For this build , i do not use Openbuilds profiles ( Sorry Mark ;-) )
I need for my workshop a big and heavy cutting table who can handle both router and plasma torch .
Overall size : 2500mm x 1500mm
Working area : 2250mm x 1300mm .
Until now , i never use rack and pinion drive , it will be the first try for me.
At the begining , i wanna build my own rack and pinion drive , but i finaly choose CNC router parts rack and pinion drives . Those are the only pieces that i bought already builded.
Description of the different technologies and products i used for this build :
Nema 34 hybrid ( with integrated coder ) , 8 Nm for Y axis and 4 Nm for Z and X axis.
X and Y axis are drived by rack and pinion system.
Z axis is drived by a 16mm ballscrew
Plasma Floating head
Auto scaring with two IFM inductive sensor ( Y1 and Y2 )
Homing on all axis ( X , Y1 , Y2 and Z)
Power suplly : 1 x 1200W 60 V , 1 x 400w 24V
The frame is based on a build i found on Internet and i modified it to enlarge the working area .
(I will write the source as soon i will found it again )
I made no concession for this build , so it's pretty heavy ( around 300kg ) and final price is also pretty expensive.
I made the choice to use only good stuff and of course , it have a price .
