Thanks, for your response. I did check the jog distance. It is incorrect.
Here’s the feedback that I received on line to correct the problem. I will try these solutions. Any other suggestions? Thank you Jack.
Altmill wrong jog distance
If your AltMill is jogging the incorrect distance, the issue is typically caused by incorrect motor DIP switch settings, blank firmware/jogging preset values in gSender, or physical slippage. [1]
Check the Motor DIP Switches [1]
If your machine is moving the wrong distance constantly (e.g., exactly double or half of what you command), your driver board’s DIP switches are likely set incorrectly. Power off your controller and verify the switches on each motor driver: [1, 2, 3, 4]
• X and Y Axis Motors: Switches 1 through 5 should be set to OFF, OFF, OFF, ON, ON.
• Z Axis Motor: Switches 1 through 5 should be set to OFF, OFF, ON, ON, ON. [1]
Verify gSender Jogging Presets & Firmware [1]
Incorrect distances in software can happen if the step values were accidentally erased or changed. [1, 2]
• Open the Config or Firmware Tool in gSender.
• Go to the Jogging Presets and ensure the values aren’t blank. Click Reset to Default to restore the factory settings. [1, 2]
