Re: Looking for ways to smooth out the movement of my stepper motors.

I did not think to try increasing the voltage. Except for on my drivers which is set to .800v and .900v on X and Y. Right now I am at 12 volts and the max I can go to with my PSU is 19.5. My Ramps board should be able to handle it so I think I will definitely give that a shot. I'm slowly getting it dialed in, I have been tuning speeds settings for about 3 days alone. I have been doing some reading and I have been looking into the problem you mentioned. I need to get my rpm's down so I can get some torque and speed back. I am trying to tune my setup for at least a comfortable 40mm/sec. Right now, after a few days of tuning, I can squeeze out maybe 20mm/sec. I didn't realize the limitations of leadscrews when I built the printer, especially the cheap ones I choose. I was able to find a little cheat to help, I turned my jerk setting waaay down between 1-5 to give me a nice cushion when changing direction and I am slowly trying to dial my acceleration in as high as possible and it is working but I am having a little trouble with resonance. I tried to give 1/16 microstepping a shot (currently 1/32) but for some reason during testing my motors spun extremely fast and would stall whether connected or dissconnected to leadscrew.
The second part you mentioned is actually one of my biggest limiting factors right now and is the reason I attempted to try 1/16. I normally set my speed in Cura to 40mm/sec and I will just print at a fraction of that and dial it up depending on performance. But, it seems like anything past 60% and it starts getting real choppy and freezes. Looking at something relatively cheap in the 32 bit range.

Right now I am at 4030.23 steps/mm on X and Y and 2048(1/8) on Z.
Which seems to be way to much for an Arduino Mega.
Thanks for the links I am going to check them out.
