Hi,

I'm currently finalizing the migration of my CNC computer (pentium 4) to a more modern computer. I'm mostly done instead a few things which are not working properly yet. I have issue with my spindle speed. I have already put back pulley configuration in the new computer. When I start the spindle by pressing button on Mach3 interface or using M4 command, the spindle start but it is turning really slow ( around 200 RPM). When I try to increase spindle speed I receive one of the following message

-PWN Bumped to minimum setting
-Too fast for pulley Using Max

My current pulley setup is : Min speed : 1700, Max Speed 3500

Any recommandation

Thank you
