Thanks Shawn. I typically do not like to rely on enable signals, etc for estops. Dropping the raw DC power thru a contactor is a more reliable in that you are not relying on a microprocessor in the event of an "emergency".

Is there any reason I cannot run the individual ENABLE signals to the drives separately rather than combining them thru a NC ESTOP switch. I already have an ESTOP circuit that disconnects the raw DC power from the drives.

Thanks for the quick response

I'm converting my mill from open loop steppers to Clearpath SDSK drives on the X&Y axis. I assume I have Acorn ver 4 as it has LEDs on the I/O. I'm currently using H6 to connect to the open loop steppers.

Should I be using drawing S14972 as a reference to convert to Clearpath? It shows using 5vdc ...

Thanks for the help, I didn't mean to create work for you. I don't really have an icn file yet. I'm just now getting my shop made cnc mill running and was preparing to make my first part, which is a part for a power draw bar I'm adding. As I was programming it in Intercon, I was struggling with the ...

Hello, I was reading thru Tutorial #2 in the Mill Operators Manual (Draft July 27, 2023) and have a question about using Depth Repeat with Cutter Comp. I think there may be some typo's. At the bottom of page 192 it says "The outer contour begins with the Plunge operation in N0011 and ends with the ...

Well its been over a week since I’ve heard from CNC4PC. They have not returned phone calls or emails, what a shame. I don’t typically do reviews on companies but I would not recommend them to anyone based on my experience.

I got tired of wating so I developed my own interface using an ESP32 micro ...

Thanks, I'm familiar with both documents suntravel posted above. I wanted to use the PWM for better resolution and reduce the chance of electrical noise on the analog signal. And yes I did isolate output 2 on the relay board. I'm a retired EE with many years of experience working on commercial CNC's ...

Thanks. I’ve tried working with CNC4pc for almost 3 weeks now but they’ve been unable to provide a solution. I’ve sent them detailed information about the wiring, jumpers and screen shots of the scope. I really don’t know if I simply have a bad board or is it a bad design. When I asked for a refund ...

I purchased a CNC4PC C89 board to interface the Acorn to a Spindle Drive that requires a +/- 10 volt analog signal. The C89 is supposed to accept the spindle PWM signal from Acorn and convert it to a 0 to 10 volt analog voltage and change polarity by providing it with the VFD Direction signal. But ...
