The LMS X2 also has a bigger table, with so much longer travel in all 3 axis that the total work envelope is DOUBLE the size of other X2 mills. It also comes with belt drive instead of the noisy/weak plastic gears on other X2 clones, and a 500w BLDC spindle motor with a tachometer output, instead of a 350w brushed motor.

My mini-mill Y-axis alignment required the bottom of the column to be pulled in toward the base, so the 3/8" outside bolts were tightened first, as evenly as possible to avoid any twist. Then the inside 7/16" bolts were screwed in just tight enough to eliminate any flex. If the required correction was the other way, the center bolts would …

The X2 mill is a popular entry-level machine for model engineers. It shares many features in common with the popular mini-lathes, and like them it can benefit from a number of relatively inexpensive and straightforward modifications that greatly increase its utility.

Run the cable through the unit - the loose end should exit through the hole between two black screws (as shown on the picture 5) 4. Mount the unit inside the column (securing all screws)

The massive headstock alone weighs more than the ENTIRE MILL that I use for jewelry does. You don't need that much of a spindle when an 1/8" mill is the tactical nuke of jewelers bits, and most work is done under .010" You do, however, need it to run much faster than an X2 spindle can handle.

The typical Sieg X2 mini-mill [HF 44991, Grizzly G8689, Micro-Mark & others] has a lot of backlash in the Z-axis.In my case it was .053-inches, which was almost a full turn of the fine-adjust knob. I heard that putting a shim behind the rack on the column would help by causing it to mesh tighter with the pinion gear in the head.
