ballscrews vs e-gearing

[oxford]

I am building a gantry mill.

I have two actuators I want to run parallel for the x axis. The problem is that they both have different ballscrew pitches.

I have mach 3, so I have considered running one side as a slave and tweaking the motion to be equal with the motor tuning feature.

My other thought is to find a ballscrew and nut match.

My concern with e-gearing through Mach 3 is that under start-up and over time, missed steps will induce stress and problems.

My concern with matching pitches is cost.

Any thoughts?

Thanks.

How standard are the machined end sizes?

I had a website to the Taiyo actuators, but it gave me some problems

When using slaving in Mach3, all settings for the two axis must be the same.

So the motors would have the same tuning?

Which means if I use MAch3, I need to have the same pitch ballscrews.

:P

Yes.

i got my ball screws from china. they got here before the timing belts i ordered on the same day from the usa.. they will do any machining you need and will throw in stuff like motor couplers if you ask. very reasonably priced
