General Mach Discussion / Windows 10 update causes erratic movements
« on: March 02, 2018, 01:11:22 PM »
Hi All,
I am having issues with my small cnc mill. I teach at a school where we updated to new 64 bit computers this year. When I installed Mach 3 onto the new computer and used a UC100 usb controller. Everything has been working fine, until a windows update installed. I went to cut a 2D pocket out and in the middle of the process the machine plunged into the part about 1/2" when the plunge was set at .06" for each pass. It was totally random and the machine when reset worked fine until the next time I loaded a part. I set the z at .5" above the part to test it and when I did a MDI G0 Z0.5 z moved up to the top of the carriage and crashed. So I went to the settings page and tried to check the calibration of steps. When I selected X and move 1 unit the machine traveled the whole length of the table???? Motor steps are still what they are supposed to be, yet every time I load mach 3 when I first open the program movement is fine 1 to 1 ratio. Then when I load a file it wacks out and crashes. I have tried several files that have never had issues running and they do the same thing. Any suggestions would be appreciated. Thanks.

When I use any of the wizards in Mach 3 the machine does not move the right distance after I use the wizard and post the g-code. It is driving me crazy. I have to close the g-code file, close the Mach 3 mill program and restart it and then when I tell the machine to move one inch it moves one inch. So I go the the wizard and select Rectangular pocket and set up all my dimensions and when I post the g-code 2 things happen. 1st my coordinates are changed from zero's to some arbitrary values. 2nd when I jog the machine it reads that about a 1 inch move as 0.02". Has anyone suffered this before? ( and yes I have the wizard set to inches when I set up the pocket)

General Mach Discussion / Can't send email to tech support

Hi All, I sent a email to tech support and got a reply this morning. They didn't answer my question, instead they asked me a question. So when I went to reply to the email. I got my email back as deliverable, "email quota exceeded". Have any of you experienced this?

Mach3 under Vista / Mach3 turn not running but mill is
« on: August 13, 2016, 11:04:14 PM »
Hello,
I'm looking for some help with my Mach3 turn. Here is the situation. I have a 4 axis CNC that I built myself and am using Mach3 to run all. I have gotten everything tuned in for Mach3 mill. That is to say I can set up and run G-code programs with the mill and it works perfect. So I wanted to start using the Mach3 turn program and I set everything up just the same as I did in Mill. The ports & pins inputs and outputs are the same. The motor control is the same.....but when I hit the reset button nothing happens. It is as if the software isn't reading the controller. Any ideas?

General Mach Discussion / Cant find DXF import button
« on: July 30, 2016, 01:03:28 AM »
Hi All,
I am looking for the "DXF Import" button that is suppose to be available under the File tab. I only have, Load G-code, LazyCAM, Close G-code, exit. I also looked under program files and didn't find it there either. I wanted to try the Bitmap import.

 I found the instructions in the Mach3 manual page 8-6 section 8.4.1 it says "The import filter is accessed from File>Import HPGL/BMP/JPG and the JPG/BMP button on the dialog.
Let me know if you know how I can find this file.
Thanks
Cary

General Mach Discussion / newbe with 4th axis problem
« on: July 22, 2016, 07:50:42 PM »
Hi, could I get some help with my 4th axis. I built my own cnc 4 axis machine and am using Mach3. I have followed all the help many of you have posted on how to "tune" my 4th axis rotational head. I got the steps right for my motor it is a nema 23 so 200 steps per/rotation. it is mounted to a 3 jaw chuck and the ratio is 6:1 (motor turns 6 times for the head to turn once). So the steps per/rotation is 1200 200 x 6 = 1200. So I set my "A" axis motor tuning to 1200 and the motor turns fine. I accelerated it to the best I could and all that is okay.

So here is my problem. When I go to MDI and input G0 A10, the head runs for about 8.5 rotations instead of 10 degrees. Help!!! Please!!!
