need help tunning step motors
hi i am a complete newbie at setting up a cnc. i have ran one for work for the past 6 years but never set up a new one.
what i have is a home made plasma table 5x5.
i run the mach 3 software
the problem i have is my x and y axis step motors run very jerky and make grinding noises and not even close distance its supposed to.
all three motors are nema 23
x and y are belt driven to i believe a 3 to 1 reduction i have not counted the teeth yet.
any help would be appreciated
Re: need help tunning step motors
Could you share some more details about your setup, like what drives you're using, what settings you've chosen, what the specific motors are you're trying to drive, what is transmitting the power to them (eg: screws, rack and pinion) what you're using for slides, and why you decided to use a 3 to 1 reduction? Does this always happen, or just when your plasma cutter is on?

For the beginning, enter motor tuning and lower velocity and acceleration and start from there.
On Mach forum you can find a ton of documentation.
