« on: June 11, 2022, 10:36:31 AM »

Good Day All,

Sorry If this is in thr wrong section.

I have a home built CNC router running mach 3. Was built in 2011.

Long story short.... Left machine running a finishing pass on some vacuum forming molds came back once finished and the spindle was sitting very randomly spinning in a none natrul way. https://youtube.com/shorts/OUIfTT_EAKI

Parts I have changed thus far....

A new pmdx 126 and 107 board have been fitted.

If any one can shed any light onto this i will be greatful as you all know, Its an expesive table if its not cutting.

Thank you in advance

FAQs / Noobie question regarding cutters.

« on: September 19, 2011, 10:28:37 AM »

Hi guys, Tom here from sambonnie design.

We have purchased a rscnc twin head router.

We are a Kitchen company and we are using the Cnc to cut all doors, panels and cupboards.

We use mdf for our doors and mfc ( chip board ) got the cupboards.

With your guys knowledge and experience with Cnc machines what cutters to use for both as I don't have the money to throw away on the trail and error route.

Kindest regards in advance

Tom @ sambonnie
