« on: September 11, 2007, 05:56:33 PM »

my spindle has a 4mm pitch so i set my motors to 400 steps to turn the motor saft one full turn so if i alter my drivers to 1600 steps for my spindle to turn once will that make it smoother

General Mach Discussion / stepper motors drivers

« on: July 24, 2007, 07:28:15 AM »

could someone give me a bit of advice on stepper motors and drivers, i
have built a cnc router and i bought a complete kit of steppers and
drivers plus power supply off e bay, but the motors are not strong
enough, if i attempt to run them any quicker than a snails pace they
dont like it,and growl, the driver board is a 1 axis simplestep
(aliencnc.com) and it says maximum 30...@2.5 amps/phase motor output,
for use with stepper motors rated at 2.0 amps/ phase or higher. the
power supply is 24...@4.5 amp switching power. can anyone tell me the
strongest stepper motor that will run with these boards, the motors i
am using now are FL57STH76-2808B ones, or do i need to buy a more
powerful motor and driver/power supply.

many thanks

General Mach Discussion / limit switches

« on: July 16, 2007, 04:17:43 PM »

ive, sorted the stepper motors,got it moving a treat, but could someone tell me how to connect the limit switches, ive tried a few things but nada, nothing stops my motors from moving, do i have to connect a wire from the switch to the motor driver then to the db25 connector or do i just connect the switch straight to the db25 connector,

many thanks
