Edmond's Buildlog.net Laser Build in SA

Postby edmond22 » Tue Mar 01, 2011 7:58 pm

I have started sourcing and fabricating parts for my buildup of the Buildlog.net first version laser cutter.
Planning to run Lightobjects DSP controller on it
This build will hopefully be finished at the most in 6 months time as the budget is limited.
So far all the 6mm acrylic parts have been cut, next is to purchase the bearings and fasteners then the aluminium extrusions are next on the list
I have found a local supplier of the V track but its expensive at $57/m they also sell the v wheels but they are also pricey at $40 a v wheel

Got a friend who's going to make me the small v wheels so thats one less thing to worry about.
Still don't know what to do about the v track might try and make it from acrylic or some other hard plastic, the proper steel one is just too expensive here

V wheels are done, I cut them from 8mm PVC on the CNC Router at work and then had a friend put the groove in on a lathe, I made 20 just in case, also got the bearings for them

I cut and glued the Z axis carriage together today, cut it from 6mm Satin Ice Acrylic because its a offcut I had.

Extrusions will be ordered in a few weeks time along with the tube and power supply.
I haven't decided on the motors or drivers yet.[

I found someone here in Cape Town, SA selling used Nema 17 stepper motors for the equivalent of $4 im gonna check if he has ones with similar specs as the ones the buildlog.net 1.0 laser requires.

Since I can't find a local supplier of the MXL timing pulleys, I have been toying around the thought of making my own.
Here's one I made today, using the iges file from stock drive I still need to drill and thread the hub for the M3 grubscrews but otherwise it came out quite nice.
I also have a 1910mm length of 20mm wide MXL open ended belt that I somehow need to cut down to 6mm wide, if I can figure out a way I should have enough belting to do the X and Y axis.

Nice job!
How did you make the pulley?

Agreed! Looks great. I'm assuming you did this on a mill - what size bit did you use? Feeds?

Pretty cool!

I actually laser cut the orange cogged part and the front flange and then cut the hubs on a cnc router, it sure is handy having access to a laser cutter at work.
I then line the parts up by using a dowel pin and then glue them together using acrylic adhesive.
They are made from 6mm and 1.5mm acrylic.
They might not work but they are worth a try and they cost me nothing to make.
I'm going to finish assembling them all tonight.

Several of the bearings are actually idlers and don't need teeth. That will save you some time.
