Aluminium Extrusion Router Build

No 3Nm won't be enough for 2 screws but would if had motor on each screw. Single motor you'll need 6 or 8nm nema 34.
I've used these on couple of bigger machines, nice drives and motors and never had any issues.

Hi Jazz, that Lichuan drive does look very nice, if I go down the nema 34 route instead of twin motors on the X axis. For the nema 24 motors I was looking at the Leadshine CS-D508 drive which appears to be very similar to the Lichuan LCD375H drive or maybe the Leadshine ES-D808 which I think is similar to the Lichaun LCDA808H that you used. On a side note I wouldn't mind supporting UK companies like Zapp but the price difference is huge. From Aliexpress I could get 4 ES-D808 drives and 4 ES-M22430 motors for under £600 and from Zapp the same price is nearly £1200! Even if you get charged £100 from customs this is a no brainer to buy from China. Even a CSMIO IP-S is roughly £150 cheaper if you buy it directly from CS Labs, and there is no customs charge as it's from the EU. I've got another small question, how much distance does the motor shaft have to go into the HTD pulley. If I used 15mm belts and pulleys which are approximately 25 to 30mm wide, if I loose 3mm to the mount would there still be enough shaft length to securely hold the pulley?
