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.

STL / X carriage tensioner for new eleksmaker with openbuild wheels
« on: August 13, 2017, 02:21:25 PM »
I ended up making my own since the existing one on thingiverse is for the old smaller wheels

Trouble Shooting / wheels not rolling smoothly
« on: August 09, 2017, 08:34:06 PM »
so I have a new a3.  I didnt notice any problems until i went to produce some burns this weekend and noticed some shadowing.  I checked everything expecting a belt issue causing backlash.  So far I am yet to figure it out.  There is a slight clunky feeling with all the wheels on the x axis.  I tried to wear them in by making it do a huge square for a whole day with the laser off.  That didnt help.  I tried each wheel and no individual wheel has any clunk to it.  I tried just the top two wheels rolled on the cross bar and nothing.  smooth as butter.  same with the bottom wheels and the bottom bar.  But when I put it all together I get the clunk.  I thought maybe it was a spacer off causing the wheels to be misaligned but when put slight pressure in any direction it still clunks. 

The last thing I can think of is something is up with the acrylic being not perfectly aligned although I doubt it.  I'm gonna try some stl's from thingiverse for the x carriage and see if that changes anything.

Laser Accessories / rotary axis troublshooting
« on: July 31, 2017, 04:56:14 PM »
Ok so I got my rotary axis working just fine.  Problem is that my glass is walking around on the axis.  when it was turning one way it seemed fine.  Then when it would go the other way it would start moving backward till it was going to fall off the rollers.  Any thoughts on how to make it stay put?

Also I noticed the tolerances for the stepper were wrong. and the second roller holders were taller than the motor rollers.  I had to fix the stls and I will post them today.

Trouble Shooting / I cant open this dxf
« on: July 11, 2017, 08:51:09 AM »
can you guys try your softwares and tell me which one will open this dxf?  Fusion and inkscape dont work but T2 opens it fine.  I want to extrude it up and make an stl but step one is opening it!  I dont want to spend all day downloading software that doesnt work and I know y'all can give me a hand.

Trouble Shooting / extra resistance at the ends
« on: July 09, 2017, 11:12:08 AM »
Ok so I put my new a3 together and I have an odd problem

The last 2 inches of the y axis act as though there is extra resistance.  It happens on both ends.  If I keep the gantry away from the ends it works just fine.  If I go out to the ends it chatters, misses steps, and acts up.  I increased the voltage to the y axis.  No luck.  I loosened the belts.  No luck.  I tightened the belts. No luck. The gantry rolls fine but powered movement still has issues on the end so now I'm at a loss.

Any ideas?

STL / better belt tensioner
« on: June 30, 2017, 09:46:27 AM »
So this belt tensioner is designed to be used outside the rails.  It will essentially add a couple cm of engraveable space.  The problem is I have no idea where I got it.  I thought I got it here but I cant find the thread.  Any one remember this thing and who designed it? I remember ralph had some too that he was selling and I cant find that thread either.  If someone finds it please let me know.
