I am wanting to cut mother-of-Pearl material for inlay work.  I am wondering what is the best method to use to hold the inlay while cutting.  I have obtained some bits for shell material and tried to hold the piece with double sided tape.  However, the tape didnt hold the piece rigidly enough and it moved during the cutting process.  Obvious concerns are holding tight enough during cutting but pliable enough to allow separation from the hold down method without breaking the MOP.  Any suggestions would be appreciated.

General Mach Discussion / G Code Skipping
« on: November 09, 2012, 06:17:21 PM »
Hey guys.  It has been awhile since I posted.  I have finally gotten a drawing into Gcode that is fairly simple.  Part of the job is to make a pocket .08" deep and about 2.7" square in a piece of wood with a 1/4 inch end mill bit.  The Gcode starts in the center and spirals out to the edge.  In one of the straight x-axis moves the gantry suddenly stops and the motor makes a sound likes it is skipping.  The next Gcode step is the y-axis move and it continues with no problem.  The x-axis skip occurs in only one of the Gcode lines repeatedly.  I have run the program 3 times and the skip occurs in the same location.  Each time with the wood repositioned on the table.  I have changed feed rate from 160 to 140 thinking that maybe that would resolve the skip but it didn't.  Any ideas? :-)

General Mach Discussion / External EStop Requested
« on: March 06, 2011, 01:33:54 PM »
I have now been able to run my home built CNC router.  I am learning to use Mach 3 and the machine.  I loaded the Roadrunner.tap g-code that came with Mach 3 into the machine and without the router powered the program went through the program without issue.  I put some material in the machine and set the soft limits to the material and started the program with the router running.  About 1/5 of the way through the code the program stops and the reset button is flashing with a message saying "External Estop Requested".  None of the limit switches have been triggered.  I can turn the router off and can reset the program.  Within seconds of turning the router back on the reset light flashes with the same message.  This is with no movement of any of the axis.

The diagnostic screen indicates that the e stop switches are not activiated.  I can manually trigger the estop ligh ton the diagnostic screen by manipulating any of the switches.

The power cord for the router is no where near any of the wires for the z axis or limit switches, so I don't think it is electrical interference causing the problem.  However, since the problem only occurs when the router is powered, I suspect it has to be electrical noise.  I have also checked all of the electical controls and none are elevated in temperature.

Does anyone have any suggestions on how to get around the problem? :)

General Mach Discussion / Mach3 and Windows 7 64 bit
« on: December 12, 2010, 11:00:34 AM »
Hello.  I have just obtained Mach3 and installed on Windows 7 64 bit system.  In a different post I heard from Klaus that these may not be compatible so I thought I would start a new post.  Is Mach3 compatible with 64 bit systems.  If not can the 64 bit system be modified in some fashion.  I found reference on the PC to a virtual PC system.  Does anyone have experience with this problem.  Currently, I am unable to access the LPT port with Mach 3.  I have performed the Driver test with no outcome.

Any help would be appreciated.
