Feature Requests / Re: List tool change line numbers

YOu could set up Mach3 to do that . I think it has already been done a while back. You set up the M6 macros to WRITE to a history file. The data would include the filename line number and tool number. It would record programs WHEN you wanted to run a BIG ONE by using a LED to indicate when  you wanted it to run OR just bypass the operation.

Just run verify at the end of the program It rehomes and telll you the error from the last refhome.

Reduce the accelleration on xy as well. Sounds like you are loosing steps on them as well.

What version of Mach are you running. I just tested some Gcode in V.049 and there are problems with ABS(G90) Gcode on the A axis.

Quite a find you have there Tweaky. I bet the aviation buffs are drooling big time over that one.

The 400hz power is very common for aviation and marine and military. It has a VERY high power density small motors can create large forces. Ac motors can rev very high at 400 hz. At 60hz you are limited to 3600 revs and 400hz it is like 24,000revs.

IF you can make more than a 360 deg move then there is no hard limit on A. It would not make any sense to have one. The theoreticle limit is like a zillion  revs in each direction. WAY UP THERE.  So I dought you have hit it.

One thing to remember when working with the A axis is SOMETIME you are going to have to unwind all the degrees you called for. Either by runing the code or refhome the axis to reset the machine A0.

In the old days you only had 0-360 degrees in a rotation and you had to account for that in code. Today you have it better with Mach3 letting you wind up the axis.

HOW do you have Mach setup for on the A is it 360deg or continous roll over?

Set up your machine then do a test. Refhome the A axis so the machine dro vlaue is Zero and then zero the work dro. Now the A is at machine home and work home.

Now from the MDI try a Gcode like G00 A 3600

The A should rapid around 10 times in the positive direction.

BUT even then if you are doing carving on a tube you should never go beyond 360 anyway(;-) (oldschool)

I think yo have something going on in your MachinePC that is causing MACH3 to stall or hang up from time to time.

Easy enought to test post a copy of the Cut file and we can test the Gcode.

Just a thought, (;-) TP

IF the servo was smoking hot and leaking grease I would replace the motor.

I use something like this to open files by file name.

Fname = InputBox("What is the New File Name","Grank Grind FILENAME", DFN)

It gives you a popup box to answer the question


THe use the variable "Fname" to open a new file

Do a search on here there should be a macro for that.
