If you have trouble...

Try lowering your Gain settings in the PID . Kp and Kd a bit

Do you know if it made that noise before you tuned it.. of did you tune it ?

Yes, Im still in Business . I had website problems when google wanted everything with a 'Secure Certificate" but it should be working now.

The Viperservo.com should be directed to my main...

Get some heat transfer pads and some thermal grease . You can also bend the mosfet away from the pcb a but and put a small cardbourd strip on top so it has more pressure

I'm not as up to date on the latest cutting edge technology for multi ghz processors as you guy's . But what im seeing is most of the 10-20 year old Atmel , Microchip and motorola etc.. 8 and 16...

Ya.. Steel and almost ever other product they have copied and sell back cheap. Who invented the PC and all the circuit boards that go with it ? .. not china. Who invented Telecom ( nortel...

But really it wouldn't it be better if factories were spread around the world in numerous ( non communist ) countries instead of putting all your eggs in one ( very powerful ) countries basket ? ...

Sorry, but i can't agree with you there. Its weak policy that is causing the mess the world is on now since Trump left. Tarrifs should be heavier if they are copying or dumping products. We were...

Its the News that only mentions the Auto sector electronics being affected, but its any popular electronics thats it short supply now. But the shortage is affecting everything else, so its...

Check this out .. zero stock on the main parts i use on the Viper servo drives . This is the current state of electronics, its pretty bad .

I have recently had some customers in europe having problems setting up drives. I then asked them to email me their vipertune settings in a screen shot... and all the settings were all ZERO !

You can use a switching PS, but it has to have a Clean DC output . If adding a capacitor fixed it, then the PS was not out putting clean DC, Sounds like a poor quality PS. Maybe just get a 12V 2...

Yes its in the top of the spindle

I built those machine with the TC in 2000- 2001 . It ran on Lcam that had toolchanger controls integrated.
The Mach3 must have been put on later, you are on your own with that .
One mistake i...

... better late than never

Yes on the Viper 200 series, the control side is opto isolated from the power side . So input signals and encoder are running off the low voltage safe side. The main...

It could be hitting the top of the PS region where its hard for the pid for control the motor. I had sent some out with a PWM clip setting that was off .It should be set to 1700 on V200H

...

Its because you probably have noise between the drive and bob so try adding an RC filter in the connection. Try adding a 200 ohm resistor and a 100uf Cap. I'm helped you alot but when you start...

I've added some features and improved the tuning ability of all Viper200H and Step2Linear drives .
Email me for how to return to have the firmware updated. Its free, just pay the shipping.
Note :...

Hi
I've updated the S2L to a 12 bit Dac for smoother control and no dither. The original used an 8 bit Dac that gave a resolution of +- 128 levels of 0-10V output. I'm now using a 12 bit serial...

What controller are you using ?

Anyone have experience with the Hurricane Black box Vacuum System ?
How reliable is it and how well does it work on a 4' x 8' router ?

Im debating either that or a 10-15 ho regen blower
...

Maybe contact Larken ?

Really...Why don't you just Contact Larken ?

I just posted a tuning video.
What are the motor ratings. contin stall current and what PS voltage are you running ?
Also what frame size is the motor. ?

The jumpers on the V200H are just for...

No, it doesn't use the index pulse to close the loop, but you may be able to opto-couple it back to the motion controller to use in the homing.
But the encoder wires and ground should only go to...

Here is a Video on setting up the Viper 200 and Tuning it.
