General Mach Discussion / BigTexBlue Screen.. modify gcode?

« on: November 01, 2014, 11:25:28 AM »

I'm pretty new to Mach and GCode so go easy on me please..

I'm trying to utilize BigTex's BlueScreen's Auto tool zero and I see that it says that it zeroed in "Metric" when I ran it.

I have 2 questions:

1) How do I edit the GCode in Bigtex's screen for the speed in which it auto zero's, etc.?

2) If I can't edit the GCode can I change it to inches?

Thanks,

General Mach Discussion / How to - code manual tool change?

« on: October 20, 2014, 09:48:10 PM »

So, I'd like to run a single job that incorporates a manual tool change but I must admit I don't know how to make that happen. I was hoping someone could assist me with the process...

Below is the G-Code that has been produced and I see there is a tool change form a 1/4 to 1/8 bit (N258T2M6) but I need the machine to stop cutting, raise the Z axis, allow me to manually change the bit and them home the Z axis using the new bit and a touch off plate.

Any help or suggestions would be appreciated..

Adam,

General Mach Discussion / Charge pump not functioning..

« on: October 12, 2014, 07:57:57 PM »

I have a G540 and Mach3 currently setup with a PCI Parallel port card that I thought had been working well, until I realized I had the Charge Pump "off" on the G540.

After some further testing it appears that either Mach or the Parallel port is not functioning correctly and not generating the necessary pulse for the G540 to pick up.

So, can someone assist me in how to determine what is not working? I see 3 variables here, the G540, parallel port or Mach.. I need to be able to eliminate them but I fear I need a oscilloscope to do so.

Is there another way? I have pretty cool multimeter that is supposed to measure frequency but alas I'm not sure how to use it.. maybe it could be useful?

http://www.amazon.com/Amprobe-37XR-A-Digital-Multimeter-Component/dp/B0012IUYK0/ref=sr_1_1?ie=UTF8&qid=1413158160&sr=8-1&keywords=37xr-a

I'm hoping other have run into similar issues so I'm open to suggestions..

Thanks.

General Mach Discussion / Homing and Home Offset

« on: February 01, 2014, 08:58:18 PM »

I've got my machine homing quite nicely now thanks to the members but I have 2 questions about the normal operating procedure and the Homing Offsets.

When I click on the REF ALL HOME after a reset my machine will home all 3 axis as well as run a home offset.

1) Should the normal procedure for the initial start up of the machine be to REF ALL HOME and if using the "Machine Coord's" click that button and zero all the axis? Does the Machine Coord's always need to be reset at start up?

2) My machine is set to inches and my Home Off. in the Motor / Soft Limits is set to 2.0 for x/y/a and -1.0 for z. After the REF ALL HOME I am assuming this is when I should see the offsets put into place however they are much smaller offsets than I have set, not sure what is not correctly setup, any ideas?

Thanks.

General Mach Discussion / Questions about "Soft Max", "Soft Min", "Slow Zone" and "Home Off"..

« on: January 04, 2014, 06:41:37 AM »

First post on the forum so go easy please.

I'm a newbie to the CNC world and have some rather simple questions I hope about homing and limit switches when setting up MACH.

- Are the "Soft Max/Min" set from the distance of the Limit switch or Home switch?

- Is the "Slow Zone" the distance before it hits the Limit switch or the Home switch?

- Is the "Home Off". used to set a distance from the physical Home switch?

I realize that MACH enters default settings but I was hoping someone might share what their settings are and how they came to those conclusions.

Thanks for any and all input..

Adam,
