General Mach Discussion / Lathe wizard taper locks up crashes Mach4 Lathe

« on: November 11, 2022, 06:54:39 PM »

Hello,

Attempting to cut a morse taper today, I used the turn cycle to prepare the blank, and then tried to use the taper cycle to cut the taper.

The taper cycle has locked up my Mach4 screen, and the wizard is locked up to the point I can't even close it with the task manager. The wizard screen shows taper cycle 0, which I can't remove, and only the 'settings' button brings up the settings screen (gear icon in upper left).
This has happened twice today. I had to do a full restart the first time.

I can minimize the wizard window, and there are no hidden popups underneath the main screen or the wizard.

I reloaded the current Mach4 system earlier, but the wizard locked up again.

Any suggestions?

Jogging again moves Z by .001

Every other jogging move results in no actual movement.

A couple more diagnostic logs with the intermediate lines removed:

...
EX_JOG_INCR, 0, 0, 16, 0, 0, 0, 0, 0
EX_STOP_REQ, 0, 0, 32, 0, 0, 0, 0, 0
------ lines removed
EX_NONE , 0, 0, 16, 0, 0, 0, 0, 0
...
EX_JOG_INCR, 0, 0, 16, 0, 0, 0, 0, 0
------ lines removed
EX_STOP_REQ, 0, 0, 32, 0, 0, 0, 0, 0
EX_NONE , 0, 0, 32, 0, 0, 0, 0, 0
...

Also, setting jog increment to 0.100 inch and jogging Z+ should output 1600 pulses, but outputs only 1599. Then jogging Z- by 0.1 outputs 1600 pulses in reverse direction, so it does not return to zero. Every time jogging Z+ and then Z- leaves the position farther off from zero, so a cumulative error is introduced.

BTW, what does EX_NONE indicate

Mach4 General Discussion / Mach4/Uc100 problem with jogging

« on: May 09, 2018, 08:59:53 AM »

My setup is Win10 HP Laptop, Mach4 Hobby, UC100, Vista Pendant,Sherline Lathe, Sherline Nexgen Mill

System does not jog correctly when backlash setting is non-zero in Mach. This affects all axis.

Backlash adjustment is applied after each jog even though direction has not changed. Sometimes, the stepper goes the wrong direction, and often the jog amount is wrong. For instance a .01 jog may go .01, or may go something less. This happens whether the jog was done from the pc jog button, or the pendant, so I believe the pendant is not the problem.

Smaller jog increments result in more erratic behavior, especially when the jog amount is less than the backlash setting (which in my case is set to .003".

When making successive jogs of .001, the movement is often .001, 0, .002, 0, .002, etc.
When stepping by multiple gcodes, like g0 z .001, g0 z .002, g0 z .003 ..... the system seems to work correctly as shown by test indicator and visual observation.

UC100 is set to 25khz, but testing with 100khz had the same result.

Backlash should only be applied when changing directions.

System works correctly when driven by LinuxCNC so problem is not stepper malfunctions or the Sherline motor drivers.

Any ideas?
