Hi,
My Name is Mark Lewis and I am new to the forum.Just a brief introduction I have a colchester truimph 2000 under Mach 3 control and I am having a problem with the actual spindle speed DRO that is not displaying the true speed in the DRO.The strange thing is that when opening turn diagnostics the realtime RPM is displaying correctly and if I vary the RPM the speed changes accordingly so I would think that would rule out a hardware issue.I have even tried to disable the turn diagnostics plugin and the result is the same.The version of Mach 3 I am running is 3.043.020 which is not quite up to date with the latest lockdown version.I have also tried various options in the spindle setup but this makes no difference. Has anyone had a similar problem?
