but your new drive will drive 4" if youd do G91 Z-4 f10 for example in MDI Input

TPS - thank you for an explanation about Mach 3 and how it works precisely.

Enable inputs are used to switch on and off the laser work, so they are kind of emergency signals, they are not as FAST as PWM input.
For example, they can be connected to a general signal connected with "I will soon use a laser" or "Laser is safe to use now" but these inputs are not direct modulation inputs.

I asked Allan to use Program 0 so this way Enable inputs states are not taken under the consideration.

Could you confirm that you would like to use two independent inputs, one to set the power level with a constant signal and second to switch it on and of?
It is possible but probably this will work well with ANalog input and one of the Enables input.

Instead of using M10 and M11 maybe we can just use the M3 S0-255 command to switch on the laser and M3 S0 to switch it off?
This way using one signal without any of the Enable inputs.

so that actually means, only the external board solution would work, what still not explains why we were not
able to get the enable Input working at all.

even if you think it is good to set power at the Programm begin, only the fact that Me allways produces a small
delay will create a burn mark at start and M5 at the end.

this might be good enough for laser cutting, but not for engraving.

if you use M3 Sxyz for power control during g-code this will break constant movement,
that would meam, every time in g-code where M3 Sxyz is used X/Y will stop (and create a burn mark).

M10/M11 will not break constant moves.

all the others witch use Mach3 for laser do it the same way (M10/M11) it is not depended to your (CP0-10V)
board. if you do a serch for M3 and laser you will find a lot threads, witch are describing allways the same
Basic Problem.

Hello Mateusz,
Mach3 is i Little bit different from what you kown it t assume.

in Mach3 (for laser application) it is normaly handled this way:
M3 S********* -> set the power for laser usage
M11P1    -> followed by a G-command (normaly next line) will turn ON Output1 (on Controller) synchronized
                  to  start of axis movemend
M10P1    -> does the same Thing but only to turn OFF Output1

for this reason i advised A11an to set Laser in Mode 2 what IMHO should turn ON laser by Enable Input 1
goes high.
then we made a M3 S1000 to put some voltage to terminal 6 for power and the we put 5V (measured 4.9V)
to terminal 3. measurement was done  between terminal 3 and 4.
but by putting this 5v to terminal 3 Laser did not Switch on beam, and that is the main Problem.

When I run some gcode I get 4.95v between pin 3 & 4 with it wired pin 8 10k resistor from 5v to pin 8 on bob
that's like it should be M11P1 is switching Output and Output gives the 5v to Enable Input 1.
so Mach3 and Output are OK, but laser is not turning ON.
the General Problem stay's, and it is, that the laser Controller is not switching ON by using the enable 1 Input, so you can push on the supplier from laser, because this function is not working like described in Manual, or give the
external circuit a try.
this are the only two possibilities i see for the Moment, but maybe i am wrong.

you have to choose TTL(H) variant.

you are right, sorry to Point you to the wrong circuit.

the plan is to use the PWM Input of your Laser control

I control the spindle speed through mach3?
yes, but you control it by using the 0-10V Signal, or am i wrong?
