Spindle Setup
« on: December 13, 2020, 05:02:27 PM »
Hi

I am setting up my machine I built and am having issues turning the spindle on. When I press "Spindle CW/Stop" the spindle will turn on for a few seconds and then turn off and the Enable starts flashing. It has this in the log file:

API: mcSpindleSetDirection(inst = 0, dir = 1) (unknown caller)

I have the following parts/machine/settings

Spindle, 2.2kw liquid cooled amazon special with a
Inverter: Huanyang inverter 220VAC Single Phase
Ethernet Smoothstepper with C11G breakoutboard

Let me know if I need to post settings

Disable your limit switches and see if the spindle runs better,  if so it may be noise on the limit switches.
