Can you post a section of code that shows the problem?

Is there some reason you came HERE to rant about your machine AND lack of understanding of building a CNC machine ?

I am with Hood on this one GOOD LUCK getting help here.

OK Mach does not allow reverse while in G91 mode(inc)

Also the run from here and set next line do not seem to like it either.

Just a thought, (;-) TP

To speed up the feedhold/pause reduce the number of lines in the look ahead setting (gen Config) down to 2 will just a bout stop on demand BUT it may reduce the smoothness of mach with short line segments.

Normally to restart I use  Set Next Line . Normally with flame cutting there is no fancy offsetting involved so run from here does not gain you anything.

Runs ok here.    Try turning OFF all the A rotational stuff in Gen config. Rollover,shortest path etc.

Most Cams such as MC treat the a axis as it only has 360 deg rotations so it does not use rollover etc,

Just a thought, (;-) TP

When you use Radius correction Mach takes the workpiece diameter and uses that to set a blended feedrate of the A (up to as fast as it can move). You would normally see this with 3D work where all the axis could be moving at the same time. Being that the A normally moves in Deg per min this will speed up the work up to the A  max Vel as set in config.

Without this a move of  X1.000 A40 F20  would be painfully slow as the feedrate is set for both axis at 40.  the slowest moving axis would be A at 40 deg per min (SLOW) and the X could not run any faster as it is linked to the A move as far as feedrate.

This feedrate for A (1357 DPM) is not very fast. it is only about 3 rpm which converts to about 11 ipm surface speed. About right as far as feeds and speeds are concerned.

Reset them all then do a save file.

The MC sounds like  a post problem it is not setting the proper speed based on the tool# info

(;-) TP

HUM tested here and I don't see any problem. The A feedrate is only about 11 ipm at the surface.

The feeds are also switching back and forth between feed and rapid.

Are you gaining in the z or loosing in the z?   

Is this a new machine ? Has this code ran on another machine ok?

Just some thoughts, (;-) TP

Look in Config, System hotkeys.  AND reset the hotkey value for the X- jog.

Most Cams set the spindle speed based on tool selection. Check your MC tool # for proper setup as to spindle speed.

Just a thought, BUT do you have the A axis set to use radius for feedrate??

Config,toolpath, check box
Settings page, A radius = xx.xx

I recall there was a bug at one time that allowed the Z feedrate to be effected by the A feedrate when synced to radius.

What is the gear ratio of your fouth axis?

Just a thought, (;-) TP
