Mach SDK plugin questions and answers. / Re: trajectory buffer - missing vectors after STOP and START

Thanks. In this case, further work on external pulse generator does not make sense. Using the parallel port is much more convinient.

It look's like you are right. Issues with trajectory buffers are gone when i'm using feedhold.

Hovewer, in lpt mode i always used stop (or even emergency stop) and never experienced any problems. It was
very convinient. Is there any way to continue (automatically) correct path after stop or estop ?

Mach SDK plugin questions and answers. / trajectory buffer - missing vectors after STOP and START

« on: August 02, 2015, 01:36:01 PM »

Hi. Sorry for my poor english (i'm trying to do my best).

I'm working on USB motion controller. I noticed that after stopping program (Stop button) and starting it again (Cycle Start) some trajectory
vectors are lost. For example:

G2 X5 Y5 I5 J0
G1 Z6 F200
G3 X0 Y5 I0 J6
G1 X0 Y0 Z5 F1200

If i run program and then stop it almost immediately, mach stops filling trajectory buffer (GMoves Movements[0x1000]) after (for example)
70% of first arc. When i start it again it doesn't continue to generate first arc but go
straight to second or even third line of gcode.

I also noticed that it's probably correlated to "MainPlanner->ExBufferHi" value. The higher value it is, the more vectors are lost.

Could someone help me ? Thanks in advance.

Hi. Sorry for my english !

I'm working on simple mach 3 console. I'm going to use one of existing projects (atmega8 usb joypad - 4 analog
axes and buttons 1 to 12)

I need limited functionality:

- jogging (3 analog axes)
- start, stop (= emergency stop), tool height probe, goto 0, goto home, rewind g-code

Starting each of the functions (except of stop/e-stop) will require pressing common "safety button".

Is it possible to configure joypad plugin 2.0 to do this ?

Ok. There is something wrong with button. I managed to enable analog mode.

I have a JoyPad (Chinese) where the POV (four left buttons) and the left joystick are switched when the "mode" button is pressed. A LED indicates the selected mode.
Maybe it is the same for your game pad.

Pushing MODE button has no effect at all. LED is always off, i don't see any change in joystick behaviour. I suspect that this is fake led and button.

Hi. Sorry for my poor english.

Is there any way to configure standard digital buttons on my joypad as z-axis jogging buttons ? My joypad has 2 digital joysticks but second one in visible in OS as 4 simple buttons. These buttons are configurable but i have no idea how to control jogging with this.

Thanks
