Hi there,
Im loosing steps on my X axis at a certain line in the code. I'm running mach3 on windows 7 with a printer port to a breakout board then to individual cards. My stepper motor will make a buzzing noise just like if you were to try to run you axis into an end stop. it lasts for a second or two. It doesn't do it every time but almost every time. I made 7 pieces and it did it on 5 of them.
I have 1200 OZ motors, ball screws and linear rails. I removed the cars off of the rails and checked to make sure they were not clogged with sawdust the cars and the gantry head moves easily along the rails. the ball screw also rotates freely.
I'm cutting slots with a 3/4" bit in Ash I plunge down 3mm at 190mm per minute, then it travels to the end of the slots and plunges again.. travel speed is 1800mm per minute. My acceleration is set to 120mm per second in ports and pins. It happens right after a plunge as it starts to travel it makes it about a 1/4 inch then hangs up. there are 9 slots and it only does it in one slot at the same depth and place. I dialed down my acceleration and speed. same thing.
I run all shielded cable...…. power supply in in a separate box from the BOB and control cards...…
Here is the lines of code where it happens.
This is in mm

Z-12. F190.
X417.014 F2000.
Z-15. F190.
X436.014 F2000.
Z-18. F190.
X417.014 F2000.
Z-21. F190.
X436.014 F2000.
Z-24. F190.

Any suggestions would be great!

Hi there!
My Mach3 CNC is not running at the posted feed rate. My motors are tuned for 1900 mm per minute velocity and 270mm for excel. My post script is telling the machine to run at 1800 but it only cuts at 1673.95 mm
Per minute? Even if I over ride the setting it still only cuts at 1673.95mm
I’m using Fusion 360 for the cad cam and post processing.
My Mach3 screen shows that the program is supposed to run at 1800.
Any thoughts on this?

Thanks
Glen

Mach3 under Vista / computer screen goes black when running mach3

Hi there,
I'm running a windows 7 computer with stand alone video card, been running his particular computer for a couple of months now.
but all of a sudden today after about say ten minutes of running a jobs with mach3, the operation stops cutting and a second later the computer screen goes black and will not respond to keyboard or mouse. i have to unplug the computer, reboot and start all over again only to have it happen again 10-20 minutes later.

I'm wondering if it is my Video card packing it in?

Thanks
Glen

Hi there,
I’m running a desktop windows 7 32. Bit. Multi core processor, stand-alone video card and printer express port card With a LPT port breakout board.
If wondering if I tell my tool to run at 2000 mm/min and in my ports and pins under motor tuning I have the motors speed set to 1998 mm/ minute will this cause miss-Steps every once and a while?
I use Fusion360 to design and make the tool paths gcode. I bumped up my cutting speed from 1900 to 2000 recently. Im missing steps as much as a deviation in one shot of 10mm
Right when my tool path changes from a 3D Adaptive clearing to a 3D ramping tool path.


 

Thanks
Glen
