Yes, it can work with an encoder or an index pulse.? Check this out: https://www.cnc4pc.com/blog/post/mach4-lathe-using-the-ethernet-smooth-stepper-and-the-c82-breakout-board

Thank you Steve. That's the information I was looking for. In fact I'm surprised that they are stating 10V for the input supply voltage since even rail to rail op-amps don't quite get to the rail

Well, sort of...... The circuitry works better at 10 or 12 volts, but it will function at 5 volts. The issue is that the output range is limited to between approximately Gnd plus about 0.3 volts and

I realize this isn't completely a MACH question but many MACH users have G540's connected to their systems. The VFD pins are the ones I'm wondering about. The specs say optically isolated PWM.

Nothing that I noticed, but I didn’t really try to find any differences either. Threading (once they finally made it work) was fine with either method. Sent: Thursday, March 16, 2023 6:03

Thanks. Did you find any difference in behavior? John Sent: March-16-23 3:01 PM To: [email protected] Subject: Re: [MachCNC] MACH4 and Lathe Spindle encoder I ran Mach4 for years using a

I ran Mach4 for years using a single-pulse setup. I only changed to an encoder a few years back Sent: Thursday, March 16, 2023 5:43 PM To: [email protected] Subject: Re: [MachCNC] MACH4 and Lathe

It's just I had a question on how hard to migrate from a MACH3 1 PPR to a MACH4 system and whether mechanical and electrical changes were required to use MACH4 due to a quadrature encoder requirement

It works either way, unless something has changed in the last few years Sent: Thursday, March 16, 2023 5:02 PM To: [email protected] Subject: [MachCNC] MACH4 and Lathe Spindle encoder Can

Can MACH4 Lathe still work with only a 1PPR spindle sensor or does it now require a full quadrature encoder and Index pulse?

I have found that if your computer has trouble letting you use an Arduino comm port rebooting the system fixes it for me. Sent: March 12, 2023 4:23 PM To: [email protected] Subject: Re: [MachCNC]

Yes I veryfied and it is recognized as a Com port (Arduino Tool Kit was already installed). Just tried to change the USB port but still the same, modified the Com3 to Com4 label and still the

For example. I took a fairly new WIN-10 system that had been upgraded from WIN-7. Even has MACH3 on it although I don't use it. I plugged in an ESP32 DevKit1 and came up with the screen that shows

Ok.? Bring up the device manager and see if the aeduino shows up as a serial port or under USB devices as unknown.If unknown you can try installing the Arduino IDE which will likely install the

This is just a USB arduino connection...

How are you connecting to the MODBus? A USB dongle that acts as a serial port or a physical serial port? After WIN-7 Microsoft disallowed most USB PID combinations unless the owners paid $5k or so

Hi, Trying to move my Mach3/Ess from Win XP to Win10, I get an "Error triggered" "Art Code 1" and "Art Code 9991" at the startup. If I create a new profile by cloning my working profile, everything

I did that on my lathe. I couldn't work out why the finish was so bad. :) Cheers, Peter -- ----------------------------------------------------------------------------- Web
