Mach3 and G-Rex / Help Please!!! X and Y axis move in one direction
« on: December 24, 2022, 04:43:48 PM »
Hi guys,
I am currently trying to get my Harbor Freight Mini Mill converted to CNC. I am using Mach3 as my software on a Win7 PC. I have the Z axis moving smooth yet X and Y only move in one direction. I feel its a configuration issue because, I swapped connections between drivers and the same two axis aren't working. I also check to see if there's any breaks in the wire by checking continuity. I have everything wired according to the schematics and instructions. I even swapped the motors around to see if the issue was motor related and that all worked all fine on the Z axis connector. I removed the breakaway connector on the drivers and installed them to the Z axis driver and they worked as well. I mean it could very well be the drivers for X and Y that are defective. But would like to see if my configurations are wrong before I start ordering parts. I get movement in one direction on the X and Y.
I configured my motors as follow on Mach 3:
Port Setup & Axis Selection:
X Axis - Enabled Checked - Step Pin# 2 - Dir Pin #3 - Dir LowAction Checked - StepLowAction Checked - Step Port 1 - Dir Port 1
Y Axis - Enabled Checked - Step Pin# 2 - Dir Pin #3 - Dir LowAction Checked - StepLowAction Checked - Step Port 1 - Dir Port 1
Z Axis - Enabled Checked - Step Pin# 2 - Dir Pin #3 - Dir LowAction Checked - StepLowAction Checked - Step Port 1 - Dir Port 1
Using these components:
(3) KL23H286-20-8B Stepper Motors
(3) DM556 Drivers
C10 Breakout Board
