I am converting a Sieg X2D mini mill to CNC using the Heavy Metal kit. I have a SainSmart 4 axis kit with Nema 23 steppers and ST04045-A1 drivers and an STB4100 Mach3 USB Motion Card. I purchased the license for Mach3 a while ago. It is all running under Windows 10. I am bench testing the electronics before installing on the mill.
I am struggling to get the continuous jog function to continuously show movement on the DRO by using the keyboard. If I hold the movement key down, the motors turn for a short time (maybe 1 revolution) and then stop. If I release the direction key and push and hold again, it will move/indicate the same distance.
Changing the velocity setting in Motor Tuning will affect the amount the stepper turns and the distance the DRO indicates. If I use the onboard pendent keys, it works as it should (motors turn as long as I hold the direction key down). What am I missing the get the keyboard to work properly?
