Thank you Master Hood,

Works Perfectly. You are too Awesome!!

Great. Thanks a lot. I'm going to try to find those things asap!

I often jog around with the arrow keys and the Page Up/Page Down buttons.

Those times when I want to ease my spinning cutting bit down to the surface level of a workpiece I lightly touch Page Down a few times. But when I am .03 or .02 inches away from the surface I cannot quickly enough bump the Page Down without the cutting bit plunging below the surface level. I want to be able to tell the machine to go down by a specified distance.

Is there some way in the Mach3 interface where I can simply type in G00 Z -.02 to command the machine to drop down .02 inches?

If so, where do I type this in? ~Or how else can I jog down by these tiny, specified increments?

General Mach Discussion / Re: Jog Speed versus Move speed??

I am using an old proprietary software called Partworks that came along with a shopbot. These are v-grooves. The software was made by Vectric. Then I use a second software that translates the shopbot gcode to MAch3 gcode.

10 years ago when I did these types of files with a shopbot the machine would race through these types of files. With shopbot I was able to set the Jog Speed and Move Speed independent of the gcode. With this Mach3 machine it is moving like molasses with code generated in this manner.

With a line like the following (that you previously referenced) Is the "F 1.7" just setting the speed for Z, or for X, Y, & Z? When I scan over the code for this file. There are only these occasional "F 1.7" at the end of lines like this. I think they are just trying to ensure the machine slows down on occasional plunges. Since this software was configured for shopbot. I think the code-generation assumes that the operator's shopbot settings will speed up the cut speeds other than these occasional speed-defined-in-gcode plunge rates.

I am hoping you can tell me how to just set a faster speed for the X & Y, in the code and/or in the Mach3 interface settings so I can get it to move through these files faster. Otherwise I'm in bigg trouble!!

As it is the plunges are slow, the jogs are okay, but otherwise the cutting drags a long at a tiny fraction of what it should be.

Thanks a lot. Do you think 1.7 is the ipm? Can you say how I would enter a speed for the x & y in a file such as this?

When I go into "Config:Motor Tuning and Setup" and change spees it only affects the Jog speed. How to change the move/cut speed in Mach3?

The speed is not set in my cut files (I assume it is possible there), but of course, don't know how to do that either.

Here are the 1st few lines of code:

('Tool Name   = V-Bit 90 deg 1.125")
G00 Z 0.7874
G00 X 0 Y 0
G00 X 0.240669 Y 0.250669 Z 0.2362
G01 X 0.240669 Y 0.250669 Z -0.240669 F 1.7

YESS!! It worked! Exactly. Thanks a lot.

I'm moving this machine the first few times... and am using Mach3. I starting cutting some wood, v-carving-type stuff. It seemed to be going to slowly so I stopped. Then I sped up the 3 axes' speeds. When I went to restart it I may have accidentally inadvertently had it start from an unfortunate spot.

It did a clunky thing then began to bury its router bit in the throw-away mdf tabletop. I hit the emergency stop. But then, when I tried to restart it, the Y axis was moving in this really clunky fashion. I thought maybe one of its stepper motors quit working so I disconnected them to see if they'd spin properly when I told it to move in the Y axis. They both spun fine.

Then I thought maybe it was because the rack and pinion was dusty/greasy. I carefully cleaned. Maybe it was slightly better, but still very clunky, not smoothly gliding back and forth on the Y axis. So then I thought maybe the two Y axis cogwheels were out of sync with each other... that maybe the Y carriage was binding. I dropped one Y-axis cogwheel, then rolled the carriage back and forth a time or two. This was my first & only time to do this. But it seemed to roll fine. I re-attached the Y-axis cog wheel then told it to move in the Y axis with a Mach3 command and it still was struggling to roll in a terribly clunky, miserable fashion as I hit the arrow keys on my keyboard trying to make it roll back and forth. Any ideas?

Here's a video of the Y carriage rolling back and forth in terrible, KLUNKY, struggling manner:

General Mach Discussion / Spindle, spindle, please turn again...
« on: March 01, 2015, 08:22:45 PM »
I have a heavy-duty cnc (+ Mach3) machine with no paperwork. I got all the axes moving and calibrated. The spindle would spin when I connected power to the control box. While I realize Mach3 can control spindles, I was okay to just turn it on separately, thinking that was easier.

Yesterday I had the machine mill a fancy, but engraving in wood to test my ability to operate Mach. This evening I was going to surface the table.......BUT........

Now the spindle isn't spinning when I connect power to it!! The H200 and the little STOP light are flashing on the VFD (shown in here in a photo). It seems if I knew:

a.) how to tell the VFD to resume spinning, or
b.) if I could tell the Mach3 to quit interfering with the VFD resuming spinning (IF THAT'S WHY THE VFD is not spinning today)...

then I'd be home free!!! I push the RUN button on the VFD and that doesn't do it.

Does anyone have any idea how to get my VFD spinning again??!??
