General Mach Discussion / Re: My stepcraft DL445 laser leaves a path
« on: June 12, 2019, 08:31:33 AM »
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 ?

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.

Chank Hervella,

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

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.

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

Hi pcrego,

Do you have a Mach3 license registered in your own name or the name of your company ?

Mach4 General Discussion / Re: NOOB Alert (MACH4 & 57CNC Issues)
« on: June 10, 2019, 02:37:42 AM »
Just an observation from your video...

You are using USB connection between your PC and the 57CNC and you also appear to have a couple of USB memory sticks connected to the PC.
It depends on exactly how the PC polls it's USB hub or hubs but leaving memory sticks in the PC when running Mach3 and using a USB connection to the motion controller can be very bad news indeed - I have not tried it but maybe Mach4 is similar ?

I think you should remove the memory sticks and change your PC to 57CNC connection to Ethernet (which is far superior to rejection of electrical noise issues etc.) and see if this resolves the problems.
