I'm not sure about micro stepping or how aNd where to chnange it. I cannot understand why the step values would be different. The more moves the machine does the more "out" it is. Machine never returns to 0,0 always slightly off. The x and y stepper motors are the same but have different step setting values. I have tried most all of what you recommend but I feel my machine has different issues.
We are trying to determine under what conditions you lose steps or if another problem exists that looks like lost steps. If no steps are missing during jogging then try a sample cut.
But don't change too many things at once since we are troubleshooting. We want to know if each axis misses steps or only one axis. Repeat a similar test for each axis one at a time. Does it lose steps? When? Maybe its an acceleration setting problem? Motor resonance? If this axis seems normal then do the same test of the same axis faster and faster, until you reach your designed jogging speed. if your axis can travel 25" then try for 20". Then I would jog one axis a given distance slowly and measure whether it did, preferrably close to the axis limits.
Alibre atom manual software#
Then ensure that your software is correctly set according to whether the pulse is inverted or non-inverting and of the correct pulse width. Know what the pulse requirements are for the STEP/DIR signals. Also check for any lose or poor connections to your motors and power supply.Įnsure that your PC-driver interface is properly working. Also ensure that you have a good working power supply that can handle your motor loads.
Alibre atom manual drivers#
I would ensure that my motors are correctly connected to the drivers as per driver manual. Secondly, I don't know your system.įirst I would make sure all my axis can move smoothly without binding when turning the lead screw by hand. Well, I don't know how much help I can be since I don't have a running CNC. I would really appreciate some help, thanks
Alibre atom manual manual#
I have tried many things right down to taking the machine apart, reading every scrap i can about step loss, pouring over the manual (i found different ones for the same machine that say different things (hows that possible?)) Im not sure what else to say so if anyone has any ideas please ask me the questions that may get to the bottom of what is going wrong. I was getting oval circles and the 'tuning' helped but i dont think its enough. Its like the machine keeps on losing steps and not returning to x0,y0 A lot!įinally after lotsa research and head scratching i slowed the feed rate down. i was pushing the machine too fast, as recommended again in the manual but that just made the axis stall. I have tuned (i think) my machine and the stepper motors are set to different values for x and y.
Is there anyone out there can can help me? i started with motor issues later progressing onto software issues, thankfully i think have most of them licked but still im having problems. I am a new newbie despite trying for over a year to work out my cnc 6040 machine.
