Hello all,

I built a DIY/home-built 80W CO2 laser using the Further Fabrication Y1200 build guide (with the single-motor upgrade on the long axis if you're familiar with the FF design). As you're standing in front of the machine, the bed measures 1200mm left to right (the X axis as we've all been taught since grade school, but Y axis according to the build design) and 600mm deep. I have interlock switches wired to the front left corner if you're standing in front of the machine.

I am using a Ruida RDC6445G controller running version RDC-V15.01.17. I have Lightburn v0.9.24 installed on my Windows 10 PC.

For motors, I am using Cloudray Leadshine HBS57+573HBM20-1000 HBS507 NEMA 23 Hybrid Servo Closed Loop motors on the X and Y axis, and a StepperOnline NEMA 23 stepper for the Z-axis.



I have two primary issues at this time:
1) I am unable to move the laser head along the gantry with either the controller or in Lightburn. What settings should I look at to fix this?
2) Both the controller and Lightburn report the laser head position at X: 10,000mm and Y: 10,000mm. UPDATE: I pressed the reset button and this has since resolved - is it as simple as that, or is there a setting that should be adjusted to prevent this from happening again?

Neither of these problems occurred when I first hooked up the controller or before I hooked it up to my PC and Lightburn, and of course I don't have the original vendor settings. I figure both of these issues are caused by a setting that I adjusted, but I don't know which one. :oops:




Please let me know if any other information is needed and I will respond as soon as I can. Thanks in advance for helping!

UPDATE 2: Using the controller I accidentally rammed the gantry into the interlock switch for the X (long) axis and now I can't get either the X or Y axis to move. :(

Hi Cory- I am in Blaine BTW. We have recovery files which work for the 6445 [as well as all the 6442 varients as far as I know] which might help you sort this out- you can load your Vendor file and compare it to one of ours with Notepad++ [with a free plugin]. It will even indicate which settings are different between two files. Leave me a Private message if you want my email and/or phone #. Gene

Thank you Gene for the response! I did download Notepad++ upon your advice and will compare our vendor settings.

My control board and interface now seem to be coordinated properly so the laser head moves in the expected direction when I press the movement buttons on the interface, so that's a plus! I wired my laser tube and chiller last night and hope to test fire it this week! I appreciate everyone's help in getting this far!
