Re: ELIMINATING NO-OFFSET HOLES

Dwell is the length of time from when the torch actually fires and it actually starts moving in XY. So any delays or plunge time adds up to a pierce that widens out looking for more metal to cut Its difficult to get zero divots because its a fine line between leaving no divot and a bad pierce. To Mo...

Re: Help with end of cut problem

Also if you are using the MACH3 THC logic there is a setting for THC Rate (or there should be) that sets the velocity under THC. The lift at the end of a cut is a distance and if you are losing steps DURING a cut it will think its higher than it really is and just sit there (or worse go down instead...

Re: Delusional Designs: CAUTION

One of the things builders sometimes overlook is that you can take a section of the table and build a "well" that can have the rotary axis below the normal slat level and increase the diameter of the rotary cut and the clearance by several inches. So even if you just have 6" of gantry...

Re: Adding scribe height question

An air cylinder is not a proportional linear motion device. It either is fully extended or fully retracted. There is no way for it to "know" where the material is. You control the downforce so the material stops it from going all the way down. Now, if you are going to use an engraving tool...

Re: needing some advice

Air plasma is not a precision cutting process . The flame is "floppy" and can bend . There is some taper to the cut . The cut edge will not be a finished edge . Accuracy (on a good day with all the planets aligned and new consumables) is only about + or - .015. Kerf width varies with the a...

Re: Z-axis issues

While it won't hurt to put a larger motor that draws more amps on an axis because the driver will limit current its not a good idea to put a smaller motor on an axis setup for a motor that draws more current. If they are ALL G201x the max current is set on each one with the DIP swtiches. Get the man...

Sap in one of the other motors....if it still does it then swap in another G201X. If it still does it its a signal problem. It sounds like either a motor coil is not working (or nor making good connection) or the velocity and accel are causing the motor to stall. Best way to narrow any problems down...

The M22 only needs to be there if there are more than one S command with no motion between them. Its because the S command has to be stuffed inot the Speed DRO and MACH has to read it and translate the action in the Plugin. The code needs time to do that and if there is nothing happening it overflow...

Do you mean actually power up the motors? Being able to do that from software seems to present a safety hazard. I can see being able to shut down from the keyboard and E-STOP but kinda risky to power up from a hot key (?)
