The difference between the standard models (X4, X6, X8) and the "M" models (X4M, X6M, X8M), is the linear motion system they use.
The standard models (X4, X6, X8) utilize square profile linear rail, which offers excellent rigidity and is ideal for cutting harder materials like aluminum. The square profile linear rail ensures stability and precision during machining, making these models well-suited for demanding applications.
On the other hand, the "M" models (X4M, X6M, X8M) feature round chrome-plated and linear bearings. While these bearings provide don't offer the same level of rigidity as square profile linear rail, they can be quite a bit cheaper. As a result, the "M" models are not recommended for cutting harder materials like aluminum, as they may not provide the required stability and precision.
Out customers typically require the extra rigidity so for the purpose of these guides we will only discuss these models.
*-USB machines do NOT have a built in controller and require a separate computer running something like Mach3 to process your gcode. *EPL machines have a built in controller and do NOT require a separate computer or Mach3 connected to run your gcode. We personally recommend only the *-USB machines as Mach3 is more powerful then the controller in the EPL machines.
If you plan on cutting lots of metals/harder materials like aluminum we also recommend the X8-2200L-USB or X6-2200L-USB machines due to the upgraded 2.2Kw Spindle.
Most FRC teams are best suited with choosing the X8-2200L-USB with the X6-2200L-USB coming in as the second best due to the upgrade spindle and large work area.
If neither of the above apply to you, for example if you are primarily working with softer materials like plastics and woods any of the below machines are great options.
In the below tables the rows in blue text will be the most important specifications that most people will make their decisions on. You'll also notice that some are not covered, these machines we typically do not recommend for the above reasons.

Water-cooled spindles provide superior cooling efficiency for heavy-duty and continuous CNC machining, while air-cooled spindles are simpler to install and maintain but may be less suitable for prolonged and demanding operations. Water-cooled spindles also tend to be quieter.
