My first cnc machine.

I see were your coming from with the wear of the angle, but ive ordered some.... getting to excited and jumping into things.

Its kinder going to be once its worn unbolt it replace with something better might even make a nice trailer ramp out of it.

Has usual with all things CNC it's not has simple just worn out rail. Stepper motors lose torque has the speed rises so any friction is to be avoided and has the rail wears the friction or sticktion will increase and you'll get stalling motors. Also Ali is soft and graby steel is much better.

I intend to use the mod 1 track with an suitable pinion, might be sounding dumb but what do I need to buy to make it run 3:1?

Timing belts and pulleys. I use HTD Series on routers/mills.

Okay great. I intend to purchase my rack and pinion materials some time next week.
Having these materials will help me picture what I need to make regarding brackets for sticking it all together.

Started building my table today, A pic of were Im up to.


Its all braced up and tacked ready for welding.

Decided to do the table 2200x1200 giving me plenty of room inside for 2m x 1m sheets and gantry parking.

I used mod 1 rack on my machine, I was a bit unsure to start with thinking I might have been better with a size up, but it seems to be working a treat, I would use it again.
