Print quality on different computers

Just had a " Well, that's interesting, moment"

I set up my old tower computer to run my prusa and coppied the settings from the laptop.

All settings are identical and I haven't changed anything on the sprinter settings.

I used the same printer to pc cable but the print from the old tower was skipping steps on the Y axis so I changed the cable back to the laptop and the prints are coming out fine.

This maybe something to do with data transfer rate and may help others out there having problems with skipping steps.

Any ideas?

I have included a pic showing the 2 prints. The one on the left is the one from the tower and the right one is from the laptop.

Although I have not noticed missing steps, I have noticed missing retracts. Have decided that for me I always print directly from the SD card for best quality.

Hey Jim,

Yeah, that's what I have decided to do also But I gotta wonder how many others have had problems with print quality just because of their computer feed.

Lucky I decided to start this journey on the fast computer.

It's really dependent on what electronics you are using. I am using the Printrboard and all commands are cached before they are executed. For some electronics, yea, you will need a faster computer especially if you are using a serial port.
