Rotary Attachment in Laser Engraving Machines

 It is important to note that there is a lot of different rotary designs out there, and getting the right one to most effectively work for your intended application is very important. Simply googling "rotary device for my laser", you will be showing a variety of rotary devices ranging in size, price and connection type. For this reason, the intention of this post is to provide you with the understanding that there are two main types of stepper motors equipped with the rotary attachment. This will help you decide which rotary best fits on your system. 

1. Motor type

A two phase motor or three phase motor can be found equipped in a rotary attachment. This will imply that you will need a two phase driver or three phase driver to drive the rotary and subsequently a 4-prong or 3-prong connection to have the laser connect to it.  Usually your laser could have a rotary connection already built-in and knowing the type of connection already in place can faciliate setup and your search.

2. Price

Once you know the type of motor you will need, look at the rotary choices. You can go with the higher priced $1000+ units or simply decide to go with the starter kit ones. We offer a small, and medium size roller rotary type and one large chuck rotary type for your convenience. Choosing the price that meets your needs is important, the magic happens in the understanding in the use of the rotary attachment, the price complements the support only. 

3. Size

If the rotary attachment form factor you found online is perfect for your machine but it comes only with different motor connection than the one your machine is built-in just know that you can choose to either change the motor and gear size to meet your machine or change the driver and the connection to meet your rotary attachment. Most DSP controllers work with 2-phase and 3-phase drivers. 

Example: 

The Lightobject Ranger is a perfect desktop machine, it comes with 4-prong connection built-in to easy connect a 2-phase rotary. The problem many users have brought to my attention is that most rotary attachments online are midsize and putting it into the machine to do tumblers reduces a size you can work with given to the loss of z space it is lost. If this is the case, I tell my customer to look into our mini-rotary which is a low profile 2-phase attachment. This rotary attachment will work with the 4-prong connection and all the customer have to do is wire the plug to it. It helps that the rotary is price, sized and motor type matches comfortably the needs of the customer.  

In conclusion, most laser machines are not proprietary and the type of rotary you choose to use only depends on the above. Don't get think that you are stuck with one type of rotary attachment size.
