Phecda changes $3 every Startup

Hi guys,

I’m running a phecda with limit switches on the right (x) and right back (y) sides.

I have to turn off $3 for x and y in the machine settings to make the laser move correctly.

Sadly, every time i start up LB and the Laser, $3 for x and y are turned on again.

How can i make the change permanent?

Best regards

Not sure what you mean. You can’t turn off $3.

Zero is not “off”, it is a parameter binary setting. of 0-7. Did other software come with the laser? The controller may not allow updates using the GRBL command structure except with a special program.

True, it’s not turned off.

It’s just the switch i meant that is directed to “false”.

The laser didnt came with additional software but elegoo sells this with lightburn compatibility so i would expect this to work.

The thing is that it took the change in $23 permanent without any problems.:sob:

I can see where that appears as an on/off. It is really a Bit 0/1 switch. Still, strange you can change $23 and it sticks, but $3 does not. They both use the same binary table for the settings.

Can you enter $$ in the Console and tell me the current value of the $3 parameter. Maybe it will retain if you enter the updated value through the Console window.

Do not try to use this table yourself, at least not for now. I just pasted the table here so I do not have to hunt for it again.
