Re: question on hardware pairing and auto home/squaring

It's not really "auto squaring" and therefore doesn't use the slave input. As the manual states, you need to write a homing routine that uses outputs to control relays that physically disconnect the step wires of the two hardware paired motors. Your home routine would then connect one moto...

Re: question on hardware pairing and auto home/squaring

Auto squaring is not possible with hardware pairing.

Re: Intercon enhancement request

Which side of the arc or line should the finish pass be on? Should the finish pass keep the same arc angle, or should it keep the same chord length for arcs? For angled lines, should the finish pass be the same length, or should it maintain the same tangency points as the rough cut? Should finish pa...

Re: Wierd tool offset issue

edit: I'll add that I just don't understand why CNC12 doesn't know to use H1 if it knows T1 is present. Because you don't have to use H1 with T1. You can use H12, or H93, or any other height offset with ANY tool. This lets you do rough and finish passes with the same code by calling a different off...

Re: Can someone give me a hand with Intercon Lathe Chamfers?

position the tool tip where you want to start the chamfer before programming a chamfer This is the way all Intercon and G-code moves work. They all expect the current move to begin where the last move ended. This gives YOU the flexibility to program any moves you need to clear the work or any fixtu...

Re: my haas mini to hickory controller spindle motor question

For spindle orient, the VFD needs an encoder coupled 1:1 to the MOTOR shaft. For rigid tapping, Centroid needs an encoder coupled 1:1 to the SPINDLE. If the motor and spindle are connected with a toothed belt that cannot slip at a 1:1 ratio, then only a single encoder is needed and that is usually a...

Re: DIY acorn

You probably have not received any replies because very few people are familiar with systems that old. IMHO, the control is not salvageable. The drives and motors are not worth messing with either. New hybrid servo motors and an Acorn are the cheapest option for a semi-closed loop systems. AC servos...

Re: MDI spindle speed is not correct.

With the signal isolator disconnected from the drive, have you verified that the Acorn can send out 0-10V on the input side of the isolator using MDI and your max and min configured speeds? Does the output side of the isolator show the same voltage as the input at various speeds?
