Well it is finally done!!! (Except for the table material which has been ordered)
- The laser in all of its glory.
This is a picture of the back panel with the air assist quick connect. Thanks Bart for the back panel without the grommet holes it makes the laser look much classier. (Bart you weren't joking about having no extra room in the crate, it was very nicely packed and I didn't have a single imperfection on any of the skins.)
- The rear panel with air assist.
Note: The label in this image is wrong do not set the steppers to 4 for 1/8th stepping set them to 3 (The motors do weird things).
I cut the corner out of the rear skin and mounted the radiator to it using 2.5" screws and some aluminum tubing as spacers. I also tested the water temp. to see how cool it kept the laser wanting to make sure two fans was enough. I fired the laser on full for a 5 minutes and the water temp. only made it to 29C and dropped back to room temp after a few minutes. So I am pretty sure 2 120cm fans is more than enough.
- The radiator mount and the exhaust port.
I wanted the radiator to be able to removed so that I could move it around to bleed air out of the system and make it so that I did not have to disconnect the tubes at any point. FYI, those are coils of silver in the distilled water, they are suppose to kill some bacteria, viruses, algae and fungi in the water.
- The radiator access panel removed.
Here is a picture of the final liquid cooling system from the inside.
- The liquid cooling system tube routing.
I replaced the y axis motor shafts and shaft couplers. I had a bit of wobbling in the shafts so I decided to order a replacement. I bought the shaft from mcmaster carr and the couplers came from ebay (search 5mmx6.35mm flexible coupler). The y axis motion feels smoother after the conversion.
- The new shaft couplers and shaft.
I am uploading another hundred pictures to the library now so take a look if you want more detailed pictures.
