Manual indicates this is a ground fault. Disconnected from AC, called and left a message at 951.677.7755 and sent a message via the email form on heliopower.com.

The manual indicates that the yellow and red leds being on is a ground fault and fails to mention that all is well if the green light is also on. After re-connecting to AC, all is well, meter turning backwards again. Thanks to HelioPower for setting me right.

That sort of functionality is normally built into the motion controller, like the Marlin, or Teacup, or GRBL firmware on an Arduino, or in the Mach3 or LinuxCNC software on a PC. You should ask those people if they support that function.' at: '' j2sip@yahoo.com asks: " Hello

Does your driver include any input for router stop or speed control( thru appropriate means, of course).

Thank you." |Delete 'P-' before: '' but after: 'Torque for more' at: '' sos@alum.mit.edu asks:

I'm building a 24x30" wood router. It will have plastic linear bearings (8020 style), 5 start 10tpi acme screws. Motor torque requirements come out below 100 oz-in for several methods, including the one here. Why do people use 300 oz-in motors on machines this size? I realize torque drops with speed.
I like the looks of your 4A driver.
