thanks, Charles. I will also take a look at the Machine control definition suggestion.

The 1" absolute Z clearance distance is too short for me for tool changes. What is the "search" line for me to change this value in the postprocessor.
Thanks

Bargain Basement / will share my 15x30 k2cnc router near NYC

« on: April 03, 2017, 07:34:06 AM »

When I moved to NY(brooklyn), finding a good place to run my cnc router one day per week turned out to be a major issue. Workspaces available are simply too expensive, and most they are not suited for cnc routing.
I cut only thin mdf for my hobby/small business activity.
Since I need my cnc only one day per week at most( usually sat or sunday), I'd be happy to share it with someone who wants to have one and has the space for it.
I'd be happy to train the individual so that he or she can run it freely.
The router is ideal for hobby type of work, has a Mach 3 running on a laptop and comes with a nice dust collector.
I am a retired individual, so I don't do this for a living. I like to stay busy, and enjoy cad cam work.
I am currently renting a small workspace, so the offer would have to be serious and mutually beneficial .
send me a pm if interested.

A different post processor apparently fixed the issue. Thanks for the help.

I am getting over a cold. I'll be trying the machine today again and report back.
Thanks for the help so far.

As I stated, I did not look or touch the code in the M6Start or M6end. Am I supposed to make changes to the default settings that Mach3 install comes with?

General Mach Discussion / machine goes to wrong coordinates after Mach 3 tool change script

« on: November 23, 2016, 10:06:54 AM »

Perhaps someone can look at a snippet of code and tell me if it explains why Mach3 goes crazy after it stops for a (manual) tool change). Mach 3 is configured as "stop spindle, wait for cycle start". 
When I first  start the job, the tool change light  flashes and waits for a second "cycle" press. I press, and the machine starts to work normally.
When it reaches the end of the code, it stops and asks for tool change( T2). After changing the tool, when I press cycle, instead of going to the correct coordinates to start cutting, the machine runs away until it hits the safety switch at the end of the axis.

At this point, in order to continue, I need to send it zero, and do " a run from here" operation. In this case, the machine works normally.

I am stumbled. The only change I've made is that I have a new PC and installed a new version of Mach3. The first pc would always crash if I used the "stop spindle, wait for cycle start" option. So I always ran it with the "ignore tool change" option. I never liked this option, since I would, from time to time, forget to change the tool number in Mach3.

The mach3 script is unchanged, and I imported the Mach 3 configuration from the old pc.

I'd like someone to look at the code and perhaps shed some light on the issue.
thanks
tony

General Mach Discussion / Why does Mach 3 sometimes scroll through code slowly?

« on: October 19, 2015, 08:10:19 AM »

Sometimes, when I do " a run from here" task, Mach 3 moves through each line of code very slowly. At times, though, it moves fast. What's the secret?

General Mach Discussion / tool diameter did not change

« on: September 21, 2015, 08:10:15 PM »

Very strange.  I was using two tools, a 1/8 and a 3/16 end mill.  I began to drill with the 1/8 mill. When Mach 3 stopped to change the tool, I changed the tool to the 3/16, but forgot to change the tool number in Mach 3. After a few minutes of running and making pockets, I realized what I had done and stopped the machine. This time I set Mach 3 to the 3/16" tool and began to cut the pocket from the start. To my surprise, the profile was the same, that is, the 3/16 tool pretty much followed the same profile as the 1/8" tool.
There was no difference in the cut. How does one explain it?
