General Mach Discussion / Re: Z speed limiting xy speed

btw in your Video i have recognized that you are working on a laser Project.

here:

http://www.machsupport.com/forum/index.php/topic,12444.0.html

Tweakie has documented his hard laser road.

as far i got the Information out of this thread the "clue" is to regulate XY Speed instead of laser power.

'hopefully' Tweakie is jumping in here, because i think he has the Experience on laser.

ok let's do some basic's


F100
G1 X100 -> will Need 1 Minute because distance is 100mm

F100
G1 Y100 -> will Need 1 Minute because distance is 100mm

F100
G1 X100 Y100 -> will Need about 1 Minute 24 seconds because distance is about 141mm (SQR(X²+Y²))

i hope this example makes clear, that every Z axis movement will slow down XY, because
the real distance is allways longer, than a simple XY movement, because machine is allways
doing constant Speed based on real distance (in CV mode).

@TPS
  This does not happen with with X and Y if I make Z constand and change a value  in X or Y.

can you please explain a Little bit, sorry my english is not good enough.

have you tryed "real" (x3) instead of "huge" values?

Hi,
steps per mm and Speed is one thing,
acceleration is an other Point.

i don't know the dimensions of your machine, but i would start with some test's
by entering command into mdi.

for example:

F500
G1 X500 -> measure the needed time

 F500
G1 Y500 -> measure the needed time

F500
G1 X500 Y500 -> measure the needed time

just to make sure not one of the 'major' axis are making the Limit.

then

F500
G1 X500 Y500 Z5 -> measure the needed time

to get a 'feeling' what is 'pushing' the brake.

what i don't understand:

if
-e-stop is ok
-jog mode is on
-cslab is comunicating with mach

axis dro's should Change if you jog, even if Motor Drivers does nothing.

maybe someone else has got an idea.

i mean this Jog on.

sorry asking this, but i am wondering that you don't see axis dro changing.

Mach 3. Yes jog is turned on. I hit the tab button. Mpg is selecting the correct axis and cycling through the increment selection as it should. Thanks for the input though.

and if you use the Keyboard arrow key's?

Its my understanding that the ENable pins do not have to be wired, but I could be wrong.

if i have a look to Manual of 4042 drive the enable is required.
