Ba da bum!
I think you just may be as corny as I am.

Discovered that I had fat-fingered the safe start line, putting in G17 instead of G18. That fixed the arc being missing, but revealed that the postprocessor is using G3 when it should use G2 and vice versa.
I *think* I have that fixed, but I'm going to have to design a part with a bunch of different profiles and make sure all the arcs are in the right direction to be sure. The part of the post that controls this bit is crazy complex.
I haven't had any probing problems with the pokeys57CNC make sure you are wired to pin 19 on pokeys and on some of the older boards you need to add a i think pullup resistor to pin 19 but been a while and don't remember for sure, the only drawback for me is it won't work with more that one probe connected..Wow. Good information. Thanks!
That makes sense and I think you did the right thing but Why does a G02 go CCW and a G03 go CW? Is it because the tool post is mounted front and a Fanuc is mounted in the rear? I guess i would have thought that those two commands are set in stone. If it is a case where it is tool post dependent there would be an option check box for forward or reverse tool post.It depends on which side the tool post is and which way the spindle turns. It is more machine centric than controller centric as the machine tool builder decides where the tool post is and the spindle direction. Meaning all Fanuc controlled machines will not have the tool post mounted in the rear. However, most CNC machines have the tool post in the rear or they have both a rear and front tool post. And most CNC lathes determine the spindle direction as if looking at the spindle from behind the chuck too. Mach3 could not handle a dual tool post machine and it did not adhere to any industrial standard. But even Mach 3 defaulted to a rear tool post for a CNC lather. However, most lathes that Mach 3 ran were manual lathe conversions that had the tool post in the front, hence the swap G02/G03 checkbox.
machDir, rc = mc.mcCntlGetMachDir(inst)
myPmcObj = require(machDir .. "/myPmcObj.lua")
myPmcObj.PlcCycle() -- this will cycle that PmcObject one time. :)
Nice to meet you.
I am migrating from Mach3 to Mach4.
I also got an error when I loaded Gcord that worked on Mach3 into Mach4 as it is.
I gave up. I use FUSION 360 for CADCAM. When generating a Tap file, Mach4 is specified and the Tap file for Mach4 is used.
Tool paths are displaying better.You have to edit the screen set and change the tool path's properties. The "Follow Mode" property, to be specific.
Is there a setting or an edit to keep the tool paths from moving in the window and have the cutter position move. The tool paths moving like that gives me motion sickness.
