Frame rigidity and spindle power, then the bed you can clamp to · review
An all-metal desktop CNC with an upgraded spindle on an ER11 collet, 7.3 Nm stepper motors and a 4040 Y-axis profile, sold by SainSmart.
SainSmart moves to an all-metal frame, a 4040 Y profile and larger steppers, which address the flex that limits cheap 3018 machines.
An ER11 collet gives you access to standard tooling. Check the 710 W figure in the table against the listing you receive, since the bullets call it upgraded and give no number.
Soft titanium and carbon fiber appear in the bullets. Dust and rigidity limit a desktop machine long before the list does. Start with wood, plastics and aluminum.
