ShopSabre CNC Router Tips and Hacks
We have a 2017 ShopSabre PRO 408. We’ve found a few ways to improve it over time. Here’s a few of those:

Spindle Warmup
Warmup Location
We adjusted where the spindle warms up so we can do some setup on the front of the machine and have the spindle be spinning safely away from the tool rack as well. The location on our 408 we like is X25Y60.
After warmup, Move to Back left
We found that the machine moving quickly to the front of the table (near the origin) felt dangerous as we are commonly setting up fixturing or a job. Instead, we have it go to the back left or X-4Y98 so it’s totally out of the way and not moving at where the operator is most likely to stand.
To do this you need to edit the WARMUP.MAC file in the WinCNC folder. Make sure to do this while you are not running a job.
You should compare our code below to your file and make sure to only replace the parts you understand.
Most likely you’ll need to restart WinCNC and re-home the machine before using this new code.

Dwell - Make a note
Do you have important places in your operations where you need to watch for a tight tolerance or add more fixturing like screws?
You need to use a Dwell! The code, G4 will cause a ShopSabre to stop what its doing. WinCNC will show a dialogue to ask you to Push Enter to continue.
We used this for many things. Mostly for making sure the operator does something in the right order or as a reminder like, “DID YOU CHANGE THE ORIGIN FOR THIS OPERATION?”
You can hand-edit the code as needed in a text-editor but we use Fusion 360 with a pass-thru NC Program operation.

Modify Bed for Fixturing
We drilled and tapped our ShopSabre CNC Router frame to add more work holding options. Let's walk through how we did that.
