I just built my laser from scratch. I’m running Nema 17 steppers, which move fine.
I have some issues, however more on that in a min.
Hardware: all brand new.
-50watt CO2 laser from cloudray.com
-nema17 steppers from NOS I had from a printer build.
-MCWLaser CL-MYJG black model, 50w PSU
-TB6600 stand alone stepper drivers
-Meanwell 24v PSU for steppers and RDC.
Issues: X&Y axis both move fine, however I cant seem to find where to adjust the setting for max X&Y travel length, nor can I find how to set the correct steps per mm. The motors are standard 1.8degree -Nema17’s, with the drivers set to 1/32 microsteps. The belt is a regular GT2 timing belt, with 20tooth gears. So I need to set the steps per MM to 160 according the the prusaprinters.org stepper calc.
I also don’t get ANY response from the controller when an end stop switch is triggered. The motors just keep going. Only thing that happens is one of the many LED’s in the row of 15 on the RDC will light up. But that’s it…
Next issue is… With the RDC connected, I can’t test fire or even just “fire” fire the laser. If I disconnect the controller from the power supply and leave only the laser connected to the power supply and press the test fire button on the PSU itself the laser will fire. So I know the laser and the power supply are good. I have connected the door switch screw terminal (on the controller) directly to ground as I have no door. Same as the 2 water sensor positions. Both are hard wired to the closest ground location on the screw terminal block. The system is water cooled, but I don’t have a sensor…
RDC onboard diagnostics do not show a highlighted box at either water sensor or the door protection switch, but does show activity when an end stop switch is triggered. However as I already stated, when triggering an end stop switch the motors continue to run.
Can somebody please please please please please help me figure this thing out. according to the manual I found online there is also supposed to be a “Vendor” option inside the RDC menu, which isn’t there. The version is 15.01.19
Also, just to add additional information, at any given time the LED light status is show the following.
1-8 = off
9 = on
10-13 = off
14 = blinking
15 = on
If someone has the information could you also please post what each one of these lights stand for, as I was unable to locate that information in the manual…
Thanks for your time…
