Hello,

This is my first time posting...

I am in the process of building a large 12' x 10' hot wire foam cutting machine. I would like to hear from those individuals that might know the best size stepper motor to use. My main concern is for the stepper motor that will move a 80lb. gantry in the X direction. I am am not to worried about the Y axis as it is only moving a hot wire up and down. I am looking for a general idea and all the help is appreciated, thanks in advance:)

hello,
i would too ask something,
i would like to make foam and woodwoorking machine. since i have no expirience,
can somebody tell me can i move this tool

Thank you for replying to my post...

Do you believe that Nema23Package has enough torque to stop and move a 80lb. gantry...
This is rack and pinion transmission on vgroove linear guides.

If you geared that little motor down to have enough torque, it would just crawl along. Above a certain size (and you're there) servo motors make more sense than steppers.

Try this take a scale (weight measuring device) and move the disconnected gantry along it's axis and see what weight it requires to move the gantry and use this to determine the motor size in torque. remember motors quote stall torque when you are determining the size you need.

Simple. using a gear or belt transmission you can move what ever you want with the smallest motor. Think about a can opener. if you look inside you will see a tiny motor that drives a STEEL cutter. as you reduce rpm you increase torque.

see our pro foam cutters. even call me for a smaller machine !!! (http://www.astatue.com)
