Hello every body. Sorry for poor English. Is not my native language.
I finished my 5'x5' machine about year ago. Almost everything works fine.
The problem is Speed/accuracy.
I just did one test to run the same poly line shape at different speed(50IPM, 100IPM, 150IPM) and the result is day and night.
My machine is approx 5' x 5'
The motor is nemma 34 aprox 1200oz.
The power supply is from Kelling and is 72V and 20A
The servo is G320 Gecko drive.
All the ball screw is 1605 with and bearing support.
The speed set in mach3 is 6000 mm/min.
Acceleration is 200 mm/s/s
The bit used in application is 1/8".
When i mill at 50 in per min seems to be ok but when I run at 150 in per min the result is bad. Just look in the pictures DSCF5271 and you will understand.
Anny advice please.
Thanks.
Alexandru
