EleksMaker Mana SE / New mana se version 3.1
« on: August 22, 2018, 08:31:03 PM »

Looks like the new mana has pin outs for d9 and d10 for limit switches
12 v for a fan
5 v for 5 v things
ground so your head doesnt get too big
and several other pin outs. 
Might just be the way to go for easy mods.  I'll get one and let you know what I think.

Other Software / Lightburn
« on: January 14, 2018, 09:47:42 AM »
There is a new software which someone is trying out on the facebook eleksmaker group.

I have downloaded the full feature 30 day trial.  It does not come with firmware so you either need to know how to modify your firmware yourself or use zax's T2 firmware before going to laserburn.  It does not do rotary.  It is $30 for grbl license (which is for 2 pcs and any number of lasers) or $80 if you need to control co2 laser.

It does use home switches very well.  I definitely like the fit/finish and feel of the software.  It works well with dxf and svg files.  It can also easily adjust power and speed of specific lines.  All in all I would say it appears to be a nice software but for me cant replace t2 due to the lack of grbl firmware support and lack of rotary support. 

Engraving / ac electro etching
« on: December 03, 2017, 12:57:17 AM »
So if you are electro etching.  DC removes metal and AC makes it black.  Ideally you want to do both.  I used an old ac to dc converter from goodwill to do my dc etching and it works great.  Etching ac at 110 is a bit dicey.  Does anyone know a common household item that steps down 110 ac to like 30 volts ac?

T2 Engraving / Engraving on a slope
« on: November 10, 2017, 01:59:29 PM »
Ok so say we had a set slope and we know it goes from 1mm to 10mm and the object is 9mm long.  so every 1 mm we move we need to also move 1mm up when we are going left.  When the laser comes back to the right in needs to move down 1mm for each mm right.  Is this something that can be done using the cnc modes and a z axis?  I know the cnc modes will let you drop the laser say 1 mm every revolution when repeating a pattern but can it just smoothly make the laser follow a slope too?

Video Tutorials/Information / Laser youtube channel

Ok I started a new laser engraving channel because I dont want to mix it with my personal videos.  here are the videos links.  I will be moving all my other videos here this week and reworking them to fix the broken ones.

Projects / Commemorative Football ticket

This was commissioned by a friend for a vikings fan's first game. 

Hand painted and sealed with a spray polyurethane.  took like 5 days for the dang poly to fully dry

Projects / Portraits
« on: October 31, 2017, 01:45:56 PM »
so I finally did some portraits on live edge basswood (from michaels big surprise there).  It took a lot of messing around in gimp  to get the photo where I wanted it.  Engraved in greyscale with the 1.6watt laser head.  speed 2500 resolution .1.  0-255

On the one with the beach scene I lost the detail in the clouds so maybe 0 wasnt the best place to start my power setting.  They still turned out amazing.  I really like how the rock pops next to the train.  In person it looks 3d.  I think that was due to the cartoon filter I applied as was suggested on one of these threads. 

I am not sure how to prevent the knots from burning though.  They kinda cause some unsightly issues.

These were both commissioned pieces.  I didnt charge much because I was fairly sure I was going to ruin them!  She actually gave me 2 pieces of wood and 2 photos and asked for 1 picture on wood.  I surprised her and didnt ruin either piece in testing so I gave her both pictures and both pieces back. 

Assembly Help / CNC Kitchen live stream
« on: October 28, 2017, 12:53:09 PM »
CNC Kitchen did a live stream of setting up the eleksmaker and running it this morning.  I gave him some help.  I almost forgot to have him change his windows regional settings.  Man if he had failed that could have been bad for our community I think.  We got him going and burning things which I think is good for our community.  It was an accurate build.  It showed the problems that many new people run into and we got him fixed in minutes instead of the hours many of us had to dedicate to the problems.  Check it out if you get a chance. or if you need to build a new machine.

Projects / Yeti Mug with a 3d printed handle
« on: October 27, 2017, 09:30:45 PM »
a commissioned yeti mug for a friend on a swat team with a 3d printed AR handle.  I'll post the design on thingiverse this week.  The engraving doesnt stand out well on the green.  I am gonna try to do another one and electro engrave after to see if it helps with visibility.

burned at 50mm/min.  took forever and a day (18 hours) used the rotary set at 86mm diameter.  Used alcohol to remove the burned powder coating.

Laser Accessories / Extendable legs
« on: September 24, 2017, 11:10:52 AM »
So my rotary axis does not fit under my gantry.  (I didnt think it would) I need to prop up the legs to get the clearance I need.  I was looking on thingiverse for some stackable risers so I could prop up each leg the same amount but I cant find anything that would work.  Then I thought about redesigning the print in place jack to have a laser engraver leg on it so I can just jack it up to the appropriate height.   I cant decide if that would be better or just stackable risers.
