building a laser cutter
Posted: Fri Sep 14, 2018 12:03 pm
Hello there,
I am new on this forum.
I started to design my 60W Laser cutter and I have some questions, I would be grateful if you can help me.
The machine will have one Nema 17 stepper for the X axis and two Nema 23 for Y and Z axis, the drivers will be the Geckos G201X.
I'm confused about the steps per mm because I would like to move the axis with 20 tooth pulley GT3 3mm pitch.
When I'm making the calculation (Motor step angle * Sriver Microstep) / (Belt Pitch * Pulley tooth) I've got these relults:
(200 * 10) / (3 * 20)= Steps/mm: 33.33333333, Resolution: 0.03.
Is this ok or I will have a problem, something like error? loosing steps?
If I change the belt pitch to 2mm the result is= Steps/mm: 50, Resolution: 0.02.
I'm thinking to use 9mm width belt.
What do you suggest me?
Thank you in advance,
Nikos
