Ballscrew router and G540 steppers | |
If I was to construct a gantry router with a pair of say 4 or 5 ft leadscrews for X-dr and the best steppers my G540 would drive with a 48v power supply. There would be no gearing on the steppers.
What would the performance be?
On paper, based on the ~50ipm step rate it can handle on my Taig mill, that'd be in the ~1000ipm range. But, the required torque and backdriving are totally different things on a ballscrew router on this machine with higher inertia. Then again, it's a G540 drive and those are "good".
I would most definitely like to simply unplug the G540 from the Taig and plug it into the router and save the money of having to get into a servo drive, at least right now. Money's tight and it's a big question of what kind of servo drive I'd WANT, and I'm dealing with the construction issues of the router right now.
I can afford new steppers and flex couplers, since it's way too much work to move the STEPPERS off the Taig onto the router. But, I wouldn't want to be wasting money on this if it's not going to perform.  |
