Hi Mariss,
Can you solve my problem.
My gantry is ssay 50 kg. on dual Y axis slaved 2.2 Nm motors on 36 V, on 1605 1 start ball screws fixed and rotating nuts by belt drive.
I want to keep the ball screws. But the motors start missing in cutting at around 2200mm/min.
Can i upgrade the motors to 4 Nm and drive by gear ratio 1:2. Thus speeding up the travel to 4000 mm/min. The torque will be halved but it will be still enough ?
Motor will be at just 400 RPM thus using the low RPM high torque range. But due to ratio of belt drive 1:2 the Nut will be at 800 RPM. 5 mm lead will give 4000 mm/min. ??
Or should i go to 8 Nm motor ?
