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.

Re: Relay 17 backwards?
Fault output relay 17 has continuity between COM and NC terminal with no power applied to MPU11 and GPIO4D boards. That sounds like expected behavior for a normally closed circuit. The E-Stop circuit operation does not affect relay 17 outputs. Do you mean a software estop in Mach is not affecting r...

Re: CNC11 Homing with single limit switch
coming across this post I see instructions to only wire the limit switch for the direction they will be homing in. http://www.ajaxcnc.com/ajaxbb/viewtopic.php?f=20&t=92&p=388&hilit=homing+limit#p385 I supposed I can utilize this as a work around and fashion some brackets for additional l...
