T2 Engraving / Re: Thanks Zax

The torch (flashlight to Americans) in a rubber sink plunger is genius!

Regarding the hatch, likely the paths are not closed.

It sounds like you have understood correctly. There are some pictures around somewhere showing the hook up, I think nottingham82 posted one.

It is possible but I think there must be something else wrong. During raster engraving the laser is switching on/off so it should not be overheating, in fact I don't see much if any temperature increase after hours of running.

Let me consider the best way to implement this, perhaps after so many lines of G-code it could pause.

I agree with everything posted but would also not use the PDF import although it works you get better results with DXF.

You can easily correct it using the Calibrate Distance feature in the Settings / Advanced menu on the Laser Control screen.

Does this work any better?

It sounds like you have a few issue.

Have you changed firmware or use another program that may have changed parameters.

Are you displaying machine or workpiece coordinates?

You may need to Clear Grbl Positions, it's in the Machine menu. That should fix the Y-offset issue.

When you do the axis calibration, are you entering the expected and measured values before clicking calibrate?

So if you run the 100mm file and it comes out 80mm in both X and Y you would enter as attached.

Excellent job! That's a very nice clean engraving with a lot of detail.

M05 disabled the laser, it should not be required until the end of the job.

M03 S0 turns the laser to off and is used between paths.

If your firmware / machine doesn't work with power control then you can use the Laser D12 post processor which will send the M05 instead of the M03 S0.

T2Laser has many settings and features to work with most combinations of machine and firmware.

It may help to post the DXF?

Can you turn the laser on and off with the manual controls?

If so the firmware is correct, since the non-PWM uses D12 and the regular uses D11 (TTL pin) you can use this method to determine if you are using the right one. Then the G-code should work as expected.

I'm wondering if you haven't enabled the wrong post processor or a setting that is causing this, you can restore the defaults from the Help menu.

You also mentioned the firmware that worked, did you test that with T2Laser - if it did the same thing it's definitely settings.

Perhaps unrelated but some general comments, with the Non-PWM firmware the laser max should be 255, since you can't adjust power. 0.02 is an incredible small resolution, your laser is likely 0.12~0.18 in diameter when focused. I typically use 0.16 and get no lines and the fastest engraving times.

(I'm good with keeping the conversation going here, but if you prefer a new thread that's fine too)

You can use any Grbl firmware with T2Laser, it isn't software dependent.

I suspect you are using my non-PWM firmware, which controls the laser using D12.

It depends on the firmware, if you are using my default it is compiled to support 2 normally open home switches at the lower left (0,0 corner) wired in parallel to D9.

I also include firmware that expects 2 separate home switches, one on D9 and the other D10 (which allows you to wire them as normally closed if desired) and another for a 3 axis system where Z is homed first and then the XY.

I see them now, and no it's not an Eleks Mana board but it is a copy.

So it may not have a jumper under the Nano, in which case you would need to solder to the board for the TTL/PWM signal and then get power from the power supply.

Time to get the soldering iron out again... even their Mana CNC that has some pins going to headers doesn't make it any easier.
