Centroid Community CNC Support Forum

Good evening all,

On my list of things to do is build a control for a single axis drilling machine. (Basically just the Z axis on a lathe).

I believe the intended path forward is to use a Centroid acorn. I've done an oak retrofit several years ago, but not an acorn and i've not really made the ...

I'm not sure how to get Keith to look at this again and weigh in on the issue you pointed out Marc.

Engineering responded to my question regarding internal positioning profiles which are available on some drives. In this case it appears no there isn't an option for that. They do allow up to 4 "home" positions so you can clock the spindle in up to 4 discrete positions, but there doesn't appear ...

That would be part of the battle. The other part would be figuring out how to get the Centroid Mill software to deal with an axis that comes and goes: that sometimes is available for positioning, and other times will just spin for no reason apparent to the motion controller. The Lathe software ...

I've been chatting back and forth with the engineer which has been pretty handy. It appears there is an input L4 on the drive that will switch the drive high speed mode to position mode. So I believe I can basically use the spindle as both a high speed machine spindle as well as a positional ...

Turns out the engineering group at SZGH is readily accessible through whatsapp.

Looks like these spindle drives are controllable through step/dir input. The engineer I was able to reach explained which wires accept the +/- pulse and +/- dir inputs as well as the parameters to change to run in ...

This is the manual for the motor/drive combo I have.

Same spindle setup different website. Specs are the same so presumably different face for same company.

So it sounds like you need a spindle motor that is capable of servo-like positioning, so that it can rotate exactly the right amount to index the carousel from one tool to another.

What kind of drive and motor do you currently have running the spindle? You said that the original spindle servo had ...

Good evening all,

I wondered if any of you had experience with a fanuc robodrill. I bought one last year that had been partially retrofitted to Centroid. It has a centroid oak in it and DMM servos.

The spindle a direct drive servo motor and was replaced as part of the build. I really haven't ...
