Mach3 under Vista / Change Inches to MMs

« on: May 25, 2018, 10:43:33 AM »

hi all
I'm having problems setting up my machine in millimetres in mach3. I changed the units in Config but when I save and open the DROs are reading in inches. So if I create a new offset for x0 y0 the machine goes to that offset. But if I load a code with a G21 my offset is altered. Previously my DROs were in mm on startup. How can I make Mach3 default to mm on startup?

Mach3 under Vista / Touch off sequence not completing. Urgent help required!

« on: May 23, 2018, 12:40:33 PM »

Hi List
I am running a Legacy CNC router with Mach3 on Win7. My issue is that when I run the program to perform a touch off on the pad the Z axis drops down to touch off, lift off a few millimetres and starts down slowly again to touch off the pad. The activation light comes on and the tol stops. However, nothing else happens - it won't finish the cycle. Any ideas why? I have tried replacing the Macros folder from a good backup to no avail. I am stumped and in dire need of this machine. Please help!

Regards

Mach3 under Vista / Mach3 not controlling motors

« on: May 14, 2018, 04:31:00 PM »

Hi List
I'm running Mach 3 with Windows 7. I had to do a clean install of Win7 and since I did the DRO is jogging but not the motors. That reassuring click I used to hear when PC connected to the motors is no longer there. The two are not communicating. It feels like its a driver issue but I have the drivers installed as they were before. I'm using Smooth Stepper driver. Can someone tell me exactly where they should be just in case. Any help would be appreciated hugely.

General Mach Discussion / Hole cutting code

« on: July 11, 2016, 01:03:13 PM »

Hi
I'm very much an amateur with gCode and have a question. I am trying to cut an 8mm hole with a 2mm bit. Following some study of various YouTube clips I have come up with the following code - trouble is it doesn't work. I am getting an error just before the G3 mode that the arc is different to the size in Line? I can't read it fully on the status window. Anyway, can someone there look at this and tell me what's wrong? Its probably something very basic.
Thanks in advance

General Mach Discussion / Keygrabber query

« on: December 14, 2013, 10:27:26 AM »

I'm trying to set up a games pad to use with Mach3. When I open KeyGrabber I'm getting an error window telling me there's a violation. A new version of the same window opens up at a rate of approx. one per second. Any ideas? I'm using a Mac with Version 10.6.8
Thanks

General Mach Discussion / Homing issue

« on: January 25, 2012, 08:47:49 AM »

Hi
I recently activated my copy of Mach3 but am unsure whether this has anything to do with my problem. When I run the Smart tool Setup and it travels to the home co-ordinates it goes to a completely different area of the machine. I have checked the home co-ordinates under configure/homing limits and they are correct. However the smart tool setup is not driving the cutter to those co-ordinates.
Also, when the tool tries to go to the smart tool touch off co-ordinates they are now beyond the Y axis soft limits.
These problems did not exist prior to my activating the product, but seem to be a settings issue. Can someone please walk me through setting this up?
