Title: My stepcraft DL445 laser leaves a path
Post by: Chank Hervella on June 11, 2019, 08:06:08 PM
Hi everybody! My laser works fine but when is running leaves a path, I use Aspire 9 and Mach3, does anyone have a modified post processor with M10 and M11 commands? I'm desperate because I can not find a way to make it works, thanks for your help

Google is your friend. Searching for "vectric laser post processor" gives as a first hit:

There are Vectric Post Processors for Mach3 and Mach4 Laser use in the Downloads section here;  https://www.machsupport.com/forum/index.php?board=8.0

I tried with this post processor but the same thing is happened, I saw the different way to switch B axis for Z movements, maybe this works!

From your pic. you have 2 distinctly different issues...

1) The 'dot' burn at the start and end of each toolpath - this can be fixed by using the M11/M10 commands.
2) The streak lines which indicate that the laser is not turning off properly - this can be fixed by using a 'pull-up' or 'pull-down' resistor (depending if your laser uses TTL(L) or TTL(H) switching) connected to the switching signal line for the laser.

Chank Hervella,

Do you have a diagram of how your laser is connected to your PC and can you also post your .xml file.

i dont have a diagram, but here i leave you my .xml file and machine specifications files, my machine is a stepcraft 840 and laser (DL445) is a complement for the same machine brand. i aprecciate your help Tweakie

Hi Chank Hervella,

After studying your .xml and all the documents I have to backtrack on my earlier posting…

As far as I am aware (last time I looked) the UC100 Mach3 plugin does not support the Mach3 M11/M10 command set and if that is still the case then it rules out using the Vectric Laser Post Processor as a resolution to the excess laser burn at the start and end of the toolpaths. (As you said earlier, you tried it and it did not work).

As for the laser streaking – because your DL445 is totally interfaced with the 840 controller rather than your PC it would perhaps be unwise to make any electrical modifications without the approval or endorsement of Stepcraft / Stoneycnc. So, I think you need to be talking directly to Stepcraft about the streaking issue and get their suggestions on the way forward here.

Thanks Tweakie, Stepcraft has the worst technical service, do you think my laser needs a modification you said before, Pull up or pull down resistor?

The Laser manual is not clear if the ON/OFF signal is active High or active Low.

Assuming the laser is connected by the 15 pin D-Sub connector then, using a voltmeter measure the voltage on Pin 13 (with respect to GND Pin 10).  Is it High (5Volt) when the laser is ON and Low (0Volts) when the laser is OFF ?

What a mess haha 😂 I think is better if I buy it  a old computer with LPT port, right? What do you think?

Sad to say but yes, I think that would be the easiest solution.

had a quick look to the UC100 manual Appendix A. : New functions and bug fixes:
it should Support M10/M11.

but don't know wether it is working
Title: Re: My stepcraft DL445 laser leaves a path
Post by: Chank Hervella on June 13, 2019, 12:17:08 PM
Yes, I saw this but I think is only compatible with UCCNC because in Mach3 doesn't works 😭

never used it, but M10P1 means Switch Output 1 ON, and to what (ports&pins) is your Output#1 assigned.

for the Moment you use M3/M5 to turn laser ON/OFF?

what is your output configuration Config -> Ports&Pins -> Spindle Setup -> Relay Control ?

are you using are original UC100 or a chinese clone?

I use M10 and M11 with original UC100 cable, I posted my configuration files before

sorry missed that you posted your Profile.

you are Controlling your laser via Spindle Motor control step Signal (chankspindle/chankspindleoutput).

output1 is assigned to pin0 (chankoutputs), so M10P1/M11P1 can not work (should be pin17)

Could you modified my profile file please and re-send me then I'll try it, Thanks for your help

Post by: TPS on June 13, 2019, 02:03:59 PM
well, walked through the stepcraft Manual, not getting 100% clever, but here a "try"

pls try also Output1 Active Low Setting.
Title: Re: My stepcraft DL445 laser leaves a path
Post by: Chank Hervella on June 13, 2019, 04:04:34 PM
Same thing my friend, I tried with active low off in output1 after I tried on and nothing new happened, thanks for your time
Title: Re: My stepcraft DL445 laser leaves a path

i will try to contact stepcraft to get more information

thanks, i tried a couple times and they said "we dont have technical service support to mach3"

next try.

got some more documentation about Pins of laser Interface.

and sorry, i was wrong in an earlier reply M11P1 means Switch Output 1 ON
Title: Re: My stepcraft DL445 laser leaves a path
Post by: Chank Hervella on June 14, 2019, 11:50:43 AM
i tried with the last file, laser never on, i activate low in output 1 and the laser never off, i bought a UCCNC  ;D

now i need to configurate

OK, one eye is a Little bit sad to hear, that you gave up, but only one eye. ;) ;)

Everything is perfect with UCCNC, my machine was created to use with this software, that the reason doesn't works perfectly witc Mach3, thanks to all the people who helped me, this is the best Mach3 blog ever!

I am pleased to hear that you now have your machine working as it should - your latest engraving picture looks excellent, good fortune with your future laser adventures.
