Machine is non functional.
Usage
Due to the ease by which this tool can be damaged it requires supervision to use. Contact the metalshop team via discord and arrange.
The following document provides guidance on how to create a toolpath in Fusion 360 and use it on HILDI.
Guidelines
Please note these general guidelines:
- There is a one shot oiler in the cabinet under the control box. Use the plunger occasionally.
- Tooling:
- ALWAYS assume the tool offsets are wrong unless you have just set them.
- Tool changes need to be done manually.
- The probe is always tool 1.
- When you turn off main power the spindle may slowly drop if the stepper motor does not have enough holding power. This is OK.
- If you use the small mill vice there can be interference (collision) issues with the front door. It is best to mount the vice on the right hand half of the table.

LinuxCNC Controller Technical Information
Setting the Tool Table Offsets
The first thing you must do is home the machine before setting tool table offsets.
Begin by picking a spot to touch off to that all tools can reach. On the mill you might use the top of the fixed part of your vise. In any case what the objective is to set each tools Z offset to some common point so each tool when loaded with Tn M6 G43 the Z end of the tools will all be the same height.
Using the procedure found in the Mill Tool Touchoff section of this tutorial we will set the offsets for the tool table first.
Setting the Tool Table Offsets
- Go to the DRO tab and verify that there are no offsets in place for G92
- Load the tool
- Manual tool change put the tool in the spindle and do a Tn M6 G43 where n is the tool number in the MDI window.
- Tool changer just do a Tn M6 G43 in the MDI tab to load the tool.
- Verify that Machine > Touch off to fixture is selected.
- Jog the tool to the fixture point and using the dowel method position the Z end of the tool.
- Verify that the Z axis radio button is the selected axis in the Manual Control Tab
- Press the Tool Touch Off button.
- Leave the number at 0.0 and press OK
