How do you mount 3 grub screws motor mounts an keep them straight?

Don’t mount them at all. Get some better mounts.

Even if you get them mounted, they will likely fail in short order.

That being said,

Alignment – the best way I’ve found to perfectly align belts is

• get motor mount (without motor) snug on hanger, then loosen a tiny bit so it moves
• install wheel and pulley with no speedring (washer) between the hanger and inner bearing.
• push motor mount flush up against wheel pulley so they are touching each other
• keep those held tightly together while you tighten motor mount clamps
• make sure mount is flush against, and touching, the wheel pulley, and there is no gap or misalignment
• finish tightening mount clamp all the way
• make sure again that mount is flush against, and touching, the wheel pulley, and there is no gap or misalignment
• when you’re all done, take the wheel and pulley back off, add a single 1mm speedring (washer) and just like that, the pulley will be perfectly aligned and 1mm away from the motor mount plate
• if you need it further away when you are doing tensioning, then add more washers
