Z Axis / Re: Adjustable focus rather than a moving Z-Axis?

>If we get enough response we could start a z-axis thread (assuming Ralph hasn't already).

We already have one: http://benboxlaser.us/index.php/board,70.0.html

>and for adjusting focus during the run when using multiple passes?

FYI -- BCL can generate g-code to support a Z Axis if you have one installed on your laser machine.

I understand...I will put this request on the to do list for you.

UPDATE: See attachment. I've added the checkbox but it does nothing at this time. I will be adding the code to make it work when checked.

I use QCAD and LibreCAD...both will save a dxf file in a format newer than year 2000 and thus avoid that error. I can't get around that error because the library I use for dxf files has that limitation so I'm stuck with it myself!

Inches G20 and MM G21 are also working. This was a problem early on in my testing.

Arcs and Circles G2/G3 are also now working.

The Marlin firmware I used is not the factory laserBot firmware, so users will have to flash this custom firmware in order to be able to use BCL with their laserBot machines.

See attachment showing the new 'welcome messages' as there are two with this Marlin firmware.

The FA stands for 'flipped axis' so the lower left corner is now the 0,0 reference.

The BL stands for 'boot loader' as this version of the Marlin firmware has the boot loader code in it.

makeBlock has given me a link to their factory laserBot firmware that I will include as part of the new 1.8.4 install in case anyone wants to use their mLaser software, they will need to re-flash.

>what happens exactly if the head of the laser is turned ?

That's how you focus the laser beam.

Using BCL, burn a line, turn the focusing knob a bit, burn a line and see if the line is thinner or thicker. If thinner, turn it again in the same direction and burn another line. Repeat until you get the thinnest line. Now you're in focus.

All you have to do with an pre-2000 dxf file is open it in your CAD software and do a save as to a newer format and then BCL will be able to use it.

Yes, I can do that, however, if you can't see the lines running left/right, how will you see them running up/down? I don't understand why direction would make any difference?

The multiple line problem has been resolved!!

Simon, a member on the makeBlock support forum, ran a test g-code file I sent to him and he sent back the results. He was using different software, but I was able to analyze his results and figure out what was needed to make this work with BCL.

I'm happy to now report that all known issues are resolved and my initial laserBot full scale testing has been 100% successful using BCL...!!!

The only remaining issue is I have to figure out the right flash string so BCL can do the Marlin flash itself and not have the users use XLoader.

Things are looking up!

 :D

Excellent project...!!!

I don't think you can adjust the laser beam shape.

If your burning on wood AND the grain is running left/right (my suggestion) then the laser speed for left/right should be faster than it is for up/down...to get a square that all four burn lines look the same.

Important: get one of the directions burning the way to you want, say start with left/right (speed and laser power %). Then work on the other direction (up/down) and ONLY change the speed to get the same burn look. Do NOT change the power on the second direction!

Once you adjust the speed for up/down to give you a burn line that looks like the left/right, you're done with a square.

Use those same settings for the triangle with the 45 degree line. Look at the 45 degree line and adjust the '45 Degree Feedrate' spin button to get the % that makes that line look the same. It defaults to 50% so play with its settings to get that line like the up/down and left/right.

Now those settings will work perfectly for the Circle shape test and the rounded rectangle shape test.

You should work all four shapes from top to bottom. Once you get the 45 degree shape right, the other three should be the same and you can just test them to make sure.

All of this for just one laser tool. Do this procedure for all of your laser tools, depending on what kind of burn you want.

For cutting, I'd get all the lines looking the same for one pass initially, set to 100% and then after I've adjusted the speeds and all the lines are looking the same, NOW you can set your passes and test how many passes you need to cut through.

Still waiting for some answers on why multiple lines won't feed into the MegaPi controller board.

Paul has been hard at work on adding image capabilities to BCL.

Attachment shows his work in progress.

Coming soon...!!!
