@printingmark Mark, I would suggest that you look at the following
M566 X1200.00 Y1200.00 Z24.00 E300.00 ; set maximum instantaneous speed changes (mm/min)
M203 X30000.00 Y30000.00 Z300.00 E1500.00 ; set maximum speeds (mm/min)
M201 X500.00 Y500.00 Z100.00 E5000.00 ; set accelerations (mm/s^2)
I beg anyone to please insure that I am giving the correct information and help for him. I am very new the REPRAP Firmware. Mark, please change that code listed above thats in your config.g file to the following
M566 X600.00 Y600.00 Z12.00 E150.00 ; set maximum instantaneous speed changes (mm/min)
M203 X3000.00 Y3000.00 Z30.00 E150.00 ; set maximum speeds (mm/min)
M201 X500.00 Y500.00 Z100.00 E500.00 ; set accelerations (mm/s^2)
The way you described your problem makes me feel like your stepper motors are skipping big time. I had this very same issue and I had to basically lower all those values down to almost nothing. After changing those valves listed above, my printer started to work like a champ. Produced some nice prints.
I own a Tevo Black Widow. I know you said you own an Ender 3. Those numbers I listed above for you to change will not hurt anything at all. But you can play with them so they fit your printer. I am only suggesting those numbers as a guideline to start at.
Keep us posted on your success.
