    If wrote a c++ libtary that does cutter radius compensation, which might be usable for your purposes. Mine runs inside a cnc control but I wrote it to work mostly independently.

    Re: Concrete VMC

    I also am very confused, because I have been made to believe that a milling machine should have a spindle capable of 10-12krpm. Where as a router typically has a max spindle speed of about 20krpm. My...
  4. Machine Vibration/Deflection Analysis before/after epoxy.

    Hey everyone!
    I have been building a vertical mill. Its primarily constructed of 0.375" (9.5mm) steel plate. The steel sections are hollow, consisting of a plate with short sides, and bracing across...

    Re: 4th axis and GRBL with MEGA?

    I may be a little late to this convo. If you are looking for a 6 axis version of grbl, Heres is a version I have on github.

    Re: Adding encoder to stepper motor

    I don't know the specifics on how that servo needs to be driven but I would imagine it is similar to other servos requiring a driver, tach, direction, and so forth. I have some parker allen servo...
  7. Re: Closed loop microstepping - similar torque penalties to open loop? Questions...

    I used 5mm pitch ball screws in my setup. I have some closed loop steppers, and they are no different in performance than their open loop counterparts. The closed loop stepper and driver I used can...
  8. Re: Are my stepper motor expectations too high?

    I run an identical driver and similar motor configuration, however I used NEMA 24 motors. I have used the DM542T drivers, but I went with a power supply per axis. They are 60 volt 6 amp supplies...

    Re: Adding encoder to stepper motor

    Right.


    Also correct.


    You can certainly get accuracy out of it. And the version of the code I have below makes it reactive like a servo. If you move the stepper it will move back IF your...

    Re: Adding encoder to stepper motor

    Yes I completely agree it would be much easier. However a scenario like this is what I wanted to be able to handle:

    You are cutting a circle/angle/ (any movement that requires the coordination of...

    Re: Adding encoder to stepper motor

    I know this thread is a bit dated, but I'll explain how I have encoded a stepper motor. I have a DM542T driver running a dual shaft NEMA 24 stepper at about 1200 RPMs. The way I set mine up was to...
