Re: CNC12 v5.30 Mill, Lathe, Router and Plasma has been released. 3-7-25

I'm having trouble upgrading from Router 5.24 to 5.30. The Wizard will not accept the Overall Turns Ratio for my rotary axis "A" that I used previously. I downloaded the most recent installer files (yesterday) before I started, so they should be the correct set.
Can someone take a look and help me ...

Re: Stepperonline wiring for CL57T drive to ACORN CNC controller

StepperOnLine CL57 V4.1 Driver.jpg
I recently got in a couple of new CL57T V4.1 drives and they now have a new entry in the signal block. After ALM+ there is now BRK and COM. There is no longer an ALM-.
Is this covered in a different thread?
Otherwise, FYI

Re: Manual machining still possible?


I'll use AC servos as described lately by Uwe and I hope they handle braking properly.


Check the manual for the drives you will be using. It should say what which models come with a braking resistor installed or if an external resistor should be provided. Most AC servos systems I have seen ...

Re: Manual machining still possible?


I guess this is independent on Acorn.
Turning any PM motor (regardless if PM servo or stepper) will generate a back EMF voltage (proportional to speed) that goes back into the driver. Whether the driver could be damaged or not depends on the driver. I'd guess mostly not, but you are generating ...

Re: Manual machining still possible?

I have a slightly different question on manual machining.
If you have the Acorn powered off (and everything else), you can turn the stepper motors to move the axes. So in that sense you are manually machining. However, is there a danger of generating reverse voltage from the steppers back into the ...

Re: Acorn CNC12 v4.80 has been released. (8-12-22)

Keith,
I'm sorry, I thought I answered your question.
First thing is that everything is working great now!
The only thing I could see that was messed up was the connection settings. I use the DB25 pin breakout and I found it was set to Screw Terminals. Once I got that all sync'd up, life was good ...

Re: Acorn CNC12 v4.80 has been released. (8-12-22)

Keith,
That worked on both systems.
I should have been a little more specific earlier, no both systems are not set up the same. The second one is a work in progress.
But both are running CNC12-4.80 correctly now.
THANKS for your help!!

Re: Acorn CNC12 v4.80 has been released. (8-12-22)

I have been able to replicate this problem on a different PC and Acorn board.
Under CNC12-4.62 everything works (I only have the Z-drive connected, but it spins when I click on Z+)
I made copies of all my Wizard screens and saved them. I renamed the old CNCT directory to CNCT-4.64 and downloaded the ...

Re: Acorn CNC12 v4.80 has been released. (8-12-22)

Sword,
Thanks, but I checked the current Centroid-recommended wiring schematics for my drive and it hasn't changed.
Input 5 is DriveOK
Input8 is EStop.
I'm not sure where you got your recommendation from.
