hi all
im new to the cnc world... something like 6 months till now
i have build this machine (pic 1) from scrap wood and an old industrial printer parts, orderd some step motors (pic 2) , made the shild for the step motor controllers (pic 3) , made the power sorce for 3 motors and fan from an ATX power box (pic 4)
i made a temporery mount for a pen (pic 5) and attached a pen to the Z axis as a spindel for testing and calibrating steps to the GRBL $100 $101 $102 and since all 3 motors are same and my rods are same i have inputed the same calculation for all 3 of them.
after i have created a G-CODE in form of a CN file on MAKERCAM and i sended to the machine via UGS
the resolt was ok but the problem is that after it finish the job it stay on the last point it finished and not going back to the 0 , 0 , 0 point
anyone can solve this ishu ? any tips ?
thank you all in advance.
