New board is $25 on ebay. Might ask at the originators site.
In lightburn Iāve used the āmachine settingsā under edit to set them on the Ruida, it probably works the same with your grbl machine. Did you try that angle? Maybe it will come up with something usable.
I could be that that GRBL build doesnāt work for lasers (despite AliExpressās claim - I know this comes as a surprise). It is relatively simple to update GRBL to the latest (1.1h) from github.
Some data need to be permanently stored on the microcontroller so they are stored in eeprom memory, this memory is sensitive to fluctuations and voltage levels and may interfere with its operation, are you sure the output voltage of the power supply is constant and It does not any oscillation?
As was stated by Ashkan these values are usually stored in non volatile memory.
Iād change a different one and see if when itās restarted it was retained. If itās working differently from the other variables that could be an issue somewhere else. Donāt forget to reset it.
I thought there was a 1.1h out there, but Iām not sure.
You should not have to set it every time itās reset.
This has come up before and you can probably search out some previous threads about it.
Apparently a few board makers ship out ānon-standardā grbl builds that ābreaksā some functions.
Iām sure the āresetting $32ā is one of the things thatās been mentioned before.
Thatās about all I remember but a little searching should dig up more.
Good luckā¦
Lol. It works now. I just updated to the latest version and it saves the value now. All other things are still working too. Seems the chinese pcb has the same layout and nothing Changed.
