I just purchased a milling machine that was in parts. The controller is the CS-LABS CSMIO/IP-S along with the expansion unit for the hand remote. However what I don’t understand is the need to the Geckodrive G540 unit. From the little I have read all the G540 controls is the E-stop. There is also a bit about having to download firmware for the g540 to function. Do I just download this the same as the firmware for the CSMIO/IP-S and or do I place the G540 firmware in the mach3 folder like you would the license.
