If you have a Stepcraft CNC you know how easy it is to switch the spindle for another tool.

This alignment tool fits in place of the spindle and is the easiest alignment tool to print.

You've probably seen the others I have designed and made, they all use cheap laser pointer parts that all need to be aligned. This one uses the slightly more expensive lasers that is constructed differently and has the laser aligned much better, almost exactly co-axial. Try to get the smaller angle (90 degrees) but the 120 degree version works well. I used a cross but a dot will work as well.

Another laser cross

It does require slight alignment but it is very easy to do using the three #6 x 3/8" screws and once done never needs to be redone. If you don't want to use the screws then just use hotmelt, paper or some matchsticks.

The only less than perfect aspect is that it needs a power supply of 3 to 5V. I use a USB cable.

Post-Printing =============

The design has the holes threaded for #6 screws. It makes it easier to run a tap through before you assemble. Not critical but the screws will be tight if you don't - use some lubricant if you use the screws first.

The heads on my screws were 6.5mm and fit easily, if your heads are larger and don't fit then file them down by putting them in a drill or just cut them off and put slots in the threaded section to make your own set screws. They only protrude about 1mm.

File the z-seam off or the holder will jam in spots when in the spindle clamp.

Focus the cross at a distance near to what you will be using and then insert the laser into the holder and loosely tighten the screws to hold it upright.

Align the laser cross with the cross in the holder and by turning the holder in the spindle mount adjust the position of the centre of the cross so that it stays in the same spot on the CNC.

Once aligned and the screws are reasonably tight it needs no further adjustment. Glue it or leave it with the screws in.
