DSP controller. --System settings-- (LaserCAD v5.77)

[Yepez]

Hello
Where can I find documentation, Information or description about the "Manufacturer Parameters" & "User parameters" ?

Principally the ones marked, I just want to know how this parameters affect the behavior of the movement in the machine, because the movements seems very shaky, but if I use my system without the DSP and connect it to Mach3 with the Parallel port the system behaves very smooth.

So, I think this parameters are involved, and I have to tune it up, but I have no information about it.

Please I need some advice about it.

Hi
I dont know what system you have, but for the first I have a K40 chinese system converted to DSP and attached are the settings on this.
first you should change the tube settings to "low level"
then you should cut a square of 40x40 mm and then make the settings in the manufacturer settings click the " ..." botton to the right of X-axis pulse settings and put by expected the mm what you have sett at the cutting and on the next line "actual put the measurment from the cut in the same with the Y axis pulse setting. this adjust the driver for the stepper.
then set the pulse edge and datum.
set the laser tube power not higher as 85% to avoid overloading the tube. the real laser power is then allways a procentage of the 85% what means if you adjust the power settings on your work to 10% this makes the actual power out put to 8.5% ( 10% from 85% = 8.5%)
this should give you a good first working.
if you got morequestions just send a PM to me this way I could send you some picture my PM adresse is " a542002@hotmail.com"

That's not how the max power works on a 2012 DSP. When you set max power to 85% it's capped at 85% it does not apply that to your input on a job(EX: 10% = 10%, 85%=85% and 100% = 85%). I have requested they change it to the way you say it works, but that's not how it works today.

Directly out of the LaserCad manual:
Space speed: the max speed of the machine when there’s no laser in the work process.
Space Acc: the accelerated speed of the machine when there’s no laser in the work process.
Start speed: the initial velocity of the machine.
Min_Acc: the min accelerated speed of the machine in work process
Cut_Acc: the max accelerated speed of the machine in work process
Engrave_Acc: the max accelerated speed the machine while engraving. normally this should be
larger than 8000

Speed_Factor and the *_Jerk settings are not explained.

Datum defines which direction is the home direction on that axis (aka which direction the controller will move the steppers in order to find the home limit switch).

[Gadroc]

Also I believe all of those settings (minus the start speed) are defined in millimeter per second per second. Marco would have to confirm that.

Here are my current settings for the user parameters which are working very well for me. Obviously depending on your machines mechanical parts you might have to increase or decrease these settings.

What kind of machine are you working on?

Hi
did you check this with a ampmeter???
I did it and its still the old one I have the newest lasercut 5.77

Yep.

I have a meter always on. 32% = 15ma on my machine. I have set max to 32% in the settings panel and when I cut at 32% in a job that results in 32% on the machine and 15ma. When cutting 1/16th acrylic I use 13% which results in about 7-8ma (at work and don't have my notes sheet with me) which is 1/3rd power (13% = 1/3 of 32%) not 13% power.
