Pivot-length is a hal pin which modifies the kinematics calculations which are made at servo rate. You can change it's value as often as that.
As long as the changes are smooth enough to not to generate following errors, you should be OK. One way I imagine to do that is using M67 and connecting the analog output pin to pivot-length. ________________________________ De: Marius Liebenberg <mar...@mastercut.co.za> Enviado: miércoles, 21 de septiembre de 2016 15:05 Para: EMC developers Asunto: Re: [Emc-developers] THC with 5 axis plasma That sounds interesting.
