Ok I purchased this unit from K2.
o KG-2525-G
o 305 oz.in. servos
o 3 axis Gecko controller
o THK Rails and screws
o Colombo 3hp 18k rpm spindle with Delta drive
o Mach 3
o .750" t-slots table
$11,638.99
I have powered it up and jogged it around. It has a horrible growling sound when moved. The Y axis (bottom) is the worst. But both X and Y are very noisy. Also the PID isn't right because both the X and Y axis make a constant wining sound. Again the Y axis is the worst.
I have contacted them and apparently it's my responsibility to verify that this isn't effecting the accuracy. They are telling me a small percentage of the machines have this problem, if it is a problem...
I'm not new to CNC, but it's been a long time. My first machine was really quiet and smooth moving. It was called the CNC Crafter when they were in business.
Am I expecting too much?
Does the hunting sound from the servos indicate a problem?
I also have a bunch of Mach3 questions, but will start a thread in a more appropriate place for that. Looking for feedback good or bad.
