Topic: SD4 X motor pulley grub screw removal?

Greetings,
So I have been having problems with the grub screw on the X motor pulley for couple weeks now. After breaking two 1.5mm hex screwdrivers and ordering a 5pack of hex keys. I cant seem to loosen it and pretty sure its now stripped.
Is this screw glued in??? haha I guess the only other option is the drill it out, but if its glued in, ill put myself in more trouble.
How did others who did the lawsy carriage upgrade flip thier pulley? buy a new X motor?

You can try a star style bit that fits.  They bite much better than the hex style.  Then you just use a channel lock pliers to press it in and use 1/4" wrench to turn it.  They have been super glued in by SD.  I have yet to have one beat me.
