ty ty i totally missed that, says right there "go to safeZ when stop button is hit"... it was at 0

General Mach Discussion / Retract Z on feed hold or stop

« on: June 29, 2023, 06:36:04 PM »

When I use 'feed hold', 'stop' or 'reset', the machining stops right where it is and turns off the spindle... this is all good except I would like it to also retract the spindle height to a safe distance from the part... maybe 2in/50mm
I cannot find any setting to do this and if there is a problem such as needing to tighten stock clamps or even just cleaning away chips or lubing the bit, it really should immediately retract.... only exception would be E-stop, which is working fine.
Is there an option to cause a Z-Axis retraction on 'feed hold' or 'stop' in Mach3?

Also, I do have 2 of these cards, both do the same identical thing

Thing is though, the MPG only has trouble in certain mach3 modes.
It clearly shows each and every pulse being registered on the mach3 diagnostics tab, it has to be the mach3 settings

General Mach Discussion / MPG movement erratic

I'm having trouble with the CNC movement using my new MPG.

I recently connected the mpg (seen in first pic)
To this controller (second pic)
Wiring (as seen in 3rd pic)
I used the settings seen in "MPG Mach3 Settings.txt" attached

It works for the most part....
When I hit TAB and switch to MPG:
In Velocity mode, I get good smooth movement when the MPG multiplier is set to X1...
But when I switch to X10 or X100, (I have to hold down the side button on the MPG), the movement is so horrifically brutal, its like the acceleration/velocity in the motor tuning is completely ignored and sounds like a hammer is hitting the gantry (as if its trying to move way beyond the motor speed limits).
How do I fix this?

When I switch mode to Step:
X10 and X100 work perfectly, but it will not let me select X1... I have to click on 'cycle jog step' manually to get to X1

I have set 'jog increments in cycle mode' in 'general config' to 1/10/100 for the first three.
Ideally what I would like is for the MPG velocity mode to have the options of 1/10/100 to move things out of the way quickly when a job is finished....
And when setting up a job, using the MPG in step mode, X1 = 0.01, X10 = 0.1, X100 = 1.0

Also under general config, might wanna try:
remove tool offset
distance mode and IJ mode, swap what they are and try again

I finally found it!
Its in General Config -> IJ Mode
Needs to = Incremental

Solved!
Thanks guys!

ok so it appears to be a problem with Mach3 settings.
I reloaded Mach3 and poof, the gcode appears perfectly in the display window.
But then if I load the modified XML file that came with the BOB card... that one circle is gigantic.
So it definitely has to be a setting in Mach3

its this line in Gcode thats being misinterpreted: G2 X74.3 Y34.353 I-26.675 J9.747
Its supposed to be a circle 50.8mm in diameter, cut with a 6mm endmill... but it looks like it wants to cut a 500mm circle

Both XML files and the Gcode are attached.
I designed it in MM, and Mach3 is set to MM.
