Hey all,

I am new on here and have a question regarding changing out my 2006 (year) Vexta (model ASM911AA) stepper motors (DC 2.56V, 2.1A) for new servo motors. I am running a 5x8 table w/ a HSD 4kw ER25 spindle which almost exclusively cuts wood. I have had GREAT luck w/ the steppers but I am itching to increase my CNC output by improving the motors. Any suggestions or recommendations about brands and change-out pit falls?

BTW, I am also getting a new "good enough" 4kw ER25 spindle/VFD ($650 all in) so I can have my HSD 4kw ER25 rebuilt ($1,200). Been considering the Chinese manufacturer Changzhou Hua Jiang Electric Co. who seems to own the Alibaba, AliExpess and Ebay channels in the low-mid tier spindles. Feel free to share any thoughts about spindle/VFD upgrade as well.
