Good morning. 1) I have a question about the C-beam 8040 profile. I am building a small CNC plotter (something like cnc 3080) on 2020 profiles. For the c-beam profile I have a 12mm linear guide and MGN12C carriages. I was thinking about the drive and after the analysis I chose the ball screw 1204. The problem is that my gate is 500mm long. The 500mm ball screw is too short because it is flush with the profile and unfortunately it cannot be attached, and the 600mm ball screw is too long. Has anyone solved this problem, is there any dedicated length? 2) I want to use 0.8 Nm 2A stepper motors and MGN12C carriages for the milling machine. The milling machine is intended for milling small structural elements in aluminum. Does anyone have experience with small machines and could stand out on the topic? Thank you.
