Vertical alignment is critical for cutting. If you are happy with your current setup you might want to score some lines in the plastic as aids in aligning the new module.

That would be a great resource to have posted in the sticky section.

If you have "standard" gcode such as GRBL you can use a terminal emulator program to enter commands. The commands are all ascii. Using:

  G01 X10 Y20 F300

should move the carriage to location 10,20mm at a speed of 300 mm/min

  M03 S3

Should enable the laser and turn it on with a relatively low power but visible power. The generic command set is available online.

General Discussion / Painters Tape
« on: February 16, 2017, 10:07:44 PM »
I purchased roll of Scotch blue painters tape in the 72mm (2.83 inch) width at Home Depot. Is there a magic formula for changing the laser intensity while etching? Do you etch twice, once for the tape and again for the wood?

If I understand correctly you need to enlarge the holes in the plastic housing to insert the eccentrics.

Should be in the kit. Mine came with 2 different lengths. One for wheels and another for laser mounting plate.

On a side note, when I turn the lens the spot moves on the work. Does this affect the vertical orientation?

At some point the technology driven laser burning needs to transition into art. This is where I fall flat on my face and use this forum to get suggestions and techniques. So far it is working nicely. My stash of raw materials - plastic, wood, stone - along with brushes, paints, stains, masking tapes is growing each week. I am currently engrossed in making frames for etchings.

T2 Engraving / Re: How to engrave small text with high quality?
« on: February 14, 2017, 08:39:00 PM »
Attached is a file of the alphabet in Sans 1.0mm font. I etched on basswood with 5.5W machine. The text is readable but not great under a magnifying glass. Used speed 900 and power 16 out of 256. Tried at 300mm/min but the stop/starts made for a jerky head motion. I did not spend any great effort on focusing but suspect it would be better with a lighter power laser with better focusing characteristics. What were you expecting?

pawpawpaw85 has been quite quiet lately. I have been holding off building a new machine till his results have been published.

While eccentrics are readily available I think a spring loaded mechanism would be better.

Given that, my next frame is going to be round bar with linear bearings.
