Hi,
Just curious if someone can suggest a quick way to limit the speed of the steppers to prevent stalling and other issues. I've searched for a place to enter an extraneous delay, but am pretty new to the programming aspect. I know motor speed ramping is already used, but it doesn't seem to help when sending a motor home over a large distance on one of my more "loaded" axis.
Thanks,
Marc
Hi Marc, If you're using the
Hi Marc,
If you're using the TimeLapse Engine, it has a minimum and maximum step delay setting. The longer the minimum step delay, the slower the motor will go (i.e. this is the minimum amount of time that must pass between each step). The max step delay helps you control the acceleration ramp into a move, the greater the difference between max step delay and min step delay, the longer it will take to accelerate up to full speed.
If you're using Slim, you can use the 'stepper' command to do this, see 'help stepper' in Slim. If you're rolling your own code and sending raw serial commands, it's part of the engine control command.

Thanks Chris, That's awesome.
Thanks Chris,
That's awesome. I thought there was something like this and went looking for it, but didn't see "stepper" in the available help commands. Perfect!
