I apologize if this has been asked and answered but searching did't turn up what I was looking for.

I just physically hooked up a laser cross hair to my machine and it is connected to the output port 32 on my controller.

Using ger21's 2010 screenset there is a button for using the cross-hair but I'm still new enough at this I have no clue which output  this button is trying to use.

When i looked in the ports and pins setup I obviously have many choices to map the pin to under outputs but want to make sure I choose the one I need the button to power.

Actually now that I'm thinking it through as I type I'm guessing the cross-hair button only tells Mach3 to reset the DRO's to the coordinates of where the laser cross-hair is pointed so I need to figure out how to map turning it on and off to a key but I've no clue.

It is currently mapped to Output5 .

Thanks in advance and thank you so much for all the help you guys give on this forum.

Nothing has changed in my hardware setup. I was having weird glitches in macros so uninstalled Mach3 .066 (deleted folders and even cleaned the registry to be safe) and reinstalled. I re-did my entire configuration from scratch from screenshots I took of all menus so no corrupt xml file to mess me up.

When I turn Mach3 off my machine does the "clunk" so I know it is getting power from the controller card.

Sergey at KSILabs has been trying to help me work through it and nothing he's suggested has worked.

Hardware was working just fine before and I swear I didn't touch it.

Have switched inputs from active low to not just in case and no joy.

I've even uninstalled and re-installed drivers and the PCI card.

Sergey even suggested going back to .062, which is what I started with when I first got my CENTIPEDE controller and it just worked then.

I'm at my wits end. Does anyone have a suggestion? I'm attaching my newly created xml file.

I found the mastercam post processor and overall things are working much better with code MasterCAM puts out but on some files it will start to do my tool change, it will go to the correct X,Y position for the tool change, then I hit cycle start, it will go to the correct X,Y position for the fixed tool check plate and start to descend but a second later will stop descending with t ding sounding from Mach3 and sit there showing Probing for Z Zero... but nothing happens until I hit either stop, at which point it will flash "Error on line 147 - Application defined or object defined (and then I can't see the rest of the error)" or if I hit Cycle start again it will start descending but will try and push through to the center of the earth.

It will do this with some of the cut files I create but not others but they are all created using the same settings in the post processor file; at least I think so.

Any ideas?

Hello Everyone. I am absolutely loving ger21's screenset and being able to do tool changes but in my first larger cut I'm having weird issues.

I'm using MasterCAM x5 to create the code and I know there are a few quarks like I have to change the very first G90 in the code to G91.1 to make it not error upon loading in Mach3.

The other issue I had was there was an M01 call right before the 1st real tool change (yes there is an M6 at the start but that works flawlessly) and Mach just stopped at that. So I removed the M01 and it seemed to work. Since the spindle was 44" away it came back to the front, let me change the bit, did it's re-zero to the fixed tool change touchplate then went all the way back to the far end of the piece where it was.

Then instead of starting back up a strange menu popped up with a bunch of check-boxes and things about starting the spindle and getting up to feed rate so I hit ok (this wasn't the usuall just hit cycle start again to get going).

Did that and then the spindle came all the way back to the front and didn't do anything.

I'm guessing it is something in MasterCAM's creating the gcode causing this but I'm not sure what.

Could someone take a look and let me know what I need to fix? It's probably the lines around 150

General Mach Discussion / Ideas for a jig to do Set Steps Per Axis?
« on: September 17, 2013, 12:36:30 AM »
I find my X axis gets off ever so slightly when doing large cuts and I try changing cutters so I want to do a long distance auto setup of the X axis using the "Set Steps Per Axis" button on the Settings screen but I'm having trouble figuring out a good way to do this. I did it when I first got my machine but with only 6" or so. My machine is 11' long so I have a lot of distance I can play with. Does anyone have pictures or even a good explanation of what they used for a jig etc to accomplish this?

I recently received a Chinese CNC http://salecnc.com/catalog/product_info.php?cPath=21&products_id=59&osCsid=gosj62io17t8qoku4tp0ti1704 the XJ 1325.

I have switched over to Mach3 because of the endless issues I was having with their software and controller. I switched using a CENTIPEDE controller etc http://ksilabs.com/ and Sergey has gone above and beyond helping me switch over the boards, even helping me reprogram my VFD to work properly and I am 90% of the way there.

The problem I am having is I'm definitely losing steps so I need to tune but the Chinese salesman knows almost nothing about the technical aspects of the components. He was able to give me the steps, at least he says they are the right ones, but beyond that they are no help. And when I ask about Step Pulse and Dir pulse they have no clue what I'm even asking.

So far what I know is I have:

X & Y steppers are 96.01536 (they called them pulses)
I have two motors on the Y
Both X&Y motors are 86BYGH450B-060-15J and are 1.8 deg pitch
The Z step is 160, 1.8 deg pitch same motor part number but ends at the B. Nothing I can find shows this part number with nothing after it but the motor shows it is 4.3A 0.55Ohms  6.0mH

Sergey at KSILabs modified my XML and it is working a little better than what I had but on the last thing I tried cutting the Z cuts kept getting progressively deeper and suddenly plunged down about halfway through the board.

Any help at all would be greatly appreciated. I've had this ,machine for 3 weeks now and haven't been able to successfully use it yet.
