Re: Oak vs MPU11/GPIO4D

Looks like the MPU11/GIPO4D only supports analog spindle output 0V-10V. What I need is -10V +10V for my spindle amp similar to how the servos are driven. Is there an addon board that will do this or can I just remap one of the servo outputs?

Oak vs MPU11/GPIO4D

I sold my previous retrofit iron but kept my old MPU11/GPIO4D. I've been entertaining putting it on a little VMC but now it seems there is new kid on the block. It looks like the MPU11 price point is still a tad higher than the Oak board. Is the Oak just a newer more consolidated version what what I...

Re: Thermwood 5 axis retrofit inquiry

Thank you CNCSNW. Makes perfect sense. I'm not sure why I didn't realize that the movement and articulation would actually be more of a function of my CAM. It's obvious now.

Thermwood 5 axis retrofit inquiry

I'm exploring a possible retrofit to a Thermwood model 67 5 axis router. I just wanted to confirm that there wouldn't be any issues with the way the head articulates and configuration in the centroid control. My only prior experience with the Centroid/MPU11 retrofit was 3 axis and that was pretty st...

Re: Encoder Basics

Yes I plan to use the scale for position correction. The rotary encoder on the servo will remain as it is. There are several scales I am looking at and the issue is different manufactures refer to differential quadrature signals differently. I'm trying to distill the differences of terms into actual...

Re: Encoder Basics

I am looking to use linear scales to help improve the accuracy of my axes. Can you please confirm if RS-422A / EIA-422 is the correct signal output I need to interface with my mpu11?

Re: Centroid software Vs Mach 3

As customer that has evaluated both I can give you some of my experiences--take from it what you will. I started with the Mach kit first due to the lower price point but mostly because I had already decided to go with Mach based on my research of EMC2 and Mach3. The Mach interface leaves a little to...

Re: SERVOS UNSTABLE WHILE RUNNING

It sounds like you still have some servo tuning to perform. The installation manual provides some pretty decent detail on the subject.
