Banggood Z axis to eleksmaker laser mount
« on: May 13, 2017, 09:58:13 AM »
I added 9 bolts to this guy to ensure it stayed put, annoying part is the z axis mount is wider than the aluminium laser extrusion but the side screws are close to the edge.
I bought a bunch of 3mm brass inserts, the holes are 3.8mm to melt these inserts into, the middle 3 are inserted deep and from the rear (no dirty jokes thanks).
The edge 6 are shallow as any deeper they interfere with the edge of the extrusion.
So you need 9 inserts, 6 x 3mm x 5 bolts and 3 x 3mm x 10, I dab at them with an iron till they start to fall into the hoke then screw a long bolt in with a few threads and locate it square.

btw, I noticed doing this that the screw has a spring loaded antibacklash mechanism on the bolt, will help it hold pisition with motor off and will increase accuracy to whatever end play the motor bearings have, probably repeatable to hundredths of a millimeter.

edit: while I had it open I made a second version that has simple 2.5mm holes instead of the larger holes for bushes. So this one should just enable anyone to wind a 3mm bolt into the hole and does not need the bushes, with 9 bolts and no major forces on them it should hold just fine.
Also extended the side holes deeper though they may interfere with the aluminium.

I wondered if it would be noisier mounted, not too bad.
So here is a little vid showing the mount in place and operation.

sorry if this is a silly question but how do you control it? Off the eleks board?

I added an extra stepper driver to the eleks board, somewhere on here is a thread documenting it with pictures n stuff.

Found it, have a lok at the 28byj-48 motor thread for more detail but the imgur album should give you most info on whether to tackle it or not.

not sure I understand, you are adding an extra stepper motor driver onto the eleks board direclty to specific plases?

Not sure I understand, random places will not work as well.
Grbl supports a z axis standard, you just need to connect to it.

looks like a Z axis was added to the MANA SE.


Stone, have you added a cutter to your Z axis? How is the clearance?

what sort of 'cutter' and what clearance ? I mean it depends on where e bed is, where you decide to bolt it and how big everything is.
did you see the video a few posts up.

By clearance, I should have clarified, from your video it appears the bottom of the Z axis assembly is about 5cm above the board that has the grid on it. If the waste board does not move up and down, then it would seem that Z axis use is limited.

As for cutter, have you added a dremel tool, kress mill router, or dewalt router and experimented with the sturdiness of the Z axis?

I currently just want to drill printed circuit boards so really I could do it with 2mm of movement, howver changing drills it helps to have the additional 48mm of lift above the base board, so it is currently 'optimised' for above board clearance. You can move the slide up in the X carriage by another 20mm or so if I needed to work an inch above the base.

However light milling is always going to be worth a shot, so I currently have a resharpened broken 3mm end mill in there and a piece if test balsa wood in place.

The banggood spindle motor bolts straight on (I reviewed it a few days ago roughly, yet to do performance tests) and at full lift the bottom of a small tool is pretty much level with the base if the axis so you pretty much have the full 50mm to work with if you had long enough small tools.

I still have to revisit and add some filtering as spindle noise is causing the Z to add steps.
But to give you an idea ..
