I have finished my MPCNC everything is square and correctly mount (I think). I first had some issues with the steppers that were just rattling but not moving. It happened to be a wiring issue, that I fixed after some research thanks to this video : https://www.youtube.com/watch?v=bR3853iNaW8
Now everyhting moves but the steppers still doing that rattling noise but as soon as I remove the belt it’s fine. It’s like they are not powerful enough to move everything. I tried the crown test anyway but the drawing is really bad and not precise at all (almost square instead of round).
I am using Nema 17 1.5A 2.4V 1.8°420mN.m with A4988 drivers on a Mega 2560 and a Ramps 1.4 but do you think it’s enough or should I switch to DV8825 and more powerful steppers?
Also, to run the crown test, first I place the gantry on the corner and then I set the Z with a sheet of paper. I hit start, the tool goes up move to go in place and then go down, but way to down so the pen is pushed up.
Do I miss something? I believe it’s a tool setting in ESTLCAM but I don’t really understand all the settings of the tool. Can somebody help me about it?
Thank you for your help.
