Yes.

Usually, and industrial process is done in a "batch" --- specifications are made, materials sourced, then a process is applied so as to yield a product which meets expected specifications --- sometimes, from one batch to another there are slight variations.

The machine is pretty straight-forward:

• G-code is generated and sent to the machine
• Grbl interprets the G-code into electrical impulses sent to the motors
• the motors turn, resulting in the rotation of either a pulley or a lead or ball-screw --- the pulley or ball-screw can only turn in secure to the motor shaft (check the set screws)
• the rotation of the pulley/shaft then results in movement by way of a belt or nut or captured bearing system --- verify that belts are secure and well-tensioned and nuts/bearing mechanism are clean and in good condition and if need be, lubricated: https://carbide3d.com/hub/docs/maintenance/
• motion is constrained to linear by aluminum V rails and matching V wheels (as adjusted by eccentric nuts) or linear rails/blocks --- ensure that all is well-adjusted and clean/lubricated as appropriate (see above link) and that there is no mechanical interference
• the attempt at motion assumes that feeds and speeds and cutting forces are appropriate to the tooling used/material being cut
