Mach4 General Discussion / Re: PROBLEM WITH LASER START-UP POWER WITH PMW MACH4 AND POKEYS

« on: December 10, 2021, 04:27:16 AM »

I get from polabs support the latest, i don't know if i can share it here or is ok for you. I had problems with M62 too before i upgrade plugin/software, don't spend time figure it out without upgrade the versions. Ask polabs for newer or tell me to send it to you.

I opened a ticket at polabs but I want the latest versions if you want?
Thanking you, I will do the tests this weekend.
Thank you

Hi
I just tried the config.
I have mapped the output 0 on pokeys with the output OC1.
(see picture) and do the gcode with M62P1 but no activation of the OC1 output.
I looked for other solutions, put the output on an Enable or put OC2 (M62P2) but ditto, I have the latest version mach4, pokeys57cnc, plugin mach4 and firmware. I also checked the M62 / M63 option in the plugin
I also saw that there are macro files in the M162 and M163 macros folder, what are they used for?

If you have any suggestions, I'm interested
Thank you

But I don't know if I am configuring M62Px correctly.
I associated Spindle on (therefore M3) with relay 1 and spindle forward with relay OC 1.
But how and where is it declared that M3 = spindle on and where is written that M62P1 + = *********X?
Following the tests M62 / M63Px does not work with the gcode (above), M3 activates relay 1 and relay OC but M63P1 does not cut OC.

No need to use spindleOn/spindle ffw for M62P*, just set pokeys oc to an Mach4 output (ex. Output2) and use M62P2/M63P3 with follow code of G0/G1, be sure that u have the latest upgrade of pokeys software/board. There is a plugin from 10/2021 and software vs is 8.85.

Yes ok I saw for the mach4 output, I will try the config.
On the other hand on pokeys we find that the soft version:
  PoKeys v4.5.0 Configuration and PoBlocks (8.9.2021) .exe (53.41 Mb)
and PoKeys Mach4 plugin version 8.78.0.4342 + manuals.zip (7.5 Mb) with date of 09/2020
I don't see a plugin version of 10/2021.
Otherwise my softwares are ok.
I'm doing tests tonight.

Regards
Thank you

Hello again
I reread your post and understood that M3 allows M62Px to work so the gcode is ok.
S12000M03 -> power output pmw and power on laser 12v -> it's ok
G94 M63P1 F1016.0 -> power off OC
X0.000Y0.000
G00X0.033Y15.914M63P1 -> power off OC
G1X0.033Y15.914M62P1 -> power on OC
G1X13.855Y13.140M62P1
G1X8.012Y1.013

But I don't know if I am configuring M62Px correctly.
I associated Spindle on (therefore M3) with relay 1 and spindle forward with relay OC 1.
But how and where is it declared that M3 = spindle on and where is written that M62P1 + = *********X?
Following the tests M62 / M63Px does not work with the gcode (above), M3 activates relay 1 and relay OC but M63P1 does not cut OC.

I saw that some added scripts to associate M62Px with the OC relay of pokeys?
Also following the last version of mach4 I have a very strange screen.

See my photos
Thank you for your patience

Hello
Sorry for my english.
I am coming back to you because; with mach 4 and pokeys57;
I block a little with this config with laser and pokeys and M62Px

What do you associate M62P1 with? turn on spindle?

I have to manage the supply of the spindle in 12v -> I put M03, spindle operation which turns on the laser but not the diode control (normally this is done with the pmw input)
It is also necessary to manage the power in pmw> I put a pmw pokey output (terminal 18) on the pmw input of the laser

But, how do you manage and associate M62Px so the OC relay and how to wire it?
What should he control physically, if you have an example of wiring?

I understand this Gcode:
(Tweakie.CNC)
G00G21G17G90G40G49G80
G71G91.1
T1M06
S12000M03 -> power output pmw and power on laser 12v -> it's ok
G94 M63P1 F1016.0 -> power off OC
X0.000Y0.000
G00X0.033Y15.914M63P1 -> power off OC
G1X0.033Y15.914M62P1 -> power on OC
G1X13.855Y13.140M62P1
G1X8.012Y1.013

See my picture

Thanks

hi tweakie

No problem for your explain, me too.
I understand CV better and I am going to modify a gcode this evening to make a test with M62 / 63 and above all to update all mach4 and pokeys.
Great 
Thank you for your help .
I'll tell you again.

Hi

I will try to put Sxx before M62 / M63.
I would really like to vary the laser power with pmw while engraving.
Currently, the M03 command activates my laser power relay and Sxx gives it power.
example
M03 S0 here the laser is operating at 0 power
G1 F1600.0 ok
G0Z0.1000 ok
G0X0.0000Y0.0000 ok
G0X8.6869Y8.0177 ok
G1X9.5806Y7.4906F1600.0S10000 and this is where the laser create excessive and unwanted burn marks
G1X10.3921Y7.0339
G1X11.1969Y6.6265

At each line executed we see a point of impact when I go from S0 to Sxx as the laser starts fully and the movement is not yet done, but it is very fast and not easy to see it but we can see the result in the photos.

Here is my problem and the question: how to vary the laser power with pwm and M62 / M63 during machining?

And what do you mean by "breaks the CV chain"  ...CV ?

Thank for your help tweakie

Yes I understand but by controlling this output by M62Px we cannot vary the pmw power?
The output activates the laser power supply only, (OC on pokeys on / off)?
For me, I wanted to control the laser power supply by a relay so M03 and the pmw power by Sxx.
?
In the posts, I don't see that we are talking about variation with a pmw output.
Thanks

Hello forum
I am French and I have built my 4 axis CN and I am starting the laser.
I use mach4 and pokeys57cnc.
I have been a maintenance technician in industry for 22 years.
i discovered cn and i became a fan.
I also do planes with it.

happy to use cn

Mach4 General Discussion / PROBLEM WITH LASER START-UP POWER WITH PMW MACH4 AND POKEYS

Hello everyone ,
I do not know if I am in the correct discussion...

I am French (sorry ) and I have already built my cn 2000 * 1500 * 250 in size with motors with encoders and pokeys57cnc and 4 axes.
I have mach4 and it is great for me.
now i have built a machine with electric laser, with pokeys57cnc and mach4.
I use a pmw output at 20000hz just like with my spindle of my gantry milling machine.
the laser is ordered for m03 and for power S ....
but during the increase of power, for example S0 .... S10000 or S5000 or another, I have a starting point which marks and can cross the balsa support.
I tried several settings, several post processor, but I know more.
Have you ever had the problem?
Thanks for your help

For exemple my gcode:
T1
G17
G21
M03 S0
G1 F1600.0
G0Z0.1000
G0X0.0000Y0.0000
G0X8.6869Y8.0177
G1X9.5806Y7.4906F1600.0S10000
G1X10.3921Y7.0339
G1X11.1969Y6.6265
G1X12.0061Y6.2644
