The GREEN MACHINE

Here it is. Both connector styles are installed.

I am using the LO DSP controller.
In the schematic I couldn't find how to wire potentiometer and manual trigger button.
Would these functions be provided by DSP controller, so no need for pot. and man. trigger?

this is the schematic I am using:

The controller has both those functions on the DSP local panel. You can easily wire a manual fire to the unused Level High/Low that does not go to the DSP. Thee pot is not easy to attach. You would need a way to bypass the DSP signal via a SPDT type switch.

It is not worth the effort in my opinion.

Thanks Bart,

If Level High goes to DSP can I use Level Low and Gnd. for Manual trigger?
I prefer to ask maybe stupid questions than get the magic smoke out...

[bdring]

Yes,

That is correct.

I have installed DSP controller and all other electronics.
Laser is working, but I have to make SKINS, Air assist and fumes extractor.

Here is how I have mounted the LCD panel.

Awesome build That curved extrusion looks good, I might have to have some myself!

I have just started the electronics side of my build, and I happen to notice you have the same set up as me. LO DSP with Laser Interface Board as drivers.

I have built my board up from Mouser components, I left out some components I didn't need. (But used the schematic to make sure I didn't forget anything important (I traced all the paths on the board etc) I then started to connect everything up; dir and pul, to the associated pins on the board, step and direction. I then fired everything up, after a little tweaking in LaserCAD and 2 blown drivers (that was a hard lesson learnt!) I got a stepper to move. However there was a slight problem, it would only move in one direction. I tried everything but to no avail. The LaserCAD settings are a bit baffling and I couldn't find much info on the support forum.

So, I was wondering if you have managed to get yours to work. And if so, how? Also, would you please be able to share your LaserCAD settings and wiring set up?

I know its a big ask, but I would be really grateful as I am just about tearing my hair out trying to figure the problem

Many Thanks

Hi Buz,

So, I was wondering if you have managed to get yours to work. And if so, how?

I have the 4 axis POLOLU driver from Bart (not the Laser POLOLU driver)
I have used this schematic:
http://www.buildlog.net/documents/D32018_rev_1.pdf

Also, would you please be able to share your LaserCAD settings and wiring set up?

I can take some screenshots with my settings, however, the best thing you can do is to start a new topic asking for support either on this forum or on Light Object support forum if the question is more specific about LO DSP.

I have calculated the values for all the axis and modified the Distance (um/pulse) in the parameters.
X=5.715 microns/step
Y=6.350 microns/step

However, regardless of the value I have for the Z it will move the table 10mm and the display shows 17mm, when I move to 20mm display shows 34mm

Anyone have experienced this?
