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.
