Buen dia compañeros, tengo un pantografo cnc con plasma y mach3 con thc, cuando corta el thc envia la orden y se ve en Diagnostics como trabaja la bajada y subida, pero mach3 pareciera ignorarlo, esta todo configurado como debe aparentemente, pero es como si hubiera un delay, no lo se
Ya probe variar todos los parametros que se pueden en la pantalla del mach, tambien esta configurado en modo thc, no se si me faltara algo.
muchas gracias

Hi Juki77,

Just for some clarification, are you using the LPT Parallel Port or an external motion controller ?

Tweakie.

Hello, how are you? , yes, I use lpt board, THC UP and THC Dnw are on pins 13 and 12 respectively, both in active low, and on the diagnostic screen when thc works the warning lights come on as thc goes up or down, that is to say that mach3 detects them but ignores them, on some occasions if the Z axis has been raised by order of the thc, but it never goes down, that's why I think I am missing some configuration
Attached XML set file
thank you very much
