General Mach Discussion / Re: Need Help... Laser cutter running on mach3

« on: October 06, 2021, 11:50:59 AM »

Hi all, after weeks of trial and error I manage to get the CNC working. After exhausting all the tests I could come out with, in one last desperate attempt I decided to change the Mach3 with Arduino (which I'm a little more experienced with), after all the wiring and troubleshooting the machine worked perfectly. Nonetheless I was not able to accurately pinpoint the malfunction. I hope this helps someone.
Thanks to all and specially to Tweakie.

Hi Tweakie, thank you for replying so quickly.
I've already tried reducing the acceleration and velocity in previous  attempts, but to be sure I adjusted the parameters to the indicated ones, and somehow, I got worst results (picture bellow)…
Some piece of information I forgot to mention, the misalignment always happens towards the positive axes, in not a single test it has happened in the negative axes.
Thank you all for reading an comenting.

I built a CNC Laser cutter a few years ago, it has been running fine until a few days ago.
First the X Axis failed and when I tried to cut something it just draw a line parallel to the Y Axis.
I replaced the motor controller and it worked just fine. A few days passed and it started to have some issues in the X Axis, this time there is some misalignment in complex cuts, I run some tests and the problem amplifies the more the axes are moved. I've tried every idea I had for the last week or so, like verifying every connection, replacing the motor, replacing the mach3 controller, I even reconstructed the axis in hope it was some mechanical issue and now it happens in both axes. I've run out of ideas.
Attached is a photo of the problem, I cut the rectangle then move both axis and rerun the gcode, but the cut is misaligned from the original.
If any of you guys have had the same issue or have some idea of what might be causing the problem, I would be extremely grateful if you share it with me.

Hi Tweaky,
Thank you very much for your reply  , I'm going to try this as soon as possible and I'm going to let you all know if I manage to get it working.

This is the board I need to wire the PSU to.

Spanish / Mach 3 controller connection to laser PSU to use with M10/M11 commands.

Hi everyone, I'm new to this forum please be patient with me .

I'm having problems with the connection from the Mach 3 controller (with parallel port and USB, which can be seen in the attachments), to the laser PSU to use with M10/M11 commands in mach 3. I can´t figure out how to do the wiring correctly. The laser is correctly connected to the PSU as when I press the Test button I can see it trigger. The only info I could find are the attachments seen below and from that I can´t get it to work since I'm new to this subject. Could someone please explain to me how to do the wiring correctly??.
