  2. Re: Y axis offsetting itself at each depth pass ?

    I have done a simple test, I have written a simple GCODE file where I mark down a point at Y10 then another one at Y240. Then I make 10 back and forth travel between those points and mark them down...

  4. Y axis offsetting itself at each depth pass ?

    Hello,

    I need a bit of help to troubleshoot a problem I am encountering. I have built a 3 axis router type CNC running with LinuxCNC, it's really a XYZ traditional router.

    Re: Choosing the right stepper motor ?

    Thank for your reply.

    What is the influence of voltage on the stepper ? The torque ? The torque/speed ratio ?

    Because they specify torque like a constant on spec sheet. I would like to run them...

    Re: Best bearings for BK12 support

    Yes it's a small desktop CNC (320x220 working table). Commercial one I see generally use 12mm thread with 16mm linear shaft. I used one size above for security (16mm thread with 20mm linear shaft).

    Re: Best bearings for BK12 support

    Look like in the size I want (12 / 28 / 8) they are always 15°. The bigger they becomes the bigger the angle (30° than 60°)

    Re: Best bearings for BK12 support

    Of course, all proportion must be kept. I am building a small desktop CNC to mill aluminium so I try to avoid 0.1mm of backlash but I am not trying to go down to 0.01.

    Re: Best bearings for BK12 support

    Thank you for your reply Craig.

    I was aware that angular bearing have a direction of mounting, like face-to-face, back-to-back, .. But I didn't know they had matching pair.

    What do you mean ?...

    Best bearings for BK12 support

    Hello,

    I am building my first CNC and start recieving linear motion pieces from China.

    I have got one of my SFU1605 kit and I noticed that I have got nearly 0.1mm of axial backlash on the BK12...
