Got it running now for about a week with the viper drives. Runs fast and smooth now. No more faulting and much quieter.
I will post pictures.

I'm running Mach2 with Viper 100's on my mill. They work well together.
The nice thing is the Viper is easy to connect to. The Fault line just gangs off the 3 drives and goes to the E-Stop input...

I'm setting up Viper servo's on my mill. They are working real well. Are they size 34 or 42 motors on your mill ?

Use one large steel tube instead of that small tube welded truss. Don't you realise steel bends where you weld it !

That thing would be bent and twisted like a pretzel.

I posted in the other thread, but

I'm going to be using those motors with Larken Viper drives. Ordered them last week. The guy at Larken said they work great with his drive. He said the powersupply should be about 30 volts for that...

I'm building a CNC router and i want it servo, since now its just as cheap to go servo as stepper.
I got some nice Minertia R series servo motors off Ebay I'm looking at Rutex or the Larken...

The Gecko is not a true digital PID controller. The analog filter is just a simple low pass filter. Also there is no Intregral component you can adjust. On a low count encoder they should work, but...

I've been checking out some other servo drives and i've decided to order 3 Viper drives. They have a lot of features and have a money back garantee if im not happy.

Are they DC servo motors. Check out drives from Rutex or Viper drive. I've tried Gecko, with not a lot of luck.

I'm not familiar with the deskcnc, but why does it ruin a part when you Estop ? Most controllers don't mess up when you hit the Estop or a limit switch !

You shouldn't run a stepper more than about 10 turns/ second , after that there torque is about 1/10th of the holding torque.

The higher the supply voltage though the faster you can run it,...

That doesn't really make any sense. Have you tried hi-res encoders on other servos before ? Why would Fanuc, Teknic, and others recommend hi-count encoders? For increased smoothness of course !

...

For the same gearing and same motor/drive, won't a finer encoder produce a smaller error ?

Drives still not working reliably. Why is there not a dedicated error trip output. Gecko should use a...

Yes, but thats encoder resolution of 0.0001" . The servo error can easily be +- 20 encoder counts at best while cutting so the machine accuracy is only 0.002" .
I want accuracy on the mill.
Fanuc...

The encoders are US digital. Current draw is far below 50ma.

Why do you need a lower encoder count ? Less than 1000 lines puts it into stepper territory.

US digital sells encoders up to...

I've retrofitted my bridgeport mill with 3 MCG ID33004 servo's with 1000 count encoders. Im using Gecko 320s and Mach2 .

The XY drives fault randomly, mostly under heavy cutting or under...
