Mach4 General Discussion / Re: Mach4 bug (wizards) - v + 4300

Look for versions of these files with a "mcc" extensions.  The mcs files are from your OLD install that had 5.2 LUA.  mcs files were never supposed to be compiled, but were, do to a misunderstanding way back when.

mcs == non-compiled human readable LUA scripts.
mcc == compiled scripts. 

Delete any non-readable *.mcs files and you should be good to go. 

I can confirm that yup I'm a Muppet.... should have done a clean install and not just installed over the last install

problem fixed

there may be other similar gremlins under the bonnet elsewhere too

yeah, I thought it would be that, but the problem for us mere users is we cannot fix the problem as they are compiled by NFS I guess... or someone else who needs to maintain them of delete them from future releases......

always the problem with something under perpetual development... especially if you change the software version upon which it's based.  I understand completely.... but the expectation is that NFS added them to a watch list of items when the decision is made for lua 5.4, 5.5 etc.... that needs to be done again

probably wants someone to just click on a few of the wizards and see what works and what no longer works as there seems to have been something that has obviously changed and now they no longer can start up.

The following seems to be a fairly common issue (bug) across a few wizards such as the FeedandSpeedWizard , or soft limits config etc

Lua: Syntax error during pre-compilation
C:\Mach4Hobby\Wizards\FeedandSpeedWizard.mcs: version mismatch in precompiled chunk

Lua: Syntax error during pre-compilation
C:\Mach4Hobby\Wizards\mcConfigSoftLimits.mcs: version mismatch in precompiled chunk

thanks Brian, much appreciated, us lathe users tent be be a forgotten minority in the CNC world

Craig, no its not the same thing

jbuehn, thanks that gave me the clue I was looking for.

It is definitely a bug, and it affects all releases from back to

Attached is the screenshots from the Modal Wizard and the status line/ bar from

The wizard also appears to have a bug too....

As you can see modal group 05 says feedrate mode G99 (which is correct), which the wizard says is "R return point", which is a wizard bug...... it should read "Feed Per Revolution"

And then when you look at modal group 10 it says Active GCode "G99.0", this is a Mach4 bug as it should say G99.1 , which is "R Point Return"

These are covered in the Lathe GCode Programming Manual, Chapter 2: GCodes (PDF page 7, 8 & 9)

The problem is its lathe and turning and not many people are probably interested..... hence why it gets missed / not put right.

Seems to work as intended / expected within

G0 X100

Feedrate = 1200 units / min = Axis Maximum Velocity

Any suggestion why the feedrate for ONE axis at rapid G0 would be higher than the maximum axis velocity set for the motors?

Both motors set at 1200 units / min

units set are mm in config.

Simple G0 X100 (or Y100) in the simulator

And the feedrate is listed as 1333.33
