Garage CNC - A gantry style machine design

[JAZZCNC]

Hi all,

Had price for extra RM1605 leadscrew and ballnut, BK/BF12 blocks and end machining for 145USD - think it's worth the extra after listening to your advice.

Hoping to machine various materials, but engraving in slate would be my primary initial use as several people have asked if I can.

Honestly it's my mid-life crisis toy - better than a sport's car in my opinion
Thanks for the help.

Can i just say the way your going about it and buying stuff without research or asking then it's going to cost as much has any sport car.!!

So far your component choices are severly going to restrict your goals.!! . . Motors are most likely too large and I'd wager your PSU will be Too low a voltage, on top of this the 5mm ballscrew pitch is too slow to be ok for cutting awide range of materials. The combination of the motors and the screws will make it very hard to cut softer materials that need higher feedrates, softWood's, plastics etc will all need feed rates higher than you'll probably achive with this combo.
Slate and harder materials won't be a problem has they will require low feedrates but then you'll need to mind the spindle and machine strength and cutting conditions. Like someone as said 40mm box just won't cut the mustard so you'll want to beef the frame. Like Eddy say's Stone, slate etc needs water or cooling so you'll want to think about that otherwise tool wear will be high and costly. The spinlde is also a bit too fast for stone cutting correctly but will just about be ok for engraving slate with correct tooling and conditions.

Now please don't take this wrong way and think I'm pissing on your parade or just giving you a hard time for the sake of it, i'm really not. What I'm saying is you need to take a step back do a little research and ask some questions, Start a build thread and post up your thinking or ideas.

If you don't slow down then you risk a very big chance of being dissapointed with the outcome and high risk of wasting money. I wouldn't buy another thing untill you have come up with the machine design because so far you have made some typical newbie mistakes which are going to limit what you'll be able to achive with machine.

Best advise is start a build thread and post the design or ideas and thoughts for the design and we will guide you in the right direction.

PS: Sorry to be so blunt but it needed to be said for your wallets sake.1
