Title: Mem map file sharing exception error - ToolDisplay0.dat
Post by: Azalin on March 30, 2026, 01:53:35 PM

I get this error almost every time I click the "View Toolpath" button in canned cycles.

Mach4 Hobby Lathe
Mach4 4.2.0.5036 (latest)

Is there a fix or workround?

Thanks

Probably the consecutive call for mcToolPathGenerate() method is causing this error.

Any ideas?

Nobody's using Mach4 anymore? wow. Anyway I fixed the problem by adding a monkey patch into the screen set. Works well.

I am pleased that you found a fix.

There are still plenty of people using Mach4 it is just that the software developer's support for the product ended way back and many of the regular contributing forum members have just drifted away, possibly as a result.
