LaserGRBL Power Settings Messed Up

[chasehensley]

Hi all, I got Laser GRBL and when I want to set the laser to the lowest power I have to do S1000 not S1 and when I do S1 the laser turns on. This means that I can't get any GCODE to run because they all have their S#'s under 1000. Has anybody ever had this happen to them?

[StuartB4]

Do you mean when you enter S1 it turns on at full power?
What machine/laser do you have, and have you used other software that worked correctly?

[chasehensley]

No sorry, I mean that when I do S1 nothing happens the way I can get the laser to turn on at the lowest power is to do S1000. I have a 3018prover.

[StuartB4]

Have you enabled Laser mode in GRBL configuration settings?

[StuartB4]

One other thing, don't have the offline controller connected at the same time as the USB connection.
They don't like it apparently.

[chasehensley]

Ok, Ill try unplugging the Offline Controller. But how do I turn on laser mode? Is it just $32 = 1?

[StuartB4]

Yes. Make sure you are connected, goto Grbl menu, Grbl Configuration. Change $32 to 1 and make sure $30 is 255 or 1000. $31 should be 0. Then click Write and exit.

Hi, New to the laser, so I am having power problems. When I open GRBL the line numbers jump from $27 to $100. There is no $$30 or $31 can someone tell me what I am doing wrong. The laser comes on but does not burn.

[StuartB4]

@ taz101:
You need to have GRBL 1.1.
Start LaserGRBL and click Connect and it will tell you which version you have in the top of the window on the left.

[StuartB4]

You can update it using LaserGRBL.
Start it but don't click connect but make sure the USB cable is plugged in.
Goto the tools menu and click Flash Grbl Firmware.

Also, if it does'nt start when you have the correct Com port change it from Nano to Uno in the dropdown selector.

Thank you will try this later today Paul

Thanks! Is the Arduino Nano the correct one for a Sainsmart 3018prover? Thanks for all of the great information!

@chasehensley
Have a look at your machine controller board for the Atmel chip, the square one with the legs on all 4 sides.
It should be an Atmel 328P.
