Hey guys,
Im setting up my motors in mach 4, Ive got a routakit HD with a stdr-4c controller with nema 24 motors. Im at 2000 units per minute (x axis) and it seems like its still running great. I don't know what a reasonable number would be. How much faster can/ should I go????

I think Craig has given someone a good "formula" for stepper velocity before, somewhere on this forum.
But here at the shop, I keep bumping the velocity up a little at a time until the motor stalls; once I find where it is as fast as possible without stalling, I back off about 20%. Works pretty good for us.

Thanks! That's the same method listed in the Mach manual but Ive never experienced a stall. Is it hard to miss?

You'll know when it stalls.

Gerry is correct. lol You will know when it stalls. The table will stop moving and it'll make a funny noise.

Thanks guys! On my X axis im so fast now its uncomfortable. Is there any reason I cant run at a lower velocity? I assume you want any velocity that is satisfactory as long as its lower than that 20% of max velocity?

That's entirely up to you. I have a Carbide Knife Grinder in the shop that can move at 200+ IPM but I've got it set to 40-50 IPM because I don't want the operators to crash the machine because they aren't paying attention.
