Setting Up Tool Change Macros in UGS for the Wolfpawn

Multi-tool jobs require pausing the machine, swapping the bit, re-zeroing Z, and resuming. UGS macros automate the safe park and resume sequence.

The Problem Without Macros

Mid-job tool change without macros:

1. Machine stops at M6
2. You manually jog to a safe position
3. Swap bit
4. Try to remember where Z was
5. Probably wrong — ruins the job

Required UGS Macros

Macro 1: Safe Park for Tool Change

G91           ; relative mode
G1 Z10 F1000  ; raise Z 10mm
G90           ; back to absolute
G0 X0 Y0      ; go to front-left
M5            ; spindle off

Macro 2: Resume After Tool Change

G91
G1 Z-5 F500   ; lower toward work
G90
; Operator re-zeros Z here manually

Setting Up in UGS

1. Open UGS → Window → Macro Buttons
2. Click Add Macro
3. Paste the macro code
4. Name it clearly: "TOOL CHANGE PARK" and "TOOL CHANGE RESUME"

Z Re-Zero After Tool Change

After swapping the bit:

1. Jog Z down slowly to material surface (paper method)
2. Zero Z in UGS: Machine → Work Position → Zero Z
3. Jog back up 5 mm
4. Run RESUME macro
5. Restart the second toolpath

Organizing Multi-Tool Jobs in Aspire

• Save each toolpath as a separate file (Roughing.gcode, VCarve.gcode, etc.)
• Run them in sequence with manual tool change between
• Note: don't re-zero X/Y between tools — only Z
