Mach4 General Discussion / Re: Line 0: Zero Radius ARC
« on: July 27, 2022, 06:02:50 PM »
By the way, can I just take the G18 as I don't see how it does anything but confuse the issue?

The G18 is likely necessary for the arc down move in your program. I'm guessing your CAM software is using that to avoid a straight down Z move into the work. Lots of times CAM uses ramp down or helix down. Maybe you could check your CAM software and use a different method to move the Z down. Or put a G17 in the line after the G18 line just to see if that's it!!! If you could fix it in your CAM you'd avoid hand editing Gcode, something modern folks seem hate with a passion!!!

I don't know why it stops halfway thru and not earlier, but what is that G18 line doing? Arcing down in the Z, looks like. Switching the plane to XZ and never switching back to XY? First thing I'd do is put a G17 in the line after the G18 line. Still doesn't explain why it gets as far as it does without burping as there are no G02/G03 moves in XY which would require the plane to be switched back! I'm mystified.

Mach4 General Discussion / Re: part zero

Move to say the X position you want to be part zero and click Zero X next to the X DRO. Or am I missing something? You can also move to a known distance from where you want part zero, with an edge finder, for example, and click in the X DRO and enter a number, say half the edge finder diameter.

Yeah, I removed it from left up but have not tested yet. I can do that later tonight.

You might have to change the left up script to call the original RefAllHome, but I s'pose that's obvious.

One thing for sure, it's not G54s fault. Something, your RefAllHome script or something, is telling the machine to move. The telling thing is the F30 in that line you "suspect". Nothing would put F30 just pulled from thin air.

I'd go into the Mach4Hobby directory, find screenscript.lua, open it in Notepad or something, and search for the exact line that's moving the machine.

Just remember you can't edit screenscript.lua, it's compiled every time Mach4 starts from all the places Mach4 has scripts. You'd have to find where it is, screen load script, or whatever.

Like SwiftyJ says, package your profile and post it here and maybe someone can figure it out.

Your mention of SCU suggests there is a Smoothstepper in there. Is that the case? Have you tried Warp9td forum? If Andy can't solve this, nobody can. I'd be a bit worried about Mac and Boot Camp, actually, but Andy will know!

Mach4 General Discussion / Re: upgrade to win 11 start problem
« on: April 28, 2022, 08:58:01 AM »
I have two computers running Mach4 on Windows 11. Both are old pc's that don't officially "qualify" for Windows 11, it was "forced" on them. They both work fine, both are on my local network and the internet (gasp!). I didn't do anything out of the ordinary to get them to work. Windows 11 is really nothing more than a feature update to Windows 10. I'd look elsewhere.

For future seekers.....

The answer is here:


What surprises me most is no one here knew this work around or apparently had even heard of it!!

Mach4 Toolbox / Re: Error during load screen element
« on: March 31, 2022, 09:15:46 AM »
Is the ESS plugin IN the errant folder?

Maybe try renaming Mach4Hobby so something else, reinstall Mach4, copy your license, plugins, profiles, screens, macros, etc. into the relevant folders. That would at least fix any folder discrepancies and anything that got corrupted somehow.

It's not a Mach3 set is it? Won't work if it is. Otherwise, don't know other than the set file is corrupt somehow. Did you create it yourself or download it somewhere? Mach4 screens aren't as prevalent in the wild as Mach3 screens were:)
