Hi, Yes my project was little strange, I made a lot of change, My drivers are 6.5A the drive look like good they are Chinese I was only afraid about motors they look like not the same quality. I use step motor as spindle because I need to control my A axis for grooving for example so like that my spindle is like a full axis The spindle motor has a low speed only 150rpm because it used for stone cutting, I have a planetary gearbox with ratio 1:8 so my spindle speed is around 1200rpm I was thinking that will be ok I will add extra cooler plate in aluminium with a fan to see if it's better
Thanks! Cordialement, Moustapha Elhima +33 6 09 99 21 97 P Penser à préserver l'environnement avant d'imprimer ce message.

What are motor's rated current and actual current set in the stepper drive? How fast are you spinning the motor? -- Viesturs ------------------------------------------------------------------------------ Introducing Performance Central, a new site from SourceForge and AppDynamics.
