4x8 Gantry Build...

[Apocalypse Fabrication]

My gantry beam hung over the edge of my side plates about 5/16”, so the reinforcing brackets would not work without shimming. Today I am going to bring home some washers and longer bolts to make this work correctly.


I am also going to make some cable carrier brackets. Why aren’t these included? Seems that every other bracket was there....
Since I didn’t have the cable carrier brackets made. We had to stop with the instructions at this point. I looked over at the bench with all the parts and wondered… “hrm, don’t these motors and z axis need to go on?” I scoured the instructions and found nothing about their mounting. The following pictures are just me guessing where things go and bolting them up loosely in case I got it wrong.

I was missing to the nyloc nuts for mounting the z axis. I stole some off of the side motors for right now.


The magnetic torch mount was pretty straight forward, just lined up the locating dowels and watch your fingers!

The motor for the z axis used the 4 black allen screws, the aluminum standoffs and the shaft connector (which looked like a rubber Lovejoy coupler, if you know what those are).


Loosen the allen binding screws and slip/force it on to the motor and the z axis screw.

Then install the black allen screws and standoffs.


The machining looked like the outside holes were a little thin… be careful on torqueing those down. Is there a reason why there couldn’t be an 1/8” more material there?


I really hope my instructions and pictures help others in the future. I will be sending my therapy bills to Matt@ Bulltear! :P
