Hello everyone I started building a plasma table which 1000x2000 mm in size.
I already have some drive components and I want to use them not to pay for new ones and they are:
60 Teeth T5 pulley
20 Teeth T5 pulley
Mod1 Rack
Mod1 22.70 mm. pinion
6A 8.5 Nm Nema 34 stepper motor
Are these ok for my table ?
And in an other form I read that "Best motion on a stepper plasma setup is 1 inch of linear movement for 1 revolution of the motor."
Is this argument correct and if it is , will my setup accomplish this statement.
And if eligible can you provide a formula how to calculate linear movement per revolution.
Thanks in advance

To start you need to know what RPM your stepper will do then the max speed calculation is simple. What parts are going where? In my case I have a small pulley on the stepper like 20 tooth or so with a belt to a larger 60 tooth which then has a smaller pulley that drives a belt.
What is important for a plasma is you have high acceleration and can go the fasted you need to go to cut the material you plan on cutting. So for a stepper system you want high voltage for the drive so it can do high acceleration.
There are some pages on the wiki but it seems to be down at the moment.

as you already have the parts there doesn't seem much to be decided, other than whether the big T5 pulley goes on the pinion or the motor.
It would normally go on the motor.
How fast can you spin the stepper under load with your drivers?

If you decide to use zero back slash gearbox, which reduction would you use with 8.5 Nm Nema 34 stepper ?
1/5 or 1/3
1/5 or 1/3

That would depend on the speed and torque of the motors, the gantry mass and the speed / accelleration that I was targetting.
1:5 will cut tighter corners, 1:3 will go faster.
