It is relying on the M106 & 107 commands and a value form 0 to 255 from this example.

Thank you

Thanks for the tip. Did some mods to my setup that is helping with this issue. 1" angle iron on the sled give extra wieght. Also they allow for work on smaller projects without having to build up around so sled doesn’t tip off. Sled is also more stable as far as minor tipping when changing directions that shows up with the fine cut of laser.

Slotted the mounting ring brackets to adjust center of gravity without router.

if the sled tips as you change direction, that means that the ring/linkage isn’t
actually centered on the bit/laser

I found that if the plywood is cupped slightly it is more pronounced. Working with a router not as noticeable as it is with a laser. This setup helped substantially.

Are there any 30 or 40w lasers that dont’ need a huge tube and water cooling perhaps heatsink with air cooling? It would be amazing if something that small existed so it could be mounted on the sled. cutting 1/8 acrylic would be cool.

I am very interested in this once I can teach my maslow to cut squares.

Does grbl work with maslow shield or does one need to get the duo shield?

28

plain grbl can’t drive the maslow, the fork that does is designed to run on the
duo. the original shield won’t attach to the duo, but you can have some short
wires connecting the two to fix that (and add the eeprom that you need)

I’m just wondering what you have to do to get power from the aux port. Also wondering about the commands for turning laser on and off. I have bought a 15w laser off eBay and intent on using it on my maslow but need to know how it go about it
Cheers

well not sure if you are around Dean, but I have an extra Grlb Due board I can mail you. I woudl love to get laser capabilities added to maslow at a low price,and have it be open sourced. Seems like the “open source” foundation is no longer being supported by vendors.
