Downloads locking up could be caused from several avenues. The "behind the scenes" settings and plug-ins in FF can cause problems. Firewall settings/permissions and other Internet Security settings can cause it.

With all the security needed to safely surf the web any more, it becomes tough to determine exactly which hole the rabbit went down!

General Mach Discussion / Re: ok to toggle single step on and off while turning??

« on: January 17, 2012, 10:55:05 PM »

I toggle the single step when testing a new program and have had no problems.
Also, once "stepped through" I do a dry run for one more test before introducing coolant and stock.

Those are the files from my brother's lathe.

I fully understand your position, Hood!

OK, I hope the files are in this .zip file! (If the forum will let me attach it)

Well, Hood it appears your suspicion of the spindle not being up to speed was correct, at least on my lathe. I added a g04 right after the t1717 line to allow the spindle time to accelerate to stated RPM and the feed rate was correct. I then reduced the accel time by 1 second in the VFD, increased the accel delay time .5 second on the Spindle tab of Ports and Pins, and removed the g04 from the program - all is good! Now I have to get the braking resistor installed on the VFD to get the spindle decel time down and I think this one will be optimized!

I'll try to attached the files from my brother's lathe if you want to look at them. We will try the same tests next time I'm there.

Thanks for all the help so far everyone!

Thanks, Hood!
I'll give the G04 a try this evening and let you know.

FYI - The lathe is set up in a gang tool method with interchangeable tool blocks holding 5 tools each. Tools 1 and 2 are constants and have their own permanent positions on each end of the cross slide. Axis A is the parting blade and is on an independent slide. M08 activates the motor for tool 2 which is a side drill and M07 activates an air cylinder that carries the part extraction chute.

Hi All!
I'll be going to my brother's to get that info Tuesday evening.

In the meantime, I discovered my lathe pulling the same trick! Attached is the program and the .xml from my lathe.

Everything performs great until it gets to tool t1717. When the g01 line is read the feed rate DRO starts at .012 and quickly drops back to .007.
When t0101 is called next and the g01 line is read, the feed rate DRO reflects the .003 rate. The spindle RPM remains stable throughout the program and performs as directed.

I had m06 in front of the tool change lines and took them out trying to determine if that was the culprit - but NO, that wasn't it.

This one has me scratching my head!!!!!!!!! Any ideas or thoughts?

It may be a couple days before I can get back to this lathe as it is 35 miles away and was just there last evening.

The Mach version we are using is R3.043.022 - same as on my new lathe.

For clarification, after the M06 line the tools are manually indexed on the cross slide with the exception of the cut off as it is mounted on the rear post. The program references the front post all the way through and we use a big offset with negative X values to perform the T0303 cut off operation (same as had been done in my programs).

The spindle RPM remains constant with the exception of turning off and on for the tool change. This was being done as a safety issue to eliminate the chance of inadvertently having a tool contact the rotating spindle during tool change.

This is all relatively new to my oldest brother and thankfully he is using these issues as a learning tool to become accustom to the lathe, the program, and the controls. He runs a range of materials - from plastic to 416 Stainless on this lathe whereas I only ran aluminum and brass. Before he purchased the lathe we set it up to cut and thread a 1" NPT fitting and it worked great.

The replies and help are much appreciated!

It's been 5 days since I posted this with 30+ views but no responses. I guess the problem either stumped everybody, I somehow made everyone upset, or the solution is obvious and I'm an idiot.
