I have been updating an Industrial CNC Router and chasing a problem with my Z axis for quite some time. Unfortunately, I only have 1 day every week or so to work on this issue.

I have added the Acorn control board as part of the update. I have replaced the stepper drivers with ones that match the ...

I have been converting an INDUSTRIAL CNC Router. I have changed out the original drivers and am wanting to use the drivers that are specifically specified for the stepper motors that came with the router. I have the new drivers but the wiring diagram does not make sense to me. It is creating a ...

Is there a way to check to see if the Acorn board is producing step and direction outputs. I am having difficulty controlling a stepper motor axis and have tried 2 different drivers. One driver worked for a while the other driver sends power to the motor. The motor is locked in place but when I try ...

Tim,

Can you update me on where you are on your Industrial CNC router rebuild? Specifically, have you gotten the closed loop stepper motors and drivers you mentioned to work? I have upgraded the piece of crap BOB that came with the Industrial CNC router to Acorn. I have had limited success getting ...

I went back and checked the wiring several times. It is correctly wired. I have also gone back and checked/changed the parameters of the VFD; however, I am still stuck. I have tried to clear up some terms. The control on the VFD is referred to as a keypad. Many selections refer to "keyboard," which ...

I am using a DZB Fuling VFD.

I have been working on the VFD setup today. I am having limited success. I do have the spindle turning on and off through CNC 12. I am using an Acorn 4-axis board.

My current problem is that I cannot control the spindle speed through CNC12. I am using VI (voltage input ...

Thanks Centroid467! So far, so good. I hooked up S1(Spin Fwd) and GND (Common/Return) wires to the OUT4 relay , and the AVI and ACM wires to H8 on the Acorn. I added a wire from S4 on the VFD to the Out6 relay on Acorn, a wire from the VFD C terminal to IN5 on Acorn and finally, a wire from VFD B ...

I am also trying to connect a Fuling VFD to my router with a standard Acorn board. You have more wires than I do. Coming from the control board on my Industrial CNC Router, I only have two wires. S1 (Forward) Going through a relay. And DCM(Ground) This means I can only turn on and off the spindle. I ...

Is it possible for the Acorn to use step and direction to drive an AC Servo so it can be used as a spindle motor?

AC Servo motor -AASD 1.8 KW

Thanks for your comments and ideas.

I finally got my spindle working using ACORN's analog output or at least I can turn it on and off and increase and decrease the speed. However, when the motor is enabled on the AASD driver the servo turns at 45 rpm. This is without the ACORN on. When the ACORN is on, the RPM in CNC 12 and the RPM of ...
