Hi, Hopefully, anyone can help me to solve my cnc machine problem. Now i'm using sherline milling machine with mechatronic stepper driver and linux emc2. The cnc problem is when i program it to draw a round circular shape the horizontal lower part of the round circle is alway 0.5mm diameter shorter than the upper round circle. The end point of the circle would not link with the start point. Below is my testing gcode: % g21 G91 G00 x0 y0 G02 I-10 F45 G00 X0 Y0 % For cnc configuration. both the x and y axes lead screw pith i put 2 mm/rev. I have set BACKLASH = 0.50 in EMC2 .ini file but still would not solve the problem. So, can anyone help me to solve this problem. Thanks.  |
