Tramming Front to back  
As time goes on, we here at CNC3D like to innovate and improve on our machine designs to  
make things like tramming your spindle an easier and user‐friendly process. One of these  
improvements is the addition of a “shoulder bolt” on the big Y‐axis plates. There will be  
some machines that have these bolts and some that do not so ensure you are following the  
correct tramming procedure for your machine.  
If your gantry has a shoulder bolt  
Shoulder bolts have a washer on the bolt as seen below in BLUE. If you have no washer then you need to follow  
the below guide for “NO shoulder bolt”.  
If you need to adjust your tramming front to back then we need to look at adjusting the  
gantry angle.  
To do this, we first need to loosen off *slightly* the shoulder bolt highlighted below in BLUE.  
Once these are loose, loosen all of the bolts highlighted in YELLOW below.
