General Mach Discussion / Strange problem in Circle

« on: February 13, 2011, 09:34:43 AM »

Hello:

My home made router was unused for a month and last night I turned it on for an urgent profiling work. But circle in my design profiled a strange shape! Please see the picture attached. I've also attached Mach3 config and the Gcode.
Everything was working as expected before and I can't really remember I modified anything in Mach3 by this time.

Kind suggest me the fix.

Thank you.

General Mach Discussion / Leadscrew vibrates in one direction

« on: November 04, 2010, 05:20:00 AM »

Hi CNC experts:

I need some help from your guys.
I have a home built CNC. My leadscrew is vibrating and screaming in one direction for the base axis (I called it Y). Specifically, it is happening from other end to me but not from my end to other end. All other axis's and directions are smooth.

I did some adaptation in different areas, i.e. replaced the rails, reduced the speed & acceleration, nothing really helped. But it did a little improvement after I switched from 1/8th microstepping to half stepping.

Please advice about where to check...

Thanks in advance.

General Mach Discussion / Need info: Mach3 line count

« on: October 18, 2010, 12:17:48 AM »

Hello:

Power in my country is not stable enough. It frequently fluctuates and in some cases even my UPS gets abnormal switchover and due to the fact that PC gets rebooted.

I would like to know if Mach3 writes a log for the line count as it executes. It will really help me to resume the milling from where it was interupted. At this moment it is a big pain for me to identify the line number for the interupted milling.

Any help will be greately appreciated.

General Mach Discussion / Stupid behavior of the PC in Mach STOP command

« on: September 13, 2010, 01:25:42 AM »

I'm badly suffering of a stupid behavior of the PC whenever I press STOP button in Mach3 during curving something. PC just gets rebooted by the stop command in the middle of the job (running). It's a bit freaky to explain because it doesn't happen in regular stop.

For instance, I loaded a tap file to cut something and pressed the START button. Mach3 is doing what it supposed to do and I can stop it anytime without any problem. But I have noticed that my PC gets rebooted if press the STOP button somewhere in the middle (or near to finish) of the job due to an urgent reason or to stop the test run. It doesn't happen if Mach stopped in the begining of the run.

I tried two different PC's and it was the same behavior. For your information, in both cases it was DELL Optiplex 260 and there was just the Mach3 and no other softwares were installed.

Please help me to get rid of this problem. I don't really understand whether it is problem in the PC's or some settings somewhere.

General Mach Discussion / Backlash compensation: config option

« on: September 12, 2010, 07:08:50 AM »

Hey guy's:

I have some backlash in my X and Z axis.
For one inch move, dial indicator shows 1.004" in X and 0.997" in Z axis. So the backlash is 0.004" in X and -0.003" in Z.
How do I configure it Mach3? Appreciate if someone can shed some light on this.
