Z Axis / Eleksmaker made good on their promise
« on: April 14, 2017, 12:40:30 PM »
Eleksmaker's Z told me they were working on a z axis for us.  It had been a few months and I didnt expect much if they actually did produce something (sorry for my lack of faith Z).  At best, I expected what bill made (not that what he made is bad, in fact that was the best I had seen yet)  Yesterday Eleksmaker revealed the fruit of its looms (fruit of its labor??!? I prefer looms).  For those of you that dont monitor their forum here it is.  Notice it has a fine tune adjustment knob at the top.  This would make your laser a 3 axis machine so an upgrade to a Mana 3 axis would be required.  I'll update when bangoood lists it for sale!  I know I want one with a new 7watt!!!

Assembly / Prusa I3 Mk2s
« on: April 08, 2017, 07:40:53 PM »
Ok so my prusa is finally printing away. 

Here are some things I learned putting it together. 

1. Pay them to put it together for you (suck it up its worth it.)
2. Ok you didnt do number 1 and I didnt either.  So we are both stupid and gluttons for punishment.
3. Dont put it together during a storm when your microwave dependent internet will go down constantly and you cant look at the good instructions online.
4.  The motors are labeled because they know im dumb (see #2).  Put the right motor in the right place.
5.  If you dont put the motor in the right place at least wire the y axis to the y and the x axis to the x.
6.  If you wire x to y and also put the limit switch for x to y so they match, the machines auto calibration wont realize you made a mistake.
7. If you dont do 4-6 your probe cant find the little stupid dots and it will keep running into the print surface and you will get angry.
8.  Take your time.
9.  Take lots of sandwich breaks
10.  Dont zip tie anything(except the stuff that is held on no other way) until you are done

Fyi first print - marvin

T2 Engraving / Tutorial videos not sanctioned by Zax
« on: April 05, 2017, 10:27:22 PM »
Alright so making a quick video is easier sometimes than me explaining certain T2 and inkscape things.  I am a visual learner so this helps me.  I am gonna upload a some tutorials when I see a question I think might benefit from it.  This thread will be a repository for the links to explain certain things.  I will keep it up to date with my tutorials.  Hopefully I'll buy a better video editing software to do screen capture soon.  Right now its cell cam.

What to do after installing T2 Laser

(this one has at least 2 glaring errors. 1 I did not go over how to move the jumper. 2 I did not go over how to install the driver.  Also its all glitchy.  Premier didnt like my screen capture so I will rerecord when I sort out my editing woes)

Spare Parts Sources / stepper motor wires
« on: January 28, 2017, 05:53:49 PM »
https://www.amazon.com/gp/product/B01G2WMRLE/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1

bought these wires.  plenty long for A5 however I used them on the y axis and they reversed the stepper motor direction (they are not wired the same as stock ones).  The old and new one were working against each other so I replaced both.  Luckily I had bought 2.

Assembly Help / Wiring home switches
« on: January 21, 2017, 11:41:20 AM »
Ok so I think I have read every topic we have on homing switches.  I am super afraid of letting out any of my magic smoke so soldering on my laser toy is scary.  I know they need to be put in parallel on the D9 pin.  I saw how gallant @ggallant571  (I think) wired his on the backside (Picture below) but I will screw that up for sure.  Then I saw how @Johnb63303 did it by soldering on new female headers on his nano.  I like that option but that is wayyyyy more soldering for me to screw up.  Does anyone else have any diy easy wiring solution for home switches?

painted, dried, taped, engraved, nylon brush, black paint, dry, remove tape. Then I hand painted the minecraft guy.

 You will see on Rylees some tape goo still on it.  I'll clean it up when its fully dry tomorrow.

Projects / Basswood
« on: January 06, 2017, 06:22:55 PM »
So we were at michael's (you guys know how I love Michael's) and my girlfriend saw a piece of basswood that they were showing you could use for woodburning for a sign.  She says "honey, could you do something like that?"  to which I replied, "Of course I can! I have the hand of Zeus in my garage!"  So she bought it and made me make a sign for her mothers house.... I dont know if I won or lost.  Here are the results

resolution: .1
speed: 750
power: 255
Taped
Air assist
polyurethane spray to finish

Trouble Shooting / Broken stepper motor wire
« on: December 22, 2016, 01:11:10 AM »
I had a problem but I solved it.  just thought id post for others. 

My Y axis motors werent moving smooth.  I couldnt see why.  I checked everything was tight but not too tight, but it was still rough.  I disconnected the motors to check the connections and noticed my white wire on the +x side was broken.  A little solder and it was back to its old self.  Dont know how i broke just the one wire but I'm glad I found it quickly.

General Discussion / DXF SVG JPG PNG Depository
« on: November 01, 2016, 10:49:28 AM »
Hey guys.  So I was talking to ralph about setting up a topic to deposit good usable DXF SVG and picture files that we know will work well with our systems.  For instance, I have a good DXF i found online for a grid with letters.  I used it on some mdf to create my support piece inside the gantry so i know how big I can engrave and of course helps me line stuff up straight.  The problem is we dont have enough bandwidth here to support a file center such as what I'm proposing.  Does anybody know of a good free file hosting site we could link a topic to so we can share files that work?

Laser Accessories / Laser shield
« on: October 25, 2016, 10:02:18 PM »
So while I wait for things to burn I sit at my computer working on the next inkscape or t2 settings.  The laser is burning a few feet to my right so I have to keep my cool Chinese glasses on my head so that the laser doesnt burn a hole in the side of my right eyeball.  This is getting bothersome.  So I want to put up a small acrylic wall to block the light from my blue diode.  I dont want to just build a case because I may be working on some large pieces and I want the option to just pick up the laser and put it on it. then move it over a foot and do the next section. 

My question is this.  What color acrylic would provide the best protection for my eyeball.  Should I just go with the green that glasses are made of or is there a better color for protection.   Oh and by wall I mean like a 1' by 1' piece of vertical acrylic.
