To adjust the height of the pulley to match the one on the motor, you can shim it with washers. You’ll need to drill a couple more holes in your slider track, too. A belt pulley is attached to the spindle, but it needs to be recessed or it interferes with the slider carriage.Ī flat piece of metal is belt and drilled to mount the pulley at the other end of the slider. Max also cut a larger hole for the motor’s spindle. Then, peel off the tape in one big chunk, stick it onto the slider and use a centre punch to mark the holes for drilling. Simple place it around the top of the motor and mark the holes with a pencil. the easiest way to do this is with masking tape. Once you’ve figured out which end the motor’s going on, the first step is to measure & mark the positions of the holes to mount it to the slider. But you can find clones for as low as $5 if you look hard enough. The Arduino Micro listed, for example is $25. And you can probably pick them up for a lot less if you shop around. ![]() In theory you only need one, but its easier to troubleshoot if you have multiple.A 12V stepper motorA centre punchA metal saw or angle grinderA drill press or handheld drillĪssuming you already have the tools, or can at least borrow some, the total cost for all the components specific to this project is only about $75. ![]() It is an investment, but it pays out in the long run.A4988 stepper driver.

The slider is modified using a stepper motor, a belt drive, and a custom made (but simple) bracket. It just takes a little planning and a few tools. It takes a little machining and a few parts, but it’s fairly straightforward. ![]() This video from Max Maker demonstrates how to turn a very inexpensive slider into a more practical and useful one. But it’s really not that difficult or expensive to convert a standard manual slider into a motorised one. Without motors, they’ve dropped to ridiculously low prices. Despite the proliferation of sliders, motorised ones are still quite expensive.
