Centroid Community CNC Support Forum

CNC12 has provision for up to four spindle gear ratios. This allows for high/low gearing like on a Bridgeport knee mill, or a lathe with a gear-head spindle. Centroid will apply the appropriate gear ratio and display/command/use the correct spindle speed. The issue is how to tell CNC12 what gear you...

https://centroidcncforum.com/viewtopic.php?f=63&t=1650 tells how to calibrate your VFD.

Parameters 65-67 control the spindle gear ratio settings. I believe there is also a setting in the Wizard for this.

G28 is the correct method, but if you want to program ypur own moves, first delete the G28, and then use G90 X0 Y0.

G91 is INCREMENTAL move. You are asking the machine to move nothing in X and Y.

Since you say you've made changes to the tool offsets and WCS, please post a new report as well so we also have the new settings.

The g-code you are running might not have a G28 command in it. Perhaps if you posted the g-code file along with the line number where you think the error is occuring, we might be able to help instead of just guessing. Attach a machine report as well so we can see your return positions. It's not poss...

I'd go with a Centroid 10in/lb servo on X and a 16in/lb servo on Z. Centroid DC Servo Motors with encoder and cable installed (middle of page) Remember, this is a light-duty high-precision toolroom lathe. You not going to be hogging material with this machine so huge servos are not needed. Space on ...

If this is a non-closed loop Acorn system, you'd need a UPS sized to provide power to both the computer AND drives in order to prevent position loss during a brownout or power loss.

Just keeping the computer going so it can send pulses to drives that are off is not going to solve the problem.

As I mentioned in a previous post the Intercon file is in the icnlathe directory. The. .cnc file is the compiled g-code. We would like the Intercon source file to help you debug.

Other than the comment about your finish feedrate, ignore that last post of mine. Your tool change position is probably correct but we won't know for sure until you post the Intercon program and a report. With those two things and what tool number is your reference tool, I can load your report on a ...

If CamBam doesn't have a Centroid specific post processor, it will most likely have a Fanuc one. CNC12 should have no problems loading and running Fanuc compatible g-code.
